How do I list all the queries in a MS Access file using OleDB in C#?

Question

I have an Access 2003 file that contains 200 queries, and I want to print out their representation in SQL. I can use Design View to look at each query and cut and paste it to a file, but that's tedious. Also, I may have to do this again on other Access files, so I definitely want to write a program to do it.

Where are queries stored an Access db? I can't find anything saying how to get at them. I'm unfamiliar with Access, so I'd appreciate any pointers. Thanks!

Answer 1

Procedures are what you're looking for:

OleDbConnection conn = new OleDbConnection(connectionString);
conn.Open();

DataTable queries = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Procedures, null);

conn.Close();

This will give you a DataTable with the following columns in it (among others):

PROCEDURE_NAME: Name of the query

PROCEDURE_DEFINITION: SQL definition

So you can loop through the table like so:

foreach(DataRow row in queries.Rows)
{
    // Do what you want with the values here
    queryName = row["PROCEDURE_NAME"].ToString();
    sql = row["PROCEDURE_DEFINITION"].ToString();
}

Answer 2

you can put this together using the OleDbConnection's GetSchema method along with what Remou posted with regards to the ADO Schemas

Answer 3

In case you wanted to do a quick query by hand.

SELECT MSysObjects.Name
FROM MSysObjects
WHERE type = 5

Answer 4

Not in C#, but may be a good place to start:
