JDBC Scenario: Delete all the existing records and Insert

Question

Dear All,
Scenario: IDoc to JDBC
PI need to delete all the existing records in the SQL table then need to insert the records.I have created a two statements in the target structure.
Statement1
   -> TableName
       -> action : DELETE
       -> Table : TableName
Statement2
   -> TableName
       -> action : INSERT
       -> Table : TableName
       ->Access
           -> Elements
I am getting below error while try to delete the records in the table.
JDBC message processing failed; reason Error processing request in sax parser: Error when executing statement for  table/stored proc. 'Tablename' (structure 'Statement1'): java.sql.SQLException: FATAL ERROR document format: structure 'Statement1', no key element found
Note: we use above structure in the another interface without specifying any Key for Delete operation(Server is same but different database for this two interface) and it works fine. Although the Primary keys has been set in the SQL table i am getting the above error.
let me know what are the setting need to make in PI and SQL DB to achieve this.

Answer 1

The straucture what you have deined for Delete is not correct, you should have key field in statement structure then only you can perform Delete operation.
