+.SH DESCRIPTION
+The QSqlRecord class encapsulates a database record, i.e. a set of database fields.
+.PP
+The QSqlRecord class encapsulates the functionality and characteristics of a database record (usually a table or view within the database). QSqlRecords support adding and removing fields as well as setting and retrieving field values.
+.PP
+QSqlRecord is implicitly shared. This means you can make copies of the record in time O(1). If multiple QSqlRecord instances share the same data and one is modifying the record's data then this modifying instance makes a copy and modifies its private copy - thus it does not affect other instances.
+.PP
+See also QSqlRecordInfo and Database Classes.
+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "QSqlRecord::QSqlRecord ()"
+Constructs an empty record.
+.SH "QSqlRecord::QSqlRecord ( const QSqlRecord & other )"
+Constructs a copy of \fIother\fR.
+.SH "QSqlRecord::~QSqlRecord ()\fC [virtual]\fR"
+Destroys the object and frees any allocated resources.
+.SH "void QSqlRecord::append ( const QSqlField & field )\fC [virtual]\fR"
+Append a copy of field \fIfield\fR to the end of the record.
+.PP
+Reimplemented in QSqlIndex.
+.SH "void QSqlRecord::clear ()\fC [virtual]\fR"
+Removes all the record's fields.
+.PP
+See also clearValues().
+.PP
+Reimplemented in QSqlCursor.
+.SH "void QSqlRecord::clearValues ( bool nullify = FALSE )\fC [virtual]\fR"
+Clears the value of all fields in the record. If \fInullify\fR is TRUE, (the default is FALSE), each field is set to NULL.
+.SH "bool QSqlRecord::contains ( const QString & name ) const"
+Returns TRUE if there is a field in the record called \fIname\fR; otherwise returns FALSE.
+.SH "uint QSqlRecord::count () const"
+Returns the number of fields in the record.
+.SH "QSqlField * QSqlRecord::field ( int i )"
+Returns the field at position \fIi\fR within the record, or 0 if it cannot be found.
+.SH "QSqlField * QSqlRecord::field ( const QString & name )"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Returns the field called \fIname\fR within the record, or 0 if it cannot be found. Field names are not case-sensitive.
+.SH "const QSqlField * QSqlRecord::field ( int i ) const"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.SH "const QSqlField * QSqlRecord::field ( const QString & name ) const"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Returns the field called \fIname\fR within the record, or 0 if it cannot be found. Field names are not case-sensitive.
+.SH "QString QSqlRecord::fieldName ( int i ) const"
+Returns the name of the field at position \fIi\fR. If the field does not exist, QString::null is returned.
+.SH "void QSqlRecord::insert ( int pos, const QSqlField & field )\fC [virtual]\fR"
+Insert a copy of \fIfield\fR at position \fIpos\fR. If a field already exists at \fIpos\fR, it is removed.
+.SH "bool QSqlRecord::isEmpty () const"
+Returns TRUE if there are no fields in the record; otherwise returns FALSE.
+.SH "bool QSqlRecord::isGenerated ( const QString & name ) const"
+Returns TRUE if the record has a field called \fIname\fR and this field is to be generated (the default); otherwise returns FALSE.
+.PP
+See also setGenerated().
+.SH "bool QSqlRecord::isGenerated ( int i ) const"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Returns TRUE if the record has a field at position \fIi\fR and this field is to be generated (the default); otherwise returns FALSE.
+.PP
+See also setGenerated().
+.SH "bool QSqlRecord::isNull ( const QString & name ) const"
+Returns TRUE if the field called \fIname\fR is NULL or if there is no field called \fIname\fR; otherwise returns FALSE.
+.PP
+See also position().
+.SH "bool QSqlRecord::isNull ( int i ) const"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Returns TRUE if the field \fIi\fR is NULL or if there is no field at position \fIi\fR; otherwise returns FALSE.
+.PP
+See also fieldName().
+.SH "QSqlRecord & QSqlRecord::operator= ( const QSqlRecord & other )"
+Sets the record equal to \fIother\fR.
+.SH "int QSqlRecord::position ( const QString & name ) const"
+Returns the position of the field called \fIname\fR within the record, or -1 if it cannot be found. Field names are not case-sensitive. If more than one field matches, the first one is returned.
+.SH "void QSqlRecord::remove ( int pos )\fC [virtual]\fR"
+Removes the field at \fIpos\fR. If \fIpos\fR does not exist, nothing happens.
+.PP
+Reimplemented in QSqlCursor.
+.SH "void QSqlRecord::setGenerated ( const QString & name, bool generated )\fC [virtual]\fR"
+Sets the generated flag for the field called \fIname\fR to \fIgenerated\fR. If the field does not exist, nothing happens. Only fields that have \fIgenerated\fR set to TRUE are included in the SQL that is generated, e.g. by QSqlCursor.
+.PP
+See also isGenerated().
+.PP
+Reimplemented in QSqlCursor.
+.SH "void QSqlRecord::setGenerated ( int i, bool generated )\fC [virtual]\fR"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Sets the generated flag for the field \fIi\fR to \fIgenerated\fR.
+.PP
+See also isGenerated().
+.PP
+Reimplemented in QSqlCursor.
+.SH "void QSqlRecord::setNull ( int i )\fC [virtual]\fR"
+Sets the value of field \fIi\fR to NULL. If the field does not exist, nothing happens.
+.SH "void QSqlRecord::setNull ( const QString & name )\fC [virtual]\fR"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Sets the value of the field called \fIname\fR to NULL. If the field does not exist, nothing happens.
+.SH "void QSqlRecord::setValue ( int i, const QVariant & val )\fC [virtual]\fR"
+Sets the value of the field at position \fIi\fR to \fIval\fR. If the field does not exist, nothing happens.
+.PP
+Examples:
+.)l sql/overview/insert/main.cpp, sql/overview/insert2/main.cpp, sql/overview/subclass5/main.cpp, sql/overview/update/main.cpp, and sql/sqltable/main.cpp.
+.SH "void QSqlRecord::setValue ( const QString & name, const QVariant & val )\fC [virtual]\fR"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Sets the value of the field called \fIname\fR to \fIval\fR. If the field does not exist, nothing happens.
+.SH "QString QSqlRecord::toString ( const QString & prefix = QString::null, const QString & sep = "," ) const\fC [virtual]\fR"
+Returns a list of all the record's field names as a string separated by \fIsep\fR.
+.PP
+Note that fields which are not generated are \fInot\fR included (see isGenerated()). The returned string is suitable, for example, for generating SQL SELECT statements. If a \fIprefix\fR is specified, e.g. a table name, all fields are prefixed in the form:
+.PP"
+\fIprefix\fR.<fieldname>"
+.SH "QStringList QSqlRecord::toStringList ( const QString & prefix = QString::null ) const\fC [virtual]\fR"
+Returns a list of all the record's field names, each having the prefix \fIprefix\fR.
+.PP
+Note that fields which have generated set to FALSE are \fInot\fR included. (See isGenerated()). If \fIprefix\fR is supplied, e.g. a table name, all fields are prefixed in the form:
+.PP"
+\fIprefix\fR.<fieldname>"
+.SH "QVariant QSqlRecord::value ( int i ) const\fC [virtual]\fR"
+Returns the value of the field located at position \fIi\fR in the record. If field \fIi\fR does not exist the resultant behaviour is undefined.
+.PP
+This function should be used with QSqlQuerys. When working with a QSqlCursor the value(const QString&) overload which uses field names is more appropriate.
+.PP
+Example: sql/overview/update/main.cpp.
+.SH "QVariant QSqlRecord::value ( const QString & name ) const\fC [virtual]\fR"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Returns the value of the field called \fIname\fR in the record. If
+field \fIname\fR does not exist the resultant behaviour is undefined.
