SQL & PL/SQL :: Get First Week Starting With First SUNDAY Of Year
Nov 9, 2012
I want to get the week of the year.
Conditions are:
1. Year's first week starts with first Sunday of the year. (6th Jan 2013 will be the starting week (week 1) in Year 2013)
2. 2nd Jan 2013 will be the last week of the previous year i.e. 2012 (either 52th or 53rd week)
At many place I found the below solution:
select to_char(to_date('01-JAN-2008','DD-MON-YYYY')+1,'IW') week_number from dual;
But its not working for the given dates (2nd Jan 2013, which should fall in the last week of 2012, and 6th Jan 2013, which should be the starting week of 2013).

I had to get a query to give me all the Mondays of a IW week in a year. I think as per the IW weeks there are around 52.1 weeks in a year. So basically, I want the starting Monday of every week. I would then store those values in a variable and use them in APEX as column headers. Online I saw some samples not related with this, but where looping was done using the all_objects. Not sure if that is the right approach.
The problem is since this is not stored in any table, how can I loop like 52/53 times such that the output shows all the Mondays (date format) for a given year. Basically, the output would be 52/53 rows with a date(Monday of the week).

I have a table of records with a date_modified column. I would like to simply report the count of updates made each week. For example, given:

148315761/29/2013
154364281/31/2013
148066382/1/2013
[Code]...
I would like to return:
Week Updates
43
57
69
77
84
Although in place of the week number, providing either the value for the last day of the week or the first day of the week would be just as good.
how to go about this task.

I am running 10g on Linux, and last week someone messed up a database and it needs to be restored to 27 December. I am not a DBA, out regular DBA is on vacation till mid January,
I know we have archivelog on (I can see .arc files for the database), and I also have a backup of the actual data files and control files from when the database was first created. So in other words, I have all archive files and the initial data files. What i do not know is how to set the restore till December 27.

I have a table with a count of customers for about a year, but I only want to select Wednesday and Thursday of each week, starting at the beginning of dates. Table is simple and has two columns. Each row is Distinct to a Date, there are no Date duplicates, it's counted for each day of the year.
column 1: count of customers, count(customer_id)
column 2: Date
Not even sure if this is possible to select a date using the day name ?
Basically I want to select each Wednesday and Thursday from each week and compare the counts week over week, over week for all week to see if the counts are going up or down, to get trends .

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 am getting problem while starting the CRS. Below is the necessary details:
1) I am using oracle 11g R2 RAC, with 2 node named RAC1 and RAC2
2) I have 3 diskgroup named DATA, DATA1, DATA2
3) OCR and voting disks are stored on ASM diskgroup
On node RAC1, CRS is started and /etc/oracle/ocr.loc is having the below entry:
ocrconfig_loc=+DATA
ocrmirrorconfig_loc=+DATA1
On node RAC2, CRS is stopped and /etc/oracle/ocr.loc is having the below entry:
ocrconfig_loc=+DATA
ocrmirrorconfig_loc=+DATA2
note the difference in "ocrmirrorconfig_loc". The difference was occured because I updated the OCR location on RAC1 when RAC2 was down.
Now I am trying to repair the RAC2 using below command. This command must be run as root user when HA service is started but CRS must be stopped.
ocrconfig -repair -replace +DAT2 -replacement +DATA1
but this showing error "PROT-21: Invalid parameter", because to run this command diskgroup must be mounted. But diskgroup cannot be mounted until the CRS start. SO this is a conflicting situation.
