Column was renamed or dropped in a schema migration without updating the pipeline or model. Typo in the column name. Column exists in a different schema or table than the one being queried. Case sensitivity issue — column name differs in case from the identifier in the query

Step 1: Check the current columns: `\d ` or `SELECT column_name FROM information_schema.columns WHERE table_name=' ';`. Step 2: Update the query or dbt model to use the correct column name.. Step 3: If column was renamed, add a migration or alias: ` AS `.. Step 4: Enable schema change alerts in MetricSign to catch column drops before they break pipelines.
