Hi aehimself,

In your last version of ZMemTable, empty cells are filled with zeros for numeric fields and with data from an
adjacent cell for string fields(after SaveSoFile-LoadFromFile)

Hi aehimself, I guess you're wrong about the ControlsCodePage. See how your extended example works: uses ...ZDatasetUtils... procedure TForm1.Button12Click(Sender: TObject); var ms:TMemoryStream; begin ZMemTable2.ControlsCodePage:=cCP_UTF16; ZMemTable2.Close; ZMemTable2.FieldDefs.Clear; ZMemTable2.F...

Hi aehimself, 1. None of my tables exceed 100MB. 2. In versions from svn this error also occurs in D10.3.3-Win32 and in Win64 it does not want to load from a file. 3. I meant the distinction between cCP_UTF16, cDynamic, cGET_ACP, cCP_UTF8 which produce different streams and files 4. Currently for D1...

Hi aehimself, Jan, Duplicate SaveToStream and LoadFromStream in svn7702. I still have 'Stream read error' in DXE2-Win32. For example, in such a table FB2.5 (100000 Records): SET SQL DIALECT 3; CREATE TABLE ELEMENTY100 ( NRELEMENTU INTEGER NOT NULL, NRKON INTEGER, NRDOK INTEGER, NRFRAGDOK INTEGER, NA...

Hi aehimself,

I noticed (in DXE2-Win32) that two errors appear with LoadFromFile: 'Stream read error' and 'Out of memory' depending on TMemTable - ControlCodePage cCP_UTF16, cDynamic, cGET_ACP.

ADD: I think the encoding information should be saved and used in stream and file?

Hi aehimself, Jan, This could be a question of new field types in D2006, D2007 and DXE2 compared to D7?: procedure TZAbstractRODataset.CheckFieldCompatibility(Field: TField; AFieldDef: TFieldDef); const {EH: hint all commented types are the fields the RowAccessor can't handle -> avoid stack killing ...

Hi aehimself, Still "Stream read error" reading from disk Delphi XE2-Win32. I use this method: I am connecting to a database (right now Firebird) with a lot of different tables. It clones them sequentially from ZTable to ZMemTable, writing to and reading from disk. As for the size, the tab...

Hi aehimself, It seems to compile in D2006 and DX2 but the SaveToFile file is 2 times larger and with LoadFromFile it gets 'Stream read error'. If Self.Fields[b] Is TBlobField Then Begin ms := TMemoryStream.Create; Try ms.CopyFrom(AStream, ReadInt); <<<<<<<<<<<<<================= AFTER THIS LINE ms....

Hi aehimself,

For both Delphi2006 and Delphi DX2:

[DCC Error] ZMemTable.pas(681): E2008 Incompatible types -- AStream.Write(buf^, Length(buf));

Michał

Hi aehimself, For Delphi2006: [Pascal Error] ZMemTable.pas(544): E2003 Undeclared identifier: 'ReadData' [Pascal Error] ZMemTable.pas(674): E2003 Undeclared identifier: 'WriteData' [Pascal Error] ZMemTable.pas(715): E2035 Not enough actual parameters -- AStream.CopyFrom(ms); [Pascal Error] ZMemTable...

Hi aehimself, Jan,

Maybe to adopt the 'kjteng' version to anything ?!?

Michał

Hi kjteng ,

For me it works on:
Lazarus 2.0.8-Win32,
Lazarus 2.0.12-Win64,
and Lazarus 2.2RC2(FPC 3.2.2)-Win64(Win11),
Delphi 2006,
but creates larger files that are not compatible with aehimself version for Delphi.

Michał

Records.
But you threw up an even more interesting idea of extracting specific records from the indicated fields.
Such a microSQL.

Michał

Hi ashimself,

The procedure "SaveToFile from i to j" and "MergeFromFile from i to j" with and without fielddefs would be handy.

Michał

Hi aehimself,

Now it runs in D10.3.3 Win32 / Win64 and loads data from each other
