SQL ,Stored Procedures and DataProviders in C/AL?

gulamdastagir · 2006-12-10

hi

ADO.NET

1.You use a Connection Object to Connect to a DATA PROVIDER(ODBC/ORACLE/OLEDB/SQLSERVER) at Runtime.

2.You use a Command and DATAADAPTER /DATAREADER object to Run your SQL and Stored Procedures

3.You use the Datasets which give the disconnected functionality to ADO.NET

C/AL

eg. OnAfterGetRecord(): Item.GET("Primary key");

My question is C/AL where is the database provider,Stored Procedures and most importantly where is the SQL???

C/AL in origin has it's own Database. Now it is possible to use a SQL-DB but the code is (almost) the same for a Navision-DB and a SQL-DB.
So all the SQL statements are generated by the C/AL.
So no Database provider, no stored procedure, no SQL. Only C/AL. All the DB-calls are written in C/AL. No need to open the DB, because this is done automatically when logging into Navision.
It is possible to connect to another DB, but this is done using ADO written with C/AL statements. Search the forum for some examples.

C/AL runs inside the database, so you don't need to connect to it. It does not use SPs, although internal NAV communication does seem to use them. I would advise not to touch those SPs though, or run the risk of corrupting the database.

Assuming i have built my own stored procedures, is there a possibility to execute the stored procedures using C/AL and also pass values into them?
