这种情况是不是要使用游标或有其他好办法么?
@a=200
table
ID SXI XXI
2 500 300
4 299 200
6 199 100
3 99 0
使用@a 去talbe检索 当@的值位于 SXI XXI之间时候
检索出ID出来
如 @a=200
则 检索出 4 299 200这条记录
检索出ID 4
该如何?CODE说话!
[解决办法]
select * from t where @a between xxi and sxi
[解决办法]
try:
CREATE TABLE #T([id] int,SXI int,XXI int)
INSERT INTO #T
SELECT 2 ,500 ,300 UNION ALL
SELECT 4 ,299 ,200 UNION ALL
SELECT 6 ,199 ,100 UNION ALL
SELECT 3 ,99 ,0
DECLARE @a int
SET @a=400
SELECT [id] FROM #T WHERE @a BETWEEN XXI AND SXI OR @a BETWEEN SXI AND XXI
DROP TABLE #T
