To delete the contents of a column in a MySQL table, you can use an UPDATE statement to update the column contents to NULL or use an ALTER TABLE statement to delete the column.<\/p>\n

    \n
  1. Update the column content to NULL using the UPDATE statement.<\/li>\n
  2. Update the table name, setting the column name to NULL.<\/li>\n
  3. For example, to delete the content of column named “score” in a table named “students”, you can execute the following statement:<\/li>\n
  4. Change the scores of all students to null.<\/li>\n
  5. Delete a column using the ALTER TABLE statement.<\/li>\n
  6. Drop the column from the table.<\/li>\n
  7. For example, in order to remove the column named “score” from a table named “students”, you can execute the following statement:<\/li>\n
  8. Remove the column “score” from the students table.<\/li>\n
  9. Please note that this will completely delete the column from the table, and the data in that column will be permanently lost. Before using this method, make sure to back up your data or verify that deleting the column will not result in data loss.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
