we have been provided with a data dump of a postgre sql table into a .psv doc

the data holds informatin on images and the actual image is stored as binary. Now when you open this doc to look at the information i want to see how it compared to that of the data that would be stored in an sql image field.

the reason beimng in that the rouine i have that should open the image from the binary data and save it is failing in the previous errors i have reported and i can only put it down to how the data has been passed to us?

if that makes any sense at all

why can't you just do an import into sql server without going code side?

also are you sure you mean a psv or csv?

yes, its a pipe seperated value list

We have gone that route as we are still not sure if the data is correct. Would opening the data as text change the way that the binary information is displayed?

opening it up wouldn't do anything, as long as you don't save it

have you tried to import inside management studio specifying the pipe, or doing something like this?

sql Syntax (Toggle Plain Text) 
  1. BULK INSERT MyTableName
  2.     FROM 'c:\mydata.psv' 
  3.     WITH 
  4.     ( 
  5.         FIELDTERMINATOR = '|', 
  6.         ROWTERMINATOR = '\n' 
  7.     )

i've found out the reason - the data i have is in standard escape format and of course i need to convert this back to its binary equivilent.

Do you know of any built in methods that will take this text and convert it back to binary in either vb or c .net

the management tool you need for the import is just sql management studio or even run it through code
did you try the bulk insert?

escape format meaning?

Dont have access to SQL server at the moment and not sure if it would work with the sql express?

the data that has been provided is a table dump of a postgre sql table and the format is plain and uses standard escape sequence similiar to c or perl.

Now i need to convert that back to its binary equivilent.

are you meaning all your double backslashes?

just run a replace on your escaped characters

ASP.NET Syntax (Toggle Plain Text) 
  1. Dim fileAsString As String = myString.Replace("\\", "\")
  2.  

i think this is how with vb, more familiar with csharp
