MySQL no database selected
is an error that occurs when you execute a statement without first selecting a database. The database may be completely missing, or you may choose the wrong database if there is more than one database.
Therefore, if you have more than one database,
know the currently selected database
and on which database your query execution takes place. Read this article to understand MySQL error and how to fix it.
The MySQL1046 (3D000) error occurs when you do not select a database first when executing the MySQL statement.
This error will mostly happen if you are trying to create a table in the MySQL database using the command prompt. While executing a command from the command prompt, you must also select the database. Otherwise, MySQL will not know from which database you are running the script.
MySQL has a command to help you
determine the currently selected database
. This is a quick way to help you ascertain if the problem is genuinely caused by not specifying a database. If the error arises due to not selecting a database, you can easily overcome it by replacing [database_name] with the correct database name in your server.
When creating a table statement from the MySQL workbench, you need to select the database
to run before executing the statement.
Note, the process of choosing the database is manual, not automatic. Similarly, when running a script from the command prompt screen, ensure that you provide that database name.
