Show The ability to submit SQL statements enables you to issue complex queries to the database. This is useful if you want to use database features specific to a particular database platform. The SQL statement you use to set a field value in the Set Fields action has a different result than the Direct SQL action (see Defining Direct SQL active link, filter, or escalation actions). In the Set Fields action, you use SQL to search the database for information and then use the returned values to set fields. With the Direct SQL action, the SQL command is not expected to return a value. To run more than one SQL command, use stored procedures or functions or any other extension supported by your database. A stored procedure with a Set Fields action executes all its commands but does not return a value. For the most effective use of SQL statements, you must have a general understanding of relational databases and a specific understanding of the relational database underlying your AR System . Warning Because AR System passes SQL commands to the database without checking the syntax, all commands are submitted to the database. Make sure all submitted commands achieve the needed result. Your SQL commands should comply with ANSI SQL standards, so that single quotes are reserved for strings, and double quotes are reserved for use with database object names only.

To use SQL commands, familiarize yourself with the features of your underlying database. For Oracle, Microsoft SQL Server databases, all SQL commands are issued by the ARAdmin user (or the AR System Database User defined during installation). Depending on which database you are using, the data must be accessible to the user issuing the command. If you are running AR System as one of these users without permission to access the database, you cannot issue the SQL command. What are the 5 SQL statement types?Types of SQL Statements.
