Why Does the Error Occur?
In MySQL, when creating an index on a column we have the option to specify a length for the index. This length indicates the number of characters or bytes to the index from the column’s value. However, if we attempt to create an index without specifying a length MySQL will throw the “key specification without the key length” error. This is because MySQL requires explicit index lengths for certain data types such as the text to ensure efficient indexing and storage.
