Is there anyway to speed up SQL Server Management Objects traversal of a existing database?

.net, c#, smo, sql-server

Solution

Try to force SMO to read all the required fields at once, instead of querying on access. See this blog for more information

EDIT: Link is dead but I found the page on archive.org. Here's the relevant code:

Server server = new Server();

// Force IsSystemObject to be returned by default.
server.SetDefaultInitFields(typeof(StoredProcedure), "IsSystemObject");

StoredProcedureCollection storedProcedures = server.Databases["AdventureWorks"].StoredProcedures;

foreach (StoredProcedure sp in storedProcedures) {
    if (!sp.IsSystemObject) {
        // We only want user stored procedures
    }
}

Problem

I'm currently using SMO and C# to traverse databases to create a tree of settings representing various aspects of the two databases, then comparing these trees to see where and how they are different. The problem is, for 2 reasonably sized database, it takes almost 10mins to crawl them locally and collect table/column/stored procedure information I wish to compare. Is there a better interface then SMO to access databases in such a fashion? I would like to not include any additional dependencies, but I'll take that pain for a 50% speed improvement. Below is a sample of how I'm enumerating tables and columns. ``` Microsoft.SqlServer.Management.Smo.Database db = db_in; foreach (Table t in db.Tables) { if (t.IsSystemObject == false) { foreach (Column c in t.Columns) { } } } ```
