SQL & PL/SQL :: Query On Single Column To Display As Rows
Aug 5, 2010
I has a table of structure of varchar2 datatype.
NO
----------
1-2
3-4
5-6
desired output is:
SQL>1
2
3
4
5
6
The table has single column & the values may differ,that is, they may have 1-2-3-...-n in a single row, but the desired output is to be in the rows as shown above.
I tried concepts of SQL up to my knowledge, but I failed. The query to be done only in SQL.complete this query.
I have 3 tables, Emp(Emp_id,emp_name),dept(dept_no,dept_name),emp_dept(emp_id,dept_no). Emp tabl ehas some 20 employes id who belongs to different departments.There are few employee who belongs to multiple departments as well. I want to fetch records of emp_id, emp_name, dept_no in the following format.
TABLE_A ------------------------------ ID DEPT CRS ------------------------------ 1 CS CS_100 2 SCIENCE SCI_150 3 MATH MATH_400 4 HISTORY HIS_110
[Code]...
To display CRS from TABLE_A where DEPT = 'MATH' but in the following format.,
-------------------------------------------- NO DEPT CRS -------------------------------------------- 1 MATH MATH_400, MATH_550, MATH_230 --------------------------------------------
instead of., -------------------------- NO DEPT CRS --------------------------- 1 MATH MATH_400 2 MATH MATH_550 3 MATH MATH_230 ---------------------------
I am trying to write a script where a particular post code from a table is having more than 3 telephone numbers.Both the columns are in the same table. How to fetch.
Table is P_Order Columns are DELIVERY_POSTCODE and TEL_NO... Condition DELIVERY_POSTCODE has more than 3 TEL_NO
I have a query which returns nearly 20k rows, as per the requiremnet we need to append all these rows in specific format and insert into single clob column.in the below procedure test_clob.textt is clob field.
CREATE OR REPLACE PROCEDURE pro_test v_mas_seq NUMBER (9); v_gov_total NUMBER (20, 2); v_emp_total NUMBER (20, 2); v_text_exp CLOB; v_pageaccess VARCHAR2 (15); v_dto NUMBER (7) := 4011486; v_batchno NUMBER (20) := [code]....
create table T (student_id number, class_id number, quiz_id number, marks number)
some sample rows like
INSERT INTO T VALUES (1,1, 1, 50); INSERT INTO T VALUES (2,2, 2, 40); INSERT INTO T VALUES (3,1, 3, 34); INSERT INTO T VALUES (1,1, 4, 10); INSERT INTO T VALUES (1,1, 5, 30); INSERT INTO T VALUES (1,1, 6, 29); INSERT INTO T VALUES (3,2, 7, 34); INSERT INTO T VALUES (3,2, 8, 33); INSERT INTO T VALUES (3,2, 9, 56); INSERT INTO T VALUES (1,1, 7, 90); INSERT INTO T VALUES (2,2, 8, 0,); INSERT INTO T VALUES (1,1, 8, 80); INSERT INTO T VALUES (2,2, 8, 65); INSERT INTO T VALUES (1,1, 9, 34); INSERT INTO T VALUES (2,2, 9, 11);
each student belongs to one class_id. each student participates in many quizes. each quiz has its unique id. each student can appear once in a quiz_id
I am doing the below analysis and query:
1. with below query I am finding which student_id had most marks in any 3 successive quizes (see the 3-1 part below) in the query..
With above query, I can play around and find for any 'n' number of consecutive quizes, like marks in 2 consecutives quizes, 3, 4 and so on but for each 'n' value I've to run a seperate query mentioning (2-1) or (3-1) or (4-1) and so on..
since my table is big and there are about 400 quizes so what I want to find out is for each 'n' consecutive quiz (from 1 to 400) which student had most marks for each consecutie 'n' quiz. Like in 1 (consecutive) quiz which student had the highest marks and then 2 conseuctive quiz who had most marks and then in 3 consecutive quiz who had most marks and so on till 400 consecutive quiz who had most marks... rather than running query for each 'n' value seperately i want a single query that can give me a summary of most marks in each n consecutive quizes...
Is this possible to get the above output from one single query? If there are two or more students with equal most marks for any 'n' conseutive quizes then both should come in the summary.
I dont want to print the repeated value(NAME) of C1 multiple times as below.
C1C2C3C4 NAMEJOHN10ABC SMITH30DEF ROBERT60XYZ
I could do it using the below query using union with the rownum.
select * from ( select rownum rn, c1,c2,c3,c4 from table_new ) where rn =1 union select * from ( select rownum rn, decode(c1,null,null),c2,c3,c4 from table_new ) where rn between 2 and 3
Is there any other way of displaying using a single sql query.
I need a single select query which converts all the rows into a single value . Below is my requirement :
Create table email_tbl(emailid varchar2(30)); insert into email_tbl('1@y.com'); insert into email_tbl('2@y.com'); insert into email_tbl('3@y.com'); insert into email_tbl('4@y.com');
Now , I need a single select query which gives me the below results.
1@y.com,2@y.com,3@y.com,4@y.com
I have done the above by using a cursors in the pl/sql objects.But want to achieve this with a single sql/query.
I need a generic query to generate total # of records for each table in a schema, total # of records that are not null for each column in the table, and total # of records that are null for each of those columns in those tables.
ex:
the output should look like this.
owner schema table_name total# recs in the table, column_name, ------ ------ ---------- ------------------------- -----------
# of records not null # of records null ---------------------- --------------------
From my form with a single button i need to display a report with a paramter. Report is displaying fine but the parameter is not getting passed. I did the following behined my button i add this
If i remove the where condition the whole table data start appearing in the report but adding where condition is not accepting 20 as i send from the FORM Button. And the report with blank data appeared with column headings.
I have developed one report but need one formatting suggestion. There is one field called "DESCRIPTION", I want the value of this field to be displayed in a single line. Now the big values are wrapped into multiple line.
Now,
DISPLAY ---------------- This is a Oracle Report.
I want, DISPLAY ------------------------ This is a Oracle Report.

creating a single row from 2 rows based on the first column which is not unique.
CREATE TABLE RELATIONSHIP ( RelationshipID number not null, DepartmentID number not null ) INSERT INTO RELATIONSHIP VALUES (1,1) INSERT INTO RELATIONSHIP VALUES (1,2) INSERT INTO RELATIONSHIP VALUES (2,3) INSERT INTO RELATIONSHIP VALUES (2,4)
There are a few more tables that would need joining, which I can provide but at the moment I'm struggling with this part, I know there is a problem with the formatting here but not sure how to get tabs correctly
I am bit confused to display all the rows in a column using stored procedure like
In sqlserver: create procedure test as begin select * from table; end in sqlserver it is working perfectly.
In oracle: create or replace procedure test is begin select * from table; end;
But in oracle i am getting an error like select * into something like that.I understand the error. i.e. i need to move the column values into variables.if it a single row then there will be no problem.i want to display all the rows in the table at one time.i can not use cursors.
i want to display all the columns of emp table in rows.O/P should be like below:---------------------------------------------Columns------------empnoenamesaldeptnomgr
CREATE TABLE T1 ( id NUMBER, START_date DATE, end_date DATE, end_date1 DATE, end_date2 DATE, end_date3 DATE, LEVEL1 number ) /
[Code]...
I have data in the first table as mentioned above I need to insert multiple rows into the second table for the same ID depends on the level, If it is level 1 then two rows for same ID first reocrd start_date as the start_date and end_date as end_date from the table t1 for second record start_date is end_date in t1 and end_date for this record is end_date1 column in table t1.
If the level is 3 then the table t2 should have four records for one id and the phase is the value for each record for one ID for example in level 3 we have 4 records for one id and phase should be 1,2,3,4.
writing the sql, to transform a single row into multiple rows. I am trying to create multiple rows based on a value of a column in the table.In the below example, I am trying to create the rows based on the 'Col2' values. find the below example:
Original table data:
Col1 Col2 Col3 Col4
Row1 a1 a,b,c 01 ON Row2 b1 d,e,f 02 OFF Row3 c1 g,h 03 ON
I want the above table to be transformed into below:
Col1 Col2 Col3 Col4
Row1 a1 a 01 ON Row1 a1 b 01 ON Row1 a1 C 01 ON Row2 b1 d 02 OFF Row2 b1 e 02 OFF Row2 b1 f 02 OFF Row3 c1 g 03 ON Row3 c1 h 03 ON
