Binary data is not stored in the MS SQL Database

I'm trying to upload files to a SQL Server database with ObjectPAL but the binary data not being stored in the SQL Server database but in with Paradox  table this code works fine. I think that MS SQL is not recognizing the data for some reason. 

objectPal variable is binary and MSSQL field is varbinary(MAX)

............

fileDataBinary             ;Save file data 

endVar

.............

if fileData.readFromFile(selectedFile) then 

..........

TC_Attachments.edit()

TC_Attachments.insertRecord()

TC_Attachments.Social_Security_No  = "AXVD20"

TC_Attachments.File_Name_Native= fileName 

TC_Attachments.File_Size_Native = fileData.size() ;Store size in bytes

TC_Attachments.File_Attachment_Native = fileData           ;Store data in binary

TC_Attachments.Upload_Date   = datetime()

TC_Attachments.endEdit()
