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 interfacePersistenceFactory
- Overrides:
getFactoryName
in classGenericFactory
- Returns:
- The name of this factory
-
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 interfacePersistenceFactory
- Overrides:
getQueryExpression
in classGenericFactory
- Returns:
- New empty query expression
-
quoteName
Description copied from interface:PersistenceFactory
Returns the quoted identifier suitable for preventing conflicts between database identifiers and reserved keywords.- Specified by:
quoteName
in interfacePersistenceFactory
- Overrides:
quoteName
in classGenericFactory
- Parameters:
name
- The identifier (table, column, etc)- Returns:
- The quoted identifier
-
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.- Specified by:
getCallQuery
in interfacePersistenceFactory
- Overrides:
getCallQuery
in classBaseFactory
- Parameters:
call
- Stored procedure call (without "{call")paramTypes
- The types of the query parametersjavaClass
- The Java class of the query resultsfields
- The field namessqlTypes
- The field SQL types- Returns:
- null if this feature is not supported.
-
isKeyGeneratorIdentitySupported
public boolean isKeyGeneratorIdentitySupported()Description copied from class:GenericFactory
Does persistence factory support generation of unique keys with identity key generator?- Specified by:
isKeyGeneratorIdentitySupported
in interfacePersistenceFactory
- Overrides:
isKeyGeneratorIdentitySupported
in classGenericFactory
- Returns:
true
if persistence factory is able to generate unique keys with identity key generator,false
otherwise.
-
isKeyGeneratorIdentityTypeSupported
public boolean isKeyGeneratorIdentityTypeSupported(int type) Description copied from class:GenericFactory
Does identity key generator support generation of unique keys for the given SQL type?- Specified by:
isKeyGeneratorIdentityTypeSupported
in interfacePersistenceFactory
- Overrides:
isKeyGeneratorIdentityTypeSupported
in classGenericFactory
- Parameters:
type
- SQL type to check for support by identity key generator.- Returns:
true
if persistence factory is able to generate unique keys of given SQL type with identity key generator,false
otherwise.
-
getIdentitySelectString
Description copied from class:GenericFactory
Returns the database specific query string for retrieving last identity value.- Specified by:
getIdentitySelectString
in interfacePersistenceFactory
- Overrides:
getIdentitySelectString
in classGenericFactory
- Parameters:
tableName
- Name of the table from which identity needs to be fetched.columnName
- Name of the column from which identity needs to be fetched.- Returns:
- SQL Query string for fetching the identity value.
