SQL Function Reference:Oracle vs.SQL Server vs. My SQL Part- I

Generally the major issue we face while development is the availability of common functions in different database(s).

I am facing this issue from last so many years. Then I had start preparing a table for common functions of different database(s).

The commonly used databases are Oracle, Sql Server and My Sql. Their is so many other database(s) are also available but commonly I works on these database(s) only.

Following is the common list of functions in different database(s):-
