The following examples will show a detailed description of how to combine multiple rows into one. How to Concatenate Multiple Rows into a Single Row in Microsoft SQL Server?Ī rollup in data from a single row is sometimes necessary in order to concatenate data reports to different systems. The FOR XML PATH option will return the results to an XML format that puts the entire data into one row and a column. Using the normal query as follows gives us the following set of results. This option generates one element per return row. So we end up with the output of KEITHSTEFAN.įOR XML Clause for SQL Server SELECT Statementįor XML clause returns results from querying SQL as XML. We are looking for the first out of list. In our example we have the following strings: KEITHSTEFAN EUDURARD BRAD. Here is a sample of how to execute an STUFF command. STUFF(character expression, begin, length, replacingwith_expression ): This allows us to add, modify, or remove a certain character.

How can we combine rows with strings using the FOR XML PATH function of select queries in XML? The XML PATH methods are compatible with SQL Server version 2005 or higher. Then a stored process can be used to execute these operations to retrieve the concatenated string.Ĭhoose country names on the application. It's not necessary to worry about trailing commas. You just need to add the COALESTES in your variable name. This COALCESCE method may work for SQL Server versions 2007 or later. You may combine rows with strings by using COALESCE. SELECT GROUP_CONCAT(interest ORDER BY interest ASC SEPARATOR ', ') as interests FROM user_interests WHERE user_id = 5 The above example can be altered as follows to order the interests alphabetically: The GROUP_CONCAT can also define an order of the concatenation. SELECT GROUP_CONCAT(interest SEPARATOR ', ') as interests FROM user_interests WHERE user_id = 5 The above query would be altered as follows: Now, what if I wanted to only return one row with all of the interests? This can be achieved with the MySQL GROUP_CONCAT function. SELECT interest FROM user_interests WHERE user_id = 5 Let's start with the most simple techniques.Ī typical SQL query to retrieve these values would be done as follows: Concatenating rows in strings is possible by many different approaches.
