I have a DB2 query and i am selecting columns like below:
Code:

 SELECT EMPNO,EMPNAME,HIKEDATE FROM A
 WHERE HIKEDATE = 1;                             

I am getting the output as :
Code:

1   A   1

I am getting SQL error -104 .Is it possible to have DISTINCT for more than 1 column in a Single Query ? Please help me out in the correct Query:
Code:

SELECT DISTINCT(EMPNO, EMPNAME, HIKEDATE)
FROM A
WHERE HIKEDATE = 1

Code:

QUERY MESSAGES:                                 
SQL error at or before ,  (line 1, position 22).

yadav2005,

Remove the brackets and try like this

Code:

SELECT DISTINCT EMPNO,EMPNAME,HIKEDATE
  FROM A                             
 WHERE HIKEDATE = 1;
