Unique Constraint Violated

Scenario:

Database errors occurred:
ORA-00001: unique constraint (INF_PRACTICE1.SYS_C00163872) violated

Database driver error.
Function Name : Execute
SQL Stmt : INSERT INTO D_CLAIM_INJURY_SAMPLEE(CK_SUM,DM_ROW_PRCS_DT,DM_RO W_PRCS_UPDT_DT,CLAIM_INJRY_SID,DM_CRRNT_ROW_IND,INCDT_ID,ENAME,J OB,FIRSTNAME,LASTNAME) VALUES ( ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
Database driver error...
Function Name : Execute Multiple
SQL Stmt : INSERT INTO D_CLAIM_INJURY_SAMPLEE(CK_SUM,DM_ROW_PRCS_DT,DM_RO W_PRCS_UPDT_DT,CLAIM_INJRY_SID,DM_CRRNT_ROW_IND,INCDT_ID,ENAME,J OB,FIRSTNAME,LASTNAME) VALUES ( ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

Solution:

check the definition of unique index columns and then below query on source to fine out thd duplicate rows.

if index def like
create index on targettable(col1,col2,col3);

select col1,col2,col3,count(1)
from sourcetable
group by  col1,col2,col3
having count(1)>1

either u have to delete those records from source or use agg in informatica mapping

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...

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...
