Qt 3 Support Members for QSqlIndex
The following class members are part of the Qt 3 support layer. They are provided to help you port old code to Qt 4. We advise against using them in new code.
Public Functions
QString | toString ( const QString & prefix = QString(), const QString & sep = QLatin1String( "," ), bool verbose = true ) const |
QStringList | toStringList ( const QString & prefix = QString(), bool verbose = true ) const |
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;
}
