WHEREklausuli
The WHERE clause in SQL is a fundamental component used to filter records. It is employed in SELECT, UPDATE, and DELETE statements to specify which rows should be affected by the operation. The clause consists of a condition that evaluates to true or false for each row in the table. Only rows for which the condition evaluates to true are included in the result set or are modified.
Conditions within a WHERE clause are typically formed using comparison operators such as equals (=), not equals
Other useful operators include LIKE for pattern matching in strings, IN to check if a value exists
Effectively utilizing the WHERE clause is crucial for efficient data retrieval and manipulation in relational databases.
