Inserting Signature byteStream to Database

Hello,

I'm trying to insert the signature bytestream into the database from the SignaturePad perspective component.
Unfortunately, I'm getting an error message. Please can anyone help? Here is my code:

mySignature = event.signatureFile.getBytes()

query = "INSERT INTO PhotoTable (photo) VALUES (?)"
args = [mySignature]
system.db.runPrepUpdate(query, args, "MyDBConn")

This is my table definition:

CREATE TABLE [dbo].[PhotoTable](
	[Id] [bigint] IDENTITY(1,1) NOT NULL,
	[photo] [varbinary](50) NULL
) ON [PRIMARY]
GO

and here is the error that I'm getting:

Getting some error on the prep update. I would make this as a named query and test with some dummy data if it inserts properly.

I tried inserting just value of 0 with the same query and it worked.

I suspect that there is something wrong with the datatype of the "mySignature" variable

ok, it's now resolved.

I had to increase the size in database
