Pivoting string fields in SQL Server 2008 R2 -


i need create dataset based on 1 generated series of sql sub-queries. results of sub-queries can replicated using following code:

create table table1     (`stayid` varchar(3), `incidentorder` int, `txdetails` varchar(73)) ;  insert table1     (`stayid`, `incidentorder`, `txdetails`) values     ('ip1', 1, 'ward: a9999 - 01/01/2015 - 15:23'),     ('ip1', 2, 'consultant: joe bloggs specialty :geriatric medicine - 02/01/2015 - 08:17'),     ('ip1', 3, 'discharge - 06/02/2015 - 16:40'),     ('ip2', 1, 'consultant: joe bloggs - 01/01/2015 - 09:02'),     ('ip2', 2, 'consultant: joe bloggs specialty :geriatric medicine - 02/01/2015 - 12:56'),     ('ip2', 3, 'ward: a9999 - 02/01/2015 - 19:39'),     ('ip2', 4, 'consultant: joe bloggs - 05/01/2015 - 08:22'),     ('ip3', 1, 'ward: a9999 - 02/01/2015 - 04:58'),     ('ip3', 2, 'consultant: joe bloggs specialty :gastroenterology - 02/01/2015 - 07:27'),     ('ip3', 3, 'consultant: joe bloggs - 05/01/2015 - 09:06'),     ('ip3', 4, 'ward: a9999 consultant: joe bloggs - 05/01/2015 - 16:45'),     ('ip3', 5, 'ward: a9999 consultant: joe bloggs - 05/01/2015 - 17:10'),     ('ip3', 6, 'ward: a9999 - 05/01/2015 - 18:14') ;

i need produce results follows:

columns: stayid, tx1, tx2, tx3, tx., txn

with transferdetails being populated each matching stayid , txn column (based on incidentorder).

the incidentorder not fixed , 10, 30, or 1 each stayid in data set, static pivot not option.

i have tried (and failed) producing required output using pivot , hopeful here can help.

thanks in advance

check dynamic query,

declare @colname varchar(max),         @qry varchar(max)  select @colname = isnull(@colname + ',','') + quotename(incidentorder) (select distinct incidentorder table1) cols  set @qry = 'select stayid, ' + @colname + '             (                 select stayid, incidentorder, txdetails                   table1             ) tbl             pivot             (                 max(txdetails) incidentorder                 in (' + @colname + ')             )             pvt'  exec(@qry)
