第一个是正确的，除非您想要自连接呈指数爆炸式增长。

第一个

JOINS 必须位于 WHERE 子句之前，

尽管您可以使用 EXISTS 重写 JOINS，然后将其放入 WHERE 子句中

第一个查询是正确的，第二个查询会给出，嗯....很多结果。

为了回应您的评论，正如 SQLMenace 指出的那样，如果您想匹配 任何条件：

SELECT ID, STATUS, ITEM_TYPE,CREATED_TIME,UPDATED_TIME
WHERE STATUS IN('OPEN','UPDATED')
   OR ITEM_TYPE IN ('ITEM1','ITEM2')
   OR CREATED_TIME BETWEEN 'XX' AND 'YY'
   OR UPDATED_TIME BETWEEN 'XX' AND 'ZZ'

或者，如果您想始终限制时间，但满足第一个条件中的任一，则使用换行的 OR：

SELECT ID, STATUS, ITEM_TYPE,CREATED_TIME,UPDATED_TIME
WHERE (STATUS IN('OPEN','UPDATED') OR ITEM_TYPE IN ('ITEM1','ITEM2'))
  AND CREATED_TIME BETWEEN 'XX' AND 'YY'
  AND UPDATED_TIME BETWEEN 'XX' AND 'ZZ'

The first query is correct, the second would give, well....a LOT of reuslts.

In response to your comment, as SQLMenace pointed out, use OR instead if you want to match any of the conditions:

SELECT ID, STATUS, ITEM_TYPE,CREATED_TIME,UPDATED_TIME
WHERE STATUS IN('OPEN','UPDATED')
   OR ITEM_TYPE IN ('ITEM1','ITEM2')
   OR CREATED_TIME BETWEEN 'XX' AND 'YY'
   OR UPDATED_TIME BETWEEN 'XX' AND 'ZZ'

Or, if you wanted to always restrict on the time, but meet either of the first conditions, then use a wrapped OR:

SELECT ID, STATUS, ITEM_TYPE,CREATED_TIME,UPDATED_TIME
WHERE (STATUS IN('OPEN','UPDATED') OR ITEM_TYPE IN ('ITEM1','ITEM2'))
  AND CREATED_TIME BETWEEN 'XX' AND 'YY'
  AND UPDATED_TIME BETWEEN 'XX' AND 'ZZ'
