sql - INTO 列表中声明的变量数量必须与所选列的数量相匹配

Question

我已经检查了好几次。列计数匹配但我不断收到错误消息，说 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

错误：Cursorfetch：INTO 列表中声明的变量数量必须与所选列的数量匹配。

Answer 1

如果您在列之前或之后的逗号位置保持一致，您可能已经发现了这一点：

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

这是在说SELECT ... RangeLow, RangeHigh AS PostCode1, PostCode2 ...
