try to write a query to find out the basic data lineage against the snp_map... tables. Need some help. What I need is:
mapping name, source schema, source table, source column, target schema, target table name, target column and mapping, such as:
load emp info HR EMP EMP_ID STG STG_EMP EMP_ID AS IS (or HR.EMP_ID)
load emp info HR EMP EMP_SAL STG STG_EMP EMP_SAL HR.EMP_SAL* (1+ 10%)
load tmp info STG STG_EMP UPD_DT sysdate
Thanks
