iQuery.ifsExists() - UDF
Published by: Bob Cozzi on 17 Jun 2019 view comments
Check IFS File Exists
The iQuery.ifsExists() UDF checks if the specified IFS file exists on the IFS. If it exists, it returns 1, otherwise it returns 0.
Parameters
iQuery.ifsExists( 'IFS file and path' )
The IFS File and Path parameter identifies the name of the IFS file to confirm that it exists. If the file exists, the UDF returns 1 otherwise it returns zero (0).
Return Value
| UDF | Return Type | Description |
| ifsExists | integer | A returned value of 0 means the files does NOT exist. A returned value of 1 means the file was found. |
Example
select iQuery.ifsExists('/home/cozzi/order12345.pdf') INTO :Exists
from sysibm.sysdummy1;
if (exists = 0); // File does not exist?
// create the IFS file
endif;
