Here's a working query on any db

<pre><code>select distinct table_name,
 stuff((select ','+data_type
 from information_schema.columns b
 where b.table_name=a.table_name
 for xml path(''),type).value('.[1]','nvarchar(max)'),1,1,'') AS data_types,
 stuff((select ','+column_name
 from information_schema.columns b
 where b.table_name=a.table_name
 for xml path(''),type).value('.[1]','nvarchar(max)'),1,1,'') AS column_names
from information_schema.columns a
</code></pre>

And here is your query

<pre><code>select distinct FKTABLE_NAME,
 stuff((select ','+FKCOLUMN_NAME
 from tbl b
 where b.FKTABLE_NAME=a.FKTABLE_NAME
 for xml path(''),type).value('.[1]','nvarchar(max)'),1,1,'') AS FKCOLUMN_NAMES,
 stuff((select ','+PKCOLUMN_NAME
 from tbl b
 where b.FKTABLE_NAME=a.FKTABLE_NAME
 for xml path(''),type).value('.[1]','nvarchar(max)'),1,1,'') AS PKCOLUMN_NAMES
from tbl a
</code></pre>

blocks|key|1919820|text|与所有字符串聚合问题一样，我建议编写一个自定义聚合(我强烈建议使用clr聚合以获得最佳性能)，并编写如下查询|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1919821|select+fktablename,+stringAggregate(fkcolumnname),+stringAggregate(pkcolumnname)
group+by+

As with all string aggregation problems I advise writing a custom aggregate (and I STRONGLY advise using a clr aggregate for best performance) and write a query like this

<pre><code>select fktablename, stringAggregate(fkcolumnname), stringAggregate(pkcolumnname)
group by 
fktablename
</code></pre>

blocks|key|1919833|text|下面的SQL语句用于转换单行中的单列数据：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1919834|declare+@testdata+varchar(8000)

Below SQL statement is used for converting single column data in a single row:

<pre><code>declare @testdata varchar(8000)
set @testdata=''

select @testdata=@testdata+NAME+', ' from User where ID in('1','2','3','4','5')
print @testdata

select substring(@testdata,0,len(@testdata))
</code></pre>

In above the above example:

<ul>
<li>User is a table</li>
<li>NAME is column of user which data will be manuplate in row</li>
<li>ID is column of user</li>
</ul>

For reference see below link:

<a href="http://www.thedevheaven.com/2012/02/column-data-in-to-single-row-with-comma.html" rel="nofollow">http://www.thedevheaven.com/2012/02/column-data-in-to-single-row-with-comma.html</a>

I have a table with values as 

<pre><code>FKTABLE_NAME FKCOLUMN_NAME PKCOLUMN_NAME
table1 column1 column1
table1 column2 column2
table2 column1 column1
table2 column2 column2
</code></pre>

How I need to convert this into

<pre><code>FKTABLE_NAME FKCOLUMN_NAME PKCOLUMN_NAME

tablel1 column1,column2 column1,column2
table12 column1,column2 column1,column2
</code></pre>

Basically, I am trying to get the comma seperated columns group by the table name.

thanks
