You can parse an expression to determine its parameters and to determine whether the expression is valid.
To parse an expression:
- In the Expression Builder window, create an expression as described in Build an expression.
Click Parse Expression.
If the expression is not valid, an error message is written in red at the bottom of the Expression Builder window.
If the expression is valid, the expression parameters are displayed in the Parameter column in the Parse Expression section. See the figure under Test an expression.
Type a valid value for each of the parameters in the Value column to Test an expression.
For example, type John for the FIRST_NAME and Smith for the LAST_NAME in the Value column. Once you type in values, you can Test an expression.
