92 \class QSqlField -

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

94 and views. -

95 -

96 \ingroup database -

97 \ingroup shared -

98 \inmodule QtSql -

99 -

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

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

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

103 viewed or changed. -

104 -

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

106 type is not permitted. For example: -

107 -

108 \snippet sqldatabase/sqldatabase.cpp 2 -

109 -

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

111 field data type where possible: -

112 -

113 \snippet sqldatabase/sqldatabase.cpp 3 -

114 -

115 QSqlField objects are rarely created explicitly in application -

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

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

118 -

119 \snippet sqldatabase/sqldatabase.cpp 4 -

120 \dots -

121 \snippet sqldatabase/sqldatabase.cpp 5 -

122 \snippet sqldatabase/sqldatabase.cpp 6 -

123 -

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

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

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

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

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

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

130 clear(). -

131 -

134 -

135 /*! -

136 \enum QSqlField::RequiredStatus -

142 \value Unknown The database driver couldn't determine whether the field is required or -

143 optional. -
