Let me tell you first why you are getting this 1046 MySQL error message. You might have guessed it right by now; the error message is pretty clear that you have not selected the database before executing your MySQL statement.
This error generally occurs when you try to create a Table in the MySQL database using the command prompt.

When you execute create table statement from MySQL workbench then at that time you need to manually select the database then you execute your statement. Similarly, while executing a script from the command prompt screen, make sure you have provided the database name.

If you do not know the database name:
If you don’t know the available database names or the database on which you are going to execute the script, then you can list all available databases using the following command.
