  • Regression tests for T-SQL stored procedures

    - by Achim
    Hi, I would like to regression test t-sql stored procedures. My idea is to specify for each SP multiple input parameter sets. The SP should be executed with these parameters, results should be written to disc. Next time the new results should be compared with results stored before. Does anybody know a good tool for something like that?

  • In-Memory SQL-CE

    - by harley.333
    Is there a way to connect to a SQL-CE database as a stream? Specifically, our ASP.Net application builds small SDF at runtime for off-line needs.
