| - | Omnidex can automatically generate the CREATE ENVIRONMENT, CREATE DATABASE, CREATE TABLE and CREATE INDEX statements needed for an Omnidex Environment File. The [[dev:sql:statements:extract:home|EXTRACT]] statement is used to connect to the MySQL database, query the underlying schema information, and generate the appropriate statements. This statement can be issued through OdxSQL, or through any ODBC or JDBC application. | + | Omnidex can automatically generate the CREATE ENVIRONMENT, CREATE DATABASE, CREATE TABLE, and CREATE INDEX statements needed for an Omnidex Environment File.
