The WHERE clause is used to filter records in a table.
It allows SQL to return only specific data instead of all records.
Filtering data is very important in real applications.
Without the WHERE clause, SQL selects all rows from a table.
Using conditions helps retrieve only required information.
This improves performance and accuracy.
Conditions are written using comparison operators.
Operators such as equal, greater than, and less than are commonly used.
These conditions decide which rows are selected.
The WHERE clause is written after the table name.
It applies rules to filter rows based on column values.
Only matching records are processed.
WHERE clause is heavily used in search, filters, and reports.
Almost every backend feature uses conditional queries.
Understanding WHERE is essential for writing real SQL queries.
