 {{page>:odxsql_bar&nofooter&noeditbtn}}
-===== Overview =====
-OdxSQL is used to process a wide range of Omnidex SQL Statements and OdxSQL specific commands.
+OdxSQL processes Omnidex SQL statements and OdxSQL specific commands either interactively or in batch oriented script files via the USE command.
-The OdxSQL Commands and Omnidex SQL Statements are organized for quick review as follows:
+The following is a list of Omnidex SQL Statements and OdxSQL commands organized by type with a complete alphabetic list shown below.
-  * [[#Connecting and Disconnecting ]]
-  * [[#Omnidex SQL Data Definition Language (DDL) Statements ]]
-  * [[#Omnidex SQL Data Manipulation Language (DML) Statements ]]
-  * [[#Omnidex Environment Operation Commands ]]
-  * [[#OdxSQl and Omnidex SQL Data Export and Manipulation ]]
-  * [[#OdxSQL Program Operation Commands ]]
-  * [[#OdxSQL Testing and Performance Commands ]]
-  * [[#OdxSQL Operating System Commands ]]
-  * [[#Omnidex Index Direct Maintenance Routines ]]
-  * [[#Alphabetical List of OdxSQL Commands and Omnidex SQL Statements ]]
-OdxSQL Commands and Omnidex SQL Statements can be entered into OdxSQL in ether upper or lower case.
-  > connect myenv
-  > CONNECT myenv
-The syntax for Omnidex SQL Statements entered into OdxSQL or processed in a script file is typically the exact same syntax and returns the exact same results.
-There are a few exceptions such as CONNECT and VERSION.
-In OdxSQL, CONNECT has two additional options of ON host:port and USING api that are not available in the Omnidex SQL CONNECT Statement.  The api is not necessary has it is already known depending on the application type (ODBC or JDBC) and ON
-In OdxSQL, the VERSION command displays the OdxSQL header and multiple lines of version information where the Omnidex SQL VERSION statement returns a single line.
-The OdxSQL EXECSQL command can be used to verify if an Omnidex SQL Statement is processed exactly the same by OdxSQL as the Omnidex SQL parser.
