Why do i see 'subquery returns more than 1 row' in sql?
Example:
UPDATE users SET name = (SELECT name FROM anotherUsers WHERE id = 1);
The subquery used in the SQL statement is returning multiple rows, while the context expects only a single row.
Solution:Modify the subquery to ensure it returns only one row, or use SQL functions like IN if multiple values are acceptable.
UPDATE users SET name = (SELECT name FROM anotherUsers WHERE id = 1 LIMIT 1);
