Passing user defined table parameter to dynamic sql, sp_executesql

I need help with passing my "user defined table type" parameter to dynamic sql, sp_executesql.

Here's my sample code:

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

It says : Must declare the table variable "@IdTable"

I can't get this to work, and can't get a workaround with coalesce (for bigints) either because the result will be more than 8000 characters.

Solution

  • Try setting @ParamDefs to:

    EXEC sp_executesql @str , N'@IdTable ListBigintType readonly', @IdTable = @IDLIST

    Here's a full working example:

    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
