IIF
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The IIF() function checks if the first argument is TRUE to produce the second argument, or the third argument otherwise. It works in a similar way as the NVL2 function or the CASE expression
SELECT iif(1 = 1, 3, 4), iif(1 = 2, 3, 4);
create.select( iif(inline(1).eq(inline(1)), inline(3), inline(4)) iif(inline(1).eq(inline(2)), inline(3), inline(4))).fetch();
The result being
+-----+-----+ | iif | iif | +-----+-----+ | 3 | 4 | +-----+-----+
