MySQL Error 1097: SET Column String Limit Exceeded
Description
MySQL Error 1097, 'Too many strings for column %s and SET', indicates that an attempt was made to store more distinct values in a `SET` column than its allowed maximum. This error typically occurs when inserting or updating data where the input string for a `SET` column contains over 64 unique comma-separated members.
Error Message
Too many strings for column %s and SET
Known Causes
3 known causesExceeding SET Column Capacity
A `SET` data type in MySQL can store a maximum of 64 distinct members. This error occurs when an operation attempts to assign more than 64 unique values to such a column.
Incorrect Data Type Usage
The `SET` column might have been chosen when another data type, like `VARCHAR` for free-form strings or a separate linking table, would be more appropriate for storing a large, variable number of items.
Application Input Generating Excessive Values
The application or script attempting to insert or update data is constructing a string for the `SET` column that inadvertently contains an unusually high number of unique comma-separated values.
