Definition qobject.h:103
The QSqlDriver class is an abstract base class for accessing specific SQL databases.
Definition qsqldriver.h:26
virtual QString formatValue(const QSqlField &field, bool trimStrings=false) const
Returns a string representation of the field value for the database.
virtual bool commitTransaction()
This function is called to commit a transaction.
IdentifierType
This enum contains a list of SQL identifier types.
Definition qsqldriver.h:41
virtual QSqlResult * createResult() const =0
Creates an empty SQL result on the database.
virtual QSqlIndex primaryIndex(const QString &tableName) const
Returns the primary index for table tableName.
virtual bool beginTransaction()
This function is called to begin a transaction.
virtual QSqlRecord record(const QString &tableName) const
Returns a QSqlRecord populated with the names of the fields in table tableName.
DriverFeature
This enum contains a list of features a driver might support.
Definition qsqldriver.h:33
virtual bool rollbackTransaction()
This function is called to rollback a transaction.
virtual void close()=0
Derived classes must reimplement this pure virtual function in order to close the database connection...
virtual QString escapeIdentifier(const QString &identifier, IdentifierType type) const
Returns the identifier escaped according to the database rules.
virtual QVariant handle() const
Returns the low-level database handle wrapped in a QVariant or an invalid variant if there is no hand...
virtual bool open(const QString &db, const QString &user=QString(), const QString &password=QString(), const QString &host=QString(), int port=-1, const QString &connOpts=QString())=0
Derived classes must reimplement this pure virtual function to open a database connection on database...
virtual bool isIdentifierEscaped(const QString &identifier, IdentifierType type) const
Returns whether identifier is escaped according to the database rules.
virtual bool hasFeature(DriverFeature f) const =0
Returns true if the driver supports feature feature; otherwise returns false.
virtual QStringList tables(QSql::TableType tableType) const
Returns a list of the names of the tables in the database.
The QSqlField class manipulates the fields in SQL database tables and views.
Definition qsqlfield.h:19
The QSqlIndex class provides functions to manipulate and describe database indexes.
Definition qsqlindex.h:18
The QSqlRecord class encapsulates a database record.
Definition qsqlrecord.h:20
The QSqlResult class provides an abstract interface for accessing data from specific SQL databases.
