DBExecute on MariaDB (Mapping of Clover fields

Hi

When doing an SQL-Update with DBExecute in a MariaDB

update ADRESSEN
set ADRESSEN.VStatus = ‘CHG’
where ADRESSEN.MCC_NUMERO = $MCC_NUMERO

an error “Unknown column ‘$MCC_NUMERO’ in ‘where clause’” is triggered. I used statements like that with other database with no problems.
I already tried “$in0MCC_NUMERO”

Why does this not work ?
Any suggestions ?

Thanks
Otto

CloverDX v5.13.1.3 & Clover v5.13.2.24

Switching from DBExecute to DatabaseWriter solved the case

Thanks
