ReadFirstKey cannot find a record

Operating system: macOS
I am checking for an existing invoice like this

IVr2.OfficialSerNr=inline;
if (ReadFirstKey("OfficialSerNr",IVr2,1,true))then begin
...

if inline=VPLT25790C11LT then ReadFirstKey() returns false even though such key exists. I have checked the invoices browse window - the same issue - I cannot find an invoice even it is in the list.
If I search for VPL25866 it works fine.
Is it a bug?

Hi Aldevinas,

The way you described it, it sounds like you might have some corrupted data in your register. I would suggest you to do perform export/import and see if problem persists.


Best Regards,

Data have been imported from customer's test DB. I'll try to replicate it in standard demo.

I am not the original poster. Just one suggestion in case someone encounters this. It happens when you add a new index or modify existing index. Keep in mind indexes are not regenerated when you modify them in datadef.hal New entries which you save AFTER index modification, will have index records and you will find them, but not records before you modified the index. You need to empty and reimport the register to regenerate. There is even a last resort option which I have used in case of seriously corrupted register (--drop-register).


I do not recommend modifying existing index (key) in any way. It is best to use hal command to drop index and recreate it from scratch in datadef.hal. Then clear the register and reimport as mentioned above.

Another cause of the issue you are reporting is when your index is not unique - remember each index must contain all componentes of Main key, even if you think the index would be unique in another way.

My experience :)

I haven't modified any index.
