ADO RDD xHarbour

[dutch]

Dear Antonio,

Thank you for your help.

What do you mean open record ?

I mean open table with all records.

[AHF]

Lucas and Dutch,

Please remember that only the number of records its not enough.

The recsize x nrecords (although in SQL its indicative) its what matters mainly on WAN as this represents the bytes number bring across the cable.

Can you check that?

I try to create view from 2 table as below

Code: Select all  Expand view

cCreateViewSql := "CREATE VIEW TBLGST AS SELECT CCRTBL.TBL_RMNO, CCRTBL.TBL_LAST, CCRTBL.TBL_FIRST, CCRTBL.TBL_ARR, CCRTBL.TBL_DEP,  CCRGST.GST_LAST FROM CCRTBL INNER JOIN CCRGST ON CCRTBL.TBL_GSTNO=CCRGST.GST_INTNO"
hb_GetAdoConnection():Execute(cCreateViewSql)

But got an error as

Code: Select all  Expand view

Description : Error ADODB.Connection/0  S_OK: EXECUTE
   Args:
     [   1] = C   CREATE VIEW TBLGST AS SELECT CCRTBL.TBL_RMNO, CCRTBL.TBL_LAST, CCRTBL.TBL_FIRST, CCRTBL.TBL_ARR, CCRTBL.TBL_DEP,  CCRGST.GST_LAST FROM CCRTBL INNER JOIN CCRGST ON CCRTBL.TBL_GSTNO=CCRGST.GST_INTNO

Dutch,

Please remember that without any autoinc field it will not navigate correctly so you must include that field always.
I dont think you can join with different field names.

CCRTBL.TBL_GSTNO=CCRGST.GST_INTNO"

Dear Antonio,

The problem is my misunderstood. The VIEW has created but I will recreate it then it got error. I have to DROP VIEW before CREATE VIEW, if exist.
But it still take long time to CREATE VIEW. After reuse view, it is quite fast.

Regards,
Dutch

[AHF]

Dutch,

I think you should only need to create view once.
Then simply use it as any other table.
I think View is kept updated by the server.

Is It Working with MariaDB ?

[AHF]

Vilian,

Never tried it.

Can you try to use MYSQL engine at ADORDD and at the Mysql ODBC set it up to connect to MariaDb?

I think the connection string its the same but if not it should be very easy to add support for it in ADORDD.

You are doing an excellent work, congratulations!

I am trying to compile the ADORDD.PRG but I am getting the following "unresolved externals" (see below).

I was using the standard buildx.bat program but then I found the functions in xHarbour\libs\rdds.lib and added this lib to the buildx.bat but the same unresolved externals are still showing up.

buildx.bat
...
echo %hdirl%\rdds.lib + >> b32.bc

Maybe I am also missing a CH file?

How can I confirm that the RDDS.LIB is getting linked in?

Regards,
James
