Hi,
My form allows the user to imput criteria in a search box and then click a SEARCH button or press ENTER to return a matching result of a record from an ODBC connected database. There should only be one unique match to return as the user is entering an ID number.
I am stuck on providing a nice error message if the search returns no records e.g. if the user search an invalid ID number. Currently the user is getting the ugly XFA error:
Script Failed (language is formcal; contxt is xfa[0].form[0]topmostSubform[0].Page1[0].Button1[0]) script=... Error: first operation failed there are no records in the datasource.
I don't know how to catch the null recordset without an XFA error and instead throw my own custom messagebox at the user. I am suck on catching the error or EOF and using it as a trigger to run a custom message box.
In my research I believe the solution might involve using EOF Action settings. Unfortunatly I haven't been able to find much documentation or practical examples of it's ugage. Whenever I've tried to expiriment I've only ended up with broken code/script. I have no idea to work with EOF's.
Here is my current formcalc script when the user clicks the search button:
//Define SQL to run
var oDC = Ref($sourceSet.EstabSearchResults.clone(1)) //Cloning of the SourceSet due to using XFA Specification 2.5 or higher.
oDC.#command.query.commandType = "text"
oDC.#command.query.select = concat("SELECT ESTAB_NAME, OWNER_NAME, ESTAB_ADDRESS, ESTAB_CITY, [...more SQL query criteria....] FROM ESTABLISHMENT WHERE (GAZ_NUMBER LIKE '",EstabSearchField.rawValue,"');")
//Do the new connection
oDC.open()
oDC.first()
How do I catch an EOF or null recordset when oDC.first() is run?
Also, sorry I don't really have good examples of what I've tried. My attempts were laughable. Any ideas or suggestions on how to work with this scenario would be greatly appreciated.
Thanks!
-Mike
