我需要帮助将“用户定义的表类型”参数传递给动态sql,sp_executesql。
这是我的示例代码:
DECLARE @str as nvarchar(Max)
DECLARE @IDLIST AS ListBigintType /* this is my table type, with ItemId column (bigint)*/
INSERT INTO @IDLIST
SELECT DISTINCT bigintid FROM tableWithBigInts WITH(NOLOCK)
set @str ='select * from SomeTable where ID in (select ItemId from @IdTable) '
EXEC sp_executesql @str , @ParamDefs, @IdTable = @IDLIST
它说:必须声明表变量“@IdTable”
我无法使其工作,并且无法通过合并(对于bigints)获得解决方法,因为结果将超过8000个字符。

尝试将@ParamDefs
设置为:
EXEC sp_executesql @str , N'@IdTable ListBigintType readonly', @IdTable = @IDLIST
这是一个完整的工作示例:
create type ListBigintType as table (ItemId bigint)
go
declare @t as ListBigintType
insert @t select 6*7
exec sp_executesql
N'select ItemId from @IdTable',
N'@IdTable ListBigintType readonly', @t
