The Oracle REPLACE function is a string manipulation function that allows you to replace one text string with another. It can be a whole word or sentence, or even a single value.
The syntax of the REPLACE function is:
REPLACE ( whole_string, string_to_replace, [replacement_string])
To use this function, the parameters are:
- whole_string (mandatory): This is the string that will be checked for the characters to be replaced.
- string_to_replace (mandatory): This is the string that will be searched for within whole_string.
- replacement_string (optional): This is the string that will be used to replace occurrences of string_to_replace.
Because the last parameter is optional, if it is not specified, then the Oracle REPLACE function removes all occurrences of string_to_replace.
You can replace carriage returns with REPLACE, but you’ll need to use the CHR function.
You can replace NULL values in Oracle, but this is best done with another function such as NVL, rather than REPLACE.
If you want to replace multiple characters, you can do this using nested REPLACE functions or a REGEXP_REPLACE function.
For more information about the Oracle REPLACE function, including all of the SQL shown in this video and the examples, read the related article here:

A cute turkey to begin with.
In this first tutorial, you can learn how to draw a fun turkey mostly made from small rectangles and large circular shapes. The posture of the character is really interesting. Not only is it easier to draw than a front version, but its also easier to add some perspective (as we can see with the legs). The fact that we just need to draw one wing is also interesting.
Most of these cartoon animals are not filled with complex textures or digital effects. In this case, the subject is filled with plain colors and only a few basic details (inside the tail) were added.
A nice turtle also from a side view.
