MySQL String Concatenation: Unraveling the Operator

In the realm of database management, the ability to concatenate strings is a crucial task. For MySQL users, the question arises: "Which operator should I use to concatenate strings?"

In standard SQL, the pipe operator "||" is widely utilized for string concatenation. However, in MySQL, its usage requires a specific configuration. By setting "sql_mode" to 'PIPES_AS_CONCAT' or 'ANSI', you can activate the pipe operator's concatenation functionality.

For instance, the following code demonstrates the use of the pipe operator for concatenation:

SET sql_mode='PIPES_AS_CONCAT';
SELECT 'vend_name' || ' (' || 'vend_country' || ')'
FROM Vendors
ORDER BY vend_name;

By enabling the pipe operator, you gain access to a powerful concatenation tool that aligns with SQL standards. Remember to set the appropriate "sql_mode" value to unlock its full potential in MySQL.
