Al final de AdoRdd.prg hay una serie de funciones de FWH repetidas, que hay que eliminar.

Gracias por todo Antonio

I can not use hb_AdoUpload () shows the error in this line

Error DBCMD/1015 Argument error: DBUSEAREA
Stack Calls
===========
Called from: => DBUSEAREA( 0 )
Called from: D:\ADVRDD\PRG\CLASSES\adordd.prg => HB_ADOUPLOAD( 6394 )

calling program is in this way.
hb_AdoUpload ("D:\ADVSYS\DATA\", "DBFCDX", "MYSQL" .F.)

Thank you buddy, no reference to the problem.

I already downloaded the files, the problem is I can not do the conversion of the .dbf files to SQL

When I open big tables several times during app execution doesn't this lead to
out of memory or very slow opening of that table?

Adordd builds each table recordset only once.
If your table recordsets have million of records you will need enough memory for it and it can easily
reach some hundred MB or more.
When you open that table again the memory consumption its minimum as adordd clones that table set, which
means a kind of pointer to previous open recordset being extremely fast opening it again and very
low on memory use.

I am not clear on this. If every user has their own copy of all the databases in memory, then how do those databases get updated in real time when other users change them? If this doesn't happen, then how can this design be useful?

Aferra,

hb_AdoUpload ("D:\ADVSYS\DATA\", "DBFCDX", "MYSQL" .F.)

You are missing a comma before the last parameter. It should be:

hb_AdoUpload ("D:\ADVSYS\DATA\", "DBFCDX", "MYSQL", .F.)

James

Thanks James

still gives the error

Arerra,

The error message you posted before is occurring in the second line here (6394 in ADORDD.PRG):

if lOverWrite
hb_adoRddDrop( oCn, cBaseDir + aFile[ F_NAME ], , , DBEngine ) // erroring here
endif

But since you are passing .f. for lOverwrite, that line is not being executed, so it must be showing a different error message now. Please post the new error message.

James

Thank´s James

after thinking a lot, put this information in the main.prg and oh yes right gave the upload.

REQUEST DBFNTX
REQUEST DBFDBT

REQUEST DBFCDX
REQUEST DBFFPT

REQUEST ORDKEYNO
REQUEST ORDKEYCOUNT
REQUEST ORDKEYGOTO

REQUEST DESCEND

thank you for your attention

Aferra,

Thanks for posting your solution. I am going to put that in my notes.

Temporary Indexes

From the manual:

Indicates the names used for temporary files at SQL level.
It must start by TMP or TEMP but can be "TMPROGER"
These temporary files are mainly used for temporary indexes created in the SQL server as TEMPORARY and automatically destroyed after connection ends.

I am not sure what the above means.

I have a program that generates unique filenames for temp indexes, based on what existing temp names already exist. So, there is no way to know what those filenames will be until the program is running.

It is not clear to me if the TMP and TEMP are just prefixes for filenames (like TEMP001.CDX) or if that is the complete filename. Or, do I have to specify all of the exact filenames that will be used for temp indexes? When you have 5-10 users that all have to generate multiple temp indexes, I'm not sure how exact filenames can be known before compiling the program.

Any hints on how I can resolve this will be appreciated.
