I put a primary key on B(id) because if there is NO SUCH constraint -- the update is totally ambigous -- if there is more then 1 value of B1 in B for a given ID -- we cannot tell what row in B should be used to update the row in A. REGISTRATION where BIN NOT IN (select BIN from VIS. Its working very nicely.i will greateful to u forever.i was suffering by this problem for a long i am using the following / insert into VISTEMP. i could envision problems with only a second of granularity on a clock -- you could miss a record or two due to that. d) I don't program forms -- you can try otn.- Thank u very much for ur nice reply.

Even the idea create a temporary table holding only primary key and Column b, and then apply cursor to it is slow. Would u please help me how can i faster my procedure.u have given information 9i it same for oracle8i & dev6i.please help me Thank u very much for ur kind update information is really nice and working very insert----same prolem. That means -- just using math here -- that we have 600 seconds, 12,000 queries to run, 12000/60 = 20, so we are doing 20 per second -- or each query is taking 0.05 cpu seconds to run. do anything 12,000 times and you might have a problem tho! this might be one of the rare times that a temp table can be useful.I am think of the way without using cursor, script as below. I don't understand what's the problem.i am going to give u full overview of my problem. The software is available in different portion of the country for data entry and report generation etc. What about: create global temporary table gtt ( id int primary key, cnt int ) on commit delete rows / you'll add that ONCE, it'll become part of your schema forever....Given that, we can: [email protected] select * from a 2 / ID A1 ---------- ------------------------- 1 Hello 2 World The following updates are equivalent as well - they do the same thing differently. REGISTRATION); RUN and Computer in BIG Busy mood(Hang).

In update portion i am facing another problem by ur recomended code. INSERT into abc values (RTRIM(col1), RTRIM(col2) .) There is another option where I can use SELECT RTRIM(col1), RTRIM(col2) from xxx where RTRIM(col1) = yyy and then directly use insert into target table without RTRIM.It is best to use the above update of a JOIN if possible (optimizer has best chance of getting a good plan). REGISTRATION where not exists (select null from VIStemp. b)in privious question i told u that i am exporting incremental and edited data by using system date. In my B(big table record-79186) and in S(small table record-12871). Can you please tell me which option performs better if the number of records are in millions. I have a table t1 which is having all orders information.But the 2nd Where clause simply return the message of `more than one row is return', since the id is unpredictable and this create a `many to many' relationship in both tables. Many Thanks, (script) REM* the where-clause of the update cannot work UPDATE table b SET column_b1 = ( SELECT MAX(column_a1) FROM table_a a, table_b b WHERE a.id=GROUP BY a.id) WHERE table_IN (SELECT MIN(id) FROM table_a GROUP BY id); Your example is somewhat confusing -- you ask "update column a1 in table a where data in column b1 in table b" but your update shows you updating column b1 in table B with some data from table a. Every month the client office is to give data(NEW & EDITED) "BY DATE RANGWISE" to the headoffice in CD. Now, you "two step" it: insert into gtt select b.id, count(*) cnt from tabb b, taba a where = and a.cycle = b.cycle and b.site_id = 44 and b.rel_cd in ( 'code1', 'code2', 'code3' ) and b.groupid = '123' and is null group by / that gets all of the id/cnts for only the rows of interest.Additionally -- given the way the where and set clauses are CODED in the above -- it would succeed. The Headoffice is merge the data into their system. For migration data first of all i create another temporary user named VISTEMP then cotinuing this kinds of code insert into VISTEMP. Now we can update the join: update ( select a.pop, from taba a, gtt b where = ) set pop = cnt / and thats it. Hi Tom, Im selecting approximately 1 million records from some tables and populating another set of tables.You can also perform more complicated updates in Oracle.You may wish to update records in one table based on values in another table.
