What are some common ways to write an SQL Update statement?

The SQL Update statement is used to update records in a database table, with commonly used syntax options including the following:

1. Update the value of a single field:

UPDATE table_name
SET column_name = new_value
WHERE condition;

1. Update the values of multiple fields.

UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;

1. Updating field values using a subquery.

UPDATE table_name
SET column_name = (SELECT new_value FROM another_table WHERE condition)
WHERE condition;

1. Update the value of a field using a CASE statement.

UPDATE table_name
SET column_name = CASE
    WHEN condition1 THEN value1
    WHEN condition2 THEN value2
    ELSE default_value
END
WHERE condition;

1. Update the value of a field using a JOIN statement.

UPDATE table1
JOIN table2 ON table1.id = table2.id
SET table1.column_name = table2.new_value
WHERE condition;

Here is a common way to write an SQL Update statement. Choose the appropriate method based on the actual requirements to update records in the database table.
