  • Installer package for program that uses JDBC to connect to MySQL....

    - by eli1987
    I have an installer wizard thing called 'install creator'. I want to include my mySQL database into the installer or find another way that the user, upon installation, can just use my database. Prob is-not everyone has MySQL installed on the computer and even then, the user doesn't know the name of the database or my password. Somehow the database must be created automatically upon install, and for my purposes, some of the tables created. How can one do this. Thanks

    I am running some sample tests against mysql, and finding that there are a bunch of queries which are stuck in "copying to tmp tables". They remain stuck in the same state.

    I have a table created long ago in postgreSQL. Now i want to look at the sql statement used to create it but cannot figure it out.

  • Generate XSD from 2005 SQL Server Database

    - by Robert Finlayson
    What is the easiest method to generate an XSD schema from a 2005 SQL Server Database? Would it be possible to generate one XSD schema for the entire Database (~100 tables)? I searched online and found a SQL example that generates one XSD for the one table: DECLARE @schema xml SET @schema = (SELECT * FROM MyTableName FOR XML AUTO, ELEMENTS, XMLSCHEMA('MyTableNameSchema')) SELECT @schema Outside of SQL Server, is there a third party tool that could generate the XSD file from the 2005 Database?

  • MSSQL using SSH-tunnel from Visual Studio

    - by pbt
    Hi, I recently contacted a web host regarding support for external database access to a Microsoft SQL Database included in a package they offer. They replied saying that it is only possible with an SSH-tunnel. Is it possible to connect to a MS SQL database in Visual Studio using an SSH-tunnel? It is important for me to be able to access the database from my local machine (for debugging, generating LINQ classes, editing tables, etc). Or, how should I go about working with their database?

  • Can I optimize this at all?

    - by Moshe
    I'm working on an iOS app and I'm using the following code for one of my tables to return the number of rows in a particular section: return [[kSettings arrayForKey:@"views"] count]; Is there any other way to write that line of code so that it is more memory efficient? EDIT: kSettings = NSUserDefaults standardUserDefaults. Is there any way to rewrite my line of code so that whatever memory it occupies is released sooner than it is released now?

  • Determine Last Modification Datetime for an Azure Table

    - by embeddedprogrammer
    I am developing an application which may be hosted on a microsoft sql server, or on Azure SQL, depending upon the end user's wishes. My whole system works fine with the exception of some WCF functions which determine the last modification time of tables using the following technique: SELECT OBJECT_NAME(OBJECT_ID) as tableName, last_user_update as lastUpdate FROM mydb.sys.dm_db_index_usage_stats This query fails in Azure. Is there any analogous way to get table last modification dates from Azure's sql?
