This command returns a result set containing the names of all databases present on the server.

Showing Tables

If you want to retrieve information about the tables within a specific database, you can use the SHOW TABLES command. This command provides a list of tables that exist in the selected database. Here’s an example:

SHOW TABLES FROM my_database;

By replacing “my_database” with the name of your desired database, you can obtain a detailed overview of its tables.

Showing Columns

To examine the columns of a particular table, you can use the SHOW COLUMNS command. It provides valuable insights into the structure of a table, including column names, data types, and any constraints applied. Here’s how you can use it:


Replace “my_table” with the name of your desired table, and the command will return a result set containing detailed information about each column.

Showing Indexes

If you need to retrieve information about the indexes defined on a table, you can employ the SHOW INDEX command. It provides a list of indexes associated with the specified table, including the column(s) they are based on. Here’s an example:


By replacing “my_table” with the name of the table you want to inspect, you can obtain crucial details about its indexes.
