SQL Server function for joining string values


Updated: 14 December 2009

Use JOINSTR_q to concatenate the text from multiple rows in a table.
SELECT [wctString].[wct].[JOINSTR_q] (
   <@Separator, nvarchar(4000),>
 ,<@MaxItems, int,>
 ,<@Values_RangeQuery, nvarchar(4000),>)
is the text value to be used to connect the text to be concatenated. The @Separator argument can be of data types that are implicitly convertible to nvarchar or ntext.
is the maximum number of items to be included in the resultant text. The @MaxItems argument can be of data types that are implicitly convertible to int.
the select statement, as text, used to determine the text to be used in the JOINSTR_q.
Return Types
·         For simpler queries, consider using the JOINSTR function.
For this example, we have loaded up the Gettysburg Address into a table and we are going to use JOINSTR_q to put it back together by paragraph. You can find the data here.
    ' ',
    'Select b.word
    from Docs b
    where b.docname = ' + wct.QUOTES(a.docname) + ' and b.parano = ' + wct.QUOTES(a.parano))
where a.docname Like 'Gettysburg%'
Group by A.Parano, a.docname
order by parano
This produces the following result
Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal. 
Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. 
But, in a larger sense, we can not dedicate—we can not consecrate—we can not hallow—this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us—that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion—that we here highly resolve that these dead shall not have died in vain—that this nation, under God, shall have a new birth of freedom—and that government of the people, by the people, for the people, shall not perish from the earth.
