如何将动态openquery下面的结果插入到现有表

中

  DECLARE @TSQL varchar(8000), @VAR char(2)
  SELECT  @VAR = 'CA'
  SELECT  @TSQL = 'SELECT * FROM OPENQUERY(MyLinkedServer,''SELECT * FROM pubs.dbo.authors WHERE state = ''''' + @VAR + ''''''')'
  EXEC (@TSQL)

我尝试插入但没有工作。

    INSERT INTO TableA 
    SELECT *
    FROM (EXEC (@TSQL))

Answer 1

你非常接近

DECLARE @TSQL varchar(8000), @VAR char(2)
SELECT  @VAR = 'CA'
SELECT  @TSQL = 'SELECT * FROM OPENQUERY(MyLinkedServer,''SELECT * FROM pubs.dbo.authors WHERE state = ''''' + @VAR + ''''''')'

INSERT INTO TableA
EXEC (@TSQL)

Answer 2

您可以在动态字符串中执行所有操作以避免INSERT EXEC语句

DECLARE @TSQL varchar(8000), @VAR char(2)
SELECT  @VAR = 'CA'
SELECT  @TSQL = 'INSERT INTO TableA SELECT * FROM OPENQUERY(MyLinkedServer,''SELECT * FROM pubs.dbo.authors WHERE state = ''''' + @VAR + ''''''')'

EXEC (@TSQL)
