How to get the value of a numeric attribute in a SQL Executor transformer and make use of it in a query

Hello,

I would like to get the value that comes from a Counter transformer through the Initiator input in a SQL Executor transformer, to make a query that uses this number

Here is my request:

FME_SQL_DELIMITER ;

alter sequence cajxg_CE_sequence increment by '@Value(COUNTER)';

I tried or without the quotes, I also tried using TO_NUMBER and if I replace my attribute by a number, it works

But when I perform the query I get the error ORA-01722 (Invalid Number)

When I try to do a select with this attribute, it works

Thanks,
