My database table has columns email, username and password. I’m trying to insert these

  • 0

My database table has columns email, username and password. I’m trying to insert these test values into them, but the query seems to be interpreting the value for the test email in a strange way.
What’s wrong with this query?

mysql> INSERT INTO `tbl_user`
    -> (`email`, `username`, `password`)
    -> VALUES
    -> (`test1@notanaddress.com`, `Test_User_One`, MD5(`test1`)),
    -> (`test2@notanaddress.com`, `Test_User_Two`, MD5(`test2`))
    -> ;
ERROR 1054 (42S22): Unknown column 'test1@notanaddress.com' in 'field list'

    Try using single quotes rather than backticks round the values, i.e. 

    mysql> INSERT INTO `tbl_user`
-> (`email`, `username`, `password`)
-> VALUES
-> ('test1@notanaddress.com', 'Test_User_One', MD5('test1')),
-> ('test2@notanaddress.com', 'Test_User_Two', MD5('test2'))
-> ;

    Backticks are used to signify column names whereas single(or double) quotes will be used as a value.
