I have a dynamic query stored in a function that returns a customized SQL statement depending on the environment it is running in. I would like to create a Materialized View that uses this dynamic query.
View 1 RepliesI'm trying to build a dynamic sql inside an Oracle procedure, and return it as a SYS_REFCURSOR to ADO.NET using ODP.NET in Oracle 11R2. Below is my table:
CREATE TABLE "TFWDB_ENTIDADE"
(
"CD_ENTIDADE" NUMBER(10,0) NOT NULL,
"DC_ENTIDADE" VARCHAR2(100 BYTE) NOT NULL,
"NM_ENTIDADE" VARCHAR2(255 BYTE) NOT NULL,
"CD_TIPO" NUMBER(5,0) NOT NULL,
"ID_STATUS" CHAR(1 BYTE) DEFAULT ('1') NOT NULL,
CONSTRAINT "PKFWDB_ENTIDADE" PRIMARY KEY ("CD_ENTIDADE"),
CONSTRAINT "CHFWDB_ENTIDADE" CHECK (ID_STATUS IN ('0', '1'))
);
Below is the procedure I build to SELECT it:
create or replace procedure spfwdb_sl_entidade_1(
p_cd_entidade in number,
p_dc_entidade in varchar2,
p_nm_entidade in varchar2,
p_cd_tipo in number,
p_id_status in char,
[code]........
I'm calling this code from C#, and I get an empty Result Set. What am I doing wrong? Can I output the dynamic sys_refcursor that I created? Below is my C# code using ODP.NET:
string pConnectionString = "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=ORASERVER)(PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=ORASID)));User Id=user;Password=password;";
OracleConnection oConn = new OracleConnection(pConnectionString);
oConn.Open();
string pNomeProc = "spfwdb_sl_entidade_1";

Im running the following query in DB - Prod2
select *
from t_act_rwrd_reimb_stay a
where reimbursed_amt < 0
and invoice_date = '01-JAN-1900'
and not exists ( select 'x' from t_act_rwrd_reimb_stay b
where a.GPM_ID_STAY = b.GPM_ID_STAY
and reimbursed_amt > 0 )
The above table t_act_rwrd_reimb_stay --> is from a view on the database Prod2 and this view is pulling the data from the database prod1 via dblink
When I run the same query on Prod1 it returns 3 rows. Is there any reason this is not fetching data on prod2 view? or whatz wrong with the above query
or for example if I run the above query as follows with the dblink "@prod1" it returns the data properly
select *
from t_act_rwrd_reimb_stay@Prod1 a
where reimbursed_amt < 0
and invoice_date = '01-JAN-1900'
and not exists ( select 'x' from t_act_rwrd_reimb_stay@prod1 b
where a.GPM_ID_STAY = b.GPM_ID_STAY
and reimbursed_amt > 0 )
I have this procedure
POSTCODE_TO_LAT_LNG_GM_API(postcode IN VARCHAR2, lat OUT NUMBER, p_long OUT NUMBER)
to convert a postcode into lat/long values. I then need to add them to the returned SQL statement so I used the string concat operator || with to_char but it comes up with this error when I try to apply the changes: Query cannot be parsed within the Builder. If you believe your query is syntactically correct, check the ''generic column'' checkbox below the region source to proceed without parsing.

I have a requirement to be coded like this:
A function to return pl/sql table(cant use ref cursor) whose columns varies every time it runs i.e,
means
type pl_tab_type is object(col1 varchar2(1000), col2 varchar2(1000))
type pl_tab is table of pl_tab_type
func f return pl_tab
as
...
end;
note : pl_tab_type will vary for each run of function f
i.e.,for example, pl_tab_type can be changed to as follows:
type pl_tab_type is object(col1 varchar2(1000), col2 varchar2(1000),col3 varchar2(1000))
how to return pl/sql table of dynamic type from func,
I'm attempting to use dynamic SQL to execute a function that returns a user-defined collection. The problem is that I don't know how to use dynamic SQL to handle user-defined types...or if this is even possible?
The code I have is as follows:
CREATE OR REPLACE PACKAGE qi_test IS
TYPE typ_qi_data IS RECORD(
iQIFlag NUMBER(1),
iIPFlag NUMBER(1),
iRiskIndicator NUMBER(1),
iDenominator NUMBER(8),
iNumerator NUMBER(8)
[code]........
I want to be able to execute the above function using dynamic SQL. Initially tried:
DECLARE
f2_data qi_test.typ_qi_data_tab;
BEGIN
EXECUTE IMMEDIATE 'begin :1 := qi_test.get_f2_data; end;'
USING OUT f2_data;
[code]......
...but this just produces "PLS-00457: expressions have to be of SQL types". So it looks like I can't do it this way if the returned data type is user defined. I know it would be easier in this instance to just use something like:
f2_data := qi_test.get_f2_data;
...rather than EXECUTE IMMEDIATE, but it's the principle that I need to get right as it forms part of a much bigger piece of work.
Just explaining what I am trying to achieve:
1) i have a hr.departments table that was loaded in hr schema on 1st oct 2012 with 4 columns(department_id, department_name, manager_id, location_id)
2) now I have a new schema by my name 'rahul' and I have loaded departments table but now an additional column has come into picture,ie created_date, this table got loaded on 1st-Nov-2012
3) Now going forward my columns could be dropped from the departments table (it can be a case), for example might be my departments table in my schema 'rahul' one day could comprise of only 3 columns(department_id,department_name,manager_id)
4) Now in the next step, I have managed to extract common column names(in a single line where columns are delimited using a comma) from both the tables(hr.departments and rahul.departments) which are (department_id, department_name, manager_id, location_id) using all_tab_cols table and I have written a function for it which i will be pasting below.
5) now going forward, using the above column names line with column names delimited using comma, I have used a ref cursor and assigned a query to it using the line of columns that I have extracted from the above point
6) Now I want to create a record variable which refers to my ref cursor, something like we do when we create a record variable by reffering to an explicit cursor defination that we give in the declaration block.
PS:
1) I have been out of touch with plsql for a long time so I have lost a lot of mmeory regarding plsql.
2) basically I need to compare data in hr.departments table with rahul.departments table for only columns that are common to both the tables, rest new or discarded columns information will go in one of the log tables that I have created(this is done already)
Code :

I have a table structure like :-
Create table test(A varchar2(50),B NUMBER);
The data in that table is like that:-
A B
----------------------
2*3
2*4*5
4*5
column B contain no data.
I want to create a function which can be used in a select query,and the output should come like that :-
A B
----------------------
2*3 6
2*4*5 40
4*5 20
Means column B contains the resultant value of column A.And the above output should come through a select statement.You can use any function inside the select statement.

I've just started with the Oracle SQL and come from a heavy MS SQL background and I understand that here are some natural differences in the syntax but I'm stumped as to why the following sql represents a problem:
update MASTERMICODES t1
set t1.TEMPTA = ( select t2.TAFCODE
from TA_FEATURES t2
where t2.FCODE = t1.FCODE
)
It returns Error report:

error:- single return sub query return more value.
how to write update join query base on multi[ple ow.
below query is returning two rows.The thing now happening is the query is returning the output for both the case statements.But what is need only when the first case staement is NULL then it should go for second case.
SELECT DISTINCT CASE
WHEN esc.x1 = Substr(inp.y, 0, 3)
AND esc.x2 = Substr(inp.y, 4, 2)THEN esc.cc
WHEN esc.mcc = Substr(inp.y, 0, 3)
AND esc.mnc = Substr(inp.y, 4, 3)THEN esc.cc

I tried using rownum=1 but it filters out valid records.correcting the above query so that if the first case is null then only it should go for second case.
I have the following query:
SELECT
d_dtm,
BTS_ID,
CASE WHEN D_DTM = (D_DTM-24/24)
THEN sum(V_ATT_CNT)

But it is not returning any results because of the "having" clause. I know it should return results because all I want it to do is in one column have the V_ATT for the current time period, and in the 2nd column, have the V_ATT 24 hours ago. I've checked the data and I should get results back but can't seem to figure out why this is not working...

I don't understand why the custid is the same for each customer, and why it's selecting every customer and not just those with more than 150 gallons ordered.
For this one use the oil tables that you set up and use a subquery. Select the minimum average fall use from the house table. Then show all customers whose number of gallons delivered times two is greater than the minimum.
I have a Strange requirement from client data is loaded from excel to Oracle Table- TST_TBL (with Header in Excel)
CREATE TABLE TST_TBL
(
JOB_DETAIL_ID NUMBER,
SHEET_NAME VARCHAR2(100 BYTE),
COL1 VARCHAR2(400 BYTE),
COL2 VARCHAR2(400 BYTE),
COL3 VARCHAR2(400 BYTE),
COL4 VARCHAR2(400 BYTE),

After the Data is loaded, we see data look like the above.
(1) Always COL3 column name have data value as 'Gen1' which is the indication for us from where data starts. But Gen1, Gen2, Gen3 etc... is dynamic. ie. This month we get gen1 and gen2 columns followed by null value in a column. Next month we get gen1,2,3,4 followed by null column.
(2) Null Column indicate us that there is a break in the column.
(3) Then next we need to look for next group of data (Monthly) and then insert into the same table again with different sheet_name column.
(4) Next for Quater and then YTD. None of the column Values are fixed and its all dynamic.
If you load the below data, you will come to know what i am looking for. I tried using UNPIVOT. But couldnt able to achieve it. Is there an option to do it in sigle query? or Do I need to go for Stored Procedure?
Insert into TST_TBL
(JOB_DETAIL_ID, SHEET_NAME, COL1, COL2, COL3,
COL4)
Values
(100, 'Wire_1', 'Gen1',
'Gen2', 'Gen3', 'Gen4');

Is it possible to define a cursor using dynamic sql. Reason being is, I want to fetch data from 4 diffrent tables but dont want 4 diffrent cursors for this purpose.
I have a procedure that takes an in parameter . Cursor is declared in this procedure.

writing dynamic sql query for swapping names:
the output shuld be like that

i have writen it in static form by using instr,substr.But i m having difficulty in making it dynamic by using select statement.I have to make it for retrieving data from database.
small piece of PL SQL code. how to make this query.Requirement is that a concurrent program is run with parameters and one of them i_num_org_id is non mandatory so it can come as NULL...Now in an existing code which i have to change, it uses a query as
SELECT xyz
FROM abc_table
WHERE <various conditions>
AND DECODE(i_num_org_id,NULL,1,table.organization_id) = NVL(i_num_org_id,1);
Now with the above way, if the program is run with some value for i_num_org_id or run as normal query (with NULL as the value) inside a PLSQL procedure/package then it runs fine.This query if you run in Toad etc then too it will work fine but if it is made a dynamic SQL and then used as either EXECUTE IMMEDIATE or opened as a cursor then we get a "Missing expression". I created this small anonymous block to test this and this will go into missing expression error
declare
l_num_org_id NUMBER := NULL;
l_temp VARCHAR2(100);
l_sql varchar2(1000);
begin
l_sql := 'SELECT '||''''||'abcd'||''''||'
[code].....
how i can reformat this query so that even if NULL value comes for i_num_org_id then it is handled.I am aware about CASE but that cannot be used in WHERE clause i guess.
I have a dynamic query that is ending up getting larger than 32k and this query is the base of a ref cursor that would in turn return the results to the application. How can I solve this problem since the largest content of a pl sql variable or literal is 32k ( said by oracle ) ?

It gives me an error on the line where the execute immediate statement is.
Quote:
ORA-00905
missing keyword
Cause: A required keyword is missing.

But when I check my stack trace table to see what the actual query string looks like, I see this
Quote:
SELECT sedol INTO l_attributed_sedol_code FROM integration.tmp_attributed_sedol WHERE CLIENT_LEDGER_REF='LEAE057090' AND ROWNUM=1
There's nothing wrong with that, is there? It executes fine if I try it manually.
I have a dynamic query which has this clause in it: WHERE [COLUMN NAME] IN (' || theString || ')
My problem is that theString is being passed in through a C# call and the variable is a bunch of strings concatenated together and separated by a comma. Ex: theString = "'val1','val2'"
How many quotes are supposed to go around val1 and val2?
I've tried the following and none work:
'val1','val2'
''val1','val2''
''val1'',''val2''
'''val1'',''val2'''
''''val1'',''val2''''
When I run the procedure in Oracle it works with '''val1'',''val2'''
I have written an SQL which will dynamically generate the Select statement with from and where clause in it. But that select statement when executed will get me hundreds of rows and i want to insert each row separately into one more table.
For that i have used a ref cursor to open and insert the table.
In the select list the column names will also be as follows: COLUMN1, COLUMN2, COLUMN3,....COLUMNn
find below the sample
TYPE ref_csr IS REF CURSOR;
insert_csr ref_csr;
v_select VARCHAR2 (4000) := NULL;
