A MySQL IF condition

Question

In my query I have an IF statement:

IF(friend.block, 'yes', 'no') 

where friend.block value is 0 or 1.. but either way its putting 'yes'.. any idea?

Answer 1

friend.block should be of type INTEGER for that to work or you have to put a comparaison there:

IF(friend.block != 0, 'yes', 'no')

Answer 2

Reference: MySQL Reference

The syntax is:

IF (friend.block = 1) THEN
    'Yes'
ELSE
    'No'
END IF

You can use case statement:

CASE friend.block WHEN 1 THEN 'Yes' WHEN 0 THEN 'No' END
