Missing right parenthesis while executing this query - oracle

Select a.*,
when to_number(prem_term='annually')then to_number(prem_amt×1)
when to_number(prem_term='quaterly') then
to_number(prem_amt×4)
when to_number(prem_term='semi annually') then
to_number(prem_amt×2)Else end
From policy_holder a;

Missing CASE and value you'd want to return in case of ELSE, superfluous & invalid TO_NUMBER function calls. Maybe you wanted something like this:
SELECT a.*,
CASE
WHEN prem_term = 'annually' THEN prem_amt * 1
WHEN prem_term = 'quaterly' THEN prem_amt * 4
WHEN prem_term = 'semi annually' THEN prem_amt * 2
ELSE NULL
END
FROM policy_holder a;

Missing Keyword when using Case in Where clause

I am using case in where clause but getting error: missing keyword
SQL:
SELECT *
FROM tmp t
WHERE
CASE :p_flag WHEN 'Y'
THEN t.call_destination NOT IN ('Premium', 'Satellite')
ELSE t.call_destination LIKE call_destination
END;
The predicate of a CASE expression has to be a single value, not another expression. If I read your WHERE clause correctly, you ought to be able to rephrase your query as follows:
SELECT *
FROM tmp t
WHERE
(:p_flag = 'Y' AND t.call_destination NOT IN ('Premium','Satellite')) OR
(:p_flag <> 'Y' AND t.call_destination LIKE call_destination);
-- ^^^ not sure about this
I have highlighted a LIKE comparison you are making which does not seem to make sense because it would always return true.

Using IF statements in Oracle when trying to return data

How do I return data out of IF statements? I have a IF statement which is meant to return a different result dependent of the result of that statement.
IF :Value = 1 THEN
SELECT Name FROM TABLE_A
ELSEIF :Value = 2 THEN
SELECT Name FROM TABLE_B
ELSEIF :Value = 3 THEN
SELECT Name FROM TABLE_C
but this doesn't work. It expects an INTO statement in those selects. I suspect this is because Oracle can't return out of a block?
Is there a quicker way to return those select statements without creating table variables to store the data or messing around with functions?
You can do this by plain SQL:
SELECT
':Value' user_input,
CASE
WHEN ':Value' IN('a1','a2','a3')
THEN (select name from table_a)
WHEN ':Value' = 'i'
THEN (select name from table_b)
END AS output
FROM
dual
(good info about case)
If you want more than one result in your cases, then you may opt to an intelligent UNION:
SELECT t1_Col_1, t1_Col_2,'&VALUE' from TABLE_1
WHERE '&VALUE' = '1'
UNION ALL
SELECT t2_Col_1, t2_Col_2,'&VALUE' from TABLE_2
WHERE '&VALUE' = '2'
In this solution, types and number of tx_Coln must be the same.

I'm getting erros at the line

saying "missing keyword". Is it possible to use the merge statement in a SP? I'm new to Oracle so I really don't know if what I'm trying to do is possible or if there's something wrong with my code.
Thanks for any help, I would really appreaciate it.
I think that you swapped commands - after when matched you should put update statement and after not matched - insert.
Similar example worked for me, but after swapping statements I got ORA-00905 missing keyword. So correct version is:
merge into t1
using (select * from t2) t2 on (t1.id = t2.id)
when matched then update set t1.name = t2.name
when not matched then insert (id, name) values (t2.id, t2.name)

PL/SQL : Example for select and update the record based on certain rule

I have situation something like below...
select * from tableA A
if A.salary > 100 and A.years > 0 then
update tableA set A.level = '1' where A.id = id;
else if A.salary > 200 A.years > 1 then
update tableA set A.level = '2' where A.id = id;
else
update tableA set A.level = '0' where A.id = id;
end if
how i can implement this in PL/SQL? above situation is just an example.
You don't need to do this in PL/SQL; it can be done in a single UPDATE statement by using a CASE expression:
update tablea
set level = case when salary > 100 and years > 0 then 1
when salary > 200 and years > 1 then 2
else 0
end
It's worth noting that "level" is a reserved word (it's a psuedocolumn used for Oracle's hierarchical queries) and can cause problems if you use it. I'd choose something else if possible.

Need a fix for merge update query (Simple but still confusing)

MERGE INTO table_1 a
USING
(SELECT * from table_2) b ON ( a.row_id = b.row_id and a.in_correct IS NULL)
WHEN MATCHED THEN UPDATE SET a.in_correct = 'Y';
In the above query ORA-38104:Column referenced in ON clause cannot be updated.
I have been sitting for hours to resolve this.
I have identified that the problem is the field in_correct.
This field "in_correct" cannot be put in both ON clause and also after SET. But in order satisfy my criteria,I have no option.
Please help me out
MERGE INTO table_1 a USING
(SELECT * from table_2) b
ON ( a.row_id = b.row_id)
WHEN MATCHED THEN UPDATE
SET a.in_correct = NVL(in_correct, 'Y');
UPDATE:
A more "general" command (for non null values):
MERGE INTO table_1 a USING
(SELECT * from table_2) b
ON ( a.row_id = b.row_id)
WHEN MATCHED THEN UPDATE
SET a.in_correct = case
when in_correct = 'valuetobereplaced' then 'Y';
else in_correct;
end;
