This sample illustrates use of CREATE INDEX statement.
This SQL script contains five queries.
First one deletes table named "developers".
The second creates this table with 3 fields.
The third query inserts some data into the table.
The fourth creates index so that "name"+"code" combination must be unique, for field "name" sorting order is descending and is case-insensitive. The new index is given name "UniqueName".
The fifth query retrieves all rows from this table.
drop table developers;
create table developers (
id AutoInc,
Code Integer,
Name varchar(20)
);
insert into developers (code, name) values (2, 'Janet');
create unique index UniqueName ON developers (name desc nocase, code);
select * from developers;
