There are several methods   If you want just the consolidated string value returned  this is a good quick and easy approach  DECLARE  combinedString VARCHAR MAX  SELECT  combinedString   COALESCE  combinedString               stringvalue FROM jira customfieldValue WHERE customfield   12534     AND ISSUE   19602  SELECT  combinedString as StringValue    Which will return your combined string   You can also try one of the XML methods e g    SELECT DISTINCT Issue  Customfield  StringValues FROM Jira customfieldvalue v1 CROSS APPLY   SELECT StringValues                      FROM jira customfieldvalue v2               WHERE v2 Customfield   v1 Customfield                    AND v2 Issue   v1 issue                ORDER BY ID                    FOR XML PATH        D   StringValues   WHERE customfield   12534     AND ISSUE   19602

Using MySQL inbuilt function group concat   will be a good choice for getting the desired result  The syntax will be -  SELECT group concat STRINGVALUE   FROM Jira customfieldvalue WHERE CUSTOMFIELD   12534 AND ISSUE   19602   Before you execute the above command make sure you increase the size of group concat max len else the the whole output may not fit in that cell   To set the value of group concat max len  execute the below command-  SET group concat max len   50000    You can change the value 50000 accordingly  you increase it to a higher value as required

I believe for databases which support listagg function  you can do   select id  issue  customfield  parentkey  listagg stingvalue       within group  order by id  from jira customfieldvalue where customfield   12534 and issue   19602 group by id  issue  customfield  parentkey

There s a convenient method for this in MySql called GROUP CONCAT  An equivalent for SQL Server doesn t exist  but you can write your own using the SQLCLR  Luckily someone already did that for you   Your query then turns into this  which btw is a much nicer syntax    SELECT CUSTOMFIELD  ISSUE  dbo GROUP CONCAT STRINGVALUE  FROM Jira customfieldvalue WHERE CUSTOMFIELD   12534 AND ISSUE   19602 GROUP BY CUSTOMFIELD  ISSUE   But please note that this method is good for at the most 100 rows within a group  Beyond that  you ll have major performance problems  SQLCLR aggregates have to serialize any intermediate results and that quickly piles up to quite a lot of work  Keep this in mind   Interestingly the FOR XML doesn t suffer from the same problem but instead uses that horrendous syntax

You can achieve this is to combine For XML Path and STUFF as follows   SELECT  STUFF           SELECT        StringValue         FROM Jira customfieldvalue         WHERE CUSTOMFIELD   12534         AND ISSUE   19602         FOR XML PATH                1  2            AS StringValue
