How can the structure of the output and tag names be modified in SQL?

edit

SQL output and tag names can be modified using the AS keyword in the SELECT statement.

To modify the output name of a column, use the AS keyword followed by the desired name after the column name. For example:

SELECT column_name AS modified_name
FROM table_name;

To modify the tag name of a column, use the AS keyword followed by the desired tag name in square brackets before the column name. For example:

SELECT [tag_name]column_name
FROM table_name;

Both of these methods can be combined to modify both the output name and tag name at the same time. For example:

SELECT column_name AS modified_name, [tag_name]column_name
FROM table_name;
