Using the UPDATE instruction we can change the value of a field in SQL table easily but when it come to change a word in the field with out changing it all here is the problem. The following instruction solves the problem:
the table is “emp” containing a field “destination” and we need to change the word Sales with Marketing for all the occurrences.
[code="sql"]
UPDATE emp set designation=replace(designation, 'Sales', 'Marketing') where 1
[/code]
