Function: try()

Evaluates an expression and returns its value unless an error has occurred. If an error occurs, the error value is placed into an internal variable called _error and the 2nd expression is evaluated.

Syntax

try(expression1, expression2)

ArgumentTypeDescription
expression1ExpressionAny valid expression
expression2ExpressionAny valid expression


Examples

The first expression tries to convert crm.total to a number. If the conversion fails, the reason for the failure is stored in the internal variable _error. This value, along with a value from the in pipe is stored in the user defined $SysError variable, and a value of -1 is returned.

try( 
   $val = toNum(crm.total), 
   do( 
      $SysError = _error + in.accountKey, 
      -1 
   ) 
)
