A safe way to convert string to date time in SQL

Over the years while working with SQL Server, I found a safe way of converting string to date time value to be used in SQL. It will have zero risk of being parsed in WHERE clause or cause any performance issues.

Examples:

Convert to DATE type value

SELECT {d '2021-03-01'}

Convert to DATETIME type value

SELECT {ts '2021-03-01 06:10:00'}
