Drop Index SQL Example
This sample illustrates use of DROP INDEX statement.
This SQL script contains six queries.
First one deletes table named "developers".
The second creates this table with 3 fields.
Query #3 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 deletes index "UniqueName" from table "developers".
The sixth 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);
drop index developers.UniqueName;
select * from developers;

Testimonials

We made three requests of the technical support personnel and despite the fact that these were all implementation questions (not bugs in their software) we received support within 24 hours. It is rare to get such good customer support these days and I really appreciate everything ComponentAce has done for us.
