COMP_BLOOMBERG_CODE = xls01.col1), COMP_AMS_P_BV_RATIO=( SELECT col15 FROM xls01 WHERE INVST_COMPANY. student_arrear regno papercode name m1 m2 m3 total result i need to update student_master from student_arrear those who have passed i have to match the regno and send sql query for this May 29, 2013 - pm UTC no create no inserts no look even more, no explanation of what "who have passed" - what defines "who have passed". The challenge is that when doing the update portion of merge, as in update table1_new set row = orig_row, orig_row needs to be defined as %rowtype of the table in the loop for 200 tables. COMP_BLOOMBERG_CODE = xls01.col1), COMP_AMS_LTM_P_E_RATIO=( SELECT col14 FROM xls01 WHERE INVST_COMPANY. ) merge into emp using (select emp.rowid rid, NVL2(test1.desc1,test1.desc1, SUBSTR(ENAME,1,5)) d1, NVL2(test1.desc1,test1.desc1, SUBSTR(job,1,5)) d2 from test1 ,emp where emp.deptno=test1.deptno( )) YOUR_QUERY on (emp.rowid = your_query.rid) when matched then update set dept_desc = d1, desc1 = d2; i am having 2 tables 1.student_master regno papercode name m1 m2 m3 total result 2. So table1 will be merged into table1_new, but would like to write generic procedure/package for all 200 at once and not 200 procedures. COMP_BLOOMBERG_CODE = xls01.col1) WHERE EXISTS ( SELECT xls01. COMP_BLOOMBERG_CODE= xls01.col1); June 22, 2010 - am UTC not sure what your point is, but you have demonstrated perhaps the slowest way to achieve this update of a join. ref cursors have to be known at COMPILE time, you'd need the structure to be known when you COMPILE. loop over them in the dictionary, generate code for them. :) Hi Tom, There are 2 tables Table1 type cpty amt1 amt2 c a 10 0 c a 20 0 nc a 30 0 nc a 40 0 c b 50 0 c b 60 0 nc b 70 0 nc b 80 0 Table2 amt A cpty 100 a 115 a 120 a 125 b 130 b 140 b Trying to write an single update statement that will do the following 1.



with dbms_sql, you'll have one procedure that can process all 200 tables, it can describe what the cursor returns, it can bind to what the cursor returns and it can fetch an arbitrary row with an unknown (at compile time) set of columns. then run said code Tony Fernandez, if you are merging data into another table, don't use a cursor at all - If at all possible, query user_tab_columns to build a native dynamic MERGE statement to do the data move. Only nc type amt2 column in table1 should be updated 2.

select col2 col3 as result from table1 inner join (select distinct col_x2 from table2 where col_y2 = 'super OK') temp on temp.col_x2 = col_x1 where col4 = 'OK' How can I use join in my update statement? you update a join when you want the data from T1 to overwrite what is in T2 and you join T2 to T1 by T1's primary key. MAX_RANGE_CNTRL where jobs.rate_type = 'A' and jobs. nc2 nc3 nc4 nc5 nc6 nc1 matches c1, nc2 matches c2, nc3 matches c3 What I need to do is update particular records from one of the tables, but only the common columns The conceptual SQL should be some in the likes of (this is not a query don't hit me ;) it's what is intended to be done): Update table_extended set table_extended.nc2 = table.c2, table_extended.nc3 = table.c3 where table_extended.nc1 = table.c1 = @parameter Is there a simple way of doing this update? Many thanks, May 29, 2008 - pm UTC and if the other bottlenecks exist for merge, they shall exist for create table as select - plus reindex - plus grant - plus constrain what are your waits for, got a tkprof with waits? Is there any other way i can use to speed up the update by any efficient means! And why do i get an 'invalid column name' error when i run this?
