pymysql.err.DataError: (1406, "Data too long for column 'in_content' at row 1")

This error occurs when you are trying to insert data into a MySQL table, and the value you are trying to insert is too long for the specified column.

In this specific case, the error message indicates that the value you are trying to insert into the 'in_content' column is too long for the column's data type.

To fix this error, you will need to either shorten the value you are trying to insert, or alter the column's data type to allow for longer values.

Here are some steps you can take to resolve this error:

1. Check the length of the value you are trying to insert into the 'in_content' column.

2. If the value is longer than the maximum length allowed for the column's data type, you will need to shorten it.

3. Alternatively, you can increase the length of the 'in_content' column by altering the table's schema.

4. To alter the table's schema, you can use a SQL statement like this:

ALTER TABLE my_table MODIFY COLUMN in_content VARCHAR(255);

This statement would increase the maximum length of the 'in_content' column to 255 characters. You can adjust the length as needed for your specific use case.

5. Once you have made the necessary changes, you can try inserting the value again and see if the error is resolved.
