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.
createtable developers (
insertinto developers (code, name) values (2, 'Janet');
createuniqueindex UniqueName ON developers (name desc nocase, code);
select * from developers;
