You can use casting in the select clause like   SELECT id  name  CAST hide AS BOOLEAN  FROM table name

If you want the column as string values  then   SELECT id  name  CASE WHEN hide   0 THEN  false  ELSE  true  END AS hide   FROM anonymous table   If the DBMS supports BOOLEAN  you can use instead   SELECT id  name  CASE WHEN hide   0 THEN false ELSE true END AS hide   FROM anonymous table   That s the same except that the quotes around the names false and true were removed

You have a number of choices    Join with a domain table with TRUE  FALSE Boolean value  Use  as pointed in this answer   SELECT CASE WHEN hide   0 THEN FALSE ELSE TRUE END FROM   Or if Boolean is not supported   SELECT CASE WHEN hide   0 THEN  false  ELSE  true  END FROM

I saying that the case statement is wrong but this can be a good solution instead  If you choose to use the CASE statement  you have to make sure that at least one of the CASE condition is matched  Otherwise  you need to define an error handler to catch the error  Recall that you don   t have to do this with the IF statement   SELECT if hide   0 FALSE TRUE  col FROM tbl   for BOOLEAN Value return   or  SELECT if hide   0  FALSE   TRUE   col FROM tbl   for string Value return

I got the solution      SELECT     CASE status       WHEN  VS  THEN  validated by subsidiary        WHEN  NA  THEN  not acceptable        WHEN  D   THEN  delisted        ELSE  validated     END AS STATUS    FROM SUPP STATUS   This is using the CASE This is another to manipulate the selected value for more that two options
