org.datanucleus.store.rdbms.sql.expression.TemporalSubqueryExpression
Temporal expression to wrap a subquery. The subquery SQLStatement should return a temporal value. This is possible with a subquery like MAX(date), MIN(date).

            {
                JavaTypeMapping subMapping = 
                    ((StatementMappingIndex)subqueryResultMapping.getMappingForResultExpression(0)).getMapping();
                if (subMapping instanceof TemporalMapping)
                {
                    subExpr = new TemporalSubqueryExpression(stmt, subStmt);
                }
                else if (subMapping instanceof StringMapping)
                {
                    subExpr = new StringSubqueryExpression(stmt, subStmt);
                }
