使用内连接，左外连接，交叉应用获取语法错误与Where子句

Question

我们有第三方数据库。联系信息包含在许多表中：contact1，contact2，contsupp。使用内连接，左外连接，交叉应用获取语法错误与Where子句。查询在没有左外连接的情况下工作。但我需要选择正确的电子邮件。在这种情况下，where子句应该放在哪里？

            OR (i.Key1 = '50-DEP')
            OR (i.Key1 = '51-RET')

Answer 1

可能语法错误在这行代码中：

LEFT outer join GoldMine_test.dbo.CONTSUPP cs on (  (cs.ACCOUNTNO = i.ACCOUNTNO) 

尝试用这个替换它：

LEFT outer join GoldMine_test.dbo.CONTSUPP cs on (cs.ACCOUNTNO = i.ACCOUNTNO) 

并检查它是否有效
