PL/SQL :: Two Consecutive Numbers Are Transposed Function Returns True
Jul 6, 2012
oracle version 11gr2.In the below sample data column a,b if there is Two (2) consecutive numbers are transposed in column B from A it should return string 'true'.
with t as
(
select '123456789' a ,'123476581' b from dual
union all
select '123456789' ,'123465789' from dual
union all
select '332211' ,'332121' from dual
union all

I am creating a function to sum five numbers (less 1). Is it possible to have an array of numbers in an SQL function, and how would this be implemented?
Here is the screenshot of my output (I cannot embed links until 5 posts!): flic.kr/p/eaSHBP
CREATE OR REPLACE FUNCTION sumfivenumbers ( n1 NUMBER, n2 NUMBER, n3 NUMBER, n4 NUMBER, n5 NUMBER) RETURN NUMBER IS Sumnums NUMBER; BEGIN SELECT SUM(n1+n2+n3+n4+n5-1) INTO Sumnums FROM DUAL; DBMS_OUTPUT.PUT_LINE(Sumnums); RETURN 1; END sumfivenumbers; / SELECT sumfivenumbers(5,5,5,5,5) AS "Five Numbers less 1" FROM DUAL;
I have an existing database with several hundred tables and triggers on the tables in the schema S1. Most of the triggers are for storing audit information USER and SYSDATE in the respective columns.
We have built procedures what will accept incoming XML parameters from a BPMS application on the intranet which will have information about which table to update, which columns to update, what values to update and what the O/S user id is. The O/S user ids are mapped to oracle user ids in a specific table. Therefore when we receive the request we can easily figure out the oracle user id. The application always connects to the database using a specified user id S2.
The trouble is, the existing tables have triggers which read :NEW.userid := USER;and whenever a DML is fired from the procedure, the function USER always returns S2, since that is the user id the BPMS application connects to and therefore the audit columns do not capture the correct information as required.
The impact of changing all the existing triggers/procedures will be a mammoth task including regression testing and will certainly not be approved by the project sponsor.
override the value that USER returns? Using session contexts, etc? If so, we can possibly set it at the point of connect and have to do nothing else.
I am interested if there maybe exists any function that would return all source tables that are present in the given sql. For example function('select 'abc' from table_1, table2') would return a list containing 'table_1' and 'table_2'.
I have an requirement to create an function which takes table or hierarchy of tables as input and returns xml output in hierarchy. Below given is the Tables hierarchy.
Requirement: Initially input was table name and using table as the root node output should generate xml of all the records of child tables.But now requirement is to give the flexibility to user to select what hierarchy he needs i.e he may select AAAA, CCC and in the nodes C1,C2,C3 and C4 if he doesn't want C3 then that node should not be shown in output.
I have created Hierarchy table having 3 columns SI.No, ParentNode and ChildNode and entered the above hierarchy relation.
1. What is the best to way (design)to pass input parameter for the function.
2. How to generate hierarchy in xml using DBMS_XMLGEN
The SAMPLE clause in the select statement works well in most cases, but we found in some instances the result is way off - between 200% to 700% discrepancy has been observed.
For example, we have thee tables with the following results:
Table1: 495,365,317 rows (20 cols, unique primary key present), SAMPLE ( 0.002018712182064212 ) returns 41,499 (about four times off - we expected about 10,000) Table2: 3,350,864,539 rows ( 5 cols, unique primary key present), SAMPLE ( 0.00029843044634040336 ) returns 9,835 (this is good as it is close to 10,000) Table3: 6,974,724,543 rows ( 5 cols, no unique primary key present), SAMPLE ( 0.00014337483779250091 ) returns 58,789 (about six times off - we expected about 10,000)
The tables got billions of rows, and that is why we want to do sampling. The sample percentage rate is computed to return about 10,000 rows in all three tables.On Table3, we ran the sampling three times in one occasion, and we got "58,570", "24,575" and "24,561"
I expected +/- 20% of variance, but 200% to 700% seems to be way too much.Once again, I stress that it does work well in most cases (another 3.4 billion table and numerous smaller tables we tested were well within +/- 5 percent of the target).I noted the presence of a primary key above because I read an article saying that the SAMPLE function relies on the existence of a primary key (which does not quite explain the examples above).Is this kind of spread something we should expect or is it a bug? Is the sampling rate too small for such large tables?
On a Oracle 11g R2 I've a table function ( PIPELINED ) returning rows selected from a table.The first time the function is selected, in a session ( I've tried to disconnect and log in again ), it returns no rows.I've tried to log the call using DBMS_OUTPUT and from what I see the select on the table function returns no rows and no output is printed. So I presume Oracle is not calling the function.
The same function on a similar environment ( same db versions, patches and database structure ) works fine. The second environment is a production environment so it has more memory and some other settings enabled.
CREATE OR REPLACE TYPE TEST_OBJ_TYPE IS OBJECT ( TEST_ID NUMBER(9), TEST_DESC VARCHAR(30) ) / CREATE OR REPLACE TYPE TEST_TABTYPE AS TABLE OF TEST_OBJ_TYPE / [code]....
I need to include the above function in a plsql package. How I can declare a object type and table type in a pks file? the syntax to include the above code in a .pks and .pkb file?
I got this code snippet online when I was looking for function that returns a table type. what exactly that Exception block does? delete the table when there is an exception, otherwise return the table type?
I have a table test with column containing dates, characters and numbers. I have to extract the number part and the three characters before the number . My data looks like :
TEST ID DATA 1 3/12/2007 2 0 3 3/8/2010 ABC 217 4 NONE 5 COLM XYZ 469 6/8/2011 6 LMN 209
For Just learning purpose This is an example found in text book but while i try to execute it fails..I am trying to set Boolean flag to true if the hire_date is greater than 5 years otherwise boolean flag to false
DELARE v_Hire_date date :='12-Dec-2005'; v_five_years BOOLEAN; BEGIN IF [code].....
For one of my OLTP table, we have skewed distribution on STATUS column and hence we created frequency histograms. NDV=7 for this column.
My question is : Do we need to have "_optim_peek_user_binds" set to TRUE in order to utilize Adaptive Cursor Sharing ?I have gone through different OTN forum and blogs and it appears that in order to generate different plans, Oracle has to Peek the value of bind variables each time. Without Peeking, how would CBO knows whether to generate new plans or not ?
For xyz reasons, optimpeek_user_binds is set to FALSE in my database and i could not find any sql_id having V$SQL.IS_BIND_AWARE='Y'.
im working with apex 4.2.1 and when i try to define a Dynamic action on any item, if the action type is "Set Value" or execute SQL/Javascript code it should appear a text field that let me define the action taking place. However this wont do..
this is what happens:
And this is what should happen:
I know that patch 4.2.2 solves some issues regarding dynamic actions but in the bug report there's no reference to such a problem.
I have the following set of numbers that i am passing in as one input into a stored procedure.
234,456,234,456,567
Now i want to take this list of numbers and use it in an IN statement:
select * from table where column_a in (P_INPUT);
however, when i try this, it give me an invalid error. I have tried inserting single quote around each value and get the same invalid error. I tried a To_char around my column, which solved the error, but it never finds a match!
I want to get 10 random numbers from existing 100 numbers. How can we get/generate random numbers ?
for example I have a table with customer ID, customer Name, having 100 record. We want 10 customers ID randomly from that 100 record not repeated any number. Have any command or procedure for that ?
I have a requirement to display numbers as equivalent alphabets , like if the stored value is 1 then it should display as 'A' ,2 means 'B' ,is there a way to find out.
CREATE TABLE APS ( ITEM_NO NUMBER, ITEM_NAME VARCHAR2(12)) INSERT INTO APS (ITEM_NO,ITEM_NAME) VALUES (1,'TEST1'); INSERT INTO APS (ITEM_NO,ITEM_NAME) VALUES (2,'TEST2'); INSERT INTO APS (ITEM_NO,ITEM_NAME) VALUES (3,'TEST3'); INSERT INTO APS (ITEM_NO,ITEM_NAME) VALUES (4,'TEST4');
-- The output to be is.
item_no , item_name A TEST1 B TEST2 C TEST3 D TEST4
I tried to convert numbers to words, it shows the below error.

Here i face probelm that he numbers must be follw by DOT "." , this is not correct if the statment only conatines numbers without DOT that not extract. As the
SELECT REGEXP_SUBSTR ( 'hello to 8898989898989 jkjk nnnm mnj' , '([0-9]+.[0-9]*)' || -- Starts with digit(s) (may or may not have digits after .) '|' || -- or '(.[0-9]+)' -- starts with decimal point ) AS result FROM dual ;
but mean i have to add . after numbers . as follow
SELECT REGEXP_SUBSTR ( 'hello to 8898989898989 jkjk nnnm mnj' , '([0-9]+.[0-9]*)' || -- Starts with digit(s) (may or may not have digits after .) '|' || -- or '(.[0-9]+)' -- starts with decimal point ) AS result FROM dual ;
