Check the logs of tidb-server, as well as the slow queries and SQL analysis in the Dashboard, to see the specific abnormal information.

Filter slow queries.

The TiDB service seems to be abnormal. Check the logs.

Use tiup cluster display <cluster-name> to check if all components are functioning properly.

Are there any errors in the TiDB logs?

| username: TiDBer_vFs1A6CZ | Original post link

The cluster is normal, but I suspect that a certain query statement has a problem. I want to know how to locate the abnormal query statement.

There are no errors reported in the TiDB logs? These are all TiDB query anomalies.

[ERROR 1364 (HY000): Field ‘xxx’ doesn’t have a default value

Did you change the table structure?

| username: TiDBer_vFs1A6CZ | Original post link

Thank you. By identifying the 1364 error, I found the table corresponding to the abnormal query and located the issue where the upstream data source had modified the table structure fields.

The admin show ddl command can display DDL statements.

The error should have been recorded at the application layer, right?

Query failed. You can copy the corresponding SQL statement and execute it in the client to see if there are any errors. This situation is mostly caused by changes in the table structure.
