Oracle

In Oracle, UPDATE statement is used to update the existing records in a table.

Syntax:

UPDATE table 
SET column1 = expression1,  
column2 = expression2,  
 ...  
column_n = expression_n  
WHERE conditions;  

Example:

UPDATE students  
SET sname = 'Rosy' 
WHERE student_id = 2102;  

Here , sname 0f Student_id = 2102 is changed to "Rosy".
