List of newScalarExpression() Examples

Examples of newScalarExpression()

org.datanucleus.store.mapped.mapping.JavaTypeMapping.newScalarExpression()
Creates a expression from a field name/table. e.g. tablename.fieldname; tablealias.fieldalias For use in TJDO-style JDOQL. This implementation just throws a NucleusException. @param qs The Query statement @param te the alias for the table @return A Scalar Expression
org.jpox.store.mapped.mapping.JavaTypeMapping.newScalarExpression()
Creates a expression from a field name/table. e.g. tablename.fieldname; tablealias.fieldalias @param qs The Query statement @param te the alias for the table @return A Scalar Expression
