INTO列表中声明的变量数必须与所选列的变量数相匹配

Question

我已经多次检查了这个.列数匹配但我一直收到错误,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必须与所选列的变量数匹配.

Answer 1

如果您在列之前或之后的逗号位置一致,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

这是说 SELECT ... RangeLow, RangeHigh AS PostCode1, PostCode2 ...
