Collection of the dynamic query
Hi All-
I'm trying to get the value of the collection through the dynamic query but I am facing some problem please let me know that I hurt.
Created a function like below to run the dynamic query to select statement
create or replace FUNCTION rfunGetColumnValue ( ColumnName VARCHAR2, TableName VARCHAR2, DefaultValue OUT VARCHAR2, Criteria VARCHAR2) RETURN VARCHAR2 IS ReturnValue VARCHAR2 (32767 byte) ; Stmt VARCHAR2 (32767 byte) ; BEGIN stmt := 'begin select '|| ColumnName || ' into :1 from table(:2) ' ||NVL ( Criteria, ' ') || ' Fetch First Row only ; EXCEPTION WHEN OTHERS THEN :2 := SQLERRM; end;' ; dbms_output.put_line (stmt) ; EXECUTE IMMEDIATE stmt USING OUT ReturnValue, OUT DefaultValue; --select Valueinto into Returnvalue from dual; RETURN ReturnValue; END;
Now, I created a folder in the Package
create or replace PACKAGE Collection_PKG is type Bank_rec is RECORD ( SNO NUMBER(10), BANKID NUMBER(5), BANKNAME VARCHAR2(50), BANKSC VARCHAR2(50), ADDEDIT varchar2(1), COMPID number(5), ISBULK number(1), ROWNO number(10), ERROR VARCHAR2(500) ); TYPE Bank_tbl IS TABLE OF Bank_rec; --type Bank_cur is ref cursor return Bank_rec; end Collection_PKG; end Collection_PKG; end Collec tion_PKG;
Now, when I'm Trying the code below
DECLARE
V_EXECQUERYPARAM XMLTYPE:= XMLTYPE('<QueryParam>
<BankXML>
<Bank>
<BankID>0</BankID>
<BankSC><![CDATA[RCB]]></BankSC>
<BankName><![CDATA[Royal challenger Bank]]></BankName>
<IsBulk>0</IsBulk>
<AddEdit>A</AddEdit>
</Bank>
</BankXML>
</QueryParam>');
BEGIN
Rspbanksave(
v_SPParamList => V_EXECQUERYPARAM );
END;
create or replace PROCEDURE rspBankSave (
v_SPParamList XMLTYPE DEFAULT NULL)
IS
V_Addedit VARCHAR2 (1 CHAR) ;
Bank_tbl Collection_PKG.BANK_TBL := Collection_PKG.BANK_TBL () ;
BEGIN
SELECT Row_number () OVER (ORDER BY 1),
XT.BankID,
XT.BankName,
XT.BankSC,
XT.AddEdit,
v_CompID,
XT.IsBulk,
CAST (0 AS NUMBER (5)),
CASE
WHEN MBank.BankID IS NOT NULL
THEN
CASE
WHEN XT.BankSC = MBank.BankSC
AND XT.BankName = MBank.BankName
THEN 'R104|Entry Already Exist,R114|Short Code Already Exist'
WHEN XT.BankSC = MBank.BankSC
THEN 'R114|Short Code Already Exist'
WHEN XT.BankName = MBank.BankName
THEN 'R104|Entry Already Exist'
END
ELSE NULL
END Bulk collect
INTO Bank_tbl
FROM XMLTABLE ('//QueryParam/BankXML/Bank' PASSING v_SPParamList COLUMNS BankID NUMBER (5)
PATH 'BankID', BankName VARCHAR2 (
50) PATH 'BankName', BankSC VARCHAR2 (
50) PATH 'BankSC', AddEdit VARCHAR2 (
1) PATH 'AddEdit', IsBulk NUMBER (1)
PATH 'IsBulk') XT
LEFT JOIN MBank
ON XT.BankID != MBank.BankID
AND v_CompID = MBank.CompID
AND (XT.BankSC = MBank.BankSC
OR XT.BankName = MBank.BankName) ;
v_TotalRowCount := SQL%ROWCOUNT;
IF (v_TotalRowCount > 0) THEN
BEGIN
V_Addedit:=rfunGetColumnValue (ColumnName=> 'Upper(AddEdit)',TableName=>'table(Bank_tbl)',DefaultValue=>'',Criteria =>'');
END;
--SQL Code here
END IF;
END rspBankSave;
As I've suggested before:
To get the name of the table the column
and as others have:
Type global temporary Tables vs. table
If you give more context, more information about the bigger picture, more information about what you're trying to do and why you're going down the road you go down, you can return more useful information. But you seem reluctant to do.
For the moment, your recent posts seem to just raise the same type of question - why are you doing this?
The normal way to return data to a client is a refcursor.
It is the most effective way.
Not through collections that you seem to be put on the must-do approach.

Unit test: is there a way to make the dynamic query of the value of running after the boot process?
I wonder why the dynamic value query is executed before the boot process? Logically, it makes sense to run after them.
For example, I test a stored procedure that is supposed to delete a record, and I'd like to create this test report should be deleted as part of the startup process before execution of the stored procedure call to delete this test record. Apparently the dynamic query of value not returns not the test report in as long as the query parameter to call the stored procedure under test, which makes me think that is executed before the startup process of design...
Please advise...
Thank you

Get the dynamic query alias name
Hi all
I have a plsql function using a dynamic query.
And the function takes an entire sql query as a parameter.
The main problem is that the function must get what aliases or columns were interviewed.
For example,.
FUNCTION_GET_QUERY_ALIAS ('SELECT 1 AS col1, col2 FROM DUAL 2 AS')
Inside the function, he must find the alias name COL1 and COL2.
I would be grateful for any help.I modified print_table as fact and function to meet your needs.

You are way more complicate things here. First of all, there is no need at all for dynamic sql because the wy you are querying is incorect.
Even if you do not have an error, which you query will do is run the query on t_sce_msr_output_data once for each row returned by the cursor. Each iteration of the query will return all matching rows (i.e. lines for all the participantid in the t_sce_msr_output_data table), then the external decoding will be will force all other NULL columns for all the participantid that do not correspond to the "current" participantid
The query can be simplified to:
Select p.participantid,
Decode (p.Measureid, 10331, p.Current_Data, NULL) "10331_CURRENT."
Decode (p.Measureid, 10331, p.Goal_Data, NULL) "10331_Goal."
Decode (p.Measureid, 9640, p.Current_Data, NULL) "9640_CURRENT."
Decode (p.Measureid, 9640, p.Goal_Data, NULL) "9640_Goal."
Decode (p.Measureid, 9643, p.Current_Data, NULL) "9643_CURRENT."
Decode (p.Measureid, 9643, p.Goal_Data, NULL) "9643_Goal."

Decode (p.Measureid, 10332, p.Goal_Data, NULL) "10332_Goal."

You probably want to pivot these results by participant, if so look in the note from the FAQ for the columns of the rows.

Hey everyone, have a quick question. I just started using ColdFusion week last to my current job and I do a database work. One of the scripts I'm working on that is dynamically allow a user to enter information for a source of data, their username, password, database, then an operation of query-by-example-esc on this database. However a question that I am currently running shows these data. So say I got into a simple HTML form and it is passed in as the name "Colonne_1". So when I go to access my SQL statement, I'd be using:
#Form.Column_1 #.
My problem comes when I am printing these data. Normally I use the following code:
< cfoutput query = "GetResults" >
#username #.
< / cfoutput >Where # is the column #username I was looking for. How would I be able to have dynamically it out everything that needs to be entered as column name in colonne_1? So, something like:
< cfoutput query = "GetResults" >
# #Form.Column_1 # #.
< / cfoutput >Thank you!
table notation is your friend.
QueryName ["columname'] [line number]
or, in your case,
QueryName [' #variable for columname # "] [row number]

Access the results of the dynamic query database...
CF colleagues:
I need to execute a loop of 4 times, to access the four distinct values a data offline in a test results table (tbl_results), where all four are in line with the student (WHERE studentid = etc.).
It looks like this...
< cfset variables. TimeTotals = 0 >
< cfloop from '1' to step "4" = = = '1' index = "timrec" >
< cfquery datasource = "MyDSN" name = "rs_time" >
SELECT Btime #timrec #.
OF tbl_results
WHERE studentid = 'jack '.
< / cfquery >
< cfset variables. TimeTotals = variable. TimeTotals + (? rs_time.) BTime #timrec # value?) >
< / cfloop >
QUESTION: How should I address this #timrec # value Btime? Not that way, I know, but how?
Looking forward to your wisdom, with gratitude,
Hans
There are two ways to attack this, but you're close enough. One way is to simply include a column alias in the query, and then use it to make reference to results:
SELECT Btime #timrec # LIKE feeling
OF tbl_results
WHERE studentid = 'jack '.

How to create the table dynamically in the procedure, I tried below to how his error getting.

30EA2 - UNIT TESTING - value dynamic query truncating dates time.
So I use the installation of SQL Developer Unit Testing (very nice by the by) for a bit now and just recently upgraded to the latest beta version (3.0.02.83). Looks like a bug has been introduced by which the dynamic query of value are truncate all time of all DATE data type information.
This causes sadness serious for my current test cases and for me since I have to go back to the previous beta version :)I noticed that, in the new 30EA2 parameter:
AddVMOption - Doracle.jdbc.mapDateToTimestamp = false
has been introduced by default in
[SQLDEveloper_install_dir]/sqldeveloper/bin/sqldeveloper.conf
Perhaps it has something to do with the behavior of incorrect date, try to remove the parameter and check again.

Hello
I have a table1 as below
ID (NUMBER), keyword (VARCHAR2)
----------------------------------------------------
1, HAS
2, B
3, C
Another table2
Name (VARCHAR2)
--------------------------
Alice
Bob
Jack
I need to write a stored procedure to check if the 2 mactched of the char keyword table1 table name. How to write the dynamic query in my PL/SQL in a stored procedure so that I can generate query similar to
SELECT * from table2 where name like '%x %' where I need to replace X by the tank in table1
Help, please.
Thanks in advance,
MarryI need to write a stored procedure to check if the 2 mactched of the char keyword table1 table name
You could simply join the tables:
SQL> with table1 as ( select 1 id, 'A' keyword from dual union all select 2 id, 'B' keyword from dual union all select 3 id, 'C' keyword from dual ), table2 as ( select 'Alice' name from dual union all select 'Bob' name from dual union all select 'Jack' name from dual ) -- -- select * from table1, table2 where name like '%' || keyword || '%' ID KEYWORD NAME ---------- ------- ----- 1 A Alice 2 B Bob 2 rows selected. -

It's the game ('25', ' 04 "). the number of list might be n.

Dynamic display of columns in the pivot query
I have a table called STUDENT_SCORE. I need to display the avarage score/month for 2 years and the monthly score until today "month.
Then assume that it is April 2009. The report will look like
Roll_id 2007avg 2008avg Jan09-Mar09 Feb 09
101 80.9 70.9 89.7 90.9 56.8
102 70.9 23.9 87.2 90.0 76.8

The script below produces what you want (as far as I can tell, without your desired results).
Student_score_smry subquery Gets the year and monthly averages of student_score.
It is completely static: it always produces 11 monthly columns (from January to November) and the names of columns hardcoded (m01 through m11).
For dynamic column names you need, I used SQL * COLUMN more orders.
To get the variable number of monthly columns you need, SELECT from the main query clause uses a script under (dynamic_month.sql) to only show the correct number (which can be 0).The student_score_wk_smry of subquery retrieves the weekly averages of the student_score_wk.
He, too, is completely static: it always produces 6 weekly columns with names hardcoded (w1 through w6).There are four preliminary motions, that write two scripts under:

How to dynamically change the generated query through the "query by example".
Hi all. I'm relatively new to the ADF, so I've been beating my head against a wall trying to figure out how to do this... Any help would be greatly appreciated!
What I try to do is to make a custom search (query) against a set of tables in the database. Normally, I would use just the ability to "filter" the af: table to do this (query by example). However, the query I need to run has three specific requirements:
1. I need to change the 'WHERE' clause differently according to the field in which the user enters criteria in. For example:
-If the user enters something in the field 'name' of filter, the default ADF BC will do is add '%' to the value entered, turning it into a query "begins by". I also want to prepend a '%' to the input value, (for example "doe %'), it becomes a query 'contains '. I don't want the user to see the '%', I put at the beginning of the field in the UI, however.
-If the user enters a value of 9 digits in the field 'SSN', do a query of "accurate". If they penetrate only 4 digits, do a query "ends by". (I could always just a query "ends by" - for example "% of values" - even if they have put in 9 digits, and that would work.) However, an exact match will run faster because of the index on the field, so I want to use that if we put 9-digit.)
2. I also need to change the SELECT part of the query based on which fields are used in the filter.
3. If the user enters the filter values in several fields, I need 'OR' them together. The default functionality, it's that they are 'linked' together.
Can someone point me in the right direction? My thought was somehow replace the manner in which the query is generated when the user presses ENTER to run the filter. But, I can't seem to understand where and how to connect it to this process to customize the SELECTION and WHERE the parts of the generated query. I'm sure that there is a way, and I hope more experienced ADF'ers can direct me to the solution.
Thank you!

Sort on dynamic query problem!
Hello
I have a dynamic query written in pl/sql, when I check "Sort" for each field in the report attribute, error message resurrected as "ORA-01785: ORDER BY item must include the number of an expression in the SELECT list.
If I do not check sort, it works very well. In my applications, I need all the fields sorted by user, how do I solve this problem?
My query as below:
declare
Ask varchar2 (2000): = "select";
s_class varchar2 (1000);
cursor c1 is select * from demo_preference;
Start
for c1_val looping c1
If c1_val.login is not null then
query: query = | » ' || 'login ' | ',';
end if;
If c1_val.id is not null then
query: query = | » ' || 'id ' | ',';
end if;
.......
end loop;
query: = SUBSTR (query, 1, length (query)-1);
s_class: = ' (NVL (: P2_class, "%" |)) ''null%'') = ''%'' || "zero percent" OR
EXISTS (SELECT 1 FROM apex_collections WHERE collection_name = "P2CLASSCOL" AND class = c001))';
query: query = | » ' || ' from ming.reg_report_view1 where '.
|| ' ' || s_class;
Return (Query);
end;Maybe the internal column used when you clicked the sort is not indicated in the report. Try to use aliases when you build the query string, it might help apex internally to identify a column even if its order is changed to another user. After all, the order of the columns in the code is dynamic and I assume that even the number of displayed columns can vary that could sort on a column that is identified by a number not valid.
How about somewhere, displaying the report query so that you know what is the exact query processing, it could give you the best information on the problem.
If the problem persists, use a collection that is extracted these record using the same query string, then replace the report to view the collection and then set the sort column on. This way Summit could get confused about which columns are being sorted and it would just sort on a c001... C050 column as if it were a string (Yes problems with the number of sort columns when you do this).

Estimation of lines wrong with the size of the dynamic partition
Hi all
Version 11.1. RAC 4 knots. I met a sql that runs slowly because the bad LINES estimate. Here's the exectuion its plan.
Please note that the plan is just a part of the plan real exectuion. And I have collected statistics for all the tables involved, so I think that statistics should be updated.
Please see below. CBO estimated that only 640 lines for step 5 and 115 for this SQL totall. But the real result was almost 14K lines.
I don't know if the CBO made this mistake because of the size of the dynamic partition?
But I made another simple test, in which I just used a predict as partition_key =: b. the exectuion plan resemblesPLAN_TABLE_OUTPUT Plan hash value: 2984909170 -------------------------------------------------------------------------------------------------------------------- | Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Pstart| Pstop | -------------------------------------------------------------------------------------------------------------------- | 0 | SELECT STATEMENT | | 115 | 33005 | 2801 (8)| 00:00:09 | | | | 1 | NESTED LOOPS | | 115 | 33005 | 2801 (8)| 00:00:09 | | | | 2 | PARTITION LIST ALL | | 1 | 201 | 1482 (5)| 00:00:05 | 1 | 30 | |* 3 | TABLE ACCESS FULL | OPT_ACCT_ASDN_TYPE2_DIM | 1 | 201 | 1482 (5)| 00:00:05 | 1 | 30 | | 4 | PARTITION LIST ITERATOR| | 640 | 55040 | 1319 (12)| 00:00:05 | KEY | KEY | |* 5 | TABLE ACCESS FULL | OPT_FUND_GEN_SPNDG_FCT | 640 | 55040 | 1319 (12)| 00:00:05 | KEY | KEY | --------------------------------------------------------------------------------------------------------------------
The estimate is more reasonable this time. Can someone show me why CBO made this mistake or why think CBO, there are only 600 lines while in reality there are more than 20 k lines.PLAN_TABLE_OUTPUT Plan hash value: 1115434777 ---------------------------------------------------------------------------------------------------------------- | Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Pstart| Pstop | ---------------------------------------------------------------------------------------------------------------- | 0 | SELECT STATEMENT | | 980K| 80M| 1390 (17)| 00:00:05 | | | | 1 | PARTITION LIST SINGLE| | 980K| 80M| 1390 (17)| 00:00:05 | KEY | KEY | |* 2 | TABLE ACCESS FULL | OPT_FUND_GEN_SPNDG_FCT | 980K| 80M| 1390 (17)| 00:00:05 | KEY | KEY | ----------------------------------------------------------------------------------------------------------------

Published by: user12064076 on March 2, 2011 01:11The 'A-Time' is known to be wrong sometimes. However, the "buffers" are correct.
So the reading of the partition of the fact Table was 14Mo scan (1804 puts buffer @8 KB each). Which is really not much.
Yes, the cardinality estimate is off, but for a scan of 14Mo Oracle effort is not very high.Cardinality for the recovery of the fact table is based on the statistics of column for the BUS_UNIIT_SKID and the ACCT_SKID. Because Oracle does not know what BUS_UNIT_SKID and ACCT_SKID values will be extracted from the Dimension table that results in the query, it can't really come up with an accurate estimate - even more if the data are biased.
From the column of table-level statistics, the optimizer knows how many distinct values of BUS_UNIT_SKID exist in the table.
From the column of table-level statistics, the optimizer knows how many distinct values of ACCT_SKID exist in the table.But for a lost combination (BUS_UNIT_SKID, ACCT_SKID) in any unknown partition (the ' unknown' because it does not know the values or the partition during the query optimization) you can calculate an estimate only - the combined cardinality estimate is generally
(somewhat simplified)
Estimated_Number_of_Rows_of_Unknown_Partition X (1/Distinct_BUS_UNIT_SKIDs X 1/Distinct_ACCT_SKIDs) OR Estimated_Number_of_Rows_of_Unknown_Partition X (5% estimate X 5% estimate)that will be very low.
You can run a plan to explain the "simplified" with the 10053 EVENT query
alter session set events '10053 trace name context forever, level 1'; explain plan for SELECT ...... exitand display the trace file generated for more information on how Oracle considers the cardinality.
Your problem with the complex query is not likely here. You have to restyle the entire query instead of focusing on the estimation of cardinality for this fact table.
The query can be modified to help identify the Partition - Partition pruning - advance statistics?
The query can be modified in order to carry out the operations in a different sequence - get first performance and the effort of each step of the query Plan.(BTW: the Dimension table reading was the most expensive part of this performance)
