Transact-SQL string and datetime functions

Standard SQL-92 specifies few functions for treatment of strings and dates. For example, the CURRENT_TIMESTAMP function returns both the current system date and the time. In addition, there are functions, which return one of the components.

In view of that restriction, language realizations expand standard by introducing the functions that make handling of these data types more convenient for users. It should be noted that standard compatibility at the Entry Level does not require support of standard functions for these data types.
