Updating nested table
MD_DT IS NOT NULLAND t1.unqid=t2.unqid AND t1.lt='hl') TEMPWHERE TEMP.ROW_ID=1 ; This query returns uniqueid, md_Dt for every valid uniqueid. We tried using update with select but got the error 'cannot modify a column which maps to a non key-preserved table'.Can you please suggest easy method of updating temp.md_dt into t1.md_dt. MD_DT AS MD_DT, ROW_NUMBER() OVER (PARTITION BY t2.unqid ORDER BY t2.
The optional plus ( ) is relevant if you are joining the TABLE collection expression with the parent table. How I could see my table-rows from the main-table always or how should I change the outer-join query?

With former you can't insert directly into nested table without updating nested column in main table first. I have two options as I know to do this: SELECT * FROM BDA_TAB TAB CROSS JOIN TABLE(TAB.nt_test) NET; No rows selected.
You need to decide you assign NULL to nested table column or empty table. If I have a view where I want to see all rows from the table BDA_TAB completed with the info from the nested table. Oracle Virtual Networking Google Adwords Landing...
merge into emp using dept 2 on (emp.deptno = dept.deptno) 3 when matched then 4 update set ename = dname; merge into emp using dept * ERROR at line 1: ORA-30926: unable to get a stable set of rows in the source tables [email protected] only difference here is UPDATE does this check before execution, while MERGE does this as part of statement execution. MD_DT AS MD_DT, ROW_NUMBER() OVER (PARTITION BY t2.unqid ORDER BY t2.
The right way to avoid this error is define either a primary key or a unique index/constraint on dept(deptno). MD_DT DESC) AS ROW_ID FROM t2, t1 WHERE t2.x = 'x' AND t2.y = 'y' AND t2.
