  • What's the quickest way to dump & load a MySQL InnoDB database using mysqldump?

    - by Josh Schwartzman
    I would like to create a copy of a database with approximately 40 InnoDB tables and around 1.5GB of data with mysqldump and MySQL 5.1. What are the best parameters (ie: --single-transaction) that will result in the quickest dump and load of the data? As well, when loading the data into the second DB, is it quicker to: 1) pipe the results directly to the second MySQL server instance and use the --compress option or 2) load it from a text file (ie: mysql < my_sql_dump.sql)

  • Capture Stored Procedure print output in .NET (Different model!)

    - by Workshop Alex
    Basically, this question with a difference... Is it possible to capture print output from a TSQL stored procedure in .NET, using the Entity Framework? The solution in the other question doesn't work for me. It works with the connection type from System.Data.SqlClient but I'm using the one from System.Data.EntityClient which does not have an InfoMessage event. (Of course, I could just create an SQL connection based on the Entity connection settings, but prefer to do it directly.)
