An expression that evaluates to a value of True or False. Expressions should be in the database specific syntax. Any built in capabilities or function of the database platform are available for use within this statement.
Typically, you would compare values using a token, such as "@Data.value~ < 0" or "@Session.AccountNumber~=784635". These statements are used to form the traditional WHERE clause of a SQL statement.
Use single quotes when working with strings: '@Data.myColumn~' = 'SomeValue'
