What is difference between mapping Parameter, SESSION Parameter, Database connection session parameters? It’s possible to create 3parameters at a time? If Possible which one will fire FIRST?



                                                                                                                                                                      
Scenario:

What is difference between mapping Parameter, SESSION Parameter, Database connection session parameters? It’s possible to create 3parameters at a time? If Possible which one will fire FIRST?

Solution:

We can pass all these three types of parameters by using Perameterfile.we can declare all in one parameter file.

A mapping parameter is set at the mapping level for values that do not change from session to session for example tax rates.

Session parameter is set at the session level for values that can change from sesion to session, such as database connections for DEV, QA and PRD environments.

The database connection session parameters can be created for all input fields to connection objects. For example, username, password, etc.
It is possible to have multiple parameters at a time?
The order of execution is wf/s/m.

CMN_1650 A duplicate row was attempted to be inserted into a dynamic lookup cache Dynamic lookup error.

Scenario: I have 2 ports going through a dynamic lookup, and then to a router. In the router it is a simple case of inserting new target rows (NewRowLookup=1) or rejecting existing rows (NewRowLookup=0). However, when I run the session I'm getting the error: "CMN_1650 A duplicate row was attempted to be inserted into a dynamic lookup cache Dynamic lookup error. The dynamic lookup cache only supports unique condition keys." I thought that I was bringing through duplicate values so I put a distinct on the SQ. There is also a not null filter on both ports. However, whilst investigating the initial error that is logged for a specific pair of values from the source, there is only 1 set of them (no duplicates). The pair exists on the target so surely should just return from the dynamic lookup newrowlookup=0. Is this some kind of persistent data in the cache that is causing this to think that it is duplicate data? I haven't got the persistent cache or...

SQL Transformation with examples

============================================================================================= SQL Transformation with examples   Use : SQL Transformation is a connected transformation used to process SQL queries in the midstream of a pipeline . We can insert, update, delete and retrieve rows from the database at run time using the SQL transformation. Use SQL transformation in script mode to run DDL (data definition language) statements like creating or dropping the tables. The following SQL statements can be used in the SQL transformation. Data Definition Statements (CREATE, ALTER, DROP, TRUNCATE, RENAME) DATA MANIPULATION statements (INSERT, UPDATE, DELETE, MERGE) DATA Retrieval Statement (SELECT) DATA Control Language Statements (GRANT, REVOKE) Transaction Control Statements (COMMIT, ROLLBACK) Scenario: Let’s say we want to create a temporary table in mapping while workflow is running for some intermediate calculation. We can use SQL transformat...
