I am trying to perform a dml operation(insert) to insert data into a table. I created a procedure in which a insert statement is generated. In another procedure I am trying to execute this auto generated statement using execute immediate. For that I created 2 variables . First one contain the insert statement and other one contain the list of columns. I m passing these strings to execute immediate like this
Execute Immediate(v_query) using(v_col_list)
after execution i m getting the following error
ORA-01008: not all variables bound
ORA-06512": at ' db_name.load_data' , line no 217
but when i tried it with list of column into using clause it is working like
Execute Immediate(v_query) using col1,col2,col3
I have more than 150 tables in the schema and i am creating a single procedure to load the data into base tables by using external tables. By passing the table name to procedure it generates the update and insert statements but i am getting error while executing the statements with dynamic sql.

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...

Is it possible to create sequence using EXECUTE IMMEDIATE statement. The sequence name will be the bind variable.
DECLARE
TEMP VARCHAR2(20);
BEGIN
TEMP := :P2_INFO;
EXECUTE IMMEDIATE 'CREATE SEQUENCE' TEMP;
END;
This creates a sequence named TEMP, but i want the name :P2_INFO entered by user.

I'm trying to write a simple query so I can do some testing on my application. I am trying to do something like this:
SELECT
Location,
LEVEL,
FROM
S_ORG_EXT
where
Location = 'North America' and LEVEL ='Software'
OR location = 'North America'
and Active = 'N'
in the where statement, I have put in the 'Active' that isn't a column. I want to be able to be able to change that in the select part. But I am not able to do so.
this is what I have tried:
SELECT
Location,
LEVEL,
Active = 'N' --I want to change this in the to N or Y so I can get different results.
FROM
S_ORG_EXT
where
Location = 'North America' and LEVEL ='Software'
OR location = 'North America'
and Active = 'N'

am new to oracle based coding and am having a heck of a time trying to figure this out. Basically i need to declare 2 date variables, Begin date and End Date.
I then need an if statement that says if begin date = 0 or is null then set it to the first day of the previous month. and if end date = 0 or is null then set it to the last day of the previous month.
So for today 5/26/2010 i would need
begin date = 4/1/2010
end date = 4/30/2010
I have searched and tried but so far to no avail.

I have a procedure as below. To sum up the procedure in one line it dynamically forms a string to get the values of the type which is passed as an input to the procedure.
I call the procedure as
exec exec_imm( exec_imm_t(1,'asd','1/2-34'));
ERROR:
Error starting at line 9 in command:
exec exec_imm( exec_imm_t(1,'asd','1/2-34'))
Error report:
ORA-00904: "P_TYPE_DATA"."ADDRESS": invalid identifier
ORA-06512: at "PTK_ADM.EXEC_IMM", line 26
ORA-06512: at line 1
00904. 00000 - "%s: invalid identifier"
NOTE:
When I try to execute the procedure with the execute immediate statement I get the above error. But when I execute the select statement which is nothing but the value in v_type_data directly (as seen in the comments in the code below) there is no error. But when the same v_type_data is used in execute immediate, I get an error.
CREATE OR REPLACE procedure exec_imm(p_type_data exec_imm_t)
AS
v_type_str CLOB := NULL;
v_type_data CLOB := NULL;
v_type_name VARCHAR2(25) := NULL;
BEGIN

here is what i am trying to do: im as using oracle 8 with sqltool
i have a Very large query. and i notice that many things are repeating. so i want to add them to a variable, instead of re-typing them. for example:
select SomeID from SomeTable;
i want SomeID to be put into a variable. but i still want to be able to get a normal select query at the end so that i can see the returned value:
i tried things like:
declare x number;
begin
set x=45454
select x from SomeTable;
end;
but could not get it to work.

I have a problem that i have hard coded the username.tablename in each select statement of all forms of my application. Now i want to use a dynamic variable in place of username in each select statement throughout the application. The example is:
select * from scott.emp
and i want to write it as:
select * from variable.emp
But at compilation of the form the compiler should know the above variable name.
I have tried to use following select statement but it does not work.
select user into :global.username from user_users
I think perhaps my problem would be solved with Dynamic SQL Statement but i have no experience by using this statement.

I would like to know what happens when we fire:
grant all on any table to user_name;
and
grant all on table_name to user_name;
Actually I was performing "grant all on table_name to user_name;" to grant the privilege but 1 of my friends suggested "grant all on any table to user_name;"

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.

I am using JDBC to run a few queries from my Java program (multi-threaded one).I am facing an issue where a select statement is blocking a delete statement. From the java code point of view, there are 2 different threads accessing the same tables (whith different DB connection objects).
When the block occurs (which i was able to find out from the java thread dump that there is a lock on oracle), the below is the output:
SQL> SELECT TO_CHAR(sysdate, 'DD-MON-YYYY HH24:MI:SS')
2 || ' User '||s1.username || '@' || s1.machine
3 || ' ( SID= ' || s1.sid || ' ) with the statement: ' || sqlt2.sql_text
||' is blocking the SQL statement on '|| s2.username || '@'
4 5 || s2.machine || ' ( SID=' || s2.sid || ' ) blocked SQL -> '
6 ||sqlt1.sql_text AS blocking_status FROM v$lock l1, v$session s1, v$lock l2 ,
7 v$session s2,v$sql sqlt1, v$sql sqlt2
8 WHERE s1.sid =l1.sid
9 AND s2.sid =l2.sid AND sqlt1.sql_id= s2.sql_id
AND sqlt2.sql_id= s1.prev_sql_id AND l1.BLOCK =1
10 AND l2.request > 0 AND l1.id1 = l2.id1 AND l2.id2 = l2.id2;
[code]...
From the above it can be seen that a select statement is blocking a delete. Unless the select is select for Update, it should not block other statements is not it ?

I am trying to use execute immediate in a trigger. See the below example
create table test_tbl(col1 number,col2 varchar2(10), col3 date);
create table test_tbl_log as select * from test_tbl where 1 = 2;
create or replace trigger test_trig
after insert or update or delete on test_tbl
for each row
declare
v_str varchar2(4000);
[code].......
insert into test_tbl values(3,'test',sysdate);
I got the Error : -1008->ORA-01008: not all variables bound
In the execute immediate statement if I change the v_using_str variable to :new.col1,:new.col2,:new.col3 trigger is running fine. But here I have to create trigger on all the tables in my schema and I dont want to list all the column names for each table manually and I am using a for loop to build the v_using_str string in my original code.
