-==== Run Time Arguments ==== 
  
-XML Catalog or Environment Catalog 
-The environment_name parameter is the environment catalog filespec that OdxSql will connect to. OdxSql will try to connect to the specified environment. If this filespec is not passed as a program argument, then a CONNECT statement must be performed to establish a connection to the environment catalog. 
- 
--use=use_file 
-The -use=use_file parameter instructs OdxSql to process all the commands contained within the specified use file. The right hand side of the parameter, use_file, is the filespec of the file containing the commands. 
- 
-  
-Examples: 
- 
-Running OdxSQL without command line arguments - use the CONNECT command to connect to an XML or Environment Catalog. 
-   ​os>​ odxsql 
- 
-Running OdxSQL with in Environment Catalog. 
-  os> odxsql orders.env 
- 
-Running OdxSQL with a command file of OdxSQL commands. 
-  os> odxsql -use=commands.txt

 ===== Commands ===== ===== Commands =====
  
 +===== Overview =====
 +
 +OdxSQL is used to process a wide range of Omnidex SQL Statements and OdxSQL specific commands.
 +
 +The OdxSQL Commands and Omnidex SQL Statements are organized for quick review as follows:
 +
 +  * [[#​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.
