I'm trying to use query:

but I get error:

firebird_sdbc error:

You don't seem to use a hsqldb but a firebird database and you may want to check http://firebirdsql.org/ for functions supported by firebird.

@Opaque Thank you! - that's another lesson for me. I use the same ods file on 2 systems: windows 10 and linux fedora and I wrongly assumed that if I see HSQLDB on windows it's the same on linux...

I think it depends on the karma. I've fixed the title.

Just as the version of a database is important to refer to documentation, the actual database type is even more important. In Base this can be seen on the bottom line of the main Base screen. Most databases follow standards but also have additional processes not in the standard. This is true for most databases you will come across.

In Firebird there is no Locate but rather Position() (see -> this post).

So the statement previously given for HSQLDB just needs a simple modification to work with Firebird:

SELECT "DATEID", "text_date", LEFT( "text_date", POSITION( '/', "text_date" ) - 1 ) "data_left", RIGHT( "text_date", 4 ) "data_right" FROM "DATETEST"
