I have the following connection string that works fine in ASP:

Code: Select all  Expand view

"Provider=sqloledb;Data Source=xxx.xxx.xxx.xxx;User Id=MyUserid;Password=MyPasswd"

How do I have to use it with ADORDD? I tried:

Code: Select all  Expand view

USE "MyTable" VIA "ADORDD" TABLE "MyTable" FROM "xxx.xxx.xxx.xxx" USER "MyUserid" PASSWORD "MyPasswd" SQL

and many other combinations without success (I get Open failed error).

Enrico,

You may modify adordd.ch and adordd.prg to accept a CONSTRING clause (or another name), and then from adordd.prg use your connection string as it is, i.e.:

USE "MyTable" VIA "ADORDD" CONSTRING "Provider=sqloledb;Data Source=xxx.xxx.xxx.xxx;User Id=MyUserid;Password=MyPasswd" ALIAS "MyAlias"

Ok, but I think it would be better if MSSQL support were built-in in standard ADORDD version, isn't it?

I sent you a private message this morning on the SQL index issue .. no luck.

I have been developing this app in parrallel using ado methods and adordd.. I think MS SQL and Oracle are a lot alike in that they really only use indexes if the execution plan will create a faster result .. I don't think MS SQL indexes are part of the SQL engine ADO can manipulate .

Let me know if I can help test further ..

As you may have seen from my last post .. I have been working in tandum with standard ADO and ADORDD for the MS SQL project.

This snipit of code works well for me .. indexes in MS SQL seem to be a bit 'sticky' as of yet .. I am sure Antonio will find a solution.

#INCLUDE "ADORDD.CH"

cFROM := "xxx"
cUSER := "xxxr"
cPSW := "xxx"
cDBF := "test"
cTABLE := "USERINFO"

TRY

SELECT 1
USE (AllTrim(cDbf)) VIA "ADORDD" TABLE AllTrim(cTable) SQL ;
FROM AllTrim(cFrom) USER AllTrim(cUser) PASSWORD AllTrim(cPsw)

SET INDEX to USERID // doesn't see

CATCH oERR
MsgInfo( "Error in Opening USERINFO table" )
oDlg:End()
RETURN(.F.)
END TRY

Enrico,

adordd.prg provides support for MSSQL:

Code: Select all  Expand view

      case aWAData[ WA_ENGINE ] == "SQL"
           aWAData[ WA_CONNECTION ]:Open( "Provider=SQLOLEDB;" + ;
                                          "server=" + aWAData[ WA_SERVER ] + ;
                                          ";database=" + aOpenInfo[ UR_OI_NAME ] + ;
                                          ";uid=" + aWAData[ WA_USERNAME ] + ;
                                          ";pwd=" + aWAData[ WA_PASSWORD ] )


But you have to provide the database name, server address, user and password, besides the table name too.

In your connection string there is no a database name

Rick,

I got your emails. Its better if we discuss the ADORDD here, so others can participate too.

> I don't think MS SQL indexes are part of the SQL engine ADO can manipulate

We have only tested Access and MySQL, so you are our official MsSQL tester

We assume that ADO provides a common interface for all databases engines, but there may be some differences between them (?)

[Antonio Linares]

Rick,

Please try this, after the USE ...:

MsgInfo( HB_AdoRddGetCatalog():Tables( cTableName ):Indexes:Count )

I just tried with

Code: Select all  Expand view

USE "DatabaseName" VIA "ADORDD" TABLE "TableName" FROM "IpAddress" USER "UserId" PASSWORD "Password" SQL

and it won't work anyway.

What am I missing?
