使用UNION从SELECT查询中插入数据

Question

我在下面写一个查询，

WITH muhammed AS(
    SELECT * FROM acct_db2016.dbo.acct_tran WHERE trc_acno='12008001'
    UNION
    SELECT * FROM acct_db.dbo.acct_tran WHERE trc_acno='12008001')
SELECT * FROM muhammed

我想插入如下给出的

INSERT INTO acct_db2016.dbo.acct_tran SELECT * FROM muhammed

怎么做？

Answer 1

WITH muhammed AS(
    SELECT * FROM acct_db2016.dbo.acct_tran WHERE trc_acno='12008001'
    UNION
    SELECT * FROM acct_db.dbo.acct_tran WHERE trc_acno='12008001'
)

INSERT INTO acct_db2016.dbo.acct_tran -- <-- put the insert at this line

SELECT * FROM muhammed -- <-- Why you are inserting duplicate data from the first table?
