how to search for exact string in mysql

Question

I\'m trying to search for an exact match of a string in mysql. The string is \'nrew\'. But when I do the queries below, I still get a result:

SELECT UserID F         


        

Answer 1

SELECT UserID FROM sys_users WHERE BINARY UserID='NREW'

Answer 2

One method is to use LIKE BINARY instead of =:

SELECT UserID FROM sys_users WHERE UserID LIKE BINARY 'nrew';

Answer 3

The default collation which MySQL uses to make comparisons is case insensitive. You need to specify a case sensitive collation or binary. You can either do this when creating the column, or in the query.

For example:

SELECT UserID FROM sys_users WHERE UserID='NREW' COLLATE latin1_bin

The proper collation depends on your character set. For latin1, the default, you can use latin1_bin. For utf8, utf8_bin.

Answer 4

You can use keyword Binary,

SELECT UserID FROM sys_users WHERE BINARY UserID='nrew'

Answer 5

Give this is try: http://www.devx.com/tips/Tip/13043

Select UserID from sys_users where convert(varbinary, UserID) = convert(varbinary, 'NREW') 

Or try COLLATE
