How Can I Combine LIKE and IN Operators in SQL Server Queries for Pattern Matching?

Cleverly combines the LIKE and IN operators in SQL Server to achieve pattern matching

In SQL Server, the LIKE operator is used for pattern matching, while the IN operator allows searching for a value in a specified list. However, combining these two operators can be tricky.

Combination of LIKE and IN operators

To combine LIKE and IN, we can take advantage of the fact that the IN operator actually creates a series of OR statements. For example, the following query:

<code class="language-sql">SELECT * FROM table WHERE column IN (1, 2, 3)</code>

is equivalent to:

<code class="language-sql">SELECT * FROM table WHERE column = 1 OR column = 2 OR column = 3</code>

So, to combine LIKE and IN, we can create a series of OR statements for LIKE comparisons. For example:

<code class="language-sql">SELECT * FROM table
WHERE column LIKE 'Text%' OR column LIKE 'Hello%' OR column LIKE 'That%'</code>

This query will find records whose column values ​​match any specified pattern.

Example

Consider the following example query:

<code class="language-sql">SELECT * FROM table WHERE column LIKE 'Text%' OR column LIKE 'Link%' OR column LIKE 'Hello%' OR column LIKE '%World%'</code>

This query will find records whose column values ​​match any of the following patterns:

• Text, Textasd, Text hello
• Link2, Linkomg
• HelloWorld
• ThatWorldBusiness

Wait...

Note: It is important to use the % wildcard correctly to ensure that all matching patterns are captured.
