SQL & PL/SQL :: IF / THEN Statements With Different Datatypes
Sep 30, 2011
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"

On DB 11.2. I am dynamically building a DB after update trigger that compares old/new column values. I wanted to include a nvl statement in my if conditions as some field values may be blank.
Since I have many different datatypes (varchar,date,number,blob,clob), is there a single nvl comparison I can use that will work against all of these? I was hoping not to have to check the datatype and change my nvl comparison depending on what type it is. i.e.
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 ?

I am working on a data migration project where I am extracting data from Oracle8i database and writing it to a Text file using File_UTL utility. In one extract procedure, I need to write a LONG datatype with some VARCHAR2 datatype in extract file. Procedure compiled fine but I am getting the "ORA-00932: inconsistent datatypes" error while executing the final procedure to write data to a file.
below the code snipplet. I am trying t write Account_Primarykey, Account_name and it's AText (LONG datatype) together in a extract file:
create or replace procedure FORCE_W_ACCOUNT as Begin declare file_handel UTL_FILE.FILE_TYPE;
Have table with two columns with datatypes as number and varchar and the values in A column like 1,2,3 AND B column values like a,b,c. Now need to display data in a single column as 1,a,2,b,3,c.
I am fetching more than one column data from a table repetedly(By different query string each time) through ref cursor using concatenate function successfully. But I can see if one concatenate function is getting missed due to human intervention, it's causing failure for entaire process and returning oracle exception as "Failed - ORA-00932: inconsistent datatypes: expected - got -".
I'm new to XML to Oracle data integration. I do have clob column that has the XML data and trying to bring it into the Oracle relational tables, as a part of it we are developing PL/SQL procedure that calls this CLOB column, I want to know if we can variablize the data types ( Just like tablename. column name%type) in the select of the XML data:
I do define the data types after every column name , the problem is incase there is change in datatype I do need to manually edit the procedure to change the datatype is there a way I can variablize them something like tablename.columname%type.
My table looks like this -> Dp_value 124325 2434 3536 3536
Code is -> (case when CL.DECIMALPLACES = 0 and CL.FIELDTYPE = 'D' and cl.DATATYPE = 'N' then trim(dp."Value")*1000 else dp."Value" end) as dp_value,
What I am trying to do -> From another table cl I want to say if decimal place is 0, fieldtype is decimal (D/C) and datatype is number (N/T)then multiply the number with 1000.
If not then leave it as it is.
When I run my code I get the error: ORA-00932 : inconsistent datatypes: expected NUMBER got CHAR for else dp."Value" end)
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.
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 .
find out these details?.Which Data Dictionary i need to use ?.
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').
My teacher taught the lesson of DML statemnts, he told us how does merge works , but he did not give us any query for that,provide query for Merge and if possible then explain it too , I am using Oracle 10g Sql Plus.
DDL 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?
I 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.
Recently we have upgraded from 11.1 to 11.2 . But after upgrade SQL statements that are running fine in 11.1 was running for hours in 11.2. Statistics are collected 100%...
