Detailed Description

represents a precompiled SQL statement.

A SQL statement is pre-compiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

Note: The setXXX methods for setting IN parameter values must specify types that are compatible with the defined SQL type of the input parameter. For instance, if the IN parameter has SQL type Integer, then the method com::sun::star::sdbc::XParameters::setInt() should be used.

If arbitrary parameter type conversions are required, the method com::sun::star::sdbc::XParameters::setObject() should be used with a target SQL type.

Example of setting a parameter; con is an active connection.

1 pstmt = con.prepareStatement("UPDATE EMPLOYEES SET SALARY = ? WHERE ID = ?")
2 pstmt.setDouble(1, 153833.00)
3 pstmt.setLong(2, 110592)

Only one com::sun::star::sdbc::ResultSet per com::sun::star::sdbc::Statement can be open at any point in time. Therefore, if the reading of one ResultSet is interleaved with the reading of another, each must have been generated by different Statements. All statement execute methods implicitly close a statement's current ResultSet if an open one exists.

Exported Interfaces

optional for implementation, controls the releasing of resources and the notification of registered listeners.

could be used for canceling the execution of SQL statements, if both the DBMS and the driver support aborting an SQL statement.

The implementation is optional.

interface XCloseable

freeing all resources of a statement.

A related result set will be freed as well.

interface XMultipleResults

covers the handling of multiple results after executing an SQL command.

interface XParameters

is used for setting parameters before execution of the precompiled statement.

interface XPreparedBatchExecution
optional

provides the ability of batch execution.

This interface is optional for execution.

A driver implementing batch execution must return TRUE for com::sun::star::sdbc::XDatabaseMetaData::supportsBatchUpdates()

interface XPreparedStatement

is the interface for executing SQL prepared commands.

provides access to the description of the result set which would be generated by executing the PreparedStatement.

interface XWarningsSupplier

controls the chaining of warnings, which may occur on every call to the connected database.

Chained warnings from previous calls will be cleared before processing a new call.

Member Data Documentation

string CursorName
property

defines the SQL cursor name that will be used by subsequent Statement execute methods.

This name can then be used in SQL positioned update/delete statements to identify the current row in the ResultSet generated by this statement. If the database does not support positioned update/delete, this property is a noop. To ensure that a cursor has the proper isolation level to support updates, the cursor's SELECT statement should be of the form "select for update ...". If the "for update" phrase is omitted, positioned updates may fail.

Note: By definition, positioned update/delete execution must be done by a different Statement than the one which generated the ResultSet being used for positioning. Also, cursor names must be unique within a connection.

long FetchDirection
property

retrieves the direction for fetching rows from database tables that is the default for result sets generated from this Statement object.

If this Statement object has not set a fetch direction, the return value is implementation-specific.

long FetchSize
property

retrieves the number of result set rows that is the default fetch size for result sets generated from this Statement object.

If this Statement object has not set a fetch size, the return value is implementation-specific.

long MaxFieldSize
property

returns the maximum number of bytes allowed for any column value.

This limit is the maximum number of bytes that can be returned for any column value. The limit applies only to com::sun::star::sdbc::DataType::BINARY , com::sun::star::sdbc::DataType::VARBINARY , com::sun::star::sdbc::DataType::LONGVARBINARY , com::sun::star::sdbc::DataType::CHAR , com::sun::star::sdbc::DataType::VARCHAR , and com::sun::star::sdbc::DataType::LONGVARCHAR columns. If the limit is exceeded, the excess data is silently discarded.

There is no limitation, if set to zero.

long MaxRows
property

retrieves the maximum number of rows that a ResultSet can contain.

If the limit is exceeded, the excess rows are silently dropped.
There is no limitation, if set to zero.

long QueryTimeOut
property

retrieves the number of seconds the driver will wait for a Statement to execute.

If the limit is exceeded, a SQLException is thrown. There is no limitation, if set to zero.

long ResultSetConcurrency
property

retrieves the result set concurrency.

com::sun::star::sdbc::ResultSetConcurrency
long ResultSetType
property
