How Can I Perform Case-Sensitive Queries in MySQL?

Case Sensitivity in MySQL Queries

In MySQL, query operations typically disregard letter case by default. However, there may be instances where case-sensitive comparisons are necessary.

Querying for Exact Location Match

Consider the following query:

SELECT Seller FROM Table WHERE Location = 'San Jose'

By default, this query will retrieve sellers with locations matching both 'San Jose' and 'san jose'. To ensure only exact matches are returned, a case-sensitive query can be used.

Using the BINARY Operator

MySQL provides the BINARY operator, which enables byte-by-byte comparisons. This ensures that the query will differentiate between different letter cases.

The modified query to achieve case sensitivity:

SELECT Seller FROM Table WHERE BINARY Location = 'San Jose'

Now, this query will only return sellers with locations exactly matching 'San Jose', regardless of case.

Note: It's important to note that the BINARY operator should only be used when necessary, as it can affect query performance. For non-case-sensitive comparisons, the default query behavior should be sufficient.
