what version Sqlite database does this work with?

I have queries that use INSTR and REGEX, which I believe are in Sqlite V3 Databases and run fine on my database using SQLiteStudio 3.2.1 from my desktop, but when I try to use the same queries in B4J I get errors such as java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (no such function: INSTR)

thanks,
kev

I think my question is redundant, as I have again got the SQL queries to work!!!

I was originally wanting to populate a Tableview with the results, but then decided to change to a B4Xtable instead. This somehow broke the SQL, even without trying to populate the B4Xtable. Removing the B4Xtable in Designer and replacing with a Tableview fixed it.

I cannot see how this action in the form designer could be related to running the SQL, but it somehow is... Erel?

Hi Kevin
I don't think this is related to jdbc version, and this post of yours shows it.
According to SQLite documentation (which you can find HERE), REGEX depends on the existence of a user function regexp() which is not defined in SQLite by default, so I believe your SQLIteStudio DLL version implements the regexp() function.
I use SQLiteExpert with the "official" SQLite DLL which does not implement regexp().
As SQLite is open source, there are several DLL versions around which are not supported/maintained by the sqlite.org team, so I would refrain from using such versions.

As for B4XTable breaking your code, you should start a new thread on this, as Erel suggested.
