I was wondering if someone has any idea on how to use data types "Long" and "Decimal"
I have a file which has these kind of data types, and i wanted to read in Talend.
It depends - what You really have in Your file,
- long is unsigned BIGINT
- decimal is numeric with decimal point
You can check more about conversion if create in repository new JDBC connection, select General JDBC and than open Mapping file which better relate to Your source.
Inside You will find DB <-> Talend suggested datatypes conversions
