Hello everyone,
for the procedures IUtil_loadBlobPtr & iUtil_dumpBlobPtr what type of
field is provided? BFile ??
May be I do not understand your question.
Apologies, I badly speak in English.
I'm also not native Enlish speaker...
In Firebird.pas, there are two procedures:
1) IUtil_loadBlobPtr = procedure (this: IUtil; status: IStatus; blobId:
ISC_QUADPtr; att: IAttachment; tra: ITransaction; file_: PAnsiChar; txt:
Boolean); cdecl;
2) IUtil_dumpBlobPtr = procedure (this: IUtil; status: IStatus; blobId:
ISC_QUADPtr; att: IAttachment; tra: ITransaction; file_: PAnsiChar; txt:
Boolean); cdecl;
Having a "file_: PAnsiChar" parameter and another "txt: boolean" which suggests
that there are plans to load and unload files external to Firebird.
My question was: Is there a type "external_File" for example: SQL_BFile = 32767
which would be missing in the Firebird.pas file?
Or if not, what is it used for?
Methods loadBlob/dumpBlob of Util interface (what you mention are not
procedures, just pascal analogue of C typedef) are used at client side
(certainly embedded case works too) to manipulate blobs - load data from
file to blob or store blob data in a file. Parameter "file_: PAnsiChar"
is a name of that file. Boolean txt defines should binary or text more
be used when working with that file. And yes - that files are sooner of
all "external to Firebird".
This methids have nothing to do with SQL data types, therefore nothing
like SQL_BFile is present.
