How to compare or filter data based on column having byte datatype in Teradata i.e binary string data

Teradata: Byte Comparing

Following datatypes can be used to store 'Binary String Data'
Example: Binary String Data
00003b77

Sample Table : Creating a table with Byte data type
CREATE MULTISET VOLATILE TABLE byte_users
( 
  id      INTEGER,
  userId  Byte(4)
)
ON COMMIT PRESERVE ROWS;

Data Population : Inserting couple of records in the table for testing query
INSERT INTO byte_users(1, '00003b77'XB);
INSERT INTO byte_users(2, '00007b23'XB);

Data View : Checking data in the byte_users table
SELECT * FROM byte_users;

Output:
id  userId
1   00003b77  
2   00007b23 

Normal Querying 1: Trying to find data based on the byte characters but it will result in error.
SELECT * FROM byte_users WHERE userId='00003b77';

Output:
*** Failure 3640 Comparing BYTE data in column userId with other types is illegal.

Normal Querying 2: Trying to find data by casting characters to byte but it will result in error.
SELECT * FROM byte_users WHERE userId=CAST('00003b77' AS BYTE(4));

Output:
*** Failure 3532 Conversion between BYTE data and other types is illegal.


How to query columns containing byte data?

Approach: Suffix XB at the end of the string,For example
SELECT * FROM byte_users WHERE userId='00003b77'XB;

Output:
id  userId
1   00003b77 

What does 'XB' denotes which is used in the query?
'x' indicates that the value of literal is hexadecimal and 'b' indicates that the datatype is byte.
