Example
When a column name matches a reserved keyword, standard SQL requires that you enclose it in double quotation marks:
SELECT
"ORDER",
ID
FROM ORDERS
Note that it makes the column name case-sensitive.
Some DBMSes have proprietary ways of quoting names. For example, SQL Server uses square brackets for this purpose:
SELECT
[Order],
ID
FROM ORDERS
while MySQL (and MariaDB) by default use backticks:
SELECT
`Order`,
id
FROM orders
