In a trigger(on update of a table t1) I am trying to write, I am doing an insert on t2 accessing ':new' values of the update on t1.
But in my Insert statement, I am having get one of the column values from another table. How can I write my insert statement in such a way as to insert values contained in ':new' pseudo columns and a select from another table. Below is my insert statement in the trigger : -------
IF (:old.GROUP_YELLOW <> :new.GROUP_YELLOW) THEN INSERT INTO TEST.W_THRESHOLD_LOG (THRESHOLD_LOG_WID, CHANGE_DATE, MEASURE_TYPE_WID, MEASURE_NAME, CUSTOMER_WID, CUSTOMER_NAME, USER_ID, CHANGED_ITEM, PREV_VALUE, NEW_VALUE) VALUES(TEST.W_THRESHOLD_LOG_SEQ.NEXTVAL, SYSDATE, :new.MEASURE_TYPE_WID, 'Rolling Stabilty' , :new.CUSTOMER_WID, 'Customer1', 'User1', 'GROUP_YELLOW', :old.GROUP_YELLOW , :new.GROUP_YELLOW); END IF; -------
In the above code if the hardcoded value 'Customer1' need to be picked from another table, i.e .
SELECT NAME FROM W_CUSTOMER_DIM WHERE CUSTOMER_WID = THRESHOLD.CUSTOMER_WID
how can I rewrite my query to the above value from the select into my insert statement..?
Is there any way to combine an identifier and select statement in PL/SQL when using the insert into command?
e.g.
DECLARE name := 'BOB'; BEGIN insert into mytable(NAME, SLOWEST_LAP, FASTEST_LAP) name, (select min(time), max(time) from lLAP_TIMES); END;
In the above statement I am trying to insert the identifier "name" (BOB) into MYTABLE.NAME, along with the result of the select query from the table LAP_TIMES ... min(time) into MYTABLE.SLOWEST_LAP, and, .... max(time) into MYTABLE.FASTEST_LAP.
If the above is possible in one statement how would I also combine an identifier, with two select statements into an "insert into" statement?
e.g.
name := 'BOB'; insert into mytable(NAME, SLOWEST_LAP, FASTEST_LAP, EVENT) name, (select min(time), max(time) from LAP_TIMES), (select race_event from MEET);
In the above example I am also trying to insert the result from MEET.RACE_EVENT into the column MYTABLE.EVENT
I am facing a problem in bulk insert using SELECT statement.My sql statement is like below.
strQuery :='INSERT INTO TAB3 (SELECT t1.c1,t2.c2 FROM TAB1 t1, TAB2 t2 WHERE t1.c1 = t2.c1 AND t1.c3 between 10 and 15 AND)' ....... some other conditions.
EXECUTE IMMEDIATE strQuery...These SQL statements are inside a procedure. And this procedure is called from C#.The number of rows returned by the "SELECT" query is 70.
On the very first time call of this procedure, the number rows inserted using strQuery is 70. But in the next time call (in the same transaction) of the procedure, the number rows inserted is only 50.And further if we are repeating calling this procedure, it will insert sometimes 70 or 50 etc. It is showing some inconsistency.On my initial analysis it is found that, the default optimizer is "ALL_ROWS". When i changed the optimizer mode to "rule", this issue is not coming.I am using Oracle 10g R2 version.
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.
how to insert data in oracle table without writing insert statement in oracle 9i or above. i am not going to write insert all, merge, sqlloder and import data.
In the following merge statement in the USINg clause...I am using a select stament of one schema WEDB.But that same select statement should take data from 30 schemeas and then check the condition below condition
ON(source.DNO = target.DNO AND source.BNO=target.BNO);
I thought that using UNIONALL for select statement of the schemas as below.
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 have one query i have create one table T1 in this table i have this three colm (EMPNO,ENAME,HIREDATE) and i have to insert raw from this two table T2 and T3 in T2 table colms are (EMPNO,SAL) and T3 table colm are (EMPNO,MGRID) so which query i have to run
I wanted to print 'null' when the column value is null. Actually, i am doing something like this
select empno||','||''''||ename||'''''||','||comm||','||sal from emp
It gives the following output for example 7369,'pointers',,200 If I use the above values to form a insert statement it throws an error. As 'comm' value is not there.
I wish to get something like 7369,'pointers','',200 or 7369,'pointers',null,200 from the above select query
note I dint copy paste the query exactly from my sql*plus session as I am away from my oracle machine
I read in a book that you can't use subquery in an insert statement . E.g:
1)insert into dates (date_col) values (select sysdate fom dual) but when i tried using subquery like this:
2)insert into regions values ((select max(region_id)+1 from regions), 'Oce');
This query worked but 1st query didnt.From my assumptions if we try inserting values in table with the subqueries for a particular column as in 1st query , it will throw error but not while inserting values in all columns as in 2nd query.
i'm executing a load test using the below statement:
INSERT INTO BPMBI.PPROCINSTANCE SELECT * FROM BPMBI.PPROCINSTANCE_BKP WHERE ROWNUM < 501; COMMIT; EXIT;
I've been using the same for a few days without any error while now wehn i try to use the same i get below error:
SQL> insert into pprocinstance select * from pprocinstance_bkp where rownum <= 500; insert into pprocinstance select * from pprocinstance_bkp where rownum <= 500 * ERROR at line 1: ORA-01858: a non-numeric character was found where a numeric was expected.
I've been trying to check what the issue is and when i execute the rownum < 140 works fine while rownum < 150 is showing the same error.
I have a table with unique index, and the application is doing inserts/updates into this table.Suddenly and for about half a minute I faced a high concurrency waits on all the processes running these inserts for one node. I saw this high concurrency wait in the top activity screen of the OEM only on one of the nodes. knowing that the processes doing these inserts are running on both nodes.
All what I have that in this half minute I see high concurrency wait in OEM top activity screen related to this insert statement and when I clicked on the insert I found high "enq: TX - index contention". Again this was only on one node.After this half minute everything went back to normal.What could be the reason and how can I investigate it ?
Given below a block of code, this code compiled successfully on one DB but returns error on other.DB version is same. I know sqlerrm can not be used directly but how it compiled successfully on one DB.
I am creating the following two tables...no issues here: CODECREATE TABLE COURSE_SECTION ( Csecid NUMBER(8) CONSTRAINT COURSE_SELECTION_NUMBER_pk PRIMARY Key, Cid NUMBER(6) NOT NULL CONSTRAINTS COURSE_SELECTION_Cid_fk REFERENCES COURSE, Termid NUMBER(5) NOT NULL CONSTRAINTS COURSE_SELECTION_Termid_fk REFERENCES TERM,
[code]...
The issue I am having is actually inserting data into the table: CODEINSERT INTO ENROLLMENT VALUES (100, 1000, 'A' ); INSERT INTO ENROLLMENT VALUES (100, 1003, 'A' );
[code]...
But I get an ORACLE error of
ORA-02291- integrity constraint (User1.ENROLLMENT_CSECID_FK) violated - parent key not foundHow can the parent key not be found when I have it declared/created in the above statement?
I would like to insert a value if that value is not existing in the table (example for a column which contains date only new dates should be inserted and if the date already exists in the column then it needs to get updated )
example of scenario...
date s1 s2 s3
in the above if the date is new..it should get inserted with the appropriate slot no.(s1,s2,s3) if the date already exists it needs to update the no.in slot no.
I want to grant a privilege through an insert statement into a sys table.Why do not grant the privilege through the classic way : grant select on t to l_user; ?
Because I want to do it remotely.I am connected to db1.I want to grant select on t2 to u2_b from u2_a.I assume that all DDL are DML. So a grant is equivalent "somewhere" to an insert.I tried to do my requirement locally, and here is the output.
SQL> conn scott/aa Connecté. SQL> -- step 1 : try to grant "normally" a select on dept to hr from scott SQL> grant select on dept to hr;
Autorisation de privilèges (GRANT) acceptée.
SQL> SQL> conn sys/a as sysdba Connecté. SQL> -- step 2 : Then, we connect to sys to see the row inserted in dba_tab_privs SQL> SQL> col GRANTEE format A10 SQL> col OWNER format A10
[code]...
Then if I can do it locally, I can do it remotely through a db link.
