Dear friends,

I am uning the Jira conector to get details about Issues openend. A few days ago was necessary to execute a migration on Jira and with this action the custom fields received the sufix (migrated).

After this process a facing to use the Dataset on SQL process.

The system has return the folowing error message:

""Identifier name must be 64 characters or less: 'DOD.6. Segurança e Negócio: Foram verificados os itens abaixo? (migrated 2)'."

Someone has a idea how to deal whit this problem.

    Hi @user025461

    This is because MySQL 5.6 (version Domo is built off of) doesn't support column names longer than 64 characters. You have a few options to work around this issue.

    1) Use a Dataset view (or a magic ETL) to rename your column to something less than 64 characters and then use that dataset inside your MySQL dataflow

    2) (Better Option) Convert your dataflow to a MySQL Magic ETL 2.0 dataflow which will be much more performant and support the longer column names.

    Is that error referencing a column name, or the data in a particular column?

    Hi Grant,

    How does it work to convert the Dataflow to MySQL 2.0 ?

    I already solve my problem treating the field name in ETL, but this action could help me in another situations.

    Apologies, I had MySQL on the brain but mean to state Magic ETL 2.0.
