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

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

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

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

1. Click Cancel in Connect to Server Dialog
2. Click New Query which will bring up the new connection dialog.
3. Enter your credentials. By default, you will connect to Master database. If you want to connect to specific database, click options and enter the database name. Please be aware that USE is not supported.
4. Now click Connect and you will get an error “Unable to apply connection settings. The detailed error message is: ‘ANSI_NULLS’ is not a recognized SET option. “
5. Click Ok.

SQL convert string ‘mmddyy’ to date time format

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′)
