SQL & PL/SQL :: Display In List Non-Existent Value In Output
Mar 6, 2012
I am not sure if this is even possible however I will give it a try here. is there a way to take a value from an In List that doesn't exist in the table and get SQL PLus to output that value with an assigned decode construct. example.
1 select decode(count(object_name),1,'EXIST',null,'NOT EXIST',0,'NOT EXIST'),
2 object_name, object_type
3 from dba_objects where object_name in (
4 'GV_$METRICNAME',
5 'GV$METRICNAME',
6 'GV_$METRICGROUP',
7 'GV$METRICGROUP',
8 'ABC'
9 )
10* group by object_name, object_type
SQL> /
having trouble displaying stuff on screen. It compiles the program successfully but just doesnt show any output Try using this (SET SERVEROUTPUT ON SIZE 4000) does nothing though. here my code
DECLARE /*This program coverts a date from one fomat eg 1/31/10 into another format eg January 31,2010 */ /*declaring variables assign a date that is in one format*/ EXAMPLE_DATE DATE := TO_DATE(' 1/31/06',' MM/DD/YY' ); /*finding the position of where the forward slash are*/ position_finder NUMBER := INSTR(EXAMPLE_DATE,'/');
I am in a state of confusion and requires a solution for this urgently:I used to use 'Execute Immediate' statement or 'Sys_RefCursor' for forming parts of query dynamically based on user inputs and then finally execute them at runtime for updating database / saving results into a variable etc.
But as per the latest requirement, I wanted to have the resultset of such a query displayed in the grid area / results area of a database tool; say, SQL Navigator, Toad or PL/SQL developer.; just like you see the results of a normal 'SELECT * FROM TABLE1'; Is this really possible ??
see the below examples:
Eg: for Execute Immediate:
declare vtest VARCHAR2 := NULL; vdisplay VARCHAR2; begin vtest := 'SELECT FIELD_1 INTO vdisplay FROM TABLE_A'; vtest := trim(vtest) || 'WHERE FIELD_2 = ''XYZ'''; execute immediate TRIM(vtest); dbms_output.put_line(vdisplay); end;
---> This would display output into the 'Output' tab of the database tool / editor;
Eg: for SysRefCursor:
declare vCur SYS_REFCURSOR; vdisplay VARCHAR2; begin OPEN vCur for 'SELECT NULL' || var1 || 'WHERE FIELD_1 = ' || Value1; FETCH vCur INTO vdisplay; dbms_output.put_line(vdisplay); end;
---> Even this would display output only into the 'Output' tab of the database tool / editor;
===> But my requirement is: Different from these, is there any way to get this output displayed into the normal output grid / result area of a database tool ? just like you see the results of a normal 'SELECT * FROM TABLE1' query ?
order = the sequence in which they are to be displayed a sub-heading's heading_id refers to the parent heading, likewise an item's sub-heading_id refers to the parent sub-heading.
I assumed there was no need to track child content.
Now, the output format should be something like this, where the sub-headings are not repeated, nor are the items. Sort of like chapters in a book, things in a catalogue, or even topics in a forum.
Where I'm getting hung up is how to query the data so it's quick, efficient, clean and easy to read and maintain. I've only gotten to listing the sub-headings and already the query looks convoluted. So, how should I approach this? Should it be done all in one query, and always checking against the results to know when to print a new heading or sub heading. Or should I run multiple queries and save the results to a variable, and then run sub-queries off that? Is there a better way to do this, am I going about it the hard way or am I in the right direction and just haven't gone far enough with it yet?

I've gotten it to display the percentage of markup correctly(as in, multiplied by 100 with no decimal places), but I cannot for the life of me get the percentage sign to display on the right of the values(i.e. 40, but not 40%).
Here's my code so far:
SELECT title, to_char(round((retail-cost)/retail*100), '99') AS "MARKUP %" FROM BOOKS;
I've tried concatenating with both the + sign and the ampersand (&) sign, to no avail.

I just want to list and group all my tables that are linked together by constraints. I just want my tables to be able to be listed together as one particular database. my tables are , CUSTOMER, ORDER_INFO, ORDER_LINE, PRODUCT.

DECLARE v_num NUMBER; v_days NUMBER; BEGIN SELECT to_date(sysdate)-to_date(dob) INTO v_num FROM customer_details WHERE application_id=:block3.day; v_days :=floor(v_num/366); MESSAGE(v_days); MESSAGE(v_days); END;
It is giving me a result of -73...i cleared my problem. but i cound not understand the internal work happening inside the forms and pl sql machine.
