Detailed Description
A list of fields.
The KexiDBFieldList can be used to handle KexiDBField objects in a backend-independent 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)
