Experts,

As a background, I'm fairly new (or obsolete) on DB development. I'm using C# to build an application that would extract the list stored procedures found in a particular DB (SQL Sever 2K5). The question is, how do I do it programatically? and by doing so, will I be able to see the whole stored procedure, names and paramenters, or only names?
Thanks

to select the names of stored procedures in a particular database, use the following sql:

select name from sysobjects where type='P'

to select only user-defined stored procedures, use

select name from sysobjects where type='P' and category=0

There are a few ways that may work to perform this task, and, depending on which way you use, you may be able to get parameter information.  One of the easiest method to get both the stored procedures and the parameters would be to use the query provided by YZlat above.  Then, using the information in that query, you can use an ADO command object, set it up to access each individual stored procedure, then use a Parameters.Refresh action to load the parameters into the .Parameters collection.  Spin through the collection, and you have all of the parameters (and their in/out status)

oh, and to retrieve the text of the stored procedure, use

SELECT text    
FROM syscomments    
WHERE id = (SELECT id FROM sysobjects WHERE name = 'YOUR STORED PROC NAME HERE')    
ORDER BY colid

copy those 2 functions to your code:

public static SqlConnection GetConnection(string strConn)
            {
                  SqlConnection conn=null;
                  try
                  {
                        conn = new SqlConnection(strConn);
                        conn.Open();
                  }
                  catch (SqlException ex)
                  {
                        Console.Write("SQL ERROR: " + ex.Message);
                  }
                  catch (Exception ex)
                  {
                        Console.Write("ERROR: " + ex.Message);
                  }
                  return conn;
            }

            public static DataSet GetDataSet(string strConn, string query)
            {
                  SqlConnection conn=null;

                  DataSet dset = new DataSet();
                  try
                  {
                        conn = GetConnection(strConn);
                        SqlDataAdapter da = new SqlDataAdapter(query, conn);
                        da.SelectCommand.CommandTimeout = 0;
                        da.Fill(dset);
                  }
                  catch (SqlException ex)
                  {
                        Console.Write("SQL ERROR: " + ex.Message);
                  }
                  catch (Exception ex)
                  {
                        Console.Write("ERROR: " + ex.Message);
                  }
                  finally
                  {
                        if (conn.State == ConnectionState.Open)
                        {
                              conn.Close();
                        }
                  }
                  return dset;
            }


then call GetDataSet:

DataSet ds=new DataSet();
string query="select name from sysobjects where type='P' and category=0";
string strConn="YOUR DATABASE CONNECTION STRING HERE";
ds=GetDataSet(strConn,query);

if (ds.Tables.Count > 0)
{
      if(ds.Tables[0].Rows.Count > 0)
      {
            for(int i=0; i<=ds.Tables[0].Rows.Count -1;i++)
            {
                  string proc_name=ds.Tables[0].Rows[i].ItemArray[0].ToString();
                  //here get stored proc text using procedure name
                  string sql="SELECT text FROM syscomments WHERE id=(SELECT id FROM sysobjects WHERE name = '" + proc_name +"')";
                  DataSet ds2=new DataSet();
                  ds2=GetDataSet(strConn, sql);

                  //your code here
            }//end for
      }//end if
}//end if

You can also use SQLDMO.

Here is an example in .ASP

OK,

code works perfectly, however I'm unable to follow bhess1 recommendation to obtain the list of parameters. I have the code shown below, but I'm unable to call a refresh or update or whatever method would allow me to obtaint the parameters for the stored procedure:

SqlConnection tempConnection=GetConnection(strConn);
SqlCommand adoCmd = new SqlCommand(proc_name, tempConnection);
adoCmd.CommandType = CommandType.StoredProcedure;

Open in new window

Try adding this instead - it has changed in .Net, and it took me a bit of tracking to find the new syntax

SqlCommandBuilder.DeriveParameters(adoCmd);

This should populate the .Parameters collection of the SqlCommand object
