I have used a decode statement in my query instead of using select * from <table_name> where value in <>
Instead I have used decode(value,<value1>, <value2>)
Which would be a better performance code?
Here is one an example with CASE WHEN statement.
SELECT empno,ename,sal,
CASE
WHEN sal BETWEEN 800 AND 1200
THEN 'Lowest Pay'
[Code]...
even DECODE can be a replacement for this scenario, but it cannot have as flexibility as CASE can have.
Now, I want Equivalent code for DECODE..
I'm having some trouble writing this query using a decode statement within a join. First, lets say I have two tables. Table A has the fields 'Baseline', 'NAD', 'Null', and 'Harn'. Table B has the fields 'Null', 'NAD', and 'Harn'. I want to join these tables together by these fields to return their ID's. Because table B doesn't have 'Baseline' to even have a match between the two tables, in Table A, we want to treat 'Baseline' as 'Harn', hence a decode statement. My query is below
Select
...
...
...
From
...
inner join oracle_srid_xref B on A.horizontal_datum = B.horizontal_datum and
decode(A.horizontal_epoch, 'BASELINE', 'HARN', loc.horizontal_epoch ) = B.horizontal_epoch
I'm not getting the ID's where the horizontal_epoch was initially 'Baseline'
Can we call a function within decode statement. I am able to do the same for simple example function . But In my actual procedure it's giving the error message . Are there any restrictions to call function with in decode statement?

I have to conditionally update a set of columns in a table. If the column status_code_stage_3 IS NULL THEN I have to update the column status_code_stage_2. The below query is giving error:-

I am trying to use decode function in sql and inside decode function can I use select statement ?
here is my sql
select we.wf_entity_id, decode(object_type_id,
1, select audit_number from ea_audit_general where sys_audit_id=object_id
2,'test',
object_type_id
) from wf_entity we
where
[code]....
see this
decode(object_type_id,
1, select audit_number from ea_audit_general where sys_audit_id=object_id
2,'test',
object_type_id
)
will this work? Its not working for me?
I was trying to write nested decode statement with multiple searches. For example
Case when seq = 1 and date1 > date2 then Record_Name End
How can i modify this to decode.

small piece of PL SQL code. how to make this query.Requirement is that a concurrent program is run with parameters and one of them i_num_org_id is non mandatory so it can come as NULL...Now in an existing code which i have to change, it uses a query as
SELECT xyz
FROM abc_table
WHERE <various conditions>
AND DECODE(i_num_org_id,NULL,1,table.organization_id) = NVL(i_num_org_id,1);
Now with the above way, if the program is run with some value for i_num_org_id or run as normal query (with NULL as the value) inside a PLSQL procedure/package then it runs fine.This query if you run in Toad etc then too it will work fine but if it is made a dynamic SQL and then used as either EXECUTE IMMEDIATE or opened as a cursor then we get a "Missing expression". I created this small anonymous block to test this and this will go into missing expression error
declare
l_num_org_id NUMBER := NULL;
l_temp VARCHAR2(100);
l_sql varchar2(1000);
begin
l_sql := 'SELECT '||''''||'abcd'||''''||'
[code].....
how i can reformat this query so that even if NULL value comes for i_num_org_id then it is handled.I am aware about CASE but that cannot be used in WHERE clause i guess.

We've got a query which returns one row, but uses an IN statement. The IN statement links to more than one row in the subquery. When we use a combination of DISTINCT and an ANALYTICAL sum, the sum total is multiplied by the number of rows in the sub query. Remove the DISTINCT and we get a single value.
A simplified example of the problem is below.
I can't see how a query which returns a single row then returns multiple values with the addition of a DISTINCT. Removing the analytical sum also provides a single row, but we need this in the actual query we're running. So it seems to be some combination of DISTINCT, ANALYTICAL SUM and IN query is causing multiple values to be returned.

I've seen this example numerous places, and tried to implement it, but I keep getting an "invalid identifier" error message, despite the fact that I've got the table and column specifically identified.For instance, my query reads like:
UPDATE tbl1
SET tbl1.EMPID =
(SELECT tbl2.EMPIDA FROM tbl2
WHERE LOWER(tbl1.EMAILCOL) = LOWER(tbl2.EMAILCOL2)
)
WHERE tbl2.EMPIDA IN ('Z1O435','S8M4722','M0D5156')
AND EXISTS
(SELECT tbl2.EMPIDA
FROM tbl2
WHERE tbl1.EMAILCOL= tbl2.EMAILCOL2 );
But I'll keep getting flagged at the tbl2.EMPIDA column reference. I have not tried this in SQL Plus, just in TOAD, but it seems to repeatedly fail.I have had to dump records to standalone Access tables and link back to perform the updates.
I am running one update statement which is running almost one hour still no response.
I would like to know either query is processing or hanging(suppose to finish the update within few minutes).
Is there any way or sql to find either the statement(my update query) is running or hanging.

I want to convert the below SQL to a dynamic sql to be executed from execute immediate statement.
UPDATE transaction SET loannum = lpad(loannum,12,'0')
I would like to store my sql query output into text file.Like for example:
select name from emp where emp_id=101;
Here output should be in text file as
swapna.
I dont want to use spool statement here,since If I use it,spool statement will also be printed in text file which is not my requirement.I just want to take only output.
