Q. Which statement is used to show the server's current character set and collation settings?

Explanation by: Vikash Gupta

This question is asking about how to find out what character set and collation your MySQL server is using. These settings determine how text is stored and compared in your database. Here's a breakdown of the options: * Option A: SHOW CONSTANTS - This command shows various constants defined within MySQL. It's not directly related to character sets and collations. * Option B: SHOW CONSTRAINTS - This command shows the constraints defined on tables in your database. It's not related to server settings. * Option C: SHOW VARIABLES - This is the correct answer! This command displays all system variables and their current values. This includes the character set and collation settings for the server. * Option D: DISP VARIABLES - This is a synonym for SHOW VARIABLES. Both commands do the same thing. In summary, the correct answer is Option C: SHOW VARIABLES.
