# UpdateLookupTable
<a name="API_UpdateLookupTable"></a>

Updates an existing lookup table by replacing all of its content with new CSV data or CloudWatch Logs query results. After the update completes, queries that use this table use the new data.

This is a full replacement operation. All existing content is replaced. You must specify either `tableBody` or `queryId`, but not both.
