Error Variables
|
The following variables can be used for error handling in the script:
The values of all five variables will remain after script execution. The
value of the last four variables, for error handling inside the script, is of
course dependent on the use of ErrorMode=0.
ErrorMode
This variable determines what action is to be taken by QlikView when an error
is encountered during script execution. By default (ErrorMode=1) the script execution will halt and the user will
be prompted for action (non-batch mode). By setting ErrorMode
=0 QlikView will simply ignore the failure and continue script execution
at the next script statement. By setting ErrorMode =2
QlikView will trigger an "Execution of script failed..." error message
immediately on failure, without prompting the user for action beforehand.
Example:
set ErrorMode=0;
ScriptError
Returns the error code of the last executed script statement. This variable
will be reset to 0 after each successfully executed script statement. If an
error occurs it will be set to an internal QlikView error code. Error codes are
dual values with a numeric and a text component. The following error codes
exist:
| 0 |
No error |
| 1 |
General error |
| 2 |
Syntax error |
| 3 |
General ODBC error |
| 4 |
General OLE DB error |
| 5 |
General custom database error |
| 6 |
General XML error |
| 7 |
General HTML error |
| 8 |
File not found |
| 9 |
Database not found |
| 10 |
Table not found |
| 11 |
Field not found |
| 12 |
File has wrong format |
| 13 |
BIFF error |
| 14 |
BIFF error encrypted |
| 15 |
BIFF error unsupported version |
| 16 |
Semantic error |
Example:
set ErrorMode=0;
load * from abc.qvw;
if ScriptError=8 then
exit script;
//no file;
end if
ScriptErrorDetails
Returns a more detailed error description for some of the error codes above.
Most importantly this variable will contain the error message returned by ODBC
and OLE DB drivers for error codes 3 and 4.
ScriptErrorCount
Returns the total number of statements that have caused errors during the
current script execution. This variable is always reset to 0 at the start of
script execution.
ScriptErrorList
This variable will contain a concatenated list of
all script errors that have occurred during the last script execution. Each
error is separated by a line feed.
