 ====== Omnidex SQL Reference ======
+{{page>:sql_bar&nofooter&noeditbtn}}
 ===== Overview =====
-Omnidex SQL is a rich implementation of the SQL2 and SQL99 standards along with extensions specific to Omnidex.
-Omnidex SQL statements can be tested and scripted using the [[programs:odxsql:overview|ODXSQL]] program.
+Omnidex SQL is based on ANSI SQL, but also contains extensions that support Omnidex's extended features.
-===== Statements by Type =====
+Omnidex has limited support for Oracle and SQL Server specific SQL extensions such as Oracle decode.
-==== Data Manipulation Statements ====
-| SELECT | Select data |
-| INSERT | Insert data |
-| DELETE | Delete data |
-| UPDATE | Update data |
-| QUALIFY | Qualify rows using Omnidex criteria |
-==== Data Definition Language Statements ====
+Omnidex SQL is available using standard ODBC and JDBC connections.
-==== Index Manipulation Statements ====
+Omnidex provides a high-level SQL interface to access databases enhanced with Omnidex indexes.  The SQL supported is a subset of the ANSI SQL2 and ANSI SQL99 standard along with some very powerful extensions specific to Omnidex.

-==== Miscellaneous Statements ====
-===== All Statements =====
-^Statement^  Description  ^
+SQL should be used for all Omnidex application development including ODBC applications, Java applications using the Omnidex JDBC driver, and OmniAccess applications through oaexecsql. The Query Language extensions work in conjunction with the SQL standard syntax, in all types of applications.
