Question

这个问题已经有答案了:

Error on T-Sql in Cursor use (2 个回答)

已关闭 10 年前。

我已经检查过好几次了。列计数匹配，但我不断收到错误消息，指出 fetch into 语句与计数不匹配

declare cur_range CURSOR FOR
SELECT 
GroupID,
OddEven,
RangeLow,
RangeHigh
PostCode1,
PostCode2,
ID,
OldPrimaryID,
ThFareID
FROM tmpNewPrimaryRange;    

OPEN cur_range

FETCH NEXT FROM cur_range
into
 @cur_GroupID
 , @cur_OddEven
 , @cur_RangeLow
 , @cur_RangeHigh
 , @cur_PostCode1
 , @cur_PostCode2
 , @cur_ID
 , @cur_OldPrimaryID
 , @cur_ThFareID

Error: Cursorfetch: The number of variables declared in the INTO list must match that of selected columns.

Answer 1

如果您在列之前或之后一致地放置逗号，您可能会发现这一点:

declare cur_range CURSOR FOR
SELECT 
GroupID,
OddEven,
RangeLow,
RangeHigh    --- <-- ******* NO COMMA HERE ******
PostCode1,
PostCode2,
ID,
OldPrimaryID,
ThFareID

这就是说SELECT ... RangeLow, RangeHigh AS PostCode1, PostCode2 ...
