Method Details

adjustSqlType

public Class adjustSqlType(Class sqlType)
For INTEGER type ResultSet.getObject() returns BigDecimal: dependent objects with integer identity cause type conversion error (need to fix SimpleQueryExecutor).
Overrides:
adjustSqlType in interface BaseFactory

getCallQuery

public PersistenceQuery getCallQuery(String call,
                                     Class[] paramTypes,
                                     Class javaClass,
                                     String[] fields,
                                     int[] sqlTypes)
Needed to process OQL queries of "CALL" type (using stored procedure call). This feature is specific for JDO.
Overrides:
getCallQuery in interface BaseFactory

Returns:
null if this feature is not supported.
