Before being able to create sqlbased datasets, you need to install the proper jdbc drivers for the database that you intend to connect to. The qtsql module uses driver plugins to communicate with the different database apis. Hi folks, i want to move my sqlite dbs to another location and wants to mount on nfs. Since qts sql module api is databaseindependent, all databasespecific code is contained within these drivers. The completeness of the support for other systems depends on the availability and quality of client libraries. Sqlite operates on a single file, which must be set as the database name when opening a connection. Well the problem is that the sqlite driver only automagically registers it once the driver class has been loaded. Several drivers are supplied with qt and other drivers can be added. Without that, the jvm doesnt know it even exists theres apparently a property for it somewhere, but as a plugin you cant set that property heck, even if you can, its probably easier to call class.
To load the sqlsrv driver when php is started, first move a driver file into your extension directory. Sqlite is the inprocess database system with the best test coverage and support on all platforms. Sqlite is an inprocess database, which means that it is not necessary to have a database server. I hope you have not moved the qt directory after qt build because it records some hard paths when building.
Odbc driver for sqlite databaseindependent layer that. Oracle via oci, postgresql, and mysql through either odbc or a native driver are welltested on windows and linux. If there already exists a database connection called connectionname, that connection is removed. Type a logical name to associate with the database file. If the file does not exist, sqlite will try to create it. The specify tables and columns dialog is displayed. If you start the application separately then you need to have subdirectory in your app folder named sqldrivers and there you need to have this qsqlite. Select the tables, views and columns you wish to import. If desired you can edit the sql statement directly, or load a previously saved sql file with a more complex sql statement. The database connection is referred to by connectionname.
