SQL & PL/SQL :: Execute Dynamic Query Stored In Table?
May 27, 2011
I want to execute a dynamic query which is stored in a Table.
Output of that query should be stored in database server.
Is there any way i can create a dynamic procedure? I have created a sample code but issue is i cannot make the below data type dynamic as per the query.
en com_fund_info_m%ROWTYPE;
CREATE TABLE TEMP (SQLSTATEMENT VARCHAR2(100))
DECLARE
TYPE r_cursor IS REF CURSOR;
c_emp r_cursor;
en com_fund_info_m%ROWTYPE;
PROCEDURE getrecordsForinspection(i_table_name in varchar2, i_thread_id in varchar2, i_max_count in number default null, o_results out sys_refcursor) AS v_sql varchar2(1000):= null;
begin v_sql := 'update '||'i_table_name||' set status = '||'''IN_PROCESS-'||i_thread_id||''''||' Where final_status = '||''''STATUS_ACCEPTED'''||' and ('||i_max_count||' is null or rownum <= '||i_max_count||');';
EXECUTE IMMEDIATE(v_sql); commit; end;
when I execute the above procedure it gives the following error.
ORA-00911: invalid character cause: Identifiers may not start with any ASCII characters other than letters and numbers.$#_ are also allowed after the first character. Identifiers enclosed by double quotes may contain any character other than a double quote. Alternative quotes(q'#....#') can not use spaces, tabs, or carriage returns as delimiters. For all other contexts, consult the SQL language reference Manual.
I think dynamic sql is not executed because of the pipe character in the sql statement.
I'm working with old code that uses dbms_sql.execute to build/execute dynamic sql. In our case, the user can select varying columns(I think up to 20) with different where conditions as needed.
After building the sql, here's an example
WITH ph AS (SELECT ph.* FROM po_header ph WHERE 1 = 2), pf AS (SELECT DISTINCT pf.order_id, pf.fund FROM po_fau pf, ph WHERE 1 = 1 AND ph.order_id = pf.order_id
[code]....
Where table records for
po_header = ~567746 po_fau = ~2153570
and PK "order_id" is a NUMBER(10) not null and a snippet of the code looks like
nDDL_Cursor := dbms_sql.open_cursor; dbms_sql.parse(nDDL_Cursor, sSQLStr, 2); FOR x IN 1 .. nCols LOOP sCols(x) := ''; dbms_sql.define_column(nDDL_Cursor, x, sCols(x), 100); END LOOP; nError := dbms_sql.execute(nDDL_cursor);
why when the "execute" statement is fired off the elapsed time takes ~4.5 seconds but If I change "1 = 1" above to "1 = 2" it takes ~.2 seconds. If I run the above query interactively it takes ~.2 seconds. Shouldn't the above query when joining
ph.order_id = pf.order_id
return zero rows back instantly or does the "dbms_sql_execute" do some other type of parsing internally that takes cpu time.
We can execute dynamic sql using both execute immediate and ref cursor..But what is the difference between the two and performance-wise which is better?
I will have to take the Employee Names and create a table structure. Number of employee names can vary from day to day. So, whenever I execute my procedure with Table type, I will have to build the table columns with the employee names.
Requirement is to build procedure where it has 10-12 input variables but some of them (input variables) may at times be NULL.Based on this, i thought of getting into EXECUTE IMMEDIATE but this would just return rows i mean DML stmt for EXECUTE IMMEDIATE.Also, on the requirment is all parameters are present then result set be based on range on start and end date.
CREATE OR REPLACE PROCEDURE SCOTT.GetEmpList(p_recordset OUT SYS_REFCURSOR) AS BEGIN OPEN p_recordset FOR SELECT * FROM scott.emp WHERE deptno=10; END GetEmpList;
Now i would like to execute this procedure in sqlplus which will display the following:
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO 7782 CLARK MANAGER 7839 6/9/1981 2450 10 7839 KING PRESIDENT 11/17/1981 5000 10 7934 MILLER CLERK 7782 1/23/1982 1300 10
I would like to use dynamic sql for an select query with where clause and then use the dynamic sql in pl/sql stored procedure. how to create dynamic sql (select query) and how to use it in pl/sql stored procedure.
I just started to play with this system and don't understand how to execute the the stored procedure (that creates report) from the APEX page. I know that they have sample documentation and java script call (show below):
<script language=”JavaScript” type=”text/javascript”> function callMyRep() { var formVal1 = document.getElementById(’P_PAR1′).value; var url; url = ‘rep1?p_session_id=&SESSION.’+'&p_par1=’+ formVal1; window.location.href=”f?p=&APP_ID.:12:&SESSION.”; w = open(url,”winRep”,”Scrollbars=1,resizable=1,width=800,height=600″); Close here. X [code]....
In this example rep1 is the stored procedure that creates report.How can I execute it using url?
I would like to create a trigger that will execute a stored procedure when a package/function/procedure is compiled. I tried creating an update trigger on user_objects, but it statues aI cannot create that trigger tyoe on views.
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.
I currently have a form and when I am logged in as the owner the execute query button can be performed. But when I try and do this with another user the query cannot be executed. I have granted the users with the correct privileges. I am now trying to re-create the data block but with using the synonym but the synonyms cannot be found.
I've used a date in execute immediate query in function, but at the time passing the date as input parameter and getting the result i'm getting following error.
SQL> select getstockqty(1,to_date('31/03/2012','dd/mm/yyyy')) from dual; select getstockqty(1,to_date('31/03/2012','dd/mm/yyyy')) from dual * ERROR at line 1: ORA-01858: a non-numeric character was found where a numeric was expected ORA-06512: at "MIS.GETSTOCKQTY", line 11
I have designed a form in which there are two datablocks one contains the major details and the other contains details saved under that record. And it is working properly. If you are not getting then take an example of department and employee datablocks, first contains the info of department and second contains the employee info working in that department.
now what i want to do is to make the life of user easier, as the records are displaying properly so if user want to know that this record is present in the details of that header so while scrolling all records can he search by putting some info in the detail block to get that result while remaining on the same datablock?
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'); Insert into TST_TBL
