**Searching and filtering** data in [**SQL Server**](https://www.mindstick.com/articles/333990/understanding-sql-server-management-studio-ssms-and-its-role-in-microsoft-sql-server) is primarily done using the `SELECT` statement combined with various clauses such as `WHERE`, `LIKE`, `IN`, `BETWEEN`, `AND`, `OR`, `ORDER BY`, and more. Here are some common ways to search and filter data:

#### 1. Basic Filtering with `WHERE`

The `WHERE` clause is used to filter records based on specified conditions.

## Example: Filtering by a Single Condition

```plaintext
SELECT * FROM CollegeStudents
WHERE LastName = 'Doe';
```

#### 2. Using `AND` and `OR` for Multiple Conditions

You can combine multiple conditions using `AND` and `OR`.

## Example: Filtering by Multiple Conditions

```plaintext
SELECT * FROM CollegeStudents
WHERE LastName = 'Doe' AND FirstName = 'John';

SELECT * FROM CollegeStudents
WHERE LastName = 'Doe' OR LastName = 'Smith';
```

#### 3. Pattern Matching with `LIKE`

The `LIKE` operator is used for pattern matching. It often includes wildcard characters such as `%` (matches any sequence of characters) and `_` (matches any single character).

**Example: Using** `LIKE` **for Pattern Matching**

```plaintext
SELECT * FROM CollegeStudents
WHERE LastName LIKE 'S%';  -- Last names starting with 'S'

SELECT * FROM CollegeStudents
WHERE FirstName LIKE '_a%';  -- First names with 'a' as the second character
```

#### 4. Filtering with `IN`

The `IN` operator allows you to specify multiple values in a `WHERE` clause.

**Example: Using** `IN` **to Filter by a List of Values**

```plaintext
SELECT * FROM CollegeStudents
WHERE LastName IN ('Doe', 'Smith');
```

#### 5. Filtering with `BETWEEN`

The `BETWEEN` operator is used to filter within a range of values. It works with numbers, text, and dates.

**Example: Using** `BETWEEN` **for Ranges**

```plaintext
SELECT * FROM CollegeStudents
WHERE DOB BETWEEN '2000-01-01' AND '2001-12-31';
```

#### 6. Sorting Results with `ORDER BY`

The `ORDER BY` clause is used to sort the result set by one or more columns.

## Example: Sorting Results

```plaintext
SELECT * FROM CollegeStudents
ORDER BY LastName ASC;  -- Ascending order

SELECT * FROM CollegeStudents
ORDER BY DOB DESC;  -- Descending order
```

#### 7. Combining Filtering and Sorting

You can combine filtering and sorting in a single query.

## Example: Filtering and Sorting

```plaintext
SELECT * FROM CollegeStudents
WHERE DOB BETWEEN '2000-01-01' AND '2001-12-31'
ORDER BY LastName ASC;
```

#### 8. Filtering with Aggregate Functions

You can use aggregate functions such as `COUNT`, `SUM`, `AVG`, `MIN`, and `MAX` in conjunction with the `GROUP BY` and `HAVING` clauses to filter grouped data.

## Example: Using Aggregate Functions

```plaintext
SELECT LastName, COUNT(*) AS NumberOfStudents
FROM CollegeStudents
GROUP BY LastName
HAVING COUNT(*) > 1;
```

#### Note

- `WHERE`: Basic filtering.
- `AND` **&** `OR`: Combining multiple conditions.
- `LIKE`: Pattern matching.
- `IN`: Filtering by a list of values.
- `BETWEEN`: Filtering within a range.
- `ORDER BY`: Sorting results.
- **Combining**: Use filtering and sorting together for powerful queries.

These techniques allow you to effectively search and filter data in SQL Server, tailoring your queries to meet specific needs and extract meaningful information from your database.
