Receiver JDBC

Question

Hi
the receiver JDBC structure
                                                                   occurence
<statement1>   ----------------------------->                   1..unbound    or    1..1                               (1)
<Table>            ----------------------------->                1..1 per statement always                             (2)
<access>         ----------------------------->                  1..1 per statement always                             (3)
   <fld1></fld1>                                         
   <fld2></fld2>
</access>
<key> --------------------------------------->                   1..unbound    or  1..1                                       (4)                          
  <val1>
</key>
</statement1>
<statement_response>  --------------->                        should be 1..unbound <b>if</b> statement request is 1..unbound (here statement1)
                                                                                should be 1..1 <b>if</b> statement request is 1..1 (here statement1)                        (5)
<row>                                       
<row>
</statement_response>
-&gt; In which case we go for occurrence of statement (here statement1) = 1..unbound ??
-&gt; if i need to select from one table do i need to use this as 1..unbound ?? Yes/No
--&gt;each statement response (means all rows of that query) will come under row node with multiple occurrence Yes/No??
--&gt;if i want to delete the rows from table where col= (value array) in this case i have to give key occurence as 1..unbound??Yes/NO
--&gt;if i want to select all the data from one table..i no need any key..but as per sap help doc..if we dont specify the key the adapter will not accept and shows some error message...so i should some dummy key value..and need to compare with NEQ to NULL or space???
--> If i want to select the data from JDBC using the receiver structure...can i declare all the field types as string in request and response structure..or it should match the data types of fields in data base..?? if so how it should be in select request and response structure??
(1) (2) (3) (4) (5) are right or wrong..if wrong correct me..
Thanks

Answer 1

Krish,
Please see the below response
Answer-1
If you are selecting data from Different tables then you need to define Statement as 1.. Unbounded
Answer- 2
No. Since you are selecting data from one table - you can define it as 1..1
Answer -3
There will be only one Statement_Response per Statement. In other words if you have Multiple Statement in the Request , then you will have Multiple Statement(x)_Response
So Under Statement_Response you will have Multiple Rows(for each record in the database) . YES - Row has to be 0.. Unbounded
Answer- 4
YES - You are correct
Answer-5
YES - you can define them all as a STRING. It shouldn't be a problem
Hope it helps!
Thanks!
