Using IBM Informix Dynamic Server Version 10.00.FC9 I’m looking to set multiple field values

Using IBM Informix Dynamic Server Version 10.00.FC9

I’m looking to set multiple field values with one CASE block. Is this possible? Do I have to re-evaluate the same conditions for each field set?

I was thinking of something along these lines:

SELECT CASE WHEN p.id = 9238 THEN ('string',3) END (varchar_field, int_field);

Where the THEN section would define an ‘array’ of fields similar to the syntax of

INSERT INTO table (field1,field2) values (value1,value2)

Also, can it be done with a CASE block of an UPDATE statement?

UPDATE TABLE SET (field1,field2) = CASE WHEN p.id=9238 THEN (value1,value2) END;

    Normally, I’d ask for the version of Informix that you’re using, but it probably doesn’t matter much this time. The simple answer is ‘No’.

    A more complex answer might discuss using a row type constructor, but that probably isn’t what you want on the output. And, given the foregoing, then the UPDATE isn’t going to work (and would require an extra level of parentheses if it was going to).
