Power BI Refresh Error:
1143

What does this error mean?

The MySQL user lacks column-level privileges required for the specific column referenced in the query.

Common causes

  • 1Column-level GRANTs were used to restrict access and the user lacks the required privilege on a specific column
  • 2A SELECT on a view references an underlying column the user cannot access
  • 3UPDATE statement targets a column explicitly excluded from the user's column-level grants

How to fix it

  1. 1Step 1: Check column-level grants: `SHOW GRANTS FOR 'your_user'@'%';`
  2. 2Step 2: Grant column-level access: `GRANT SELECT (col1, col2) ON your_db.your_table TO 'your_user'@'%'; FLUSH PRIVILEGES;`
  3. 3Step 3: Alternatively, revoke column-level restrictions and grant table-level access: `GRANT SELECT ON your_db.your_table TO 'your_user'@'%'; FLUSH PRIVILEGES;`

Frequently asked questions

When should I use column-level grants in MySQL?

Use column-level grants when a service account needs access to some columns in a table but not others (e.g., excluding PII columns). For ADF and dbt service accounts, table-level grants are simpler and less error-prone.

How do I remove column-level restrictions and use table-level grants instead?

Run `REVOKE ALL PRIVILEGES ON db.table FROM 'user'@'%'; GRANT SELECT ON db.table TO 'user'@'%'; FLUSH PRIVILEGES;` to replace column restrictions with full table access.

Can MetricSign detect when column-level restrictions break a pipeline?

Yes — MetricSign captures ADF pipeline failures with the MySQL error code so you can see immediately when a column permission issue is blocking data flow.
