#include <kexidbfieldlist.h>

List of all members.


Detailed Description

A list of fields.

The KexiDBFieldList can be used to handle KexiDBField objects in a backend-independend way.

Example (in Python) ;

 # Get the tableschema for the "dept" table.
 table = connection.tableSchema("dept")
 # Create a KexiDBFieldList based on the table and filled with the selected fields.
 subfields = ["deptno","name","loc"]
 fieldlist = table.fieldlist().subList(subfields)
 # Create the "SELECT * from dept;" queryschema.
 query = table.query()
 # We change the queryschema to "SELECT deptno,name,loc FROM dept;" now.
 query.fieldlist().setFields(fieldlist)
 # and change the query to "SELECT deptno,name,loc FROM dept WHERE deptno=5;"
 query.setWhereExpression("deptno=5")
 # Execute the query and get a KexiDBCursor object as result which could be used to iterate through the result.
 cursor = connection.executeQuerySchema(query)
