Moving DBFCDX to MS SQL

[cdmmaui]

Hello Everyone,

I am moving DBFCDX to MS SQL and I was hoping to get some feedback on the best way to TOleAuto connection, recordset, open and data refresh

1. Is the best way to establish SQL connection and execute SQL statement

TRY
oSql:=TOleAuto():New("ADODB.Recordset")
CATCH
MsgInfo("It seems that your PC does not have MDAC installed OR MDAC is corrupted.")
RETURN (.F.)
END
MsgInfo( "ADODB.Recordset OK!")

// Set...
oSql:CursorType := 1 // opendkeyset
oSql:CursorLocation := 3 // local cache
oSql:LockType := 3 // lock opportunistic

// Set SQL string...
cSql := "SELECT * FROM SalesOrderHeader"
TRY
oSql:Open( cSql, 'Provider='+xPROVIDER+';Data Source='+xSOURCE+';Initial Catalog='+xCATALOG+';User Id='+xUSERID+';Password='+xPASSWORD )
CATCH oError
MsgWait("Failed to Connect to the Database")
RETURN (.F.)
END
MsgInfo( oSql:RecordCount )

2. Can I use same oSql to execute another SQL statement on another table?

3. How do I handle data refreshes from the SQL statement in item 1. ( "SELECT * FROM SalesOrderHeader" )

Thank you,

Yes, but you have to oSql:Close() first.

3. How do I handle data refreshes from the SQL statement in item 1. ( "SELECT * FROM SalesOrderHeader" )

It depends on the CursorType. Have a look at MSDN docs.

For the refresh you can use :

Code: Select all  Expand view

oSql:Requery()
