DROP TABLE
A DROP TABLE command is used to remove a table created with a CREATE
TABLE or SELECT INTO command from both the database and the environment
access cache. Tables can only be dropped during the same Omnidex process
in which they were created. Omnidex is unaware of the existence of tables
created in separate processes unless they are defined in the Omnidex Environment
Catalog.
To remove a table created with a CREATE TABLE or SELECT INTO command
in a different process, use the appropriate RDBMS tool.
Syntax

Example
This example creates an empty table named CUSTS using a CREATE TABLE
command, inserts some rows into the table, runs a select statement against
that table and then drops the table.
>CREATE TABLE CUSTS (CUSTOMER CHAR LENGTH 40)
Table CUSTS created
>
Insert a row using the INSERT INTO command.
>INSERT INTO CUSTS VALUES ('JANE SMITH')
1 row inserted into CUSTS
>
>INSERT INTO CUSTS VALUES ('JOHN SIMPSON')
1 row inserted into CUSTS
>
Select rows from the new table using the SELECT command.
>SELECT * FROM CUSTS
CUSTOMER
----------------------------------------
JANE SMITH
JOHN SIMPSON
Note that because the new table is not indexed, selects are preformed
by serial read.
Drop the table using the DROP TABLE command.
>DROP TABLE CUSTS
Table CUSTS dropped
