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'm using pivot query feature of oracle 11g and came across a strange situation where i need to pass a "select statement" in a "in clause" of pivot query.
I have tried with pivot xml but it not giving desired output in sql*plus session.It is giving unreadable output.
select * from (select uin,testing_id,pfa_result from test1) pivot xml (max(pfa_result) as result for (testing_id) in (select distinct testing_id from test1));
[code]....
Here actually i want to use "select distinct id from test1" instead of "in (11,12,13,14,15)". Because i don't know how many id's will be there and of which values. e.g. 11 or 21 or 25.
currently i m going through some dumps for my OCA-11g prep.I came across one sentence :A view cannot have an ORDER BY clause in the SELECT statement.well this statement is false and the explanation given was :
Query operations containing ORDER BY clause are also permitted, so long as the ORDER BY clause appears outside the parentheses.
The following is an example of what I mean: CREATE VIEW my_view AS (SELECT*FROM emp) ORDER BYempno.
but when i tried running the query like this :CREATE VIEW my_view AS SELECT*FROM emp ORDER BYempno ,it worked w/o giving parentheses.
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
Is it possible to insert a table in case of exceptions. For example, i have a function like this:
Create or replace Function test_function(p_Parameter_ID number) Return number is
l_Variable number; Begin Select output into l_Variable from test_table where id=p_Parameter_ID; Exception when others then Insert into exception_Table values('No Data Found', p_Parameter_ID); return l_Variable; End test_function;
In this function, if you notice, i wanted to populate an exception table for further analysis in case data is not found. The function gets compiled without any error in this case.However when i execute this and the Select query does not return any output for a particular parameter_ID, then the exception part fails. It gives me an error "cannot perform a DML operation inside a query".
Can't i write insert statements inside the exception section?
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.
I HAVE 2 BLOCKS E.G. MASTER-DETAIL AND i have created it manually then how to insert values thrugh these blocks using a button called "save" using "commit_form;" suppose form fields are
master-block: emp_id emp name age detail block: address city where emp_id is primary key as well foreign key in detail table
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.
how can i enable user to select and save any document into oracle database and later on choose to retrieve and display it.it should be like windows file open save.
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 ?
select empno,ename,deptno,employee_status from emp,dept where emp.deptno=dept.deptno and ( employee_status in(Case employee_status when {?Status}=1 then 'A' when {?Status}= 2 then 'T' When {?Status}= 3 then 'A'||','||'T')) OR ( end_date >= {?START_DATE} AND end_date <= {?END_DATE} ) )
Since when i pass employee_status as input 1 it have given me 4 records. When I pass employee_status as input 2 it have given me 3 records. When I pass employee_status as input 3 it should give me 4 records + 3 records=7 records.
4 records for employee_status 'A' 3 RECORDS for employee_status 'T' 7 records for employee_status 'A' AND 'T'
Want to filter a data using CASE statement in WHERE clause for the following scenario.
Need to Filter tb1.fallback_keyword if the fallback_flag is "Y' or 'N' and pg_number is null.Else no partial search of keyword.
where CASE WHEN (fallback_flg = 'Y' OR fallback_flg = 'N') and (pg_number is NULL ) THEN tb1.fallback_keyword = SUBSTR(key_word,1, INSTR(key_word,'#',-2)) ELSE (tb1.keyword = key_word ) AND (tb1.keyword like regexp_replace(key_word, '[*]+', '%')) END
Are some posibilities to exclude duplicate values do not using sql aggregate functions in main select statement? Priview SQL statement
SELECT * FROM ( select id,hin_id,name,code,valid_date_from,valid_date_to from diaries )
[Code]....
In this case i got duplicate of entry TT2 id 50513 In main select statement cant use agregate functions are even posible to exclude this value from result modifying only the QLRST WHERE clause (TRUNC need to be here)
Is it possible within a CASE statement to put conditions on the date range that I want to pull? IE: am versus pm. The query has to pull specific time ranges for an AM run versus a PM run. ..... FROM table WHERE CASE WHEN TO_CHAR(SYSDATE,'AM') = 'AM' THEN table.date BETWEEN TRUNC(SYSDATE) AND SYSDATE ELSE table.date BETWEEN TRUNC(SYSDATE+12/24) AND SYSDATE
