SQL & PL/SQL :: Passing Hierarchy As Input To Function That Returns XML?
Aug 3, 2012
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

I have a requirement where in I have to store large data in one of the database columns using stored procedure.
I have declared the column as CLOB as it can store upto 4GB and also the input parameter for the procedure as CLOB. But when I am trying to pass large data it is not allowing to store as it is throwing literal string too large error.
Is there any restriction in the data size to be passed to the stored procedure?
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'.
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?
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'.

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.

How do I put condition for Null value in this procedure And set dateTo = sysdate if v_day,v_month,v_year are null.
I have a function that returns the total sum of an account. From reports I call the function passing the account code. The function sums the values for that specific account code and returns the value. In my function I have the following code :
where account_code = P_CODE.
Eg. The value of :P_CODE is 'CS'.
I now want to pass multiple account codes ('CS','TV',LJ') to the function. How do I change the IN clause in the function to accommodate multiple values.
I have tried using the instr function, but it does not work. eg. AND instr(o.ACCOUNT_CODES,','||P_CODE||',') > 0

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?
Is it possible to sort records based on hierarchy in such a way that records sorts in sequence and records of same level comes in the last (in sorting order)
Example: I expect the rows with H8889,H9955 & P6666 & P5555 to be sub-category values value for product hierarchy H555888.
If there are rows with H8888987 as Product_hierarchy, we will pull up those rows too for product hierarchy H555888. The extra condition is we drill down only on 7 character mod_prod_number not on 5 character mod_prod_number. We pull out all sub category mod_prod_number for all distinct Product hierarchy.
In the above resultset PART='SUBPART1' does'nt have any child as evident from the connect_by_isleaf (LEAF=1) .Is there any way to create a pseudo record if such values are returned by the query, i.e., if a part has no tree under it a dummy record should be created i.e. in this case an additional record should be returned by this query. i.e., as below. the LEVEL=3 record should be created.
Is it possible to find the locked objects in hierarchical order. Consider the below example
--Connect to scott schema create table block_session(a NUMBER, b VARCHAR2(100)) / insert into block_session select rownum,rownum*10 from dual connect by level<=10 / COMMIT / GRANT ALL ON block_session to HR / update scott.block_session SET a=10 where b=10 [code]......
Is it possible to get all locked table details in hierarchical order?
INSERT INTO NODE_LVL VALUES('TBL_APL','TBL_AFL'); INSERT INTO NODE_LVL VALUES('TBL_APP','TBL_ACS'); INSERT INTO NODE_LVL VALUES('TBL_ADD','TBL_ADW'); INSERT INTO NODE_LVL VALUES('TBL_ADP','TBL_ADV'); INSERT INTO NODE_LVL VALUES('TBL_AOP','TBL_AOV'); [code]......
Table 'TBL_APP' is having 2 parent nodes i.e 'TBL_AOV' and 'TBL_ADV' SELECT * FROM node_lvl WHERE child_node = 'TBL_APP';
At level 5 there is duplicate nodes i.e 'TBL_APP' and 'TBL_ACS' as parent_node and child_node respectively.
SELECT PARENT_NODE, CHILD_NODE, LEVEL FROM NODE_LVL START WITH PARENT_NODE = 'TBL_ACF' CONNECT BY PRIOR CHILD_NODE = PARENT_NODE;
I want to suppress such duplicates. So I added DISTINCT
SELECT DISTINCT PARENT_NODE, CHILD_NODE, LEVEL FROM NODE_LVL START WITH PARENT_NODE = 'TBL_ACF' CONNECT BY PRIOR CHILD_NODE = PARENT_NODE;
BUT requirement is to maintain the same order (of hierarchy) as it was before adding DISTINCT.
