PostgreSQLFactory

public PostgreSQLFactory()
Method Detail

getFactoryName

public java.lang.String getFactoryName()
Description copied from interface: PersistenceFactory
Returns the name of this factory. A descriptive name that indicates the type of supported database server or SQL syntax.

Specified by:
getFactoryName in interface PersistenceFactory
Overrides:
getFactoryName in class GenericFactory
Returns:
The name of this factory

getQueryExpression

public QueryExpression getQueryExpression()
Description copied from interface: PersistenceFactory
Returns a new empty query expression suitable for the underlying SQL engine. The implementation will construct SQL query statements in the preferred syntax.

Specified by:
getQueryExpression in interface PersistenceFactory
Overrides:
getQueryExpression in class GenericFactory
Returns:
New empty query expression

isDuplicateKeyException

public java.lang.Boolean isDuplicateKeyException(java.lang.Exception ex)
Determine if the given SQLException is DuplicateKeyException.

Specified by:
isDuplicateKeyException in interface PersistenceFactory
Overrides:
isDuplicateKeyException in class GenericFactory
Returns:
Boolean.TRUE means "yes", Boolean.FALSE means "no", null means "cannot determine".

quoteName

public java.lang.String quoteName(java.lang.String name)
Description copied from interface: PersistenceFactory
Returns the quoted identifier suitable for preventing conflicts between database identifiers and reserved keywords.

Specified by:
quoteName in interface PersistenceFactory
Overrides:
quoteName in class GenericFactory
Parameters:
name - The identifier (table, column, etc)
Returns:
The quoted identifier

getCallQuery

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

Specified by:
getCallQuery in interface PersistenceFactory
Overrides:
getCallQuery in class BaseFactory
Parameters:
call - Stored procedure call (without "{call")
paramTypes - The types of the query parameters
javaClass - The Java class of the query results
fields - The field names
sqlTypes - The field SQL types
Returns:
null if this feature is not supported.

adjustSqlType

public java.lang.Class adjustSqlType(java.lang.Class sqlType)
Description copied from class: BaseFactory
Some databases has some problems with some SQL types. Usually it is enough to merely replace one SQL type by another.

Specified by:
adjustSqlType in interface PersistenceFactory
Overrides:
adjustSqlType in class BaseFactory
Parameters:
sqlType - The correspondent Java class for the SQL type in mapping.xml
Returns:
The correspondent Java class for the SQL type that should be used instead.
