What would be the impact in Tableau dashboards when we change datatypes of fields in DB?
In our project few of the data types of columns are going to change INT to BIGINT.
Do we need to take any action from Tableau or will it be refreshed automatically?
We are using live connection.
I just tested this and the report refreshed fine, there was no impact to the report, no warnings or errors. Using Tableau 9.3 and an MSSQL DB.
