我知道了,但我不知道怎么把它们搭配起来:
在两行之间选择:
SELECT
MAX(`VID`)-3 AS max1,
MAX(`VID`)-2 AS max2
FROM `tests`
GROUP BY `SID`
返回行的值:
SELECT *
FROM `tests`
WHERE `VID`>='max1' AND `VID`<='max2'
ORDER BY `SID` ASC, `VID` ASC
结果应该是这样的:
**Group:1**
test - 3
test - 4
**Group:2**
test - 283
test - 284
**Group:3**
test - 197
test - 198
**Group:4**
test - 173
test - 174
**Group:5**
test - 117
test - 118
**Group:6**
test - 162
test - 163
**Group:7**
test - 203
test - 204
**Group:8**
test - 72
test - 73
**Group:9**
test - 126
test - 127
**Group:10**
test - 106
test - 107
