You can hide one or many columns in SQL and it will show a blue shield with the number of columns hidden. True or False?

Hiding one or more columns in SQL will indeed display a blue shield icon indicating the number of columns that are hidden. This feature is designed to enhance user experience by providing a visual cue that certain columns are not currently visible, allowing for a more streamlined view of the data being worked on.

This functionality is part of SQL management tools that visually represent the metadata and user actions, helping developers to manage their queries and database interactions more effectively. The use of a blue shield with a numerical indication helps users quickly understand the current state of their data visibility and makes it easier to manage complex queries with many columns.

The other options, such as limitations based on SQL versions or specific databases, do not apply to the general functionality of hiding columns in SQL management tools. The visibility features are generally consistent across various setups, making the statement true without restrictions related to specific environments or versions.
