How Can I Perform Case-Insensitive Searches in SQL Server WHERE Clauses?

Ignoring Case Sensitivity in SQL Server WHERE clauses

To ensure that SQL queries ignore case in a WHERE clause, you need to pay attention to the database's string comparison configuration.

In the default setup, SQL Server databases configure string comparisons to be case-insensitive. However, if this setting has been altered using an alternate collation, you may need to specify a specific collation within your query. To do this, use the following syntax:

SELECT * FROM myTable WHERE myField = 'sOmeVal' COLLATE collation_name

The collation_name parameter defines the collation rules to be applied. For example, the following query ignores case sensitivity using the SQL_Latin1_General_CP1_CI_AS collation:

SELECT * FROM myTable WHERE myField = 'sOmeVal' COLLATE SQL_Latin1_General_CP1_CI_AS

It's important to note that the specific collation used will depend on the language and character set requirements of your data. Consult the Microsoft documentation for a comprehensive list of available collations.
