ADO RDD xHarbour | Welcome back AHF. I am excited to have your expertise available again.
I like the COPY TO example. One concern I have is the HBRECNO field. I presume you need to first create the SQL table with the added HBRECNO field before running your code?
James |
ADO RDD xHarbour | James,
No thats done by adordd.
In ado_create the field defined as recno is taken care automatically so you dont need to care about it.
The field will be always created with the name defined as default or to that table in adordd sets.
If the field is defined already in the dbf structure and not as autoinc field it wil... |
ADO RDD xHarbour | AHF,
Thanks for that explanation.
I tried your COPY TO method but it still took 16 minutes and 42 seconds. So, it is not significantly faster that APPEND FROM.
I think the speed issue has to do with locking. One reason is that I found that you have to force locking on or the APPEND FROM will crash at some point (unl... |
ADO RDD xHarbour | To put this APPEND FROM speed issue in perspective, if you need to import 1 million records it will take:
1000000/26000 = 38 X 18 minutes = 692 minutes/million or 692/60 minutes = 11.5 hours.
If you rarely need to import records, then this is probably not a big issue. I do know some people on this forum have mentione... |

ADO RDD xHarbour | AHF,
The thought just came to me that the customers table in the ACCESS Northwind.mdb does not have the HBRECNO field (because it is a default file). Could that be the reason that the temp indexes aren't working?
James |
ADO RDD xHarbour | James,
Without some autoinc field defined as recno results are unpredictable.
It might be it. |
ADO RDD xHarbour | Antonio F,
OK, I exported the customer table from the SQL database to a DBF, dropped the table, then recreated the SQL table so the HBRECNO field would be created. And imported the records back in from the DBF. Then the temp index began working. Problem solved.
Thanks for your help.

I forgot to mention that an UPDATE forces the disk buffer to be written to disk, so this the reason the update is so slow. If there is only an UPDATE after 100 records (or even 500) there is still probably (depending on the buffer's size) only one disk write, thus the great increase in speed.

In adordd we cant control commit frequency, as far as I know, with :addnew method.

ADO RDD xHarbour | Kleyber,
Thanks.
You have tryadordd but be advise that I didnt test it myself with these last versions, but should be a good guide.
There arent any special features to show, it works just like dbcdx kind rdd.
The best way to test it is to upload your tables compile and link adordd and run it.
Please read 01_readme.p... |
ADO RDD xHarbour | Thank you for your effort Antonio,
I'll try it also as soon as possible. |
ADO RDD xHarbour | Antonio, this error comes on different places in the code of adordd.prg. I tested with access and mssql.
Error description: Error ADODB.Recordset/6 DISP_E_UNKNOWNNAME: OPEN

ADO RDD xHarbour | Gunther,
This routine returns the lastrec().
With access it can not error that because with engine = ACCESS its SELECT MAX--- you can check the code.
As I informed previously I only tried it with Access but mainly with MySql.
I suspect that with MsSql the syntax of SELECT ... FROM SCHEMA... its wrong.
Do you know ... |
ADO RDD xHarbour | Antonio, with Access i read this error:
Error description: Error ADODB.Recordset/6 DISP_E_UNKNOWNNAME: OPEN
Args:
[ 1] = C SELECT * FROM TABLE1 ORDER BY HBRECNO
[ 2] = O ADODB.Connection
[ 3] = N 2
[ 4] = N 3
[ 5] = N 0

ADO RDD xHarbour | Gunther,

What is your SET ADO CACHESIZE TO... ? |
ADO RDD xHarbour | Antonio, now i found that the .mdb is constructed but no tables inside!! -> Also the error comes from here.
I use this code:
[code=fw:3fpva3xa]<div class="fw" id="{CB}" style="font-family: monospace;">DbCreate<span style="color: #000000;">(</span><span style="color: #ff0000;">"table1;"</span>+cPath+<span style="col... |
ADO RDD xHarbour | Gunther,
Those are left overs from trials.
Take out ";cpath" you dot need it anymore. The database its auto created if not exist during connection.
In fact if you verify the table was created in the database indicated in SET ADO DEFAULT DATABASE...
Confirm? |
ADO RDD xHarbour | Antonio, sorry, no tables!
I test
[code=fw:1sqcu213]<div class="fw" id="{CB}" style="font-family: monospace;">DbCreate<span style="color: #000000;">(</span> <span style="color: #ff0000;">"table2;test2.mdb"</span>, ....<br />DbCreate<span style="color: #000000;">(</span> <span style="color: #ff0000;">"table2;tes... |
ADO RDD xHarbour | Gunther,
Do it just like in clipper DbCreate( "table2,{...)
Is SET ADO DEFAULT DATABASE TO TESTADORDD.MDB ? Isnt the table there instead ? |
ADO RDD xHarbour | Antonio, please see my earlier post!
All is ok now!
Thanks for your great work! |
