104 \class QSqlQueryModel -

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

106 result sets. -

107 -

108 \ingroup database -

109 \inmodule QtSql -

110 -

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

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

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

114 view classes such as QTableView. For example: -

115 -

116 \snippet sqldatabase/sqldatabase.cpp 16 -

117 -

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

119 the view header. -

120 -

121 QSqlQueryModel can also be used to access a database -

122 programmatically, without binding it to a view: -

123 -

124 \snippet sqldatabase/sqldatabase.cpp 21 -

125 -

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

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

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

129 -

130 \snippet sqldatabase/sqldatabase.cpp 22 -

131 -

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

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

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

135 model based on a single database table. -

136 -

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

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

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

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

141 read-write model based on QSqlQueryModel. -

142 -

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

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

145 See fetchMore() for more information. -
