In MySQL, you can use the CHARACTER_MAXIMUM_LENGTH information schema to query the length of table fields. Here is an example SQL query for retrieving the maximum length of a field in a table.

SELECT COLUMN_NAME, CHARACTER_MAXIMUM_LENGTH
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = 'your_database_name' 
AND TABLE_NAME = 'your_table_name'
AND COLUMN_NAME = 'your_column_name';

Please replace ‘your_database_name’, ‘your_table_name’, and ‘your_column_name’ in the statement with the name of the database, table, and column you want to query.

This SQL query will return the maximum length of the specified columns. I hope this is helpful to you. Let me know if you need further clarification or have any other questions.
