Mysql special plate. ♪



  • There's a sign in mysql, a special one that's used to follow up on requests from no plate. ♪

    Question, what is it called? I used it a long time ago, and I can't remember.

    I'll explain.

    SELECT 'test_value' as nanme FROM dummy_table
    

    This request is completely unrelated to any existing plate, and for this purpose, there is this special plate in mysql. dummy_tabl



  • Table dual:

    SELECT 'test_value' as nanme FROM dual
    

    or simply:

    SELECT 'test_value' as nanme
