The Oracle UPDATE statement is used to update existing records in a table in an Oracle database.There are 2 syntaxes for an update query in Oracle depending on whether you are performing a traditional update or updating one table with data from another table.The result should not be used if any error occurs when you run the statement.

You can also perform more complicated updates in Oracle.You may wish to update records in one table based on values in another table.There is no guarantee that the order in which the changes are applied to the table and the order in which the rows are inserted into the output table or table variable will correspond. If parameters or variables are modified as part of an UPDATE statement, the OUTPUT clause always returns the value of the parameter or variable as it was before the statement executed instead of the modified value. First Name; SELECT Employee ID, Last Name, First Name, Current Sales, Projected Sales FROM @My Table Var; GO SELECT Employee ID, Last Name, First Name, Current Sales, Projected Sales FROM dbo.
