SDBC provides a stored procedure SQL escape that allows stored procedures to be called in a standard way for all RDBMSs. This escape syntax has one form that includes a result parameter and one that does not. If used, the result parameter must be registered as an OUT parameter. The other parameters can be used for input, output, or both. Parameters are referred to sequentially, by number. The first parameter is 1.
*/ published interface XOutParameters: com::sun::star::uno::XInterface { /** registers the designated output parameter. This version of the method com::sun::star::sdbc::XOutParameters::registerOutParameter() should be used for a user-named or REF output parameter. Examples of user-named types include: STRUCT, DISTINCT, OBJECT, and named array types.
Before executing a stored procedure call, you must explicitly
call
com::sun::star::sdbc::XOutParameters::registerOutParameter()
to register the type from
com::sun::star::sdbc::DataType
for each OUT parameter.
For a user-named parameter the fully-qualified SQL type name of the
parameter should also be given, while a REF parameter requires that the
fully-qualified type name of the referenced type be given.
An SDBC driver that does not need the type code and type name information
may ignore it. To be portable, however, applications should always provide
these values for user-named and REF parameters.
Although it is intended for user-named and REF parameters, this method may be used to register a parameter of any SDBC type. If the parameter does not have a user-named or REF type, the typeName parameter is ignored.
Note: When reading the value of an out parameter, you
must use the
getXXX
method whose type XXX corresponds to the
parameter's registered SQL type.
parameterIndex
to the SDBC type sqlType
. All
OUT parameters must be registered before a stored procedure is executed.
The SDBC type specified by
sqlType
for an OUT parameter determines the type that must be used in the
get
method to read the value of that parameter.
This version of
com::sun::star::sdbc::XOutParameters::registerOutParameter()
should be
used when the parameter is of SDBC type
com::sun::star::sdbc::DataType::NUMERIC
or com::sun::star::sdbc::DataType::DECIMAL.
@param parameterIndex
the first parameter is 1, the second is 2, ...
@param sqlType
the type of the column to register
@param scale
the scale of the type
@throws SQLException
if a database access error occurs.
