hey bro code
i'm trying to tape the same scrito but i get this error:
''Error Code: 1046. No database selected Select the default DB to be used by double-clicking its name in the SCHEMAS list in the sidebar.''
how to solve it please
Hello sir,
I'm glad that i found your channel to learn SQL. I'm completely new to this subject.
i came across an error while creating a table column (" hourly pay decimal(5,1)"). could you please clarify?
I completely forgot how to do MySQL, after a year of not taking a subject that utilizes it.
Now I suddenly have an assignment due by midnight. So I just quickly needed a refresher.
Thank you for providing a short and to-the-point tutorial.
Just wow❤
ОтветитьLegendary !
ОтветитьThe Modify clause isnt working. It does'nt highlight or anthing like ALTER or SELECT, almost as if mysql is reading it as normal txt. Anyone else has this problem?
ОтветитьFor numbers suppose if this is a real life job scenario, do we still use VARCHAR as a data type or is there any alternative to add larger numbers in a database? Like in Java you can use double or even long so is there something similar?
