SQLitening Support Forum

I am building a smaller ERP system with Powerbasic and SQLitening. It works as it should when I run in Remote mode. But when I run in Local mode I get "Database locked" every now and then. It does not appear to be a systematic error. Does anyone have a tip where to look for the error?

Hello CJ,

>>Call slSelAry (or slSel once.)

I still will like to make yours work for me.

Hello Bern,

 >>Maybe your client's system has a different (older) version of SQLite .dll installed?

Yeah that was the problem. Installed the latest version for the client and the error vanished. Thanks.

Hi Fred, glad the solution worked for you.

Aside: Is it possible to get the:

1 = near ""WITH": syntax error

on one system and not get it on another system? One of my clients had this error, but it worked fine on my system.

Positive error message number is SQLite error msg, not SQLitening.  Maybe your client's system has a different (older) version of SQLite .dll installed? 

Hi CJ,

I tried your code directly against my database. It compiled and ran without showing any result.

This worked. I am going to test further in the days to come.

Thanks a million.

Yes, there is a master table I called tblBioData which contains the HospitalNo, Surname, Othernames, etc.

Hello CJ,

>>The dummy columns t1,t2,t3 are required to get the correct results.  Please test!

I will test it as soon as I am with my computer. Thanks a lot.

Hello Bern,

>>That's because I used INNER JOINs. You can use LEFT OUTER JOINS if you want results from partial matches, but even so, the table referenced after FROM will control the results set, so the results only return for records in that table. 

Thank you for your explanations.


>>Like I said previously, if you have a fourth table that contains a master list of the Surnames/HopsitalNos, you can use that as the FROM reference and LEFT OUTER JOIN the 3 "SUM" tables from the WITH clause and get a full result set.


Yes, there is a master table I called tblBioData which contains the HospitalNo, Surname, Othernames, etc.

I will follow your instructions and see how it goes. Thanks a lot.

>>Bern routine results: 1 payment record must exist to return results for a client

I also noticed that all three tables needs to have data for a client to return results for that client.

That's because I used INNER JOINs. You can use LEFT OUTER JOINS if you want results from partial matches, but even so, the table referenced after FROM will control the results set, so the results only return for records in that table. 

Like I said previously, if you have a fourth table that contains a master list of the Surnames/HopsitalNos, you can use that as the FROM reference and LEFT OUTER JOIN the 3 "SUM" tables from the WITH clause and get a full result set.
