Letting SQL Server generate Identity values might make your job harder if you don't know how to retrieve the new Identity values.
This statement provides a list of orders and the customers that placed those orders.
The BDE considers any SQL join to be read-only because inserting, updating, and deleting rows in a join is ambiguous.
So can we conclude that all applications that deal with data are the same and can be built using a common pattern? Other aspects, including scalability and performance, affect and influence the design.
All distributed applications must be scalable to some extent.
I have to update a column 'PPMOProject ID' in the table, but in such way that if it is empty and tricky part is I have a scope of only parent child relation ship in the table like if MP- master parent, P- parent, Child - C: ID Parent ID PPMOProject ID MP1 NULL NULL //updating here by 889 P1 MP1 898 //It should not update, because it contains already value P2 MP1 NULL//it should update by 889 if it is empty else skip it C1 P1 NULL//Here it should update by 898 C2 P1 NULL//Here it should update by 898 C3 P2 NULL//Here it should update by 889 As per above logic : When I updating PPMOProject ID in parent record, I have to check all children's and master children's , if the record is empty I have to update by Immediate record parent, it that parent is empty and need to update by master column ID, if parent record has column ID , should update by Parent ID itself.
This should be done in C# and LINQ , I have tried by below logic : var child Projects = db. Where(m = As per above logic : When I updating PPMOProject ID in parent record, I have to check all children's and master children's , if the record is empty I have to update by Immediate record parent, it that parent is empty and need to update by master column ID, if parent record has column ID , should update by Parent ID itself.
For example, the Join Data example is built around an ADODataset component that uses the previous SQL join.
If you run it, you can edit one of the fields and save the changes (by moving off the record).
CAUTION: Do not use Siebel CRM system fields, such as Id, as output properties.
The ADO Recordset object is used to hold a set of records from a database table.
The following is an example of Siebel e Script implementation of a business service for a VBC.
