READ Function (BigText)

Type: Boolean

This optional return value specifies whether the read transaction was successful.

To delete the content in a BigText variable use the CLEAR function.

CLEAR(BigText)

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.

EmployeeRec.FIND('-');
EmployeeRec.CALCFIELDS(Picture);
EmployeeRec.Picture.CREATEINSTREAM(Istream);
Bstr.READ(Istream);

You 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.
