第2行的列'descr'的数据太长

Question

When I try this sql statement to execute

update claim cl set search_field = (select  concat(cl.claim_description,' ', cl.legal_basis,' ',co.name) from contact co where cl.probable=1 and cl.search_field is null and co.id=cl.contact_id)

I get error above, and there is no column named descr . There is column named claim_description but it isn't descr

Does anyone have hint? Thank you

Answer 1

Instead of a correlated subquery in an UPDATE statement try:

UPDATE claim cl, contact co
SET cl.search_field = CONCAT (cl.claim_description,' ',cl.legal_basis,' ',co.NAME)          
WHERE cl.probable = 1
    AND cl.search_field IS NULL
    AND co.id = cl.contact_id

Thanks for your help, I found solution for this. Trigger on update was problem it was trying to update variable descr which was too short. It looks like brushing teeth really helps in programming :)
