sqlite是否在DELETE子句中支持JOIN？

Question

通常，MySQL支持JOIN子句进行删除查询。 范例- 删除w 从WorkRecord2 w 内部加入员工e   ON EmployeeRun =员工编号 WHERE Company ='1'AND Date ='2013-05-06'

sqlite支持吗？

Answer 1

SQLite不支持MySQL的联接结构。但是，您仍然可以使用相关子查询来重新定义您的查询，例如

DELETE
FROM WorkRecord2 w
WHERE EXISTS (SELECT 1 FROM Employee e
              WHERE w.EmployeeRun = e.EmployeeNo AND e.Company = '1') AND
    Date = '2013-05-06';
