What is the correct syntax to do a SQL Update on a column and divide its values by 1 000 000?
363
We can update multiple columns by specifying multiple columns after the SET command in the UPDATE statement. The UPDATE statement is always followed by the SET command, it specifies the column where the update is required. UPDATE table_name SET column_name1= value1, column_name2= value2 WHERE condition;
SET column1 = value1, column2 = value2, ... Note: Be careful when updating records in a table! Notice the WHERE clause in the UPDATE statement. The WHERE clause specifies which record (s) that should be updated. If you omit the WHERE clause, all records in the table will be updated!
The simplest example of the division operator is: You can execute this query, and it will output the result – in this case, 5. However, it is more likely that you will be working with integers that reside in columns as part of your database tables. Let’s look at such an example.
