Scenario:

What is the difference between joiner and lookup?

Solution:

Joiner
Lookup
In joiner on multiple matches it will return all matching records.
In lookup it will return either first record or last record or any value or error value.
In joiner we cannot configure to use persistence cache, shared cache, uncached and dynamic cache
Where as in lookup we can configure to use persistence cache, shared cache, uncached and dynamic cache.
We cannot override the query in joiner
We can override the query in lookup to fetch the data from multiple tables.
We can perform outer join in joiner transformation.
We cannot perform outer join in lookup transformation.
We cannot use relational operators in joiner transformation.(i.e. <,>,<= and so on)
Where as in lookup we can use the relation operators. (i.e. <,>,<= and so on)

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...
