The DROP table command of SQL lets you drop a table from database . The database requires you to empty a table before you eliminate from the database. But there is a condition for dropping a table ; it must be an empty table.
It may depend on what flavor of SQL, but whenever you want to get rid of something, DROP is generally your friend. DROP INDEX <indexname>; is likely to be the command needed, with various options depending on, again, exactly what flavor of SQL you're talking about.
From the output of the "show ip interface brief" command, you can see the IP address, interface status (up or down), protocol status (up or down), and the method for obtaining the address (manual or dynamic) for each interface on the device.
The SQL command UPDATE can be used to change contents of one database using the contents of another database by joining them on a common key field. You would typically use a query with a join condition between the two tables based on the common key field to update the fields in the target table with values from the source table.
The SQL command that can be used to retrieve all data from a table is the SELECT Ex: Let us say we have a table called employee_master which contains 3 columns emp_name, emp_number, date_of_joining you can retrieve all the data by using the below command SELECT * FROM employee_master or SELECT emp_name, emp_number, date_of_joining FROM employee_master
You will need a server-side language (and, obviously, a database) to accomplish that. Here's a very simple example, using PHP and MySQL. ---- <?php // Connect to MySQL and select a database (if either one fails, stop the script) $connect = mysql_connect('username', 'password') or exit('Connection failed.'); $select = mysql_select_db('database') or exit('Database Selection failed.'); // Retrieve data from the database. $sql = "SELECT `name` FROM `fruits`"; $query = mysql_query($sql); if (!$query) { exit('The query failed.'); } // Create a drop-down box. echo "<input type='select'>"; // For each row returned, create an option element for it. while ($fruit = mysql_fetch_assoc($query)) { echo "<option>"; echo $fruit['name']; echo "</option>"; } // End the drop-down box. echo "</select>"; ?>
The DROP command allows you to delete things such as tables or indexes.

To drop an index in a database, you need to use a specific SQL command. First, you identify the name of the index you want to drop. Then, you use the DROP INDEX statement followed by the name of the index. This command removes the index from the database, making the associated data searchable without the index.
