SQL & PL/SQL :: Unable To Query Table - Fetching Data Timing Out?
May 1, 2011
User complaints fetching data from table A is timing-out ( as per application standards). I decided to collect latest statistics(dbms_stats) on index used by query which is running for more than 12 hours.not.It is partition table and got close to 10 millions records.
1) I checked dba_waiters - no rows
2) I checked v$locked_object/v$locks - no rows
3) I'm unable to run explain-plan for any criteria on that table
4) I'm unable to open table data-tab in Toad/ Sql developer.
5) I'm unable to query a single partition; no error but it keeps on running.
here i have a table called cn_wghmtdt_trn and some table columns are shift_date(date),net_wt(nothing but crushing weight or cane wt),crop_type_code(rotoon or plant),shift_code(its like 1/2/3 but its default 1)
Let us say, if i enter empno 10 (which is not there in database) in FIND Screen --> press FIND Button, it's showing up 'QUERY CAUSED NO RECORDS', Till this point it's working fine;. But after this, if i press CTR+F11 in block A, it's not pulling records. only this case it's not pulling records.
But if i enter something else in FIND Screen, if it returns any data, then if i press CTR+F11,it's pulling all records.
why it's failing to pull records if i try to query data in first case only.
I have dcs_sku table .The record count is 50 thousand in that table.My requirement is to fech every row,create an xml out of it and post the data to some third party.As the count is very huge,I can't select the entire record and do the operation at a time.way which I will run the sql query in a loop,which will fetch 1st from rown 1 to row 1000,next 1001 to 2000,2000 no 'n' row...
I tried the below query:
select * from dcs_sku where rownum between 1 and 200...This gave me the 1st 200 rows and worked fine.
but the moment I changed the query to :
select * from dcs_sku where rownum between 201 and 300:::No result was coming up.
--insert into t1(col1, col2, flag) values(1, 'a', 'Y'); --insert into t1(col1, col2, flag) values(2, 'b', 'N');
SELECT * FROM t1 x WHERE col1 = 1 AND col2 = 'a' -------------- condition1 AND 0 = -------------- condition2 NVL ( (SELECT COUNT (1) FROM t1 y WHERE y.flag = 'N' AND x.col1 = y.col1 AND x.col2 = y.col2),0)--=0
When remove NVL function or change the condition by having AND NVL(SELECT) =0 the query working fine.
I don't have any dba privileges, can you share a scripts which can tell how many block my query is fetching with or without indexes. How do i also get buffer hit, how can i get i/o without sql trace as i don't have access to dump_dest
I have a below query
SELECT DISTINCT ser_id AS STA_ser_id, rct_name AS STA_name FROM sd_servicecalls, rep_codes, rep_codes_text WHERE ser_sta_oid = rcd_oid AND rcd_oid = rct_rcd_oid AND rct_name IN ('New', 'Awaiting Approval', 'Approved', 'In Progress', 'Awaiting Supplier', 'Awaiting RFC', 'Awaiting Release', 'Pending Release', 'On Hold', 'Resolved', 'Implemented', 'Closed');
Does large hash value in explain plan mean more resource needed and more time to execute the query, How can i use ADDM for the above sql.
I am using Pro*C/C++ Release 10.2.0.2 in HP-UX. But Pro*C/C++ application was written long back during oracle release 8. Now we are facing a problem like EXEC SELECT query is not fetching the records even though record is present in DATABASE.
This is not happening every time. This problem starts happening only after heavy use of the unix process.
For every request, unix process will fetch the record and updates the same at the end and process goes to wait mode to get the request again. Let say after 50 request, process is returned with no rows found error.
It started working fine only after restarting the process and problem starts again after 50th or 60th request. This problem we are facing only after upgrade to 10g.
I have two different database servers where I need to migrate table data from one schema to another schema in batch wise for eg say 100 rows. I used BULK COLLECT with LIMIT. But to access BLOB data from table I have facing errors. What could be other approache to do the same.
here pc_work is a table containing BLOB data in sourse schema. I am fetch data from this table to table t1_test_work using dblink but not working
[ declare type array is table of test_work%ROWTYPE; L_DATA array; cursor C is select * from pc_work@prpctrg; begin open C; LOOP
I have a detailed block with a user ID column. The user name is not available in the block. Therefore, I have created a non-database column to retrieve the user name into it.
Here is the code I've used.
PROCEDURE get_details IS
iLoop number := 1;
CURSOR c is
SELECT FULL_NAME FROM GRP_EMPLOYEE WHERE EMPLOYEE_NUMBER = :USER_ID;
I want to insert XML data into my ( Oracle 11G Release 1 ) XMLType table using OCCI. I'm getting
ORA-01461: can bind a LONG value only for insert into a LONG column
My XML data size is around 1.5 to 2MB. I have also tried using setMaxParamSize before calling the setString method. But, still I'm getting the same exception.
I have one schema argus_app where there is a table cfg_enterprise. There is a view v$cfg_enterprisewhich selects data from cfg_enterprise and there is apublic synonym cfg_enterprise for v$cfg_enterprise.
When I login to argus_app and select from cfg_enterprise there is no data where as i log in to sys and select I can see data.
SQL> conn /as sysdba Connected. SQL> select enterprise_name from cfg_enterprise;
My job is running at 2 am and that time no application user is connected. Even though, my exp utility shows error on 3 tables (2 are temp tables), everyday. But when expdp is running without error, which was scheduled at 4 am.
Below are the error -

how to set the timing on for all SELECT statements in a procudeure...and i want that should come as a output for very SELECT statement slong with my original output.
Just want to know about archive log shipping time from production to physical standby. How can i know the timing that ARCHIVE LOG takes to reach from production to standby server.
I think we can get this through ALERT log but m not sure.
I'm facing a problem where I create a form and I want to feed time in "HH:MI" format, Firstly I choose the "Date" datatype, but during the feeding of time i.e "00:30", means if I want to feed only mints, then it doesn't accept, at the other hand if I feed "01:30" means mints with hr then it accepts.
To get rid of this problem I changed datatype "Date" to "Varchar2".
I create 3 columns on my form "TTL_WORKING_TIME" - "TTL_RUN_TIME" = "BRK_DWN_TIME". If I get any value in "BRK_DWN_TIME" column thn it has to be distribute in 3 or 4 reason of B/D, means if I get 00:30 mints brkdwn thn 00:15 mints for "reason1" and 00:15 mints for "reason2".
How I make calculation where I use "Varchar2" datatype.
my above table consists of two columnc sl_no and Status,col1 indicates the process no and the status indicates it is implemented or cancelled or failed during implementation.
i need to find the percentage of the implemented+cancelled process over failed..
test case: lets consider, A->count(Sl_NO) B->Count(STATUS) where STATUS='Implemented'
[Code]..
i think i have satisfactorily given enough data.. make it out using sql query..
Tablespace usage alerts are checked every ten minutes. You can request a check every minute when you set the threshold, and confirm that this has been set:
orclz>but you will still have to wait up to ten minutes for the alert to be raised. know whether this frequency can be changed? And why this particular alert behaves differently from all the others? This is the bahaviour in all releases since server alerts arrived.
