Not so smart of me!
Overenthusiastic I proposed something impossible …:
Package-functions can only have synonyms by their package-name, so the package name still has to be used like Hootbah mentioned.
What can be done is use one schema to place all conversion functions in so you can use the synonyms proposed (to avoid using the schema-name) and can easily maintain them. But that can’t be called any news …

Using a package is a good idea (maintainability) and in combination with synonyms exactly like the MySql function names (without the package prefix) makes it easy to use as well.

It would be a good idea to wrap the functions in a package. However in doing this you would have to change all the sql queries where one of these function is being used. To call a function in a package you have to call it by package_name.function_name For example if we wrapped the date functions up into a package called mysql_dates you would call the now function like:

SELECT mysql_dates.now FROM dual;

As opposed to the method without the package:

SELECT now FROM dual;

To make porting easier its probably better not to wrap these functions in a package.

Wouldn’t it be better to create an Oracle Package to contain the Functions? That way it can be extended to include any other functionality required.
