Class SQLServerStatement

java.lang.Object

com.microsoft.sqlserver.jdbc.SQLServerStatement

All Implemented Interfaces:

ISQLServerStatement, AutoCloseable, Statement, Wrapper

Direct Known Subclasses:

SQLServerPreparedStatement

public class SQLServerStatement
extends Object
implements ISQLServerStatement

SQLServerStatment provides the basic implementation of JDBC statement functionality. It also provides a number of base class implementation methods for the JDBC prepared statement and callable Statements. SQLServerStatement's basic role is to execute SQL statements and return update counts and resultset rows to the user application. Documentation for specific public methods that are undocumented can be found under Sun's standard JDBC documentation for class java.sql.Statement. Those methods are part of Sun's standard JDBC documentation and therefore their documentation is not duplicated here.

Implementation Notes

Fetching Result sets

The queries first rowset is available immediately after the executeQuery. The first rs.next() does not make a server round trip. For non server side resultsets the entire result set is in the rowset. For server side result sets the number of rows in the rowset is set with nFetchSize

The API javadoc for JDBC API methods that this class implements are not repeated here. Please see Sun's JDBC API interfaces javadoc for those details.

setResponseBuffering

public final void setResponseBuffering(String value)
                                throws SQLServerException

Description copied from interface: ISQLServerStatement

Sets the response buffering mode for this SQLServerStatement object to case-insensitive String full or adaptive.

Response buffering controls the driver's buffering of responses from SQL Server.

Possible values are:

"full" - Fully buffer the response at execution time.

"adaptive" - Data Pipe adaptive buffering

Specified by:

setResponseBuffering in interface ISQLServerStatement

Parameters:

value - A String that contains the response buffering mode. The valid mode can be one of the following case-insensitive Strings: full or adaptive.

Throws:

SQLServerException - If there are any errors in setting the response buffering mode.

getResponseBuffering

public final String getResponseBuffering()
                                  throws SQLServerException

Description copied from interface: ISQLServerStatement

Retrieves the response buffering mode for this SQLServerStatement object.

Specified by:

getResponseBuffering in interface ISQLServerStatement

Returns:

A String that contains a lower-case full or adaptive.

Throws:

SQLServerException - If there are any errors in retrieving the response buffering mode.
