__evalVar

Also documented in context in the full Functions and Variables reference.

The evalVar function returns the result of evaluating an expression stored in a variable.

This allows one to read a string from a file, and process any variable references in it. For example, if the variable “query” contains “select \${column} from \${table}” and “column” and “table” contain “name” and “customers”, then \${__evalVar(query)} will evaluate as “select name from customers”.

Name	Required	Description
Variable name	Yes	The variable to be evaluated.
