CONCAT() Function in SQL Server
- Combine two strings as follows: CONCAT(‘W3Schools’, ‘.com’); SELECT CONCAT(‘W3Schools’, ‘.com’); SELECT CONCAT(‘W3School
- Combine the following three strings: CONCAT(‘SQL’, ‘is’, ‘fun!’); SELECT CONCAT(‘SQL’, ‘is’, ‘fun!’);

So, how can I join two SQL columns together?
Remove the * from your query and replace it with specific column names, as seen below: CONCAT(FIRSTNAME, ‘,’, LASTNAME) AS FIRSTNAME FROM ‘customer’; SELECT SOME OTHER COLUMN, CONCAT(FIRSTNAME, ‘,’, LASTNAME) AS FIRSTNAME FROM ‘customer’; Using * indicates that you want all of the table’s columns in your results. * will also include FIRSTNAME in your case.
Also, what is the SQL concatenation operator? Concatenation Operator is a command that joins two strings together.

In SQL, how can I concatenate records into a single column?
COALESCE is a technique for concatenating rows into a single string. SQL Server versions 2008 and above support the COALESCE technique. Simply define a varchar variable, concatenate the variable with a comma and the column within the coalesce, then assign the COALESCE to the variable.
