How To Concatenate Query Results in SQL Server(TSQL)

The other day I had to concatenate a query result. In this article, I’m going to tell you how to do this through an example.

Example:

Let’s create a table like below and add a few records into this table.

CREATE TABLE [dbo].[ConcatenateResultsExample](
[myString] [varchar](50) NULL
) ON [PRIMARY]
GO
INSERT INTO [dbo].[ConcatenateResultsExample] VALUES('1'),('2'),('3'),('4'),('4'),('5')

CREATE TABLE [dbo].[ConcatenateResultsExample](

[myString] [varchar](50) NULL

) ON [PRIMARY]

INSERT INTO [dbo].[ConcatenateResultsExample] VALUES('1'),('2'),('3'),('4'),('4'),('5')

If we want to read the data in this table, we will see the result as follows.

Select * FROM [dbo].[ConcatenateResultsExample]

1	Select * FROM [dbo].[ConcatenateResultsExample]

Let’s concatenate this result set. You can perform this operation with the help of the following script.

DECLARE @concatenatedresult varchar(50)
SET @concatenatedresult = ''
SELECT @concatenatedresult = @concatenatedresult + myString + ', '
FROM [dbo].[ConcatenateResultsExample]
SELECT @concatenatedresult;

DECLARE @concatenatedresult varchar(50)

SET @concatenatedresult = ''

SELECT @concatenatedresult = @concatenatedresult + myString + ', '

FROM [dbo].[ConcatenateResultsExample]

SELECT @concatenatedresult;
