DataBinding: ‘System.Data.DataRowView’ does not contain a property with the name when using ImportRow(row)

bensdigital — Wed, 12 Jan 2011 18:18:36 +0000

issue: when try to bind or access the data colum from the datatable (from ImportRow method)

DataTable dTable = datatablesource //sql fetch DataTable dTableFilter = new DataTable();


for (int i = 0; i < dTable.Rows.Count; ++i)

{

                        dTableFilter.ImportRow(dTable.Rows[i]);

}
//then
            for (int i = 0; i < dTableFilter.Rows.Count; i++)

            {

lblRet.Text += " " + dTableFilter.Rows[i]["columnname"].ToString(); // produce following error }
error: DataBinding: ‘System.Data.DataRowView’ does not contain a property with the name “columname”

solution: make sure you clone the structure of the schema of the old datatable

e.g. before the importrow for loop
put: dTableFilter = dTable.Clone(); // clone the structure & schema

Unpack the packed COBOL COMP-3 Field in SAS w/ S370FPDw

bensdigital — Wed, 17 Feb 2010 16:20:02 +0000

problem:

DSN w/ Date field is packed w/ COBOL COMP-3

request:

read and unpack the date field in SAS

solution:

use data format: S370FPDw (where w is packed length for the field)

e.g.

for a packed field PIC 9(08) COMP-3 at position 200 total length for the date is 8 and packed length is 5

to read from DSN:

INPUT @200 testDate S370FPD5

to write to DSN
PUT @200 testDate $8.

SSMS Connection to SQL Azure

bensdigital — Tue, 01 Sep 2009 20:18:22 +0000

Please be aware that SSMS is not supported with SQL Azure yet. However, you can use the following workaround for the time being:

SQL convert string ‘mmddyy’ to date time format

bensdigital — Wed, 15 Jul 2009 18:45:32 +0000

1) T-SQL scalar function
CREATE FUNCTION DBO.[format_mmddyy_date] (@mmddyy_value varchar(6)) returns smalldatetime
as
begin
declare @return_value smalldatetime
set @return_value =(select CAST(
substring(Right(’000000′ + convert(varchar(6),@mmddyy_value),6),1,2)
+’/'+substring(Right(’000000′ + convert(varchar(6),@mmddyy_value),6),3,2)
+’/'+substring(Right(’000000′ + convert(varchar(6),@mmddyy_value),6),5,2)
as smalldatetime))
return @return_value
end

2) SQL Select statement
select CAST(
substring(Right(’000000′ + convert(varchar(6),@mmddyy_value),6),1,2)
+’/'+substring(Right(’000000′ + convert(varchar(6),@mmddyy_value),6),3,2)
+’/'+substring(Right(’000000′ + convert(varchar(6),@mmddyy_value),6),5,2)
as smalldatetime)

*replace the @mmddyy_value w/ your variable, column or string (e.g ’071509′)
