Answer: Option A
Solution (By Examveda Team)
This question asks if using INFORMATION_SCHEMA is more portable than using SHOW statements in MySQL.Let's break it down:
* INFORMATION_SCHEMA: This is a special database in MySQL that provides information about the structure of other databases and tables. It's like a directory that tells you what's inside the database system.
* SHOW Statements: These are MySQL commands used to display information about different aspects of the database, like tables, databases, users, etc.
Portability: This means how easily something can be transferred or used in different environments (like different versions of MySQL or other databases).
Why INFORMATION_SCHEMA is more portable:
* Standardized Structure: INFORMATION_SCHEMA is a standard feature in MySQL and other databases, so the information it provides is structured in a consistent way.
* Consistent Syntax: The queries you use to access information from INFORMATION_SCHEMA are similar across different versions of MySQL.
Why SHOW statements can be less portable:
* Version Differences: The syntax of SHOW statements and the information they provide might change slightly between different versions of MySQL.
* Database-Specific: Some SHOW statements might be unique to MySQL and not available in other databases.
Therefore, the answer is A: True**
INFORMATION_SCHEMA is generally more portable than SHOW statements because it follows a standardized approach across different environments.
