Modifier and TypeMethodDescriptionClass
<?> adjustSqlType
(Class<?> sqlType) For INTEGER type ResultSet.getObject() returns BigDecimal: dependent objects with integer identity cause type conversion error (need to fix SimpleQueryExecutor).getCallQuery
(String call, Class<?>[] paramTypes, Class<?> javaClass, String[] fields, int[] sqlTypes) Needed to process OQL queries of "CALL" type (using stored procedure call).Returns the name of this factory.Returns a new empty query expression suitable for the underlying SQL engine.getSequenceBeforeSelectString
(String seqName, String tableName, int increment) Returns the database specific SELECT query string for fetching identity before the next INSERT statement gets executed.getSequenceNextValString
(String seqName) Returns the database engine specific string to fetch sequence next value.boolean
isKeyGeneratorSequenceSupported
(boolean returning, boolean trigger) Does persistence factory support generation of new key at the time of new object creation with sequence key generator?boolean
isKeyGeneratorSequenceTypeSupported
(int type) Does Sequence key generator support generation of key for the given SQL type?Returns the quoted identifier suitable for preventing conflicts between database identifiers and reserved keywords.Methods inherited from class org.castor.cpa.persistence.sql.driver.GenericFactory

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.
-
adjustSqlType
For INTEGER type ResultSet.getObject() returns BigDecimal: dependent objects with integer identity cause type conversion error (need to fix SimpleQueryExecutor).- Specified by:
adjustSqlType
in interfacePersistenceFactory
- Overrides:
adjustSqlType
in classBaseFactory
- 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.
-
isKeyGeneratorSequenceSupported
public boolean isKeyGeneratorSequenceSupported(boolean returning, boolean trigger) Description copied from class:GenericFactory
Does persistence factory support generation of new key at the time of new object creation with sequence key generator?- Specified by:
isKeyGeneratorSequenceSupported
in interfacePersistenceFactory
- Overrides:
isKeyGeneratorSequenceSupported
in classGenericFactory
- Parameters:
returning
- Return generated key value with insert statement?trigger
- Use a database trigger to generate key?- Returns:
true
if persistence factory is able to generate key with sequence key generator,false
otherwise.
-
isKeyGeneratorSequenceTypeSupported
public boolean isKeyGeneratorSequenceTypeSupported(int type) Does Sequence key generator support generation of key for the given SQL type?- Specified by:
isKeyGeneratorSequenceTypeSupported
in interfacePersistenceFactory
- Overrides:
isKeyGeneratorSequenceTypeSupported
in classGenericFactory
- Parameters:
type
- SQL type to check for support by sequence key generator.- Returns:
true
if persistence factory is able to generate key of given SQL type with sequence key generator,false
otherwise.
-
getSequenceNextValString
Description copied from class:GenericFactory
Returns the database engine specific string to fetch sequence next value.- Specified by:
getSequenceNextValString
in interfacePersistenceFactory
- Overrides:
getSequenceNextValString
in classGenericFactory
- Parameters:
seqName
- Name of the sequence.- Returns:
- String to fetch sequence next value.
-
getSequenceBeforeSelectString
Description copied from class:GenericFactory
Returns the database specific SELECT query string for fetching identity before the next INSERT statement gets executed.- Specified by:
getSequenceBeforeSelectString
in interfacePersistenceFactory
- Overrides:
getSequenceBeforeSelectString
in classGenericFactory
- Parameters:
seqName
- Name of sequence.tableName
