SQL Syntax Error in Power Bi while fetching Data From Diff Tables to Table - Visual

It seems like there might be an issue with the SQL query generated by Power BI while trying to fetch data from your MySQL server. The error message suggests a syntax error in the SQL query.

Here are a few steps you can take to troubleshoot and resolve the issue:

1. Check the Query in Power BI:

   • Open Power BI Desktop.
   • Go to the "Home" tab.
   • Click on "Transform Data" to open Power Query Editor.
   • Review the queries and check if there are any errors or warnings.

2. Check SQL Server for Syntax Errors:

   • If you have access to the MySQL server, you can try running the problematic SQL query directly in a MySQL client to see if it returns any syntax errors.

3. Review Relationships in Power BI:

   • Make sure that the relationships between your tables are correctly defined in Power BI.
   • Check if there are any circular references in your relationships, as this could cause issues.

4. Check MariaDB Connector Compatibility:

   • Ensure that the MariaDB connector you are using in Power BI is compatible with your MySQL server version (8.0).
   • Check for any updates or patches for the MariaDB connector that may address compatibility issues.

5. Check Data Types:

   • Ensure that the data types of the fields used in your visual are compatible and consistent across the tables involved in the relationships.

6. Review Many-to-Many Relationship:

   • Many-to-many relationships in Power BI can be complex. Ensure that your many-to-many relationship between FactTable and table2 is correctly defined.

7. Check for Known Issues:

   • Check Power BI forums or documentation for any known issues related to MariaDB connectors or the specific version you are using.

8. Enable Query Diagnostics:

   • In Power BI Desktop, go to "File" > "Options and settings" > "Options."
   • Under the "Query Diagnostics" tab, enable "Tracing" and "Verbose" options.
   • Refresh the data and check the diagnostic information for more details on the error.

By following these steps, you should be able to identify and resolve the SQL syntax error in Power BI. If the issue persists, providing more details about the specific error message or the generated SQL query could help in providing more targeted assistance.
