I got a two tables, table the_table_1 consist of customers and the other one the_table_2 consist of channels.
And I need to get list of channels by contract which are an assigned to customers.
The select below give me a only assigned channels but I need to get a contract_key too from the_table_1.
select o.channel_name from the_table_2 o
minus
select o.channel_name from the_table_1 a, the_table_2 o
where a.contract_key=237092201
and a.offer_channel_key=o.OFFER_CHANNEL_KEY
And the select under (after minus) gives a list of non assigned channels by contract_key:
select o.channel_name from the_table_1 a, the_table_2 o
where a.contract_key=237092201
and a.offer_channel_key=o.OFFER_CHANNEL_KEY
where difference lies between these operators or clause, & whether there is any "except" operator in oracle, i know other three are used bt dont think oracle uses "except" too..as far as i have seen "NOT IN", "MINUS" , "NOT EXISTS" are exactly similar?
i have two tables having some fields .In table table1 there is 2 lakh rows and in table table2 there is 3 lakh rows.In both table 2 lakh rows are common.I have to find those 1 lakh rows which are distinct but the condition for this i have to use only sql joins not minus or subquery or any function.
when i doing this.select t2.id,t2.name,t2.loc from table1 t1,table2 t2 where t1.id <>t2.id;
|* 2 | TABLE ACCESS FULL | b | 1 | 23 | 4 (0)| 00:00:01 |
| 3 | TABLE ACCESS FULL | a | 300 | 14700 | 4 (0)| 00:00:01 | -------------------------------------------------------------------------------- - How do i optimize it best?
I am using the below query to show the difference of data between two tables using minus operator.
teh result is correct, but is there a way can it show with a flag with new rows and updated rows something like "N" for new row and "U" for updated row.
create a procedure so that I could get minus query of 2 table as a result.
I have two table 1- src_table_list ,2- tgt_table_list both tables have 2 columns : serial_no,table_name and 100 records each. and details mentioned in column "table_name" are actually tables name which present in my testing database.
so I need one procedure which will pick one table_name from src_table_list and one table_name from tgt_table_name each time recursively and provide minus query as a result. as below.
select c1,c2,c3,c4 from table1 --(fetched from src_table_list) minus select b1,b2,b3,b4 from table2 --(fetched from tgt_table_list)
create the procedure..as I have to prepare minus query for more than 200 tables and then I need to test them for integration testing..
I am searching the simplest way for ad hoc MINUS.I do:
SELECT * FROM uam_rss_user_XXXXXXX WHERE host_name IN ('XXX0349', 'XXX0362', 'XXX0363', 'XXX0343', 'XXX0342', 'XXX0499', [code]....
and look in the table which values are missing (values that are in host_name IN but not in actual table).is there a simpler way for doing an ad hoc MINUS? I know to insert values in temp. Table. How are experienced Oracle pros doing this task?
Quote:drop table p; create table p (qty number(3), beg_no number(5)); insert into p values(5, 110); insert into p values(8, 786);
drop table s;
create table s (used_no number(5)); insert into s values(111); insert into s values(113); insert into s values(791);
Table p: it has ticket quantity and ticket begining number. Thus according to first record ticket number will begin at 110 and will end at 110+5 (Beg_no +qty). According to second record ticket number will begin at 786 and will end at 786+8 (Beg_no +qty). This table can have many records.
Table s: it has ticket numbers which are sold. The ticket will always be any number from table and will lay in any record in this format between beg_no and beg_no+qty
I want to run below query to get the result set that I am after. But It takes long time even with the indexes...Here in IM_Mapping table is having 1.7 mio records and T_Extract table about 35000 records. All the other tables having below 1000 records

Middle EastThe table contains more than a million records, pivoting using a group by clause will have performance issues. Would it be possible to do this with Xquery or any other method?
I need to return the stored result in a record by ref cursor. In the below code I am displaying the result through DBMS_OUTPUT.PUT_LINE but i need to do it through ref cursor to display the result.
declare type r_cursor is REF CURSOR; c_emp r_cursor; type rec_emp is record ( name varchar2(20), sal number(6) [code].....
I need to write a query which will get me output: 233445, i.e. all the three rows concatenated. How can it be done? I want to do it through sql only and not to use PL/SQL. Is this possible?
I have the following data (columns IDx, STARTx and DURATION) and want to create the column RESULT. Example:
create table zTEST ( IDx number, STARTx number, DURATION number, RESULT number ); insert into zTEST (IDx, STARTx, DURATION, RESULT) values ( 1 , null , null , null );
[code]...
The logic behind the table is like this: when there is a Start-ID and a Duration, the field Result shall show the Start-ID for the next records (Duration period). Even if there is a new Start-ID in row 9, it is ignored since threre is already a current signal from row 6 which is still running.
select dem.NUM_PCE, memo.comment from demand dem, dem_comment memo where CONCAT(dem.NUM_PCE,dem.NUM_DEMANDE) = memo.parentId (+) and memo.dateCreation = (select MAX(DEM_DATE_CREATION_MEMO) FROM dem_comment memo WHERE memo.parentId = CONCAT(dem.NUM_PCE,dem.NUM_DEMANDE))
I should have a result with this request but there's nothing and the problem come from the fact that when the following condition is not met, there are no resulty even if there's an outer join
and memo.dateCreation = (select MAX(DEM_DATE_CREATION_MEMO) FROM dem_comment memo WHERE memo.parentId = CONCAT(dem.NUM_PCE,dem.NUM_DEMANDE))
This condition makes Oracle ignores the outer join..I have tried to add this:
select dem.NUM_PCE, memo.comment from demand dem, dem_comment memo where CONCAT(dem.NUM_PCE,dem.NUM_DEMANDE) = memo.parentId (+) and (memo.dateCreation = (select MAX(DEM_DATE_CREATION_MEMO) FROM dem_comment memo WHERE memo.parentId = CONCAT(dem.NUM_PCE,dem.NUM_DEMANDE)) or memo.dateCreation is null)
but there are too much records and the result is not consistent
For obscure test purposes I need to modify an existing SQL query to emit the rows N times instead once. I'm aware of the possibility to "UNION ALL" the query with itself to get the all rows twice.
But as I require the resulting rows to be emitted around ten to hundred times this approach doesn't seem sensible to me. Not to speak of the missing possibility to parametrize the number of "repetitions".
I have a sql query which fetch the data from 4 different tables. I want to write the output of that query into a excel or a CSV file without using TOad and all. Let me know is it possible via creating function or procedure.
