Example 2
public Type getReturnType(Type columnType, Mapping mapping) throws QueryException {
	int[] sqlTypes;
	try {
		sqlTypes = columnType.sqlTypes( mapping );
	}
	catch ( MappingException me ) {
		throw new QueryException( me );
	}
	if ( sqlTypes.length != 1 ) throw new QueryException( "multi-column type in avg()" );
	return Hibernate.DOUBLE;
}
 
Example 3
public Type getReturnType(Type columnType, Mapping mapping) {

	int[] sqlTypes;
	try {
		sqlTypes = columnType.sqlTypes( mapping );
	}
	catch ( MappingException me ) {
		throw new QueryException( me );
	}
	if ( sqlTypes.length != 1 ) throw new QueryException( "multi-column type in sum()" );
	int sqlType = sqlTypes[0];

	// First allow the actual type to control the return value. (the actual underlying sqltype could actually be different)
	if ( columnType == Hibernate.BIG_INTEGER ) {
		return Hibernate.BIG_INTEGER;
	}
	else if ( columnType == Hibernate.BIG_DECIMAL ) {
		return Hibernate.BIG_DECIMAL;

		return Hibernate.LONG;
	}
	else if ( columnType == Hibernate.FLOAT || columnType == Hibernate.DOUBLE) {
		return Hibernate.DOUBLE;
	}

	// finally use the sqltype if == on Hibernate types did not find a match.
	if ( sqlType == Types.NUMERIC ) {
		return columnType; //because numeric can be anything
	}
	else if ( sqlType == Types.FLOAT || sqlType == Types.DOUBLE || sqlType == Types.DECIMAL || sqlType == Types.REAL) {

	}
	else if ( sqlType == Types.BIGINT || sqlType == Types.INTEGER || sqlType == Types.SMALLINT || sqlType == Types.TINYINT ) {
		return Hibernate.LONG;
	}
	else {

Example 4
private Type resolveDataType() {

	//      can't think of a situation where arithmetic expression between multi-column mappings
	//      makes any sense.
	Node lhs = getLeftHandOperand();

Example 5
private Type resolveDateTimeArithmeticResultType(Type lhType, Type rhType) {
	// here, we work under the following assumptions:
	//      ------------ valid cases --------------------------------------
	//      1) datetime + {something other than datetime} : always results
	//              in a datetime ( db will catch invalid conversions )
	//      2) datetime - datetime : always results in a DOUBLE
	//      3) datetime - {something other than datetime} : always results
	//              in a datetime ( db will catch invalid conversions )
	//      ------------ invalid cases ------------------------------------
	//      4) datetime + datetime
	//      5) {something other than datetime} - datetime
	//      6) datetime * {any type}
	//      7) datetime / {any type}
	//      8) {any type} / datetime
	// doing so allows us to properly handle parameters as either the left
	// or right side here in the majority of cases
	boolean lhsIsDateTime = isDateTimeType( lhType );
	boolean rhsIsDateTime = isDateTimeType( rhType );

	// handle the (assumed) valid cases:
	// #1 - the only valid datetime addition synatx is one or the other is a datetime (but not both)
	if ( getType() == HqlSqlTokenTypes.PLUS ) {
		// one or the other needs to be a datetime for us to get into this method in the first place...
		return lhsIsDateTime ? lhType : rhType;
	}
	else if ( getType() == HqlSqlTokenTypes.MINUS ) {
		// #3 - note that this is also true of "datetime - :param"...
