I have a complex expression coming as an input and I have to break that into smaller one to evaluate each of them. Explained in example:
Let's assume, I have an input string as "(({A}&{B})||({C}||{D})&({E}||({F}&{G})))". My requirement is to break into logical smaller groups like
1. ({F}&{G})
2. ({E}||({F}&{G}))
3. ({C}||{D})
4. (({A}&{B})

This group by query works. But how can i get the expression field (the first field which 'TEMPACCOUNT') in this query (based on my attached output).

New to using Oracle and SQL Developer. I am trying to subtract a maximum date from today and adding back 1 to get a field named daysSinceLastActivity....
Syntax I am trying is (date()-max(activity_date))+1 as daysSinceLastActivity
I keep getting a error message of missing expression. After googling, I am not finding anything. This should be a simple calculation.

I have a user interface where the user can enter a formula using a set of parameters and operators. For eg , the user is given a list of parameters, say : Width, Height , Gauge. The list of operators include standard math functions : + - / * ^
He can select and create a formula like gauge * width. This is stored in a table. At a later time a job is scheduled to evaluate the formula based on parameters for width, gauge and height.
I can evaluate the expression by substituting each parameter.
I can do this using dynamic sql. However I'm not sure how to evaluate the ^ symbol. The equivalent of this is power function.
So if a user enters (height * 2) + (width^2) . How do i evaluate this. I am doing this in pl/sql.

I am using pipelined functions. I've written a few with no problem this one seems to be giving an error when I am using techniques that appear very similar to ones that work.
I am doing this all in a package;
The type definition is;
TYPE SUSPECT_LINKAGES_FAC_RECORD IS RECORD
(
PATIENT_ID TUMOR.TUMOR_PATIENT_ID%TYPE,
CENTRAL_SEQ TUMOR.TUMOR_CENTRAL_SEQ%TYPE,
MP_REVIEW_FLAG NUMBER(1),
FACILITY_FLAG NUMBER
);
The variable definition is;
OUT_REC SUSPECT_LINKAGES_FAC_RECORD;
The line with the error is;
PIPE ROW(OUT_REC);
This is the entire function;
FUNCTION GET_SUSPECT_LINKAGE_FAC_FLAGS RETURN SUSPECT_LINKAGES_TABLE PIPELINED AS
CURSOR CURS_SUSPECT_LINKAGES IS
SELECT * FROM TABLE(TUMOR_UTILITIES.GET_SUSPECT_LINKAGE_FLAGS())
order by 1,2,3 DESC;
TEMP_REC SUSPECT_LINKAGES_RECORD;
MATCH_COUNT NUMBER;
OUT_REC SUSPECT_LINKAGES_FAC_RECORD;
[code].....
I get "PL-00382 expression is of wrong type" on both pipe row (out_rec); lines.

I have an arithmatic expression which is dynamic say
expression = [Col5]/[Col1]
I will be using this in building a dynamic SQL.so i have to make sure that the divisible by zero is taken care. In the expression Col1,Col5 are values coming from a SQL.
For the above expression, my conversion will be
ROUND( ((CCol4 / DECODE (CCol1, 0, NULL, CCol1) )), 0).
I have to build a function which takes in the expression and fetches me the result.My expression can be any combination of arithmaticexpression involving columns.
Ex:
[Col4 + Col2]/[Col3-Col1]*[Col5].

I ran into a problem recently which has to do with the following query:
SELECT '' || ROUND(GEOGR_LAENGE,5) || ',' || ROUND(GEOGR_BREITE,5) || '," [BUE] ' || BAUFORM_GRUPPE || '"', KM
AS TEXT
FROM MYTABLEA mmtable
WHERE (mmtable.GEOGR_LAENGE IS NOT NULL
AND mmtable.GEOGR_BREITE IS NOT NULL
AND mmtable.STRECKE_NR IN
(
[code].....
The problem is, that Oracle alerts a missing expression at line 4, and highlights the "IS NOT NULL". Personally I don't see that anything is wrong with this line. I think the problems source is somewhere else but I cannot find it.
I'll give you a little bit of background to the script:
What I am trying to achieve is to request the values in the first line with the following conditions:
- mmtable.GEOGR_LAENGE, GEOGR_BREITE must not be empty
- rbtable.STRECKE_NR for the requested line (which is similar to mmtable.STRECKE_NR) must have "MITTE" as a value for NL_NAME
- mmtable.KM => rbtable.VON_KM
- mmtable.KM <= rbtable.BIS_KM
so that only those lines will be returned.

I ran into something that has me wondering about which errors are caught at compile-time, and which are caught at runtime. There is a pretty big package with lots of complicated queries that heavily use GROUP BY, and in the last couple of years I thought I never had the case of an ORA-00979 happening an RUNTIME, which is now happening.
The last heavy changes in that package did I make in the Oracle 9.2 days, and I *believe* (although my memory might be wrong) that back then the ORA-00979 errors came up at compile time.
So is it normal that the error doesn't show up during compile time, only during runtime, or should it be considered a bug?

Can Group BY clause have an expression field?
Say for example, I want to group by the fields "Type" and and expression called "expression" (which is a case statement). I tried running this query and it says "expression" is invalide identifier.
select type, case when SUBSTR (glnumber, 1, 2) = '05' then 'IS'
when SUBSTR (glnumber, 1, 2) = '06' then 'IS'
else 'BS'
end "expression" , sum(balance)
from table
group by TYPE, "expression"
If there is any online material on how to GROUP BY on an expression(like above)

I'm trying to match all sentences that contain words starting with given search tokens at least once. For example: if the given search token words are one and two then only sentences like "one plus one is two" should match. And should not match sentences like "one plus three is four". I was able to come up with this but I need a AND condition which I'm unable to get it right.
select count(*) from dual where regexp_like('one plus one is two', '(^|s)one|three', 'i');
Currently this gives a count of 1. But needs to give a count of 0 when the regexp is fixed.
search words : one two
one is less than two -> match
two is greater than one -> match
onetwo is union of two numbers -> match
onetwo is union of 2 numbers -> not a match as 'two' is not at the beginning of a word
one is less than three -> not a match as two is not present.

i have been looking at a query that uses a wrong plan. db=11.2.0.3 with user bind peeking enabled. this is a simplified version demonstrating the problem:
select egp.bsn,egp.klantnummer as "Persoonsnummer", egp.samengesteldenaam as "Samengesteldenaam", egp.geboortedatum as "Geboortedatum"from pr_eigenschappen2 egpwhere(egp.bsn = :b1 or :b2 is null)and rownum < 51 egp.bsn is varchar2(10) and has high selectivity (almost unique), and is btree-indexed. table and index have adequate statistics. when run with b1:=928818 and b2:=928818 (both bound as varchar2(10)) a full table scan+filter is used on pr_eigenschappen2. if the query is changed to select egp.bsn,egp.klantnummer as "Persoons nummer", egp.samengesteldenaam as "Samengesteldenaam", egp.geboortedatum as "Geboortedatum"from pr_eigenschappen2 egpwhere(egp.bsn = :b1 or 928818 is null)
and rownum < 51the index on bsn is used, and the query is not taking 3.9 seconds but 1 millisecond.if i would have a choice, the query would be different. i don't want to talk about the raison d'etre of the query, i would like to know why the optimizer is not using the index in the first case.

A to Z
0 to 9
Special characters like - &,%,~,@,#,$,^,*,_,+,=,,/,<,>
Example
String - TEST@#_~````}{!!!12311HELLO
Expected result - TEST@#_~12311HELLO

I have a Identifier column with start and stop dates along with description .
Two dates are separated by '-'. But the position of that character(-) is not constant always. Depending on the instr function I am able to divide the start and stop dates. But I am getting the performance problem because of huge data
I think the same logic will be implemented by regular expression also . How to write the equivalent logic by using regular expressions
create table REG_EXP_TEST
(
TRANS_ID NUMBER(10),
TRANS_IDENTIFIER VARCHAR2(250)
) ;
insert into REG_EXP_TEST
(TRANS_ID, TRANS_IDENTIFIER)
