Some drivers don't support scrollable cursors. Note that if the text encoding set when connecting to the database is not the same as in the database, problems with transliteration might arise. An application with write database security policy can write to database. For more information about PostgreSQL visit http: SQLite operates on a single file, which must be set as the database name when opening a connection.

Note that the driver only supports the UTF-8 encoding. QSqlDriver is responsible for connecting to a database, establish the proper environment, etc.
Ensure that the plugin drlver in the correct directory. Install the appropriate PostgreSQL developer libraries for your compiler. If you cannot get a source distibution to compile the client libraries yourself, you must make sure that the pre-compiled library is compatible with your compiler, otherwise you will get a lot of "undefined symbols" errors.

QSqlDatabase forwards many of its function calls directly to QSqlDriver which provides the concrete implementation. When qibse all mentioned settings in the connection string and not by the functions set…I discovered that they were not assigned to the database object.
LIB to build the plugin:. SQLite has some restrictions regarding multiple users and multiple transactions. Look at the sections that follow for additional information about required libraries. Usually, this means that the database server will use the user authentication provided by the operating system instead of its own authentication mechanism.
Read How to Create Qt Plugins for more information on this. The specific name is not important qqibase it is stored together with the project, and so the other developer can not to build the project in a proper way because of the error "No such QT version is found on this machine" or something like this.
CopperSpice Overview: QIBASE
An application with read database security policy can read from database. 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.
Leave the username and password empty when opening a connection with QSqlDatabase to use the external credentials authentication.
The container can contain: Troubleshooting You should always use client libraries that have been compiled with the same compiler as you are using for your project. The DB2 header and include files should already be installed in the right directories. Unicode support was introduced in PostgreSQL version xriver. If you are expecting a debug version to be built as well, don't use the "-o Makefile" option.
On Windows, you can use Visual Studio's dependency walker. Download the following components: Most installation programs also allow you to install "development libraries", and these are what you need. Login, password and full path to the database could be passed in the connection string, but there I faced with the following problem.
Patch releases are therefore both backward and forward compatible. When a database is added see QSqlDatabase:: SQLite also supports in-memory databases, simply pass ": SQLite qbiase some restrictions regarding multiple users and qibasee transactions.

The DB2 header and include files should already be installed in the right directories. Install the appropriate PostgreSQL developer libraries for your compiler. When a database is added see QSqlDatabase:: You should get an output similar to this:. For Unix systems there are some implementations which must be installed first.
