I'm making a ETL in Talend that add data in a table.
The table is for a old system and the primary key is not auto-incremental. So I have to get the maximum id plus one every time that I insert a value in the table.
I'm trying to use a var in the Expression Builder:
then in the Expression Builder:
Context.Max += 1
The problem is that every time I get the same id, I need to save the sum.
Finally I found what was looking for:
Numeric.sequence("var2", Context.Max, 1)
This increment by 1 the Context.Max
and save it in "var2"
.
