Question

I have a case statement, however; I’m getting two erros. I can’t seem to find the answer to the fix the errors.

SELECT #TMP.webid_Val = CASE #TMP.webid 
when 'NULL' then 'NOT COMPLIANT'
else 'COMPLIANT'
end
FROM #TMP

**Incorrect syntax near FROM. Expecting CONVERSATION

Incorrect syntax near =**

#TMP is the temporary table.
webid is the value to be looked at for the condition
webid_val is the column who’s value will be changed.

Any help would be appreciated.

Answer 1

(The following answer assumes Sql Server)
You cannot do an update with a select statement.

If you are trying to return data to a client application or user, use

SELECT webid_Val = CASE 
    WHEN #TMP.webid IS NULL then 'NOT COMPLIANT'
    ELSE 'COMPLIANT'
END
FROM #TMP

or if you’re trying to update data in the original temp table, use the following:

UPDATE #tmp SET 
webid_Val = CASE 
    WHEN #TMP.webid IS NULL then 'NOT COMPLIANT'
    ELSE 'COMPLIANT'
END
FROM #TMP
