And a stored procedure in SQL, like this:
和SQL中的存储过程,如下所示:
CREATE PROCEDRE dbo.prcTest
@XDataTable dbo.typTable1 READONLY
AS
BEGIN
.
.
.

现在问题!!! :当我在delphi中发送一个表作为参数时,如下所示:

I am thinking something like that:
我在想这样的事情:
Set the DataType = ftObject;
Set datatypename = <your_procedureName>.<your_parameter>
With FireDACStoredProcedure.Params.ParamByName('@XDataTable') do
begin
DataType := ftObject;
DataTypeName := 'prcTest.@XDataTable';
end;
