#include <QSqlIndex>
Part of the QtSql module.
Inherits QSqlRecord.
The QSqlIndex class provides functions to manipulate and describe database indexes.
An index refers to a single table or view in a database. Information about the fields that comprise the index can be used to generate SQL statements, or to affect the behavior of a QSqlCursor object.
Constructs an empty index using the cursor name cursorname and index name name.
Constructs a copy of other.
Destroys the object and frees any allocated resources.
Appends the field field to the list of indexed fields. The field is appended with an ascending sort order.
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Appends the field field to the list of indexed fields. The field is appended with an ascending sort order, unless desc is true.
Returns the name of the cursor which the index is associated with.
Returns true if field i in the index is sorted in descending order; otherwise returns false.
Returns the name of the index.
Sets the name of the cursor that the index is associated with to cursorName.
If desc is true, field i is sorted in descending order. Otherwise, field i is sorted in ascending order (the default). If the field does not exist, nothing happens.
Sets the name of the index to name.
Sets the index equal to other.
