How do I make a SQL query not case-sensitive? ›

To do a case-insensitive comparison, use the ILIKE keyword; e.g., column ILIKE 'aBc' and column ILIKE 'ABC' both return TRUE for 'abc' . In contrast, MySQL and MS SQL Server have case-insensitive behaviors by default. This means WHERE column = 'abc' returns TRUE for e.g., 'abc' , 'ABC' , or 'aBc' .

MySQL will look for objects names in with the exact case sensitivity as written in the query. You can turn off table name case sensitivity in MySQL by setting the parameter lower_case_table_names to 1. Column, index, stored routine, event names, and column aliases aren't case sensitive on either platform.

To write a case-sensitive search in SQL Server, don't use UPPER or LOWER functions around the column to filter. Instead, use the COLLATE keyword with a case-sensitive collation followed by the comparison.

However, you can use the ILIKE operator instead of LIKE to perform a case-insensitive search. BigQuery: The LIKE operator is case-sensitive in BigQuery. However, you can use the REGEXP_CONTAINS function to perform a case-insensitive search using regular expressions.

Dynamic data masking helps prevent unauthorized access to sensitive data by enabling customers to specify how much sensitive data to reveal with minimal effect on the application layer. DDM can be configured on designated database fields to hide sensitive data in the result sets of queries.

Using LIKE clause to do Case-Insensitive Search in a Column

SELECT * FROM Users WHERE name LIKE 'john'; This query will return all customers whose name is “john”. Since it is a case-insensitive search, the query returns multiple rows.

SQL Server is, by default case insensitive; however, it is possible to create a case sensitive SQL Server database and even to make specific table columns case sensitive. The way to determine a database or database object is by checking its “COLLATION” property and look for “CI” or “CS” in the result.

Are SQL Keywords Case-Sensitive? The straightforward answer is that SQL is generally case-insensitive. That means you could write your SQL keywords in any case and the database engine will interpret them correctly. All of these will produce the same result, regardless of the case used in the keywords.

Further, we can make the search and condition specifying to ignore the case in SQL using the LOWER() and UPPER() functions while collation contains CS.

If you want to use a case-insensitive Oracle database with Service Manager instead of using the sqlupper:1 solution, you must meet the following requirements: NLS_SORT=BINARY_CI and NLS_COMP=LINGUISTIC must be set in the Oracle instance level.

How do I sort case-sensitive in SQL? ›

Sorting Data by Case Sensitivity

By default, the ORDER BY clause performs a case-insensitive sort. However, if you want to perform a case-sensitive sort, you can use the COLLATE keyword followed by a case-sensitive collation name.

Access normally performs case-insensitive string comparisons.

You can disable table name case sensitivity in MySQL by setting the parameter lower_case_table_names to 1. Column, index, stored routine, event names, and column aliases are not case sensitive on either platform.

To make grep case insensitive, all you have to do is add an -i or —ignore-case flag. As always, you can type man grep into your command line to get the official documentation for grep and all its flags and parameters. If you want to learn more, check out this page for more information on the grep command.

The LOWER() function converts a string to lower-case.

SQL Server is, by default case insensitive; however, it is possible to create a case sensitive SQL Server database and even to make specific table columns case sensitive. The way to determine a database or database object is by checking its “COLLATION” property and look for “CI” or “CS” in the result.

All told, both CASE and IIF get the same job done, but if given the choice, IIF will generally be much simpler to use.
