Question

I try to get all table names for all databases.
But GetSchema(“Tables”) returns names only for one db.
It’s strange cause I use no restrictions and have dbowner on many dbs with read/write permissions.

What do I need to get all tables info?

I made it this way:

Cursor.Current = Cursors.WaitCursor;
                            sqlConnection.Open();
                            System.Data.DataTable dataTable = sqlConnection.GetSchema("Databases");

                            foreach (System.Data.DataRow row in dataTable.Rows)
                            {
                                using (var tablesConnection = new System.Data.SqlClient.SqlConnection())
                                {
                                    var dbName = row[0] as string;
                                    try
                                    {
                                        sqlConnection.ChangeDatabase(dbName);
                                    }
                                    catch (Exception)
                                    {
                                        continue;
                                    }

                                    var tables = sqlConnection.GetSchema("Tables");
                            }

The real issue is that even initial catalog is not specified explicitly default db is assigned. So GetSchema(“Tables”) shoul be called for every db on the server.
It may be other db, not necessarily ‘master’.
And I thought GetSchema(“Tables”) returns all tables for all databases.
