PreparedStatement

addBatch

abstract fun addBatch(): Unit

Adds a set of parameters to this PreparedStatement object's batch of commands.

clearParameters

abstract fun clearParameters(): Unit

Clears the current parameter values immediately.

In general, parameter values remain in force for repeated use of a statement. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling the method clearParameters.

execute

abstract fun execute(): Boolean

Executes the SQL statement in this PreparedStatement object, which may be any kind of SQL statement. Some prepared statements return multiple results; the execute method handles these complex statements as well as the simpler form of statements handled by the methods executeQuery and executeUpdate.

The execute method returns a boolean to indicate the form of the first result. You must call either the method getResultSet or getUpdateCount to retrieve the result; you must call getMoreResults to move to any subsequent result(s).

executeQuery

abstract fun executeQuery(): ResultSet!

Executes the SQL query in this PreparedStatement object and returns the ResultSet object generated by the query.

executeUpdate

abstract fun executeUpdate(): Int

Executes the SQL statement in this PreparedStatement object, which must be an SQL Data Manipulation Language (DML) statement, such as INSERT, UPDATE or DELETE; or an SQL statement that returns nothing, such as a DDL statement.

getMetaData

abstract fun getMetaData(): ResultSetMetaData!

Retrieves a ResultSetMetaData object that contains information about the columns of the ResultSet object that will be returned when this PreparedStatement object is executed.

Because a PreparedStatement object is precompiled, it is possible to know about the ResultSet object that it will return without having to execute it. Consequently, it is possible to invoke the method getMetaData on a PreparedStatement object rather than waiting to execute it and then invoking the ResultSet.getMetaData method on the ResultSet object that is returned.

NOTE: Using this method may be expensive for some drivers due to the lack of underlying DBMS support.

getParameterMetaData

abstract fun getParameterMetaData(): ParameterMetaData!

Retrieves the number, types and properties of this PreparedStatement object's parameters.

setArray

abstract fun setArray(
    parameterIndex: Int, 
    x: Array!
): Unit

Sets the designated parameter to the given java.sql.Array object. The driver converts this to an SQL ARRAY value when it sends it to the database.

abstract fun setAsciiStream(
    parameterIndex: Int, 
    x: InputStream!, 
    length: Int
): Unit

Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large ASCII value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream. Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

abstract fun setAsciiStream(
    parameterIndex: Int, 
    x: InputStream!, 
    length: Long
): Unit

When a very large ASCII value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream. Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

setAsciiStream

abstract fun setAsciiStream(

): Unit

Sets the designated parameter to the given input stream. When a very large ASCII value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream. Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setAsciiStream which takes a length parameter.

setBigDecimal

abstract fun setBigDecimal(
    parameterIndex: Int, 
    x: BigDecimal!
): Unit

Sets the designated parameter to the given java.math.BigDecimal value. The driver converts this to an SQL NUMERIC value when it sends it to the database.

abstract fun setBinaryStream(
    parameterIndex: Int, 
    x: InputStream!, 
    length: Int
): Unit

Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large binary value is input to a LONGVARBINARY parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

setBinaryStream

abstract fun setBinaryStream(
    parameterIndex: Int, 
    x: InputStream!, 
    length: Long
): Unit

Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large binary value is input to a LONGVARBINARY parameter, it may be more practical to send it via a java.io.InputStream object.

    x: InputStream!
): Unit

Sets the designated parameter to the given input stream. When a very large binary value is input to a LONGVARBINARY parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setBinaryStream which takes a length parameter.

setBlob

abstract fun setBlob(
    parameterIndex: Int, 
    x: Blob!
): Unit

Sets the designated parameter to the given java.sql.Blob object. The driver converts this to an SQL BLOB value when it sends it to the database.

setBlob

abstract fun setBlob(
    parameterIndex: Int, 
    inputStream: InputStream!, 
    length: Long
): Unit

Sets the designated parameter to a InputStream object. The inputstream must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setBinaryStream (int, InputStream, int) method because it informs the driver that the parameter value should be sent to the server as a BLOB. When the setBinaryStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARBINARY or a BLOB

setBlob

abstract fun setBlob(
    parameterIndex: Int, 
    inputStream: InputStream!
): Unit

Sets the designated parameter to a InputStream object. This method differs from the setBinaryStream (int, InputStream) method because it informs the driver that the parameter value should be sent to the server as a BLOB.

setBoolean

abstract fun setBoolean(
    parameterIndex: Int, 
    x: Boolean
): Unit

setBytes

abstract fun setBytes(
    parameterIndex: Int, 
    x: ByteArray!
): Unit

Sets the designated parameter to the given Java array of bytes. The driver converts this to an SQL VARBINARY or LONGVARBINARY (depending on the argument's size relative to the driver's limits on VARBINARY values) when it sends it to the database.

setCharacterStream

abstract fun setCharacterStream(
    parameterIndex: Int, 
    reader: Reader!, 
    length: Int
): Unit

Sets the designated parameter to the given Reader object, which is the given number of characters long. When a very large UNICODE value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.Reader object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from UNICODE to the database char format.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

setCharacterStream

abstract fun setCharacterStream(
    parameterIndex: Int, 
    reader: Reader!, 
    length: Long
): Unit

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

setCharacterStream

abstract fun setCharacterStream(
    parameterIndex: Int, 
    reader: Reader!
): Unit

The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from UNICODE to the database char format.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setCharacterStream which takes a length parameter.

setClob

abstract fun setClob(
    parameterIndex: Int, 
    x: Clob!
): Unit

Sets the designated parameter to the given java.sql.Clob object. The driver converts this to an SQL CLOB value when it sends it to the database.

setClob

abstract fun setClob(
    parameterIndex: Int, 
    reader: Reader!, 
    length: Long
): Unit

Sets the designated parameter to a Reader object. The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a CLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARCHAR or a CLOB

setClob

abstract fun setClob(
    parameterIndex: Int, 
    reader: Reader!
): Unit

Sets the designated parameter to a Reader object. This method differs from the setCharacterStream (int, Reader) method because it informs the driver that the parameter value should be sent to the server as a CLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARCHAR or a CLOB

setDate

abstract fun setDate(
    parameterIndex: Int, 
    x: Date!
): Unit

Sets the designated parameter to the given java.sql.Date value using the default time zone of the virtual machine that is running the application. The driver converts this to an SQL DATE value when it sends it to the database.

setDate

abstract fun setDate(
    parameterIndex: Int, 
    x: Date!, 
    cal: Calendar!
): Unit

Sets the designated parameter to the given java.sql.Date value, using the given Calendar object. The driver uses the Calendar object to construct an SQL DATE value, which the driver then sends to the database. With a Calendar object, the driver can calculate the date taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

setDouble

abstract fun setDouble(
    parameterIndex: Int, 
    x: Double
): Unit

Sets the designated parameter to the given Java double value. The driver converts this to an SQL DOUBLE value when it sends it to the database.

setNCharacterStream

abstract fun setNCharacterStream(
    parameterIndex: Int, 
    value: Reader!, 
    length: Long
): Unit

setNCharacterStream

abstract fun setNCharacterStream(
    parameterIndex: Int, 
    value: Reader!
): Unit

Sets the designated parameter to a Reader object. The Reader reads the data till end-of-file is reached. The driver does the necessary conversion from Java character format to the national character set in the database.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setNCharacterStream which takes a length parameter.

setNClob

abstract fun setNClob(
    parameterIndex: Int, 
    value: NClob!
): Unit

Sets the designated parameter to a java.sql.NClob object. The driver converts this to a SQL NCLOB value when it sends it to the database.

setNClob

abstract fun setNClob(
    parameterIndex: Int, 
    reader: Reader!, 
    length: Long
): Unit

Sets the designated parameter to a Reader object. The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a NCLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGNVARCHAR or a NCLOB

setNClob

abstract fun setNClob(
    parameterIndex: Int, 
    reader: Reader!
): Unit

Sets the designated parameter to a Reader object. This method differs from the setCharacterStream (int, Reader) method because it informs the driver that the parameter value should be sent to the server as a NCLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGNVARCHAR or a NCLOB

Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setNClob which takes a length parameter.

setNString

abstract fun setNString(
    parameterIndex: Int, 
    value: String!
): Unit

Sets the designated paramter to the given String object. The driver converts this to a SQL NCHAR or NVARCHAR or LONGNVARCHAR value (depending on the argument's size relative to the driver's limits on NVARCHAR values) when it sends it to the database.

setNull

abstract fun setNull(
    parameterIndex: Int, 
    sqlType: Int
): Unit

Sets the designated parameter to SQL NULL.

Note: You must specify the parameter's SQL type.

setNull

abstract fun setNull(
    parameterIndex: Int, 
    sqlType: Int, 
    typeName: String!
): Unit

Sets the designated parameter to SQL NULL. This version of the method setNull should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.

setObject

abstract fun setObject(
    parameterIndex: Int, 
    x: Any!, 
    targetSqlType: Int
): Unit

Sets the value of the designated parameter with the given object. This method is like the method setObject above, except that it assumes a scale of zero.

setObject

abstract fun setObject(
    parameterIndex: Int, 
    x: Any!
): Unit

Sets the value of the designated parameter using the given object. The second parameter must be of type Object; therefore, the java.lang equivalent objects should be used for built-in types.

The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database.

Note that this method may be used to pass datatabase- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface SQLData, the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, RowId, SQLXML or Array, the driver should pass it to the database as a value of the corresponding SQL type.

Note: Not all databases allow for a non-typed Null to be sent to the backend. For maximum portability, the setNull or the setObject(int parameterIndex, Object x, int sqlType) method should be used instead of setObject(int parameterIndex, Object x).

Note: This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

setObject

abstract fun setObject(
    parameterIndex: Int, 
    x: Any!, 
    targetSqlType: Int, 
    scaleOrLength: Int
): Unit

Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, the java.lang equivalent objects should be used. If the second argument is an InputStream then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate a SQLException when the prepared statement is executed.

The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

Note that this method may be used to pass database-specific abstract data types.

setRef

abstract fun setRef(
    parameterIndex: Int, 
    x: Ref!
): Unit

Sets the designated parameter to the given REF(<structured-type>) value. The driver converts this to an SQL REF value when it sends it to the database.

setRowId

abstract fun setRowId(
    parameterIndex: Int, 
    x: RowId!
): Unit

Sets the designated parameter to the given java.sql.RowId object. The driver converts this to a SQL ROWID value when it sends it to the database

setSQLXML

abstract fun setSQLXML(
    parameterIndex: Int, 
    xmlObject: SQLXML!
): Unit

Sets the designated parameter to the given java.sql.SQLXML object. The driver converts this to an SQL XML value when it sends it to the database.

setString

abstract fun setString(
    parameterIndex: Int, 
    x: String!
): Unit

Sets the designated parameter to the given Java String value. The driver converts this to an SQL VARCHAR or LONGVARCHAR value (depending on the argument's size relative to the driver's limits on VARCHAR values) when it sends it to the database.

setTime

abstract fun setTime(
    parameterIndex: Int, 
    x: Time!
): Unit

Sets the designated parameter to the given java.sql.Time value. The driver converts this to an SQL TIME value when it sends it to the database.

setTime

abstract fun setTime(
    parameterIndex: Int, 
    x: Time!, 
    cal: Calendar!
): Unit

Sets the designated parameter to the given java.sql.Time value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIME value, which the driver then sends to the database. With a Calendar object, the driver can calculate the time taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

setTimestamp

abstract fun setTimestamp(
    parameterIndex: Int, 
    x: Timestamp!
): Unit

Sets the designated parameter to the given java.sql.Timestamp value. The driver converts this to an SQL TIMESTAMP value when it sends it to the database.

setTimestamp

abstract fun setTimestamp(
    parameterIndex: Int, 
    x: Timestamp!, 
    cal: Calendar!
): Unit

Sets the designated parameter to the given java.sql.Timestamp value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIMESTAMP value, which the driver then sends to the database. With a Calendar object, the driver can calculate the timestamp taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

setURL

abstract fun setURL(
    parameterIndex: Int, 
    x: URL!
): Unit

Sets the designated parameter to the given java.net.URL value. The driver converts this to an SQL DATALINK value when it sends it to the database.

setUnicodeStream

abstract fun setUnicodeStream(
    parameterIndex: Int, 
    x: InputStream!, 
    length: Int
): Unit

Deprecated: Use setCharacterStream

Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large Unicode value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from Unicode to the database char format. The byte format of the Unicode stream must be a Java UTF-8, as defined in the Java Virtual Machine Specification.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
