Aug 26, 2013
I have a table which contains the multiple records for single ID No. Now i have to select single record which contains the latest date. here is the structure Name
Null Type ------ ---- ------------ ID_P NUMBER NAME_P VARCHAR2(12) DATE_P TIMESTAMP(6) Records---------------------1 loosi 22-AUG-13 01.27.48.000000000 PM1 nammi 26-AUG-13 01.28.10.000000000 PM2 kk 22-AUG-13 01.28.26.000000000 PM2 thej 26-AUG-13 01.28.42.000000000 PM

I have made a travel booking system which comprises of 3 forms
1)Travel Booking form 2)Reservation Form 3)Cancellation Form
Under one booking number i can add multiple users in which they can have there multiple travels.
Users can cancel there individual travels under a prescribe booking number which on doing the Cancel flag turns to 'Y'.
What i want is, If a user is cancelling his/her travel under any booking number then while retriving the records in Travel Booking form, the travels which are cancelled should not be in enable mode.
For one user there can be 4 travels out of which 2 are cancelled, how can i track only those records whoes cancel flag is set to Y. some logic to find it out. Else can i use :system.cursor_record. If yes, How to use it for this system.
Scenario 1 Query should check for priority record(25), if the start_date and end_date of that priority record is the max in that group, records will not have any split.output will be the same.
DC Store St Date End date Priority 955 3 1/1/2010 12/31/9999 25 966 3 4/5/2011 10/10/2011 50 977 3 10/12/2011 12/12/2012 100
output
DC store St Date End date Priority Rank 955 3 1/1/2010 12/31/9999 25 1 966 3 4/5/2011 10/10/2011 50 2 977 3 10/12/2011 12/12/2012 100 3
Scenario 2 If priority record is not covering the max range, then split the records as shown below,
1. during the time period 1/1/2011 & 4/30/2011 there were no other DC for that store so rank would be 1
2. the next range would be 5/1/2011 to 6/29/2011 we have 2 records in service so the record with low priortiy would be ranked 1 and second priority would be ranked 2
3. similarly, for 6/30/2011 to 10/1/2011 we have 3 records in service and it will be ranked accordingly on the priority.
DC Store St Date End date Priority 966 3 6/30/2011 10/1/2011 25 955 3 5/1/2011 11/30/2011 50 977 3 1/1/2011 12/31/2011 100
output
DC store St Date End date Priority Rank 977 3 1/1/2011 4/30/2011 100 1 955 3 5/1/2011 6/29/2011 50 1 977 3 5/1/2011 6/29/2011 100 2
[code]....
Scenario 3 This works similar to scenario 2
DC Store St Date End date Priority 966 3 2/1/2011 12/31/2011 25 955 3 1/1/2011 12/31/2012 50 977 3 5/1/2011 06/31/2011 100
output
DC store St Date End date Priority Rank 955 3 1/1/2011 1/31/2011 50 1 966 3 2/1/2011 12/31/2011 25 1 955 3 2/1/2011 12/31/2011 50 2 977 3 5/1/2011 6/30/2011 100 3 955 3 1/1/2012 12/31/2012 50 1
Note: Number of records in the input can vary and ther can be duplicates in the date interval
CREATE TABLE ID_comments ( ID CHAR(10 BYTE) NOT NULL, S_COMMENTS VARCHAR2(255 BYTE), P_COMMENTS VARCHAR2(255 BYTE), C_COMMENTS VARCHAR2(255 BYTE) );
For each Id, I can have multiple records.
Below is the insert script of one of the ID:
Insert into ID_comments values ('0813654254','','JR/0813653606 single',''); Insert into ID_comments values ('0813654254','','JR/0813653606 single',''); Insert into ID_comments values ('0813654254','','JR/0813653606 SINGLE',''); Insert into ID_comments values ('0813654254','','JR',''); [code].......
Now I want to select only one record from this table for an ID, which will have "not null" values for s_comments,p_comments,c_comments columns. If for some ID , there is no "not null" row for any column, then pick up the "null" row/value for that column.
The structure is like this may contain multiple records like Comp_id, Comp_name, ISIN will be same, but column_name will contain the column_name to which its corresponding column_value needs to be populated to.
Oracle 11gI have a large table of 125 million records - t3_universe. This table never gets updated or altered once loaded, but holds data that we receive from a lead company. I need to select records from this large table that fit certain demographic criteria and insert those into a smaller table - T3_Leads - that will be updated with regard to when the lead is mailed and for other relevant information. select records from this 125 million record table to insert into the smaller table.
I have tried a variety of things - views, materialized views, direct insert into smaller table...I think I am probably missing other approaches. My current attempt has been to create a View using the query that selects the records as shown below. Then use a second query that inserts into T3_Leads from this View V_Market. This is very slow. Can I just use an Insert Into T3_Leads with this query - it did not seem to work with the WITH clause? My Index on the large table is t3_universe_composite and includes zip_code, address_key, household_key.
CREATE VIEW V_Market asWITH got_pairs AS ( SELECT /*+ INDEX_FFS(t3_universe t3_universe_composite) */ l.zip_code, l.zip_plus_4, l.p1_givenname, l.surname, l.address, l.city, l.state, l.household_key, l.hh_type as l_hh_type, l.address_key, l.narrowband_income, l.p1_ms, l.p1_gender, l.p1_exact_age, l.p1_personkey, e.hh_type as filler_data, 1.p1_seq_no, l.p2_seq_no , ROW_NUMBER () OVER ( PARTITION BY l.address_key ORDER BY l.hh_verification_date DESC ) AS r_num FROM t3_universe e JOIN t3_universe l ON l.address_key = e.address_key AND l.zip_code = e.zip_code AND l.p1_gender != e.p1_gender
ct_id and limit_id is match column used for mapping.
now i want the total count of no of records in test_master in which test_master column value not exceed limit master column limit value if any one column exceeds its limit then the same row will be in my count criteria.
cursor_A IS select * from table_a where condition_A; cursor_B IS select * from table_a where condition_B; record_A is a recorded of cursor_A%ROWTYPE record_B is a recorded of cursor_B%ROWTYPE
I define a procedure like pro_A(record_in cursor_A%ROWTYPE) can I overload this procedure by defining pro_B(record_in cursor_B%ROWTYPE)?
If I can't, Can I call pro_A by passing record_B as the parameter to it?
I am using toad to output the details of the database. (I need these details in a format which i can then import into excel) However, When I run sporadic individual records through my query, the results come back correct and as expected. But when I run the full data set through my query a lot of the records have different values than what they do when run individually!
Ive spent all day on this script and its really a hack of various other cursors and scripts brought together. Its driving me mad as my code doesn't seem to be wrong (since the results are correct when a single record is run) yet there must be something wrong as my full data set does not return correctly!
Can I create an external table for loading this file based on selection of fields driven by the record identifier which is the first field of each record, except for the firt two?
For e.g In the above file, for records which say 'abc' in it's first field, I want to load the 2,3,6,8 fields delimited by a comma (the values may as well be null in those fields) and for records which say 'Product' in their first fields, I want to load 5,8,9 and 10 fields from the same file. Basically, I want to know if we can use instr function while choosing the fields line by line based on a search criteria in the file. There will be less columns in my table than the number of fields in the csv file, so I guess I got to mention 'MISSING FIELD VALUES ARE NULL' option. There is another challenge too - I have to skip loading the first two lines from the file to the table.
I have written a big pl/sql proc for doing the same, using utl_file.get_line option, but it is still untested and I would be extremely happy to believe that this can be achieved by creating an external table too.
My form consist two datablock cust_mstr,cust_dtls, each customer code consists two or three contact details records, when i delete the single detail record instead of deleting single record it deletes all the details records from cust_detail table.
Here by i attaching my form for your reference pls find the code in delete button
I have 2 blocks,in one i insert student_id and when i click on the button i should get all his courses in the other block...
BUT.. when the student has more than 1 course I get this:
when button pressed trigger raised unhandled exception ORA-01422
Here is the button
begin
select TEST_STUDENT_INFO.stud_name,TEST_STUD_CRSE_DETAIL.crse_no, TEST_COURSES.crse_name,TEST_STUD_CRSE_DETAIL.crse_type,TEST_STUD_CRSE_DETAIL.crse_type_desc, TEST_COURSES.crse_time INTO :stud_name,:crse_no1,:crse_name,:crse_type1,:crse_type_desc1,:crse_time from TEST_STUDENT_INFO,TEST_COURSES,TEST_STUD_CRSE_DETAIL where (TEST_STUD_CRSE_DETAIL.STUD_ID =:TEST_STUD_CRSE_REG.STUD_ID) and (TEST_STUDENT_INFO.STUD_ID =:TEST_STUD_CRSE_REG.STUD_ID) and (TEST_COURSES.CRSE_NO = TEST_STUD_CRSE_DETAIL.CRSE_NO) and (TEST_STUD_CRSE_DETAIL.CRSE_TYPE = TEST_COURSES.CRSE_TYPE);
end;
but if the student has ONLY ONE course it WORKS FINE!
Consider below is a multi record block rows, i want to hide "23". Is it possible using Set_Item_Instance_Property or any other built-in is there in oracle forms to hide a single row field in a multi record block.
Is there a way we could define a record or a nestedtable with a type based on weak refursor i.e
TYPE RC IS REF CURSOR; C2 RC; Type t is table of c2%rowtype; Following is some more explanation of what I am trying to do.
I have a table T with column A and B. Column A is a primary key with number 1,2,3,4,5,6, Column B has diffrent sql stmts stored. i.e 'Select * from emp', Select count(1) from dept' and so on. So table will look like
1 Select * from emp 2 Select count(1) from dept
Now I want to select statements stored in table T one by one and execute them by using cursor. Problem arises as i need to fetch the cursor into some variable but the outcome of each statment is diffrent and oracle does not allow to use cursorname%rowtype for a weak ref cursor.
I have used sql for my school projects and work projects. not too extensively though. I came across this issue and read a lot of blogs but still not luck.
I need to obtain all the sub_grp_nbr's that have a prodt_ctgy_cd of 05 but not 02. so according to the data above, i should only get the results of where extra_column = 3 and 6
I am loading data file using SQL Loader in TOAD 10.5.1.3 in Oracle 10g using the control file below and loading data into 2 tables post1.thead and post1.tdetl. THEAD contains item level transaction and TDETL is detail level when a transaction has a discount or promo attached to for that item. When the
LOAD DATA APPEND INTO TABLE post1.thead WHEN (1:5) = 'THEAD' TRAILING NULLCOLS (file_type POSITION(1:5)CHAR,
[code]....
A particular THEAD value may have 0, 1 or many TDETL corresponding values.below is a sample data file. When the position 21 in the TTAIL has a value of 1 or 2, then we know that there is a promo or discount applicable to the ITEM (THEAD).
What I want to acheive is to accurately reflect a TDETL to its corresponding THEAD, as both THEAD and TDETL are loaded into separate tables. How can we have the 2 records correlated?
How to achieve "Prev_Value" column as shown below without using ORACLE analytic functions
I have records stored in table for various categories and based on ID / Name / Office / Product / Category combination I want to achieve previous value column through efficient SQL query
I have a sql query where I need to select only records with an 18 month gap between max(date) and previous date( no dates between max(date)and 18 month gap date), when I run the below query it should only select supid 130, not 120 (even though 120 does contain an 18 month gap date it also has a date that is less then the 18 month gap( '25-NOV-2012','DD-MON-YYYY'). how would get the query to look back 18 months for the next date and evaluate the month_between.
. example:
create table supply(supID number(8), supply varchar2(20), supdate Date,supamount number(13,2)); insert into supply values(100,'Tapes',to_date('01-AUG-2013','DD-MON-YYYY'),50.00); insert into supply values(100,'TV',to_date('01-APR-2013','DD-MON-YYYY'),250.00); insert into supply values(100,'Discs',to_date('25-DEC-2012','DD-MON-YYYY'),25.00); insert into supply values(120,'Tablets',to_date('25-AUG-2013','DD-MON-YYYY'),15.00);
[Code]....
and p.supid in(select s.supid from supply s where months_between
I have a fairly standard Purchase Order form which contains pre-loaded data (been uploaded from an XML file).When the Purchase Order is processed, the form updates a Price History table only if the Price on the PO_Details changes.The code for updating the price history table is contained in a PRE_UPDATE trigger on the PO_Details Data Block.
No other data changes on the PO_Details table.I now want to change this so that the Price History table is updated even if the price does not change i.e I want to create a history record for each record on the PO_Details irrespective of whether it was updated or not.
Is there an alternative trigger that I can move my code to (ie move it from PRE_UPDATE) to some other trigger that is fired for each PO_Details record even if there is no change.
I need to create a query that returns record by record a field qty_progr with the cumulate qty considering previous records. The result should be the following:
