SQL Query Returns System.Byte[] error for field


When I try to run my SQL query in Nintex I get the system.byte error for the "EventLongDescritpion" field.  The field is a Varbinary field and has a character maximum length of -1.

Here is my connection string:

Data Source=*******;Initial Catalog=AccidentsAndIncidents;Persist Security Info=True;User ID=*****;Password=*******

Select statement:

Select Closed, EventTimestamp, BaseLocationName, IncidentNumber, Incident_PK, ReportingPersonName, EventDescriptionlong, Eventtypes
From IncidentView
Where Closed = 'false' AND GETDATE() > dateadd(dd,30, eventtimestamp) AND WorldWideUnit = 'NAIG USA'

Any help would be greatly appreciated!!

id change the type in that table from byte to varchar(max) just too see if that solves the issue
let us know if that solves it

if it does fix it
determine what the max should be obviously byte is too short for the characters in that field

Thanks for your response!

Not sure If I have that ability I will have to check with my IT dept.  Can it be fixed in by connection string or select statement?

I would do the some.
other than that, you would have to convert the binary array into some text, for example if the encoding is UTF8:
string yourtext = Encoding.UTF8.GetString( yourByteArray );

I do not belive the connection string has anything to do with it..
if you have access to SQL server management stuido you can change it very easily
1.click the + sign next to the database
2. click the+ sign on table folder
3. right click the table in question and choose design
4. change the datatype with the dropdown from byte to varchar

the some => the same
a simple query to do this would be

alter table  table1 alter column EventDescriptionlong VARCHAR(200)

to change it back

alter table  table1 alter column EventDescriptionlong byte

Thanks all for your responses.  I will check tomorrow to see if it works.
Hello Everyone,

Another option if access to the database instance is not available would be to convert the varbinary to nvarchar with formatting  (if the string is a hexidecimal).

give this a shot if you cant gain access to the database via ssms

CONVERT(NVARCHAR(max), EventDescriptionlong, 1) AS EventDescriptionlong

Open in new window

it can be used in a T-SQL query.

for more information about CONVERT and styles
