Member Function Documentation

QString QSqlIndex::toString(const QString & prefix = QString(), const QString & sep = QLatin1String( "," ), bool verbose = true) const

Returns a comma-separated list of all the index's field names as a string. This string is suitable, for example, for generating a SQL SELECT statement. Only generated fields are included in the list (see isGenerated()). If a prefix is specified, e.g. a table name, it is prepended before all field names in the form:

"prefix.<fieldname>"

If sep is specified, each field is separated by sep. If verbose is true (the default), each field contains a suffix indicating an ASCending or DESCending sort order.

QStringList QSqlIndex::toStringList(const QString & prefix = QString(), bool verbose = true) const

Returns a list of all the index's field names. Only generated fields are included in the list (see isGenerated()). If a prefix is specified, e.g. a table name, all fields are prefixed in the form:

"prefix.<fieldname>"

If verbose is true (the default), each field contains a suffix indicating an ASCending or DESCending sort order.

Note that if you want to iterate over the list, you should iterate over a copy, e.g.

QStringList list = myIndex.toStringList();
QStringList::Iterator it = list.begin();
while(it != list.end()) {
    myProcessing(*it);
    ++it;
}
