An Example for the Beginners (But NOT for the dummies)

A MySQL database server contains many databases (or schemas). Each database consists of one or more tables. A table is made up of columns (or fields) and rows (records).

The SQL keywords and commands are NOT case-sensitive. For clarity, they are shown in uppercase. The names or identifiers (database names, table names, column names, etc.) are case-sensitive in some systems, but not in other systems. Hence, it is best to treat identifiers as case-sensitive.

SHOW DATABASES

You can use SHOW DATABASES to list all the existing databases in the server.
