SQL Query将值从一个表插入另一个表

Question

我有一个2表结构:

表A:

RID; Name; LP
E    F     1
E    F     2
E    F     3
E    F     12
E    F     152

表B:

LP
1
2
3
12
152
...
156
157
180
itd.

查询类似于:

Insert into TableA(RID, Name, LP) Values ('E', 'F', Select LP from TableB)

我想要实现:

RID; Name; LP
E    F     1
E    F     2
E    F     3
E    F     12
E    F     152
E    F     156
E    F     157
E    F     180
etc.

Answer 1

你很亲密 尝试

INSERT INTO TableA(RID, Name, LP)
SELECT 'E', 'F', LP FROM TableB
-- Omit this where clause, if duplicate LP's are OK
WHERE TableB.LP NOT IN (SELECT LP FROM TableA)
