- Identify the query causing the error. Check application logs or enable the MySQL general log temporarily to capture the problematic SQL statement:
SET global general_log = 1;
SET global log_output = 'table';
After capturing the query, disable logging:
SET global general_log = 0;
- Examine the table schema for column definitions related to the error. Use the `DESCRIBE` command:
DESCRIBE yourtablename;
- Identify the column mentioned in the error and check its data type limits (e.g., INT, VARCHAR). Compare these limits with the data you are trying to insert or update.
- If the issue is due to an integer type limit (e.g., trying to insert a value larger than the maximum allowed for an INT), consider changing the column data type to a larger type (e.g., BIGINT) if data correctness allows:
ALTER TABLE yourtablename MODIFY yourcolumnname BIGINT;
- For VARCHAR or similar types, ensure the data you're inserting does not exceed the column's defined length. If necessary and appropriate, adjust the column length:
ALTER TABLE yourtablename MODIFY yourcolumnname VARCHAR(new_length);
- Re-run the problematic query to confirm the issue is resolved.
- Optionally, if the error persists or you suspect data corruption, check the table for issues:
CHECK TABLE yourtablename;
- If step 7 indicates table issues, attempt a table repair (back up the table first):
REPAIR TABLE yourtablename;
