Can anybody give tell me or point me to the basic connection method please. Do I need any ODBC settings? In which case how do I set these up and how do I use them in Delphi? I see in ADOConnection there is a ConnectionString. Do I simply point this at the database on the server? If not then what? I see that ADOQuery has a Connection (OK) but then it also has a ConnectionString. What would this be used for? Where does ADODataSet fit in? Is it the equivelent of a ClientDataSet? shoudl it be used? is it to be avoided? I assume ADOTable is the equivelent of a Table and should be avoided at all cost! Help on any of thiese points would be much appreciated.

Just one final point I forgot to mention, the database is on a server. How do I point to the server? I assume it is somthing to do wht then "Provider=SQLOLEDB" bit.

Do I need any ODBC settings? In which case how do I set these up and how do I use them in Delphi? No, you can use the ADO connect string I see in ADOConnection there is a ConnectionString. Do I simply point this at the database on the server? If not then what? Yes, Ado Connect string should look something like this "Provider=SQLOLEDB;Integrated Security=SSPI;Initial catalog=master. I see that ADOQuery has a Connection (OK) but then it also has a ConnectionString. What would this be used for? If you want to open the Query on it's own connection. Where does ADODataSet fit in? Is it the equivelent of a ClientDataSet? shoudl it be used? is it to be avoided? The ADODataSet is the prefered componnet to replace TTable (it work better then TAdoTable in many cases while provideing most of the fanctions) I assume ADOTable is the equivelent of a Table and should be avoided at all cost!

Quote: Delphi 5 Do I need any ODBC settings? In which case how do I set these up and how do I use them in Delphi? Forget about ODBC. The preferred access method for MSSQL is ADO Quote: I see in ADOConnection there is a ConnectionString. Do I simply point this at the database on the server? If not then what? Barak did show you some examples. Generally, the connection string is semicolon separated list of pairs NAME=VALUE. For all possible NAME/VALUE pairs, you can consult Microsoft documentation. There is also a "connection string builder" available in Delphi: you can use this builder at design time for creating the ConnectionString property in tADOConnection. You can also launch the builder from code as uses AdoConEd With TConnEditForm.Create(nil) do Try SomeNewConnectionString := Edit(SomeCurrentConnectionString); finally Free; End; Quote: I see that ADOQuery has a Connection (OK) but then it also has a ConnectionString. What would this be used for? Forget about tADOQuery or tADOTable components. These are meant only for facilitating the BDE to ADO refactoring. Stick to 1) tADODataset component where you need cursors 2) tADOCommand for issuing action SQL commands 3) tADOStoredProc for invoking stored procedures As to the ConnectionString property of tADOQuery, this is an alternative way of specifying database connection instead of providing value for Connection: tADOConnection property. Personally, I prefer using Connection property. Quote: Where does ADODataSet fit in? Is it the equivelent of a ClientDataSet? shoudl it be used? is it to be avoided? See above. Quite on the contrary - you should avoid the simplified tADOQuery and tADOTable components. And no - tADODataSet is not equivelent of a tClientDataSet. Quote: I assume ADOTable is the equivelent of a Table and should be avoided at all cost! Same as tADOQuery is equivalent of tQuery - both should be avoided:-) Regards -- Roman mail: [email]info (AT) rksolution (DOT) cz[/email] URL: www.rksolution.cz Back to top Joe Griffin Guest Posted: Tue Apr 19, 2005 8:16 pm    Post subject: Re: Newby to MSSQL Geoff Marshall wrote: Quote: My client wants me to interact with his MSSQL database, and I don't have one here to play with.
