The UPDATE statement in Oracle is used to modify data in a table. It can be used to update one or multiple rows of data, and to update the values of one or multiple columns at the same time.<\/p>\n

The UPDATE statement allows you to update data based on specified conditions. You can use the WHERE clause to specify the conditions for updating, and only rows that meet the conditions will be updated.<\/p>\n

The basic syntax of the UPDATE statement is as follows:<\/p>\n

UPDATE<\/span> table_name\r\nSET<\/span> column1 =<\/span> value1, column2 =<\/span> value2, ...\r\nWHERE<\/span> condition<\/span>;\r\n<\/code><\/pre>\n
In this case, table_name is the name of the table where data will be updated, column1, column2, etc. are the names of the columns to be updated, and value1, value2, etc. are the values to be updated. The condition is the criteria that must be met for the rows to be updated.<\/p>\n
The following features can be achieved through the UPDATE statement:<\/p>\n
    \n
  1. Change the values of one or several columns in the table.<\/li>\n
  2. Update the data in the table based on conditions.<\/li>\n
  3. Update the data in the table with the calculated results.<\/li>\n
  4. Update the data in the table to match the query results.<\/li>\n<\/ol>\n
    It is important to be cautious when using the UPDATE statement to update data, ensuring that the update operation does not compromise the integrity of the data. Before executing the UPDATE statement, it is best to back up the data to prevent any unexpected issues.<\/p>\n","protected":false},"excerpt":{"rendered":"
