SQL DB2 SQL错误不正确的语法

Question

What am I missing in this code below that will cause the error:

Msg 170, level 15, line 113 line 113: Incorrect syntax near 'actual_completion_date'.

update #Loss_mit_step
set
 [STEP924_COMPL_DATE] = Case when step_code ='924' then ls_actual_completion_date else ' ' end,
 [STEP926_COMPL_DATE] = Case when step_code ='926' then ls_actual_completion_date else ' ' end,
 [STEP927_COMPL_DATE] = Case when step_code ='927' then ls_actual_completion_date else ' ' end,
 [STEP928_COMPL_DATE] = Case when step_code ='928' then ls_actual_completion_date else ' ' end,
 [APPROVAL_DATE] = Case when step_code ='Q28' then ls_actual_completion_date else ' ' end

Answer 1

You appear to have an extra comma in the statement, at the very end.

I suggest you comment out each of the "case" lines, one by one, until you find out what the problem is, or until you only have one line left.

Answer 2

What you posted is syntactically correct, so you cannot get a syntax error. It actually parses fine. Your error message mentions actual_completion_date but you have no such token in your post. So obviously you posted an error from a different T-SQL.

Answer 3

我发现了错误的原因：在第一行的Actual_completion_date前面有一个空格。
