Calling ESQL functions

Most ESQL functions belong to a schema called SQL and this is particularly useful if you have functions with the same name.

For example, if you have created a function called SQRT, you can code:

            /* call my SQRT function  */
 
            SET Variable1=SQRT (4); 

            /* call the SQL supplied function */

            SET Variable2=SQL.SQRT (144);

Most of the functions described in this section impose restrictions on the data types of the arguments that can be passed to the function. If the values passed to the functions do not match the required data types, errors are generated at node configuration time whenever possible. Otherwise runtime errors are generated when the function is evaluated.
