MySQLFactory

public MySQLFactory()
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

adjustSqlType

public java.lang.Class adjustSqlType(java.lang.Class sqlType)
For CLOB type ResultSet.setClob() is not supported yet by mm.MySql JDBC driver. BLOB support is buggy in MM.MySQL 2.0.3: it handles NULL values in incorrect way.

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.
