You can check for the value of _tally after the select. If it is 0, the query returned no rows and the array was not created.

if _tally > 0
  *!* do your processing
endif

Alternately you can use type() function

if type("yourarray[1]") = "U"
  *!* array does not exist
else
  *!* do your processing
endif

Or you can use both to be absolutely sure that the array exists

if _tally > 0 and type("yourarray[1]") != "U"
   *!* do your processing 
endif

>Hi,

>I created an array with a SELECT-SQL statement. I know if the SQL statement does not return any records the array doesn't get created. I have some code I need to process only if the array is created. How can I check for this? Is there a command for arrays similar to SELECT() to determine if the array is occupying a work area?
