Question

我想加入两个临时表。

以下是我的表格：

CREATE TABLE #Result ( Process varchar(50), SuccessCount int, FailureCount int)
CREATE TABLE #SuccessResult ( Process varchar(50), SuccessCount int)
CREATE TABLE #FailureResult ( Process varchar(50), FailureCount int)

我的表中有一些数据，这是我的查询：

INSERT INTO #Result (Process, SuccessCount, FailureCount)
SELECT s.Process,s.SuccessCount,f.FailureCount
FROM #SuccessResult s, #FailureResult as f
INNER JOIN #SuccessResult on f.Process = #SuccessResult.Process

我收到了这个错误：

无法找到多部分标识符f.Process

我正在使用Microsoft SQL Server 2008。

我做错了什么？

Answer 1

尝试这种方式：

INSERT INTO #Result (Process, SuccessCount, FailureCount)
SELECT s.Process,s.SuccessCount,f.FailureCount
FROM #SuccessResult s 
INNER JOIN #FailureResult f on f.Process = #SuccessResult.Process

Answer 2

这是INSERT INTO ... SELECT ...的正确语法：

INSERT INTO #Result (Process, SuccessCount, FailureCount)
SELECT s.Process, s.SuccessCount, f.FailureCount
FROM #FailureResult as f
INNER JOIN #SuccessResult s on f.Process = s.Process

Answer 3

取出隐式联接。

INSERT INTO #Result (Process, SuccessCount, FailureCount)
SELECT s.Process,s.SuccessCount,f.FailureCount
FROM #SuccessResult s
INNER JOIN #FailureResult f on f.Process = s.Process
