Example
This example shows how to stream a BigText that is stored as a BLOB in a table to a BigText variable.
This example requires that you define the following variables.
Variable | DataType | Subtype |
---|---|---|
Bstr | BigText | Not applicable |
EmployeeRec | Record | Employee |
Istream | InStream | Not applicable |
Copy Code | |
---|---|
EmployeeRec.FIND('-'); EmployeeRec.CALCFIELDS(Picture); EmployeeRec.Picture.CREATEINSTREAM(Istream); Bstr.READ(Istream); |
Use the CALCFIELDS Function (Record) to calculate the BlobField. A BlobField is a binary large object (maximum size 2 GB) and must be calculated if you want to use it in C/AL or display it in the application.
