sql - 如何使用 SQL Server 在变量中创建 Insert with Select 查询

Question

如何使用 SQL Server 在变量中创建带有选择查询的插入？

例如:

DECLARE @sqlCommand nvarchar(MAX)
DECLARE @odbname varchar(30)
DECLARE @m VARCHAR(20)
DECLARE @id VARCHAR(20)
DECLARE @br VARCHAR(30)
DECLARE @ndbname VARCHAR(30)

SET @ndbname='databasename'
SET @id = 2

SET @odbname = 'olddatabasename'
SET @br = 2

SET @m = 9

DECLARE @insert VARCHAR(MAX)
SET @insert = 'INSERT INTO'+ @ndbname+'.[pm]([pmId],[pmCode],[pmName])'  

EXEC (@insert)

SET @sqlCommand = 'SELECT @id AS spID,[spCode],[spName] `enter code here`FROM' + @0dbname+'.[sp] where spbID = @br and spID = @m'

EXECUTE sp_executesql @sqlCommand, N'@br nvarchar(75),@m nvarchar(75),@id VARCHAR(20)',@br = @br,@m=@m,@id=@id

实际上我需要在插入查询中执行一个选择查询，即将选定的数据插入到另一个数据库表中

SET @insert='INSERT INTO'+ @ndbname+'.[pm]([pmId],[pmCode],[pmName])'  
SET @sqlCommand = @insert + ' ' +'SELECT @id AS spID,[spCode],[spName] `enter code here`FROM' + @0dbname+'.[sp] where spbID = @br and spID = @m'
EXECUTE sp_executesql @sqlCommand, N'@br nvarchar(75),@m nvarchar(75),@id VARCHAR(20)',@br = @br,@m=@m,@id=@id
