isReturnResultSetSupported

public boolean isReturnResultSetSupported()
Description copied from interface: CallMetaDataProvider
Does this database support returning resultsets that should be retreived with the JDBC call Statement.getResultSet()

Specified by:
isReturnResultSetSupported in interface CallMetaDataProvider
Overrides:
isReturnResultSetSupported in class GenericCallMetaDataProvider

isRefCursorSupported

public boolean isRefCursorSupported()
Description copied from interface: CallMetaDataProvider
Does this database support returning resultsets as ref cursors to be retreived with CallableStatement.getObject(int) for the specified column.

Specified by:
isRefCursorSupported in interface CallMetaDataProvider
Overrides:

getRefCursorSqlType

public int getRefCursorSqlType()
Description copied from interface: CallMetaDataProvider
Get the Types type for columns that return resultsets as ref cursors if this feature is supported.

Specified by:
getRefCursorSqlType in interface CallMetaDataProvider
Overrides:
getRefCursorSqlType in class GenericCallMetaDataProvider

metaDataSchemaNameToUse

public String metaDataSchemaNameToUse(String schemaName)
Description copied from interface: CallMetaDataProvider
Provide any modification of the schema name passed in to match the meta data currently used. The reyurned value will be used for meta data lookups. This could include alterig the case used or providing a base schema if mone provided.

Specified by:
metaDataSchemaNameToUse in interface CallMetaDataProvider
Overrides:
metaDataSchemaNameToUse in class GenericCallMetaDataProvider

createDefaultOutParameter

public SqlParameter createDefaultOutParameter(String parameterName,
                                              CallParameterMetaData meta)
Description copied from interface: CallMetaDataProvider
Create a default out parameter based on the provided meta data. This is used when no expicit parameter declaration has been made.

Specified by:
createDefaultOutParameter in interface CallMetaDataProvider
Overrides:
createDefaultOutParameter in class GenericCallMetaDataProvider
Parameters:
parameterName - the name of the parameter
meta - meta data used for this call
Returns:
the configured SqlOutParameter

byPassReturnParameter

public boolean byPassReturnParameter(String parameterName)
Description copied from interface: CallMetaDataProvider
Should we bypass the return parameter with the specified name. This allows the database specific implementation to skip the processing for specific results returned by the database call.

Specified by:
byPassReturnParameter in interface CallMetaDataProvider
Overrides:
byPassReturnParameter in class GenericCallMetaDataProvider
