There are four columns as follows, but I need to delete those rows from the third column only where the second letter of the word appears as vowel. For example, I want to delete the rows having the words, 'Ramu' and 'Ravi' only.

I want my query to return the rows of the table where a column contains a specific values first in a certain order, and then return the rest of the rows alphabetized.
For Example:
Country
ALBANIA
ARGENTINA
AUSTRALIA
....
CANADA
....
USA
....
Now i want USA and CANADA on top in that order and then other in alphabetized order.
I'd like to know if it is possible to track DML actions issued on a specific table by a specific user, for example , i tried :
AUDIT SELECT on SCOTT.DEPT by HR by ACCESS;
I get an error, where is my syntax error ?
i want to know if it's possible to do it without trigger ?
I need to get the number of rows based on one condition for certain time period. For example, writing a query for 3(any) hrs , i need to get the output as count of rows as hourly basis. Like these:
Date Time Count
12/08/2010 16:00 234
12/08/2010 17:00 345
12/08/2010 18:00 645
This is what I've been trying to do.
I have the following table:
FOOTBALL PLAYERS < ID, NAME, ATTRIBUTE>
100-JIM-TALL
101-BOB-STRONG
102-MARK-SMART
...etc
I want to form a query that regardless of the total returned records, I will be able to specify how many of each "kind" of players I want returned. There are several good reasons that it has to be one query and not many.
If i have a CSV file that is in the following format
"fd!","sdf","dsfds","dsfd",
"fd!","asdf","dsfds","dsfd",
"fd","sdf","rdsfds","dsfd",
"fdd!","sdf","dsfds","fdsfd",
"fd!","sdf","dsfds","dsfd",
"fd","sdf","tdsfds","dsfd",
"fd!","sdf","dsfds","dsfd",
Is it possible to exclude any row where the first column has an exclamation mark at the end of the string.
i.e. it should only load the following rows
"fd","sdf","rdsfds","dsfd",
"fd","sdf","tdsfds","dsfd",

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 .

View 4 Replies View RelatedI know how to select the last N sets of rows, using DENSE_RANK - where multiple rows have the same timestamp but I want to only select those rows which do NOT have the top 2 unique timestamps.
i.e.:

WHERE DENSE_RANK > 2 order by myTimestamp DESC, HISTORYID, USER_ID;

and to_char(Createddatetime,'dd/mm/yyyy HH24:mi:ss') between 'sysdate-1 06:00:00' and 'sysdate 05:59:59'
But nothing comes up
where as definitely there are records between times because when i do and Createddatetime between sysdate-1 and sysdate I see valid records coming up.
