98 \class QSqlField -

99 \brief The QSqlField class manipulates the fields in SQL database tables -

100 and views. -

101 -

102 \ingroup database -

103 \ingroup shared -

104 \inmodule QtSql -

105 -

106 QSqlField represents the characteristics of a single column in a -

107 database table or view, such as the data type and column name. A -

108 field also contains the value of the database column, which can be -

109 viewed or changed. -

110 -

111 Field data values are stored as QVariants. Using an incompatible -

112 type is not permitted. For example: -

113 -

114 \snippet sqldatabase/sqldatabase.cpp 2 -

115 -

116 However, the field will attempt to cast certain data types to the -

117 field data type where possible: -

118 -

119 \snippet sqldatabase/sqldatabase.cpp 3 -

120 -

121 QSqlField objects are rarely created explicitly in application -

122 code. They are usually accessed indirectly through \l{QSqlRecord}s -

123 that already contain a list of fields. For example: -

124 -

125 \snippet sqldatabase/sqldatabase.cpp 4 -

126 \dots -

127 \snippet sqldatabase/sqldatabase.cpp 5 -

128 \snippet sqldatabase/sqldatabase.cpp 6 -

129 -

130 A QSqlField object can provide some meta-data about the field, for -

131 example, its name(), variant type(), length(), precision(), -

132 defaultValue(), typeID(), and its requiredStatus(), -

133 isGenerated() and isReadOnly(). The field's data can be -

134 checked to see if it isNull(), and its value() retrieved. When -

135 editing the data can be set with setValue() or set to NULL with -

136 clear(). -

149 optional. -
