Detailed Description

The QSqlRecord class encapsulates a database record.

sql

The QSqlRecord class encapsulates the functionality and characteristics of a database record (usually a row in a table or view within the database). QSqlRecord supports adding and removing fields as well as setting and retrieving field values.

The values of a record's fields' can be set by name or position with setValue(); if you want to set a field to null use setNull(). To find the position of a field by name use indexOf(), and to find the name of a field at a particular position use fieldName(). Use field() to retrieve a QSqlField object for a given field. Use contains() to see if the record contains a particular field name.

When queries are generated to be executed on the database only those fields for which isGenerated() is true are included in the generated SQL.

A record can have fields added with append() or insert(), replaced with replace(), and removed with remove(). All the fields can be removed with clear(). The number of fields is given by count(); all their values can be cleared (to null) using clearValues().
