使用 UNION 從 SELECT 查詢中插入數據

Question

我正在下面寫一個查詢，

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

我想插入如下所示

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?
