Batch insert with TDateTime property, ORM, Zeos-Firebird

I faced a problem with batch inserting records, which have TDateTime field (Timestamp in Firebird):

Without TDateTime property inserting works fine. Inserting without batch also works.

At the same time, batch updating with the same data also works fine:

Re: Batch insert with TDateTime property, ORM, Zeos-Firebird

Normally, TSQLDBConnectionProperties.MultipleValuesInsert() is supposed to set the field type as TimeStamp in line 6157 of SynDB.pas.

Then, SynDBZeos should detect the ftDate field type, and call fStatement.SetTimestamp() as expected.

Could you please use the debugger to find out why it is not the case?

Re: Batch insert with TDateTime property, ORM, Zeos-Firebird

Trying to debug for a rather long time. Will continue doing that, just decided to share some new information. Maybe you'll have some idea and I would be able to stop breaking my mind wink

TSQLDBConnectionProperties.MultipleValuesInsert() never starts in my project.
Instead of it TSQLRestStorageExternal.InternalBatchStop by running fProperties.OnBatchInsert() goes to TSQLDBConnectionProperties.MultipleValuesInsertFirebird() procedure.
As far as I could see, LastUpdate field type (FieldTypes array) is founded to be correct: ftDate. Although in FieldValues I have the same ISO datetime value (don't know so far, whether it is good or not).

One more thing, which confuses me much. Rarely, during testing I get another error in my batch sending (without any code changing):

20191102 16074830 trace uNextDB.TNextDB(050b2a10) BatchSend {"TSQLRestBatch(04e2dcc0)":{"Count":2,"SizeBytes":1077}}

20191102 16074830 EXC   	EORMException {"Message":"TSQLRestStorageExternal.InternalBatchStop(TSQLPerson).BatchMethod=mNone"} [] at dc19e7

It is completely undetermined and can complain about other fields (Surname f.ex).

I guess I need to create a simpler testing project. Maybe there is some problem with my bigger project...

upd: using latest Zeos from master branch, now (587fa5e 2019-11-01)

Re: Batch insert with TDateTime property, ORM, Zeos-Firebird

Datetime field in insert batch is: '2019-11-02T05:55:51'
In Update batch is: '2019-11-02 06:03:28' without T

Re: Batch insert with TDateTime property, ORM, Zeos-Firebird

Yes, true. That's the point. As I supposing:
Batch is forming in JSON, where TDateTime value is in ISO format (with T). Then SQL should be transformed into external SQL and processed. But somehow it doesn't happen in my case with insert in a batch.
There are different ways of batch processing ways in TSQLRestServer.EngineBatchSend and other following methods and I hardly can understand the magic (so far at least). Will continue trying wink

Re: Batch insert with TDateTime property, ORM, Zeos-Firebird

Using TSQLDBConnectionProperties.MultipleValuesInsert() works fine, btw.
Tested that way:

procedure TSQLDBConnectionProperties.MultipleValuesInsertFirebird(
  Props: TSQLDBConnectionProperties; const TableName: RawUTF8;
  const FieldNames: TRawUTF8DynArray; const FieldTypes: TSQLDBFieldTypeArray;
  RowCount: integer; const FieldValues: TRawUTF8DynArrayDynArray);
var W: TTextWriter;
    maxf,sqllenwitoutvalues,sqllen,r,f: Integer;
begin
  MultipleValuesInsert(Props, TableName, FieldNames, FieldTypes, RowCount, FieldValues);
  Exit;

  maxf := length(FieldNames);     // e.g. 2 fields
  if (Props=nil) or (FieldNames=nil) or (TableName='') or (length(FieldValues)<>maxf) or
...

Result:

Re: Batch insert with TDateTime property, ORM, Zeos-Firebird

I ran several tests (for about 100K records) and I didn't find that MultipleValuesInsert is anyhow slower than MultipleValuesInsertFirebird for my project.
So if there an idea to purge MultipleValuesInsertFirebird will appear, I'm totally for it wink

Re: Batch insert with TDateTime property, ORM, Zeos-Firebird

Arnaud, could you confirm or disprove, please, that there is a problem with TSQLDBConnectionProperties.MultipleValuesInsertFirebird() exist?
I would like to know, which way I should close this issue for my project. Thanks!

Re: Batch insert with TDateTime property, ORM, Zeos-Firebird

I guess the correct way to handle this issue is to fix MultipleValuesInsertFirebird().
Please check https://synopse.info/fossil/info/3b3546d959

I think TSQLDBConnectionProperties.MultipleValuesInsertFirebird() will be noticeably faster than TSQLDBConnectionProperties.MultipleValuesInsert() only if ZEOS is not used.
In fact, Zeos appears to apply the same process than MultipleValuesInsertFirebird on its side.
