98 \class QSqlQueryModel -

99 \brief The QSqlQueryModel class provides a read-only data model for SQL -

100 result sets. -

101 -

102 \ingroup database -

103 \inmodule QtSql -

104 -

105 QSqlQueryModel is a high-level interface for executing SQL -

106 statements and traversing the result set. It is built on top of -

107 the lower-level QSqlQuery and can be used to provide data to -

108 view classes such as QTableView. For example: -

109 -

110 \snippet sqldatabase/sqldatabase.cpp 16 -

111 -

112 We set the model's query, then we set up the labels displayed in -

113 the view header. -

114 -

115 QSqlQueryModel can also be used to access a database -

116 programmatically, without binding it to a view: -

117 -

118 \snippet sqldatabase/sqldatabase.cpp 21 -

119 -

120 The code snippet above extracts the \c salary field from record 4 in -

121 the result set of the query \c{SELECT * from employee}. Assuming -

122 that \c salary is column 2, we can rewrite the last line as follows: -

123 -

124 \snippet sqldatabase/sqldatabase.cpp 22 -

125 -

126 The model is read-only by default. To make it read-write, you -

127 must subclass it and reimplement setData() and flags(). Another -

128 option is to use QSqlTableModel, which provides a read-write -

129 model based on a single database table. -

130 -

131 The \l{querymodel} example illustrates how to use -

132 QSqlQueryModel to display the result of a query. It also shows -

133 how to subclass QSqlQueryModel to customize the contents of the -

134 data before showing it to the user, and how to create a -

135 read-write model based on QSqlQueryModel. -

136 -

137 If the database doesn't return the number of selected rows in -

138 a query, the model will fetch rows incrementally. -

139 See fetchMore() for more information. -
