I am new to oracle programming.
I have a statement below
The statement below correctly filters the records that I require.. I now want to;
Count the number of records that meet the criteria and Delete the records that meet the criteria
select
sl.project_code,
sl.COST_code,
sl.category_code,
sl.supplier_code,
[Code]....
I want to count the batch records using BATCH_ID with CASE statement ,for that i am using below query but its not working ,
SELECT COUNT(*) FROM <TABLENAME> WHERE VNBATCH_ID=CASE WHEN #SDC <10 AND #PERIOD >=10 THEN
0||#SDC||#PERIOD||#BATCH_ID
WHEN #SDC <10 AND #PERIOD <10 THEN
0||#SDC||0||#PERIOD||#BATCH_ID
WHEN #SDC >=10 AND #PERIOD <10 THEN
#SDC||0||#PERIOD||#BATCH_ID
ELSE
#SDC||#PERIOD||#BATCH_ID
END
One of the procedures that am working on is failing with ORA-0000: normal, successful completion error.
The procedure has got several update and delete statements and have logging enabled after each step. The problem with that again is, each time the log table gets updated thereby losing the history of until what point the procedure ran successfully.I have this issue only in production environment and unable to simulate it in dev environment which limits my options of troubleshooting the procedure code. I was using SQLERRM in the code.
Is there a way I can identify the bad records/ record causing this issue? Am very new to PL/SQL and do not know how to proceed with this.How do you debug this sort of issues??(where one procedure internally invokes another one which again invokes other one etc)
Why large delete statements, with no where clauses, could be using up temp tablespace segments? I thought temp tablespace was just for sort operations,joins, etc.
We have a weekly job that inserts rows into a staging table, deletes, with commit, the a few minutes later and repeats the process. Each delete is using some of the temp tablespace. Eventually we run out of space (ora-01652). That's another thing. I would have thought the space would be released for the next process, but it's now.

We will probably switch to truncate statements, but this situation really puzzles me. I've tried view the docs but don't see any of delete statements using temp tablespace.
I have a table A which has million records, and one of the column is a date. All records prior to 01-FEB-2009 should be deleted.
I cannot run the below code considering the amount of records or rows in the table A.
Begin
Delete from A where trunc(date_column) < '01-FEB-2009';
commit;
End;
where we can delete the rows prior to 01-FEB-2009 and also have a total count of how many were deleted?
I have one table that have many records. For the maintenance purpose I like to delete old record based on Customer No.-That is Mobile NO.If each Customer have more than 300 records, I like to delete by everyday batch process.can't figure out how to apply each Customer No.(Specific Column), I could sort (order by few column - SAVE_DT or SMS_ARV_CLC) how to write this kind of query? I try rownum but no more progress.

I like to increase speed to delete our table. Is it possible to use BULK COLLECT or FORALL this query? This is not single delete or select, maybe I got the error? Is it possible to use BULK method to this query?

Can we execute more than one insert statements at a time (eg 10) in database and givecommit at the end of insert statements or else give a commit one by one after each insert statements ?

View 9 Replies View RelatedWhen we execute select count(*) from table_name it returns the number of rows.
What does count(1) do? What does 1 signifies over here? Is this same as count(*) as it gives the same result on execution?
difference between count(1) and count(*). As i know count(*) will give number of rows irrespective of null and count(1) will not count the null.My Oracle version is 10 g.

I know, importing a *.CSV-table is easy using a few clicks with the GUI, but I want to know, how to import and create new tables, using the existing *. CSV-files, with SQL statements.
how to import a .CSV-file using SQL-statements?
I have a column in a database that contains both numerical and char data. I would like to be able to do two different things (two different queries)
1. divide the numerical data in the column by 10 and leave the char data alone (just return it)
2. detect the numerical data in the column and treat is as a different value so I can run averages & counts on it while disregarding the char data
I'm not at all sure how to do number 2. I thought a CASE statement would work for number 1, but then I realized CASE doesn't like different datatypes:
select
case when '1234' = 'checked' then 'checked'
when '1234' = 'gen.nograde' then 'gen.nograde'
when '1234' = null then null
else '1234'/10 end as "GRADE"

From database server, I need to monitor the details about the sql statements which are being currenlt running in client machines.
I tried with V_$SQLTEXT view where I can only see the SQL statements, hash value,address,SQL_id. but I'm not able to get the user name,name the client machine .

I have a question regarding the SQL statements embedded behind the Self Service Pages in Oracle Applications.
Taking an example of Oracle E-business Suite, Is there a way to check what SQL statement is hard coded or embedded in a particular required Self Service Page?
I'm in a bit of a pickle with some SQL syntax, and while my Oracle-fu is weak, an associate with SQL skills is also stuck. I am developing a database for my department that is backed by Oracle Enterprise 11g and the front end is ChemAxon (basically, chemistry database software). The short of it is that I have one large table with every compound from different groups. Each row has a flag (column PI) on it that indicates which group it belongs to (let us say 'Smith' and 'Jones' for example). The software can apply row-level filtering which will basically only show the rows that a particular username are allowed to see.
I have a FLAG_TABLE table, which contains two columns: USERNAME and FLAG. An example set up is this:
USERNAME FLAG
------------- ----------
smith_minion Smith
jones_minion Jones
jones_minion Smith
The software automatically applies a SQL filter that begins with:
SELECT DISTINCT CHEMAXON.STRUCTURES."ID" FROM CHEMAXON.STRUCTURES WHERE
I can set up filtering to work dandy, such that when smith_minion logs in, he can only see rows with the Smith flag (or jones_minion can see both Jones and Smith) by using the filter:
STRUCTURES.PI IS NULL or STRUCTURES.PI IN(SELECT ALL FLAG from FLAG_TABLE where USERNAME = '__IJC_USERNAME__')
('__IJC_USERNAME__' is how the third party software passes the logged in username into SQL)
But we have a new problem: there also exists a master user (chemaxon) who needs to see every row no matter what the flag. The row filtering is applied no matter who logs on, so we need to set up the SQL filter to basically say "If chemaxon, then select all rows, otherwise, select rows based on the username". This is proving a problem as the select statement must be prefaced with SELECT DISTINCT CHEMAXON.STRUCTURES."ID" FROM CHEMAXON.STRUCTURES WHERE.
I've tried using DECODE in a few capacities, but I am always thwarted. My last attempt was:
STRUCTURES.PI IS NULL or STRUCTURES.PI IN (DECODE('__IJC_USERNAME__','chemaxon',(!='something'),(SELECT ALL FLAG from FLAG_TABLE where USERNAME = __IJC_USERNAME__));
But this throws a ORA-00936 missing expression error, with a * under the != portion (I test it by replacing '__IJC_USERNAME__' with 'CHEMAXON').
Is it possible to have $ substitutions in Select statements ?
For example
Select * from my_table where ID in ${ID_LIST} and DAY >= to_date(${SOME_DATE})
$ID_LIST = (100,200,300)
$SOME_DATE = 10-10-2011 12:12:00
For the ID_LIST is using Prepared statements with ?,?,? the way to go ? Or are there are any Define we can do in SQL plus for this substitions ?

View 3 Replies View RelatedDDL statements automatically end with COMMIT the user transactions in which they appear. Foe example:
-------------------------------------------
create table mytable01 (i integer);
insert into mytable01
select 1 from dual;
create table mytable02 (i integer);
-------------------------------------------
After all three statements are executed, data are committed in mytable01.
In the Oracle DB server SQL guide we read:
"DDL commands, such as TRUNCATE, will fail if there is any DML command active on the table. A transaction will block the DDL command until the DML command is terminated with a COMMIT or a ROLLBACK."
But I executed the following without any problem:
-------------------------------------------
create table mytable (i integer);
insert into mytable
select 1 from dual;
commit;
update mytable
set i = 2;
alter table mytable add (j integer);
-------------------------------------------
So where's the truth? Are DDL statements blocked when they refer to an active object accessed from a DML or not?

View 8 Replies View RelatedI have been out of work for 2+ years. Am about to start a job next week doing Oracle back end, Forms, and Reports development among other things. I was asked if I could take a look at 3 report requirements and give an estimate on how long it would take to correct errors in these reports. All I have is a user requirement document stating what the report is currently doing and what it should be doing, a partial screen print of an Oracle Form showing correct data, and a sample report page showing incorrect data.
I am finding it rather difficult to give an estimate without seeing tables, relations, code, etc. Is it me or does this seem nearly impossible?I do not have access to their system yet so cannot view the database or run select statements, run the report, etc. All I have are the documents I listed above.

View 2 Replies View Relatedconnect the following concepts/information I've been collecting. This is not my field but I'm interested in filling some of mine conceptual/technical gaps.
From a JDBC perspective, one of the benefits of Prepared (and so Callable) statements have over the regular ones is that the statement is "compiled"(*) once and then reused (performance gain).
(*) for SQL statements: building of parse tree and exec.plan
In which way can this notion be extrapolated to invocation of Oracle Stored Procedures through CallableStatements? (After clearing my doubts, I may end concluding that the only relevant feature of CallableStatements is their capacity to deal with stored procedure invocations)
According to procedure's precompiled execution plan SQL compilation implies execution plans generation PL/SQL compilation implies P-code generation and, SQL statements (from PLSQL code) are treated no differently by Oracle than SQL from Java or C/C++. These SQLs will be parsed and execution plans for those SQLs created.
...
When the PL code executes the SQL statement, only then does the SQL engine receive the SQL, parse it, and create an execution plan for it.
Therefore, even when the stored procedure can be parsed and cached in SGA (through the OracleConnection.preparedCall("proc") invocation), the SQL statements won't be effectively compiled until they are executed, right? And going deeper, will those SQL statements be cached to be reused in future invocations of the containing stored procedure? Is this a characteristic of the regular stored procedure execution in Oracle? or is it due to the CallableStatement "origin"?
It started out pretty simple where I had to update about 40 contacts in the database and I would have 40 separate update statements I would run. The task has jumped to about 300 contacts and I don't want to run 300 update statements. I would like to run this all at once. For example:
update contact
set name = 'Name1'
where row_id = 'row_id1'
update contact
set name = 'Name2'
where row_id = 'row_id2'
update contact
set name = 'Name3'
where row_id = 'row_id3'
