Answer 1

不确定您正在使用哪种语言，并且不确定您要查找的输出，但在C＃/ ADO.NET中，您可以通过执行以下操作来获取选择查询输出到DataSet中：

SqlConnection sqlConnection = new SqlConnection(
    "server=localhost\SQLEXPRESS;Integrated Security=SSPI;database=Northwind");

SqlDataAdapter sqlDataAdapter = new SqlDataAdapter("[MyStoredProc]", sqlConnection);
sqlDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure;

// Whatever selects your stored proc does will become tables in the DataSet
DataSet northwindDataSet = new DataSet("Northwind");

sqlConnection.Open();

sqlDataAdapter.Fill(northwindDataSet);

sqlConnection.Close();

// data now available in: dsNorthwind.Tables[0];, etc. depending on how many selects your query ran

假设您想在T-SQL中使用OUTPUT参数的值，您可以执行以下操作：

CREATE PROC pTestProc (@in int, @out int OUTPUT)
AS
    SET @Out = @In
    SELECT 'Done'
    RETURN 1
GO

DECLARE @Output INT
EXEC pTestProc  46, @Output OUTPUT
SELECT @Output
