Have a table which has 3 columns id,name,time where time is of datatype timestamp and it stores the time when the row was inserted. Need an query which accepts 2 parameters as input Ex: Start_Time,End_Time and all the rows in between the above mentioned timestamps must be deleted.

based on the above result set , for a particular group ,only that op will be retained which comes out in the query . say for example , we have got 1,2,3,'D' for group 1,2,3
now since we have got the D Operation from the above query , i don't need the other two rows .i.e.
(1,2,3,'I');
(1,2,3,'U');
what is the best way to delete the data we don't want retaining the rows we want ,using a single sql statement . Also , for the result set row 7,7,7,T I first need to delete the group containing T operation, and insert two new rows .i.e. 7,7,7,D and 7,7,7,I .

How to select the transactions out of the database that occurred within 70 seconds of each other. The toll_date field is a TIMESTAMP field.
Problem is, I seem to only get transactions that occurred within 70 minutes of each other. On the timestamp field I break the math down into the seconds in a day and I add 70. I then subtract that value and add that value to the timestamp and I should get anything between those values right?

I have to create the following table. The fields Trend_Date, Price and Trend are already given. I have to calculate the field permanently and to insert the value in this permanent table.
Fields:
The field price belong to the value of a product during the trade.
The field trade_date belongs to the moment of the trade.
The field trend belongs to the future behavior of the the price. Here, the price of the present moment is compared to the following price (possible characteristics: 'UP', 'DOWN', 'STABLE').
The field permanently belongs to the time (in seconds) how long the value of the field Trend_Date (depending on the price) is still true.
For example:
Row 1: The trend in row 1 is 'UP' and it has a price of '11'. Until row 3 this remains true (the price is greater or equal to 11). In this case, the difference between row 1 and row 3 are 9801 (rounded) seconds.
Row 2: The trend in row 2 is 'DOWN' and it has a price of '12'. This remains true till to the end (the price is never greater than 12) In this case, the difference between row 2 and row 11 are 97346 (rounded) seconds. To calculate the 97346 seconds the field has to consider that between row 2 and row 11 are two days. There will be no trade between 18:00 and 07:00 o'clock. This belongs to 7 hours for each days, in seconds (2*46800) 93600.
-> 190945-93600 = 97346s
Row 6: The trend in row 6 is 'UP' and it has a price of '5'. This remains true till to the end (the price is never smaller than 5) In this case, the difference between row 6 and row 11 are 65729 (rounded) seconds. To calculate the 65729 seconds the field has to consider that between row 65729 and row 11 are one days. There will be no trade between 18:00 and 07:00 o'clock. This belongs to 7 hours for each days, in seconds (1*46800) 46800.
-> 112528-46800 = 65729s
Row 9: The trend in row 9 is 'STABLE' and it has a price of '8'. Until row 10 this remains true (the price is equal to 8 ). In this case, the difference between row 9 and row 10 is 14418 (rounded) seconds.
Row 11: Is empty because there are no values to compare.
Example Table
TRADE_DATE --PRICE --TREND --permanently
02.01.13 11:21:42,720000000--11--UP--9801
02.01.13 12:44:03,236000000--12--DOWN--97346

(both these fields a_std and a_time are coming as varchar from the parent table in a cursor.(basically they are time period and actual arrival time respectively)
i was juggling with the attempt to make varchar to timestamp or date..but caught with Round up /Round down)
Formula ->
A = Round down [A_TIME - A_STD]
B = Round up [A_TIME) - 10 minute + A_STD]
where
A_TIME VARCHAR2(8) N Time (Format" HH:MM AM/PM") eg "3:50 PM"

Allowed values for A & B after round up/down = multiple of 10 ( 11:00,11:10,11:20 etc.)
