You are qmysql using your Twitter account. What am I doing wrong? Some drivers do not support qmysql cursors.

In that case, only queries in forwardOnly mode can be used successfully. With Microsoft SQL Server the result set returned by a stored procedure that uses the qmysql statement, or returns multiple result sets, will be accessible only if you set the query's forward only mode to forward using QSqlQuery::setForwardOnly.

SQL Database Drivers

On Windows NT qmysql systems, this is the default. It is recommended that you use unixODBC. So for example, a SQL query such qmysql.

If the table or field name is not quoted when created, the actual table name or field name will be lower-case. When QSqlDatabase::record or QSqlDatabase::primaryIndex access a table or field that was unquoted when created, the name passed to the function must be lower-case to ensure it is found. If the plugin is built with an older version, then forward-only mode will not be available - calling QSqlQuery::setForwardOnly with true will have no effect. While navigating the results in forward-only mode, the handle of QSqlResult may change. Run configure -help to see what drivers can be built. You should get an output similar to this:. The configure script cannot detect the neccessary libraries and include files if they are not in the standard paths, so it may be necessary to specify these paths using the -I and -L command-line options.

On Windows the -I parameter doesn't accept spaces in filenames, so use the 8. Look at the sections that follow for additional information about required libraries.

Please refer to the SQLite documentation and change logs for information about file format compatibility between versions.


Patch releases are therefore both backward and forward compatible. To force SQLite to use a specific file format, it is necessary to build and ship your own qmysql plugin with your own SQLite library as illustrated above. The database file must exist before a connection can be established. I have watched the video, but I did not qmysql yet.

I have run the maintenance tool, and added QT5. Giving up. I am trying to follow the instructions here, but I'm not successful yet. Configure reports MySql Qmysql you are looking for information about Qt related issue — register and post your question.


I will make sure to distribute this link to others that I know are having the same trouble. I was not including my qmysql "lib" in my qmysql variables.
