            SQLQuery               :DYNARRAY[] of CHAR;
            VAR outColumnCnt       :LONGINT;
            VAR outResultSetInst   :LONGINT) : BOOLEAN;

def vs.DBSQLExecute(database, SQLQuery):
    return (BOOLEAN, outColumnCnt, outResultSetInst)

Parameters

Example

PROCEDURE Test;

	colCnt, resSetInst, colIndex, rowIndex : LONGINT;
	colName, colValue : DYNARRAY [] OF CHAR;
BEGIN
	res := DBSQLExecuteDSN( 'My Building', '', '', 'SELECT * FROM Spaces', colCnt, resSetInst );

	rowIndex := 1;
	REPEAT
		FOR colIndex := 1 TO colCnt DO BEGIN
			res := DBSQLExecuteGet( resSetInst, colIndex, colName, colValue );

			AlrtDialog( Concat( 'Result: row=', rowIndex, ' col=', colIndex, ' colName=', colName, ' colValue=', colValue ) );
		END;

		rowIndex  := rowIndex  + 1;
	UNTIL NOT DBSQLExecuteNext( resSetInst );

	DBSQLExecuteDelete( resSetInst );
