Delete all foreign keys in database(MySql)

Question

I would like to rename a column in a table that is a foreign key to many tables. Apparently this is only possible if you delete the constraints, as I found out in this link.

Answer 1

You Can Try using As Like of Following ..

ALTER TABLE tableName
DROP FOREIGN KEY fieldName;
ADD FOREIGN KEY (newForignKeyFieldName);

Also you can try with Reference Key.As like .....

ALTER TABLE tableName
DROP FOREIGN KEY fieldName;
ADD FOREIGN KEY (newForignKeyFieldName)
REFERENCES anotherTableName(reference_id);
