| \namespace QSql |
| \inmodule QtSql |
| \brief The QSql namespace contains miscellaneous identifiers used throughout |
| the Qt SQL module. |
| |
| \ingroup database |
| |
| |
| \sa {Qt SQL} |
| */ |
| |
| /*! |
| \enum QSql::Location |
| |
| This enum type describes special SQL navigation locations: |
| |
| \value BeforeFirstRow Before the first record. |
| \value AfterLastRow After the last record. |
| |
| \sa QSqlQuery::at() |
| */ |
| |
| /*! |
| \enum QSql::ParamTypeFlag |
| |
| This enum is used to specify the type of a bind parameter. |
| |
| \value In The bind parameter is used to put data into the database. |
| \value Out The bind parameter is used to receive data from the database. |
| \value InOut The bind parameter is used to put data into the |
| database; it will be overwritten with output data on executing |
| a query. |
| \value Binary This must be OR'd with one of the other flags if |
| you want to indicate that the data being transferred is |
| raw binary data. |
| */ |
| |
| /*! |
| \enum QSql::TableType |
| |
| This enum type describes types of SQL tables. |
| |
| \value Tables All the tables visible to the user. |
| \value SystemTables Internal tables used by the database. |
| \value Views All the views visible to the user. |
| \value AllTables All of the above. |
| */ |
| |
| /*! |
| \enum QSql::NumericalPrecisionPolicy |
| |
| Numerical values in a database can have precisions greater than their corresponding |
| C++ types. This enum lists the policies for representing such values in the application. |
| |
| \value LowPrecisionInt32 Force 32bit integer values. In case of floating point numbers, |
| the fractional part is silently discarded. |
| \value LowPrecisionInt64 Force 64bit integer values. In case of floating point numbers, |
| the fractional part is silently discarded. |
| \value LowPrecisionDouble Force \c double values. This is the default policy. |
| \value HighPrecision Strings will be used to preserve precision. |
| |
| Note: The actual behaviour if an overflow occurs is driver specific. The Oracle database |
| just returns an error in this case. |
