Power BI Navigation Window Table Name truncated via ODBC

[Mohanasudharsan]

Hello guys,

I am using ODBC connector for Power BI Desktop, in my case the length of my table name is more than 1024bytes.
However when I debug the connector input code, Power BI sends only the 1024 size name alone along with three dots(...).

This leads to the failure of our end users' use case. We have checked the PBI Desktop logs, and it seems we correctly pushed the table name to Power BI via SQLTABLESW call. However, in SQLCOLUMNSW the table name is returned as truncated one of 1024 byte size. Is there any way to fix this issue?

Hi, @Mohanasudharsan 

The official documentation does not specify a limit on the length of column names at this time, and there does not seem to be a straightforward way to increase this limit, as it may be a built-in constraint in Power BI. You can submit an idea for here and the product team will take note of such a need.

Here are some possible workarounds:

1. Please consider shortening the table name to fit the 1024 byte limit.

2. If you are unable to shorten the table name, you can use an alias to reference the table in the SQL query.

3. If the table names are long because they contain many different types of data, consider splitting the table into multiple smaller tables with shorter names.
