Question
Which SQL operator would you use to select records where a column's value matches any value in a set of values?
ANY
IN
ALL
EXISTS
Solution
You would use the IN
operator in SQL to select records where a column's value matches any value in a set of values. Here's a step-by-step guide on how to use it:
- Start with the
SELECT
statement: This is used to select data from a database. The data returned is stored in a result table, called the result-set.
SELECT column1, column2, ...
- From the
FROM
statement: This is used to specify which table to select or delete data from.
FROM table_name
- Then use the
WHERE
clause: This is used to filter records, and is used to extract only those records that fulfill a specified condition.
WHERE column_name IN (value1, value2, ...);
Here's an example:
SELECT * FROM Customers
WHERE Country IN ('Germany', 'France', 'UK');
In this example, the IN
operator selects all records where the "Country" column has a value of 'Germany', 'France', or 'UK'.
