Retrieve a value inside a stored procedure and use it inside that stored procedure

Question

delimiter //
CREATE DEFINER=root@localhost PROCEDUREgetData(IN templateName VARCHAR(45),IN templateVersion VARCHAR(45),IN userId VARCHAR(45))
BEGIN
set @version = CONCAT("SELECT saveOEMsData_answersVersion FROMsaveOEMsData WHERE saveOEMsData_templateName = '",templateName,"' ANDsaveOEMsData_templateVersion = ",templateVersion," AND saveOEMsData_userId= ",userId);
PREPARE s1 from @version;
EXECUTE S1;
END // delimiter ;

I am retrieving saveOEMsData_answersVersion, but I have to use it in an IF loop, as in if the version == 1, then I would use a query, else I would use something else. But I am not able to use the version. Could someone help with this?? I am only able to print but not able to use the version for data manipulation. The procedure works fine but I am unable to proceed to next step which is the if condition.

The if condition would have something like the below mentioned.

IF(ver == 1) THEN SELECT "1";
END IF;

IF is allowed inside a Procedure, you can not use IF inside SQL, in SQL you can use CASE, but that doesn't have the same abilities.

Build a second procedure to handle the IF/Then for the results of getData
