  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()

  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

• 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)

  For INTEGER type ResultSet.getObject() returns BigDecimal: dependent objects with integer identity cause type conversion error (need to fix SimpleQueryExecutor).

  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.

  Overrides:

  isKeyGeneratorSequenceTypeSupported in class GenericFactory

  Parameters:

  type - SQL type to check for support by sequence key generator.

  Returns:
