SSIS - how to capture PRINT message? - sql-server

Question

The Execute SQL task calls a procedure that has a PRINT command inside. How can I display these messages at once in the progress tab (or in output)?

Answer 1

You will need to write your own process for invoking SQL as the Execute SQL Task does not have the event handler defined for the side channel communication.
I would go at it from a Script Task
Setup
In my database, I have a stored procedure defined as the following
CREATE OR ALTER PROCEDURE dbo.Printsalot
AS
BEGIN
SET NOCOUNT ON;
RAISERROR('This is the first message', 10, 1) WITH NOWAIT;
WAITFOR DELAY '00:00:05';
RAISERROR('This is the second message', 10, 1) WITH NOWAIT;
WAITFOR DELAY '00:00:04';
RAISERROR('This is the third message', 10, 1) WITH NOWAIT;
WAITFOR DELAY '00:00:03';
RAISERROR('This is the fourth message', 10, 1) WITH NOWAIT;
WAITFOR DELAY '00:00:02';
RAISERROR('This is the fifth message', 10, 1) WITH NOWAIT;
WAITFOR DELAY '00:00:01';
RAISERROR('This is the sixth message', 10, 1) WITH NOWAIT;
END;
I use RAISERROR instead of print so I can WITH NOWAIT otherwise, the PRINT isn't going to be so useful. And I put delays in there to simulate a longer running process.
Script Task
Your TODO with the following code
Define connString appropriately. I've never had much luck tying into the existing connection managers in a script task so I typically use a C# variable to hold the connection string info and pass that into the script
Define a CommandTimeout on your command object if the proc takes too long
Define proc appropriately
And code
using System;
using System.Data;
using System.Data.SqlClient;
using Microsoft.SqlServer.Dts.Runtime;
using System.Windows.Forms;
namespace ST_ExecuteSQLWithInfo
{
[Microsoft.SqlServer.Dts.Tasks.ScriptTask.SSISScriptTaskEntryPointAttribute]
public partial class ScriptMain : Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase
{
public void Main()
{
// TODO: Fix this
string connString = #"SERVER=.\dev2017;Integrated Security=true;DATABASE=tempdb";
// TODO: Fix this
string proc = "dbo.Printsalot";
using (SqlConnection connection = new SqlConnection(connString))
{
connection.Open();
connection.FireInfoMessageEventOnUserErrors = true;
connection.InfoMessage += new SqlInfoMessageEventHandler(HandleSqlProgress);
using (SqlCommand command = new SqlCommand(proc, connection))
{
command.CommandType = CommandType.StoredProcedure;
// TODO: Define a command.CommandTimeout value
command.ExecuteNonQuery();
}
}
Dts.TaskResult = (int)ScriptResults.Success;
}
public void HandleSqlProgress(object sender, SqlInfoMessageEventArgs e)
{
bool fireAgain = true;
Dts.Events.FireInformation(0, "SQL Progress", e.Message, "", 0, ref fireAgain);
}
enum ScriptResults
{
Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success,
Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
};
}
}
Results
From the output window/Progress window
