I have an app that reads records from a driver table in order to update another (account) table. The idea is that it runs quickly but does not impact other processes on the system. In total I have around 1M records to update.
Originally I wanted to BULK COLLECT and employ a LIMIT of 1000 with a FORALL. The problem with this approach though is that I make two updates. One to the target table but I also need to update the driver table showing that I have processed the record. Therefore I cannot use this option to commit every time I reach the LIMIT by having a COMMIT inside the LOOP.
So instead I I have a FOR LOOP and test the count, if it is 1000 then I want to commit. I thought this syntax would be fine but I get the 'Fetch Out of Sequence' error. Below is a copy of the code.. Is this being caused by the double update... as the format of the code looks correct to me (though it is late!!)?
PROCEDURE update_set IS CURSOR cur_get_recs IS SELECT account_num, ttw_active_flag, acct_rowid, rowid driver_rowid FROM driver_table FOR UPDATE OF processed; [code]...
I am trying to update a table column values if any change occurs using bulk collect and for all update not able to get idea. below is the proc working out.it is for insert and update using the cursors.
CREATE OR REPLACE PROCEDURE PRC_INS(P_ID IN NUMBER,P_STAT OUT NUMBER) IS TYPE T_TEST_TAB IS TABLE OF T_DTLS%ROWTYPE; V_PARAM T_TEST_TAB; V_STATUS NUMBER; V_BUS VARCHAR2(20); V_UP VARCHAR2(1); V_Q VARCHAR2(50);
Table contains 10k records,we are going to insert data into another table with FORALL bulk collect limit 1000. if i use 10000 ,it's completed fast compared to 1000 limit.Can u tell me which one is better Limit.
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?
CREATE OR REPLACE PROCEDURE IND_MONITOR(P_tab VARCHAR2) is type ind_table is table of varchar2(20); p_ind ind_table; v_sql varchar2(2000); begin select index_name bulk collect into P_Ind from user_indexes where table_name=upper(P_tab); for i in 1..p_ind.count loop v_sql :='alter index '||p_ind(i)|| ' monitoring usage' execute immediate v_sql using p_ind(i); end loop; end;
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.
I 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?
set serveroutput on declare a int; begin execute immediate 'select employee_id from employees where first_name=:ab' into a using 'Donald' ; dbms_output.put_line(a); end;
but this one doesn't
set serveroutput on declare a int; begin execute immediate 'select employee_id into :1 from employees where first_name=:2' using a,'Donald'; dbms_output.put_line(a); end;
Am I not allowed to specify a bind variable with an into clause inside execute immediate ?
creating package and i need not to use execute immediate. There are some dynamic build plsql's and sql's stored in global lists. Any other possibility to run them without execute immediate?
If I use DBMS_METADATA.GET_DDL and DBMS_METADATA.GET_GRANTED_DDL for a particular user I can get something like this:
CREATE USER "USERB" IDENTIFIED BY VALUES 'B6C9E444D14CDE5B' DEFAULT TABLESPACE "PROD_TBSP_03" TEMPORARY TABLESPACE "TEMP"; GRANT "SELECT_CATALOG_ROLE" TO "USERB"; GRANT "SCHEMA_ROLE" TO "USERB";
Now, how do I go executing this in pl/sql? The following would fail as execute immediate wouldn't run all of these at the same time:
DECLARE v_str VARCHAR2(4000 BYTE); BEGIN v_str := 'CREATE USER "USERB" IDENTIFIED BY VALUES ''B6C9E444D14CDE5B'' DEFAULT TABLESPACE "PROD_TBSP_03" TEMPORARY TABLESPACE "TEMP";' || chr(10) || 'GRANT "SELECT_CATALOG_ROLE" TO "USERB";' || chr(10) || 'GRANT "SCHEMA_ROLE" TO "USERB";'; dbms_output.put_line(v_str); EXECUTE IMMEDIATE v_str;
I created a procedure with four in parameters and 1 out parameter is there in this i want to check if any parameters is null or any two parameters are null or any three parameters are null...like this i checked(16 conditions) for all combinations i put if conditions but can i use execute immediate instead of all 16 conditions?
I've been asked to look into ways I an execute an application with a trigger. I know I could set some database flag and have an application look at the flag and execute an application based on this, but my boss really doesn't wanna go down this route.
I was told I can use either C or java within the trigger somehow to execute an application (for example notepad.exe)
I am trying to execute an UPDATE from a field that may have more than row. I get ORA-01427: single-row subquery returns more than one row.
I need to set the careof column in owner table to hold the name (NAM) from the alt table if the alttype from alt is ATT. We could have more than one id and the careof names can be different.
This is my query:
UPDATE owner s SET s.careof = (SELECT a.NAM FROM alt a WHERE a.taxyr = '2011' AND a.alttype = 'ATT' AND a.card in ('0')
I am facing a problem regarding the execute immediate command. I have created a procedure as given below
SQL> set echo on ; SQL> set serveroutput on; SQL> declare 2 l_var varchar2(50); 3 sqlstring varchar2(3000); 4 begin [code].......
In this procedure the execute immediate command shows error ( if i avoid exception).I have tried other syntax too of this command but it is showing error only.
I have a dynamic query which i want to run till it return zero records.
I am using WHILE loop for that but it is giving compilation error:
The query is
execute immediate ' Delete from tbl_archive_trade_list where deal_id in ( select deal_id from tbl_archive_trade_list where trade_id in ( select trade_id from ' || main_trade_group_table || ' where tradegroup_id in ( select tradegroup_id from ' || main_trade_group_table || ' a , tbl_archive_trade_list b
[Code]...
I want to run this Query in While loop till the above command return 0 records.
I tried giving the above statement inside WHILE loop but it is failing.
Without the WHILE loop the above statement works fine and executed properly.
I'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.
I am using database version Oracle Database 10g Release 10.2.0.1.0 - Production. I have multiple schema's in my database and want to read the data from multiple schema's and have to insert into a single table. For that i was thinking to pass the schema name as parameter and fetch data accordingly. While creating procedure i got the below mentioned error, yet i haven't got any result on this.
ORA-00936: missing expression ORA-06512: at "INTERNATIONAL.MPLS_PROC_TEST";, line 66 ORA-06512: at line 15
following is my procedure
CREATE OR REPLACE PROCEDURE MPLS_PROC_TEST ( P_CLIENT_CODE IN VARCHAR2, P_VARIANT_CODE IN VARCHAR2, P_START_DATE IN DATE, P_END_DATE IN DATE, P_MEDIA_CODE IN VARCHAR2, P_SCHEMA IN VARCHAR2 [code]........
