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.
