I have a stat table that got info like login_date,user_id etc.For a specific user, i have a requirement based on the no of days difference between the current login date and last login date.
For example, Tom logged in on June 4th 2013. His previous login was May 31. So no_of_days_difference is 5 days.How to programmatically get this for each user inside a pl-sql sub block.
I take a select into a cursor and process it record by record.I have to do sum based on a column and display row by row by using dbms_output.put_line .... So the sum has to happen based on a column. Based on the column value i need to display the cumulative sum as well.
Example:-
col1 col2 amount DL AADD 25 DL BBCC 10 DL BBRR 15
Sum value for DL ----- 50
TX ADED 20 TX EDWW 60
Sum value for TX ----- 80
All the above data should be displayed using DBMS_OUTPUT.PUT_LINE in a pl/sql code. I use cursor to take the values from the table but the problem i face is .... I am not able to display the sum based in the col1 values.
Since i use the cursor .. i took the col1 values in to a variable and checked every time old_variable = new_variable if yes then continue the sum else display the sum value.
once i get the above check satisfied i am loosing a new col1 row in the check. The next loop only run for the new col1 values -1( which is used in the check loop).So is there any better way to get the solution or is there a facility to store the previous loop values in a cursor ? so that i dont have to loose that one row of data.
I am not able to come up with proper loop so which can identify that the col1 has changed and you have to display the sum value.
Practicing in VM. My question is, I deleted the physical files of the database on Sunday but I'm having physical files backup on Friday. firstly i done restore, Performing incomplete recovery , I'm getting error like "Cannot open Archive log"
On Saturday, I changed path of archive log but I'm not aware of archive previous path location. How can we find previous path location of archive log?
We want to find out difference of data for some tables between current day & previous day. We can use query with minus operation but it will take lot of time since table size is in range from 200 to 500 GB. We have to do this exercise every day.
insert into a values(1,3,'Y',5); insert into a values(2,2,'Y',4); insert into a values(3,3,'N',3); insert into a values(4,4,'Y',3); insert into a values(5,1,'N',6); insert into a values(6,2,'N',5); insert into a values(7,2,'Y',4); insert into a values(8,3,'N',2); insert into a values(9,4,'Y',2); insert into a values(10,1,'Y',3); . SQL>select * from v$version; Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
My logic should have the output as follows without 5th column: sourcerowleveldpnqtyremark13Y522Y4This row in main table shouldn't be displayed in the query result as it has
dpn='N'44Y3*3=9In this row qty=9 will bedisplayed.
It will compare the value of level column with its previous row level col,if it is the parent of the current(ex.current is 4 and previous is 3 parent of 4),then it will check the dpn of previous row ,if dpn='N' then qty of parent will be multiplied with qty of current row and displayed under qty column.this row will not be displayed as dpn='N'this row will not be displayed as dpn='N'72Y4*6=24in its previous row level value is same so it will check the previous to previous row where level is 1(parent of current row) and dpn='N' ,then it will multiply the qty of that row with current row and display the value in qty column.this row will not be displayed as dpn='N'94Y2*2=4In this row qty=4 will be displayed.It will compare the value of level column with its previous row level col,if it is the parent of the current(ex.current is 4 and previous is 3 parent of 4),then it will check the dpn of previous row ,if dpn='N' then qty of parent will be multiplied with qty of current row and displayed under qty column.101Y3It will not check for the previous rows as level 1 doesn't have any parent.
I am trying to import the schema into 11g database, which i took on Oracle 9i database. While import is running, data file is full as auto extension was not enabled.
I got the following error:
. . importing table "WO_GL_ACCOUNT_SUMMARY" IMP-00058: ORACLE error 1653 encountered ORA-01653: unable to extend table PWRPLANT.WO_GL_ACCOUNT_SUMMARY by 1024 in tabl espace PWRPLANT IMP-00018: partial import of previous table completed: 7055845 rows imported.
Then I increased the datafile size and finally Import terminated successfully with warnings. At this point, I want to know whether WO_GL_ACCOUNT_SUMMARY Table was imported with out missing any rows .
when i press when button pressed trigger, i want first the form will delete all the previous data and then populate the data from the table, that's why i used clear_block first, but this clear_code is not working here. my coding is given below
go_block('show'); clear_block(NO_VALIDATE); declare cursor c1 is select * from qtr_demand order by 1; begin [code]..........

I want to know the DDL statements executed on a table. Example:
i have a table test1 with structure as below: test1 (aa number, bb varchar2(10))
After some period of time, one DDL statement to alter the column is issued.
alter table test1 modify (bb varchar2(30));
so new table structure is: test1(aa number, bb varchar2(30))
Basically i would like to find these 2 DDL statements executed on this table - test1, so that i compare which column get modified and what modification done.
Is this information stored in any data dictionary table?

1) how to find a primary key of a table in oracle, for example if I want to drop a index in table , how do I find what is the primary key in a table so that I can issue that command.
P/s: I don't have OEM installed so I must use SQL command
Example of dropping the index ALTER TABLE table_name drop CONSTRAINT constraint_name;
I need the column name and table name which is having the particular value in the whole database.
E.g. :We have 'Scott' value in emp table emp_name column. and we have lot of tables. here we need emp_name and emp as emp table is having scott value in emP_name column.
