Say I have 3 columns: 1st name, middle name and last name. How do I merge the 3 columns into one column yet separate the content with commas?

Thanks. We'll let you know when a new response is added.

SQL Server doesn’t have the STRIP and CONCATINATION functions which were mentioned in the prior version of the answer.

You use the + sign to join the strings together, something like this.

<pre>SELECT FirstName + ', ' + CASE WHEN MiddleName IS NULL THEN '' ELSE MiddleName + ', ' END + LastName
FROM YourTable</pre>

I wrapped the MiddleName column within a CASE statement so that if it’s NULL it leaves the middle name out. If you want the blank field if the MiddleName is NULL then you’ll want something like this.

<pre>SELECT FirstName + ', ' + ISNULL(MiddleName) + ', ' + LastName
FROM YourTable</pre>

Tiny modification use an As to give column name-

<pre>SELECT (FirstName + ', ' + ISNULL(MiddleName) + ', ' + LastName) as FullName
FROM YourTable</pre>
