Hello! 

Does anyone know how to include a variable to a textstring? 

My attempts don't seem to succeed.

If you want to concatenate strings in SCL, with casting from integer (or others) to string, you must use the properly instructions:

#sQuery := CONCAT(IN1 := 'INSERT INTO .... VALUES (', IN2 := INT_TO_STRING(#iValue01));
#sQuery := CONCAT(IN1 := sQuery, IN2 := ') ...');
