CREATEINSTREAM Function (BLOB)

  • 项目

Creates an InStream object for a binary large object (BLOB). This enables you to read data from the BLOB.

Syntax

  
Blob.CreateInStream(Stream[,TextEncoding.value])

Parameters

Blob
Type: Variable

The BLOB variable for which you are creating the InStream object.

Stream
Type: InStream

The InStream object type that has been created.

TextEncoding
Value: MsDos, UTF8, UTF16, or Windows

Optionally, you can specify the encoding on the stream. By specifying the text encoding, you ensure that all the language-specific characters are represented correctly in Dynamics NAV when you read data and write data. The following example illustrates how you can set the encoding to Windows when you create a stream for a BLOB field.

MyTable.MyBLOBfield.CREATEINSTREAM(MyStream, TextEncoding.WINDOWS)
