the two types look the same to me..

chatGPT: The error message you're encountering suggests that there might be some mismatch between the columns you're trying to reference with a foreign key constraint. Even though they both appear to be of the same data type (Char(36)), there could still be some subtle differences causing the incompatibility. Here are a few things you could check: 1. Collation: Make sure that both columns have the same collation. Collation refers to the rules that determine how string data is sorted and compared. If the collations are different, it might cause compatibility issues even if the data types are the same. 2. Character set: Ensure that both columns have the same character set. If one column uses a different character set than the other, it could cause compatibility issues. 3. Constraints: Check if there are any other constraints on either of the columns that might be causing conflicts with the foreign key constraint. 4. Data: Verify that the data in both columns is indeed compatible. Even though they are both Char(36), there could be hidden characters or differences in the actual data that are causing the compatibility issue. 5. Database engine: Sometimes, different database engines may have slightly different interpretations of data types or constraints. Ensure that you're using the same database engine for both columns. By carefully checking these aspects, you should be able to identify and resolve the compatibility issue between the columns. If the problem persists, providing more information about your database schema and the specific SQL query you're using to create the table would be helpful for further diagnosis.
