Microsoft SQL ServerDelimiting special characters and reserved words


Generally speaking, it is best not to use T-SQL Reserved Words as table names, column names, programming object names, alias etc. So the method to escape these keywords should only be applied if you are inheriting a database design that cannot be changed.

For reserved words, usage of the square brackets is not mandatory. When using a tool such as SQL Server Management Studio, the reserved words will be highlighted to bring attention to the fact that they are reserved.
