SQL & PL/SQL :: Using Dbms_sql.execute To Build / Execute Dynamic Sql?
Oct 23, 2013I'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.
SQL & PL/SQL :: Execute Immediate Doesn't Like Dynamic String
Feb 29, 2012why 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
ORA-06512: at "MIGRATION.EXECUTE_SQL", line 26

SQL & PL/SQL :: Procedure Cursor For Loop Don't Execute

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.

Execute Immediate In Trigger
Apr 17, 2013I 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.

SQL & PL/SQL :: How Many Times Do The Inner Execute
Oct 2, 2010I found this query in one of my stored procedures that updates a key for a value in a data table by reading the information from a master table.
The data table is: ITEM_INVENTORY
The master table is: MASTER_SOURCE_SYSTEM
UPDATE ITEM_INVENTORY I
SET I.SOURCE_SYSTEM_ID =
(SELECT NVL(M.SRC_SYS_ID,-100)
FROM MASTER_SOURCE_SYSTEM M
WHERE M.SRC_SYS_DESC(+) = I.SOURCE_SYSTEM_CODE )
WHERE ORG_CODE = 'TNXC'
AND EXISTS (SELECT 1 FROM MASTER_SOURCE_SYSTEM M
WHERE M.SRC_SYS_DESC(+) = I.SOURCE_SYSTEM_CODE )
The situation here is that:
1. There are about 15000 rows that match ORG_CODE = 'TNXC'.
2. The SOURCE_SYSTEM_CODE is same for all the 15000 rows and there is a matching entry for it in the MASTER_SOURCE_SYSTEM table.
My question is: Do both the inner select statements execute 15000 times?
The statement executes within a second and updates 15000 rows. How is this made possible?

View 39 Replies View RelatedSQL & PL/SQL :: How To Use VArray In Using Clause Of Execute Immediate
Sep 23, 2010I'm trying to optimize an application running heavy updates/inserts/deletes, by having it using bind variables instead of "string queries".
The columns to be updated can vary (possibly from one column to all columns of a table), thus I have made som logic to build the query accordingly. My problem is now that I cant get the EXECUTE below to handle the VARRAY passed in the USING clause, it fails with "PLS-00457: expressions have to be of SQL types"
Environment:
create table table_x (a varchar2(10),b varchar2(10),c varchar2(10),d varchar2(10));
insert into table_x values('a','b','c','d');
commit;
Code, simplified with static number of columns:
declare
type v is varray(10) of varchar2(20);
v_values v:=v('A','B','c');
myupdate varchar2(2000);
begin
myupdate:='update table_x set a=:a, b=:b where c=:c';
dbms_output.put_line(myupdate);
execute immediate myupdate using v_values;
end;
I've understood that I cannot send TABLE type variables by USING, but this should be an VARRAY.
