I want to convert the below SQL to a dynamic sql to be executed from execute immediate statement.
UPDATE transaction SET loannum = lpad(loannum,12,'0')
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.
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;
[code].....
I have the following procedure body in a package.
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 want to execute a DML query with execute immediate statement. That DML query length exceeds 4000 characters. This query has Xquery related conditions, i can not split the query. when i tried execute it is giving "string literal too long". I tried with DBMS_SQL.Parse() and DBMS_SQL.Execute also, but it is giving same error. I have to execute this DML query inside a Procedure. We are using oracle 10g version
View 13 Replies View RelatedI'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.
I've seen this example numerous places, and tried to implement it, but I keep getting an "invalid identifier" error message, despite the fact that I've got the table and column specifically identified.For instance, my query reads like:
UPDATE tbl1
SET tbl1.EMPID =
(SELECT tbl2.EMPIDA FROM tbl2
WHERE LOWER(tbl1.EMAILCOL) = LOWER(tbl2.EMAILCOL2)
)
WHERE tbl2.EMPIDA IN ('Z1O435','S8M4722','M0D5156')
AND EXISTS
(SELECT tbl2.EMPIDA
FROM tbl2
WHERE tbl1.EMAILCOL= tbl2.EMAILCOL2 );
But I'll keep getting flagged at the tbl2.EMPIDA column reference. I have not tried this in SQL Plus, just in TOAD, but it seems to repeatedly fail.I have had to dump records to standalone Access tables and link back to perform the updates.
I am running one update statement which is running almost one hour still no response.
I would like to know either query is processing or hanging(suppose to finish the update within few minutes).
Is there any way or sql to find either the statement(my update query) is running or hanging.
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?
View 5 Replies View RelatedI want to know the DDL statements executed on a table. Example:
i have a table test1 with structure as below: test1 (aa number, bb varchar2(10))
After some period of time, one DDL statement to alter the column is issued.
alter table test1 modify (bb varchar2(30));
so new table structure is: test1(aa number, bb varchar2(30))
Basically i would like to find these 2 DDL statements executed on this table - test1, so that i compare which column get modified and what modification done.
Is this information stored in any data dictionary table?
note - audit, flashback option not enabled in this database.
If I like to identify the executed time of a particular SQL Statement, beside v$sql, is there any other dictionary or lookup table that have this piece of information?
Why v$sql is not sufficient, because this is a recurrsive update statement which is regularly called, and thus the last_load_time is overwritten.
My archivelog had been purged due to our scheduled backup.
Is there any other way to identify when the particular SQL statement is executed?
create table myex(qid number, lid number, myname varchar2(20), status varchar2(30));
insert into myex values(1,1,'uu',null);
commit;
CREATE OR REPLACE PACKAGE mypack
IS
PROCEDURE p_get (in_qid myex.qid%TYPE, out_mycur OUT SYS_REFCURSOR);
end mypack;
/
[code].....
Note the one record in the table does not satisfy the cursor query criteria, So I try to pass in 1 to see what happens.
In sqlplus:
var out_mycur refcursor;
begin
mypack.p_get(1,:out_mycur);
end;
/
print out_mycur;

why is this procedure with EXECUTE IMMEDIATE not working for me, when I pass a dynamic string to it.
this is the proc:
CREATE OR REPLACE FUNCTION MIGRATION.execute_sql (pSQL varchar2) RETURN varchar2 IS
vResult Varchar(200);
BEGIN
vResult := null;
[code]......
and when I invoke it like this it's fine:
select execute_sql ('select sysdate from dual') test from dual. However, when I try something like this, it won't work:
select execute_sql ('select max(al_code) from alert_log where al_user= '||user) test_sql from dual
the error message I get is:
ORA-00904: "MIGRATION": invalid identifier

This is my query:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
[Code]...
The problem I am having is that it is updating all rows even when it is pulling back a null value for b.sak_request. I've tried adding b.sak_request is not null to the select statement like this:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
WHERE b.nam_eds_tracking_id = c.id_dir_track_eds
[Code]...
but it doesn't seem to make a difference. The reason I need to do this is that the difference between where it matches with a valid (non-null) value is 396 rows vs. 12,484 rows which is too time consuming to run on my page.

reconciliation logic using Oracle
Version
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
PL/SQL Release 10.2.0.4.0 - Production
CORE 10.2.0.4.0 Production
TNS for Solaris: Version 10.2.0.4.0 - Production
NLSRTL Version 10.2.0.4.0 - Production
Current written logic for reconciliation:
1. Load data from source_a in a staging table using date filter
2. Load data from a file (Source_B) in temp table
3. Algo for reconciliation:
fetch value from source_B and if an entry exists in source_a then match say 10 columns if they match update reconciliation_oke = TRUE
there is an and written for testing all the 10 columns There is report generated out this which shows non matched columns and the entries which are missing....Now the requirement is to modify the logic in a way which shows which all columns are mismatched on the report in case present.
Since there are around 10 thousand records which would be reconciled on a daily basis, performance also needs to be taken care of...I guess i would be required to use PL/SQl tables...
