Decode in the select Statement

Hi All,
I am using the decode function in the select statement....but as i am using the group by in the select statement....i am not able to run the same query
How to tackle this problem of handling the decode ....while we have group by also.
This is bit urgent
Thanks for your help

Count(*) in select statement having group by clause

Hi
I would like to use count(*) in select statement having group by clause. say for example there is a state with a number of cities listed. I would like to get the count of cities for each state.
the sql stement is grouped by city and it is joined with 5 more tables.
Thanks

I suspect you want to look into analytic functions (assuming you have a recent version of Oracle). asktom.oracle.com has numerous examples if you do a search.

Count(*) function in select statement having group by condition

Hi
I would like to use count(*) in select statement having group by clause. say for example there is a state with a number of cities listed. I would like to get the count of cities for each state.
the sql stement is grouped by state and it is joined with 5 more tables.
Thanks
ps: ignore the previous post

Assuming there is one record per city per state, then
SELECT state,count(*)
FROM state_tbl
GROUP BY stateWill get one record per state with the number of cities in each state. If you want to join that result set to other tables you need to either create a view with that statement or use an in-line view viz.
SELECT c.cust_name,c.state,s.num_cities
FROM customers c,
     (SELECT state,count(*) num_cities
      FROM state_tbl
      GROUP BY state) s
WHERE c.state = s.stateTTFN

Group By Select Statement aggregate function error.

I am using Dreamweaver MX4 and have an ASP web page. I can easily do this in Access 2007 a simple "group by" sum totals statement.
Why can I not get this to work on a web page? Are the "#" signs messing this up in the Code2 Select Statement?
How can I get Code2 to work correctly? Code1 works fine. A user enters the customer and a date range on a form and submits request. I get error message in Dreamweaver. You tried to execute a query where the specified expression field3 is not part of an aggregate function
Code1. This works fine SELECT Field3, Field10, SUM(Field16) as SumofField16 FROM CustomerHistory_CP WHERE Field3 LIKE '%Search_Criteria%' AND Field6 >= #1/2/09# AND Field6 <= #1/30/09# GROUP BY Field3, Field10

Hi,
Assign the alias in a sub-query. Then you'll be able to use it wherever you want to, and how many times you want to, in a super-query.
For example:
WITH     got_vendor     AS
     SELECT     hdr.business_unit
              SELECT v.name1
              FROM    ps_vendor     v
              WHERE   strm.vendor_id     = v.vendor_id
              AND     v.setid          = (
                                            SELECT setid
                                    FROM    ps_set_cntrl_rec
                                    WHERE   recname          = 'VENDOR'
                                    AND     setcntrlvalue      = strm.business_unit
          )           AS vendor_name
     FROM      ps_qs_sessn_hdr8     hdr
SELECT       business_unit          -- NOTE: no hdr.; all columns are from got_vendor now
,       vendor
FROM       got_vendor
GROUP BY business_unit
,       vendor
;When you define an alias (such as vendor) in a query, you can use that alias in the ORDER BY clause of that same query, but that's the only place in that same query where you can use it. If you want to use the alias anywhere else (e.g., in the GROUP BY clause, as in your example, the WHERE clause, or elsewhere in the SELECT clause), then you probably want to compute it in a sub-query, as shown above.
There's probably a better way to compute vendor, but that's a separate problem.

MySQL Select Statement Help Required

I am trying to generate a report in VS 2008 (C#) using a mysql select statement but cannot get it right.
I have groups that meet on a weekly basis on different days. I want to generate a report that shows me all the members that have not attended their group where they have missed 3 meetings in a row.
Below is the select statement I have tried but it does not give me the results I am looking for. I have tried to look at all the meetings in a 4 week period but would prefer to look at the last 3 meetings that are recorded. Some groups might not record a meeting every week. So I want to look at the last 3 recorded meetings and count each members attendance and only report on the members with more than 3 meetings missed.
SELECT COUNT(`groupattendance`.`Attended`) AS Attendance, `smallgroupform`.`MeetingDate`, `userinfo`.`FirstName`, `userinfo`.`Surname`, `smallgroup`.`GroupName`, `groupattendance`.`Attended`, `groupattendance`.`UserID`, `groupattendance`.`GroupID`
FROM ((`anatomy`.`groupattendance` `groupattendance`
INNER JOIN `anatomy`.`smallgroupform` `smallgroupform` ON `groupattendance`.`FormID` = `smallgroupform`.`FormID`)
INNER JOIN `anatomy`.`userinfo` `userinfo` ON `groupattendance`.`UserID` = `userinfo`.`UserID`)
INNER JOIN `anatomy`.`smallgroup` `smallgroup` ON `groupattendance`.`GroupID` = `smallgroup`.`GroupID`
WHERE (`smallgroupform`.`MeetingDate` >= DATE_SUB(CURDATE(),INTERVAL 4 WEEK) AND `smallgroupform`.`MeetingDate` <= CURDATE()) AND `groupattendance`.`Attended` = 'False'
GROUP BY `userinfo`.`UserID`
HAVING Attendance >= 3
Thanks,
Garth.

Hi Garth,
Seems no one can help you directly. Try googling your SQL request. Someone may be able to help you. At this point its not really a Cr problem.
One option is to get all the data and add filtering using the record selection formula.
Thank you
Don

What is the problem?

It's hard to say: what's your request timeout set to?
700-odd records is not much of a fetch for a decent DB, and I would not expect that to case the problem. But then you're using Access which doesn't fit the description of "decent DB" (or "fit for purpose" or "intended for purpose"), so I guess all bets are off one that one. If this query is slow when ONE request is asking for it, what is going to happen when it goes live and multiple requests are asking for it, along with all the other queries your site will want to run? Access is not designed for this. It will really struggle, and cause your site to run like a dog. One that died serveral weeks ago.
What else is on the template? I presume you're doing something with the query once you fetch it, so could it be that code that's running slowly? Have you taken any steps to isolate which part of the code is taking so long?
How does the query perform if you take the subquery out of the select line? Is there any other way of getting that data? What subquery will be running once for every row of the result set... not very nice.

What is the use of additon in up to 1 rows in SELECT statement

Hi All,
         What is the use of up to 1 rows in select statement.
for example
SELECT kostl
      FROM pa0001
      INTO y_lv_kostl UP TO 1 ROWS
      WHERE pernr EQ pernr
      AND endda GE sy-datum.
    ENDSELECT.
I'm unable to get in wat situations we hav to add up to 1 rows
please help me out...
Thanks,
santosh.

Hi,
Use "select up to 1 rows" only if you are sure that all the records returned will have the same value for the field(s) you are interested in. If not, you will be reading only the first record which matches the criteria, but may be the second or the third record has the value you are looking for.
The System test result showed that the variant Single * takes less time than Up to 1 rows as there is an additional level for COUNT STOP KEY for SELECT ENDSELECT UP TO 1 ROWS.
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.

Is there any way to Mask the Name when a select statement is issued?

Dear all,
Is there any way to mask the name .. i mean if User issue a select statement in a customer table the real name should come like ' ABCXXXDEFXXCFXX'... Which is not the actual name?
e.g if Name: CHIEV SONG MEE
If user issue a statment select * from customers;
The Result Should come something Like this:
Name
CHXXV SXNG MXX
Thank You

user3029023 wrote:
but it seems there is no option in oracle it self which can be used as there they are saying to get a data masking software which we can't due to some internal issues....I would not say that. How one implements masking depends entirely on the requirements that need to be met.
For example, schema A owns all the tables. Schema B can be created as a "trusted" schema - in other words, schema A trusts schema B and allows it full access (with grants) to its tables. Schema B implements data masking as views. For each table in A, a view exists in B that implements the required masking. B can now grant select access on these views to user C. User C will see the same data object names in B as it would have if it used A - only, by using the B data objects it uses masked data objects and not the original source data objects.
Another example - schema Dev is to have all the data objects of schema Prod, but masked where needed. One can use CTAS (Create Table As Select) to create the required tables in Dev with masked values where relevant. This Dev schema can be "refreshed" on weekends by dropping all tables and getting a new fresh copy of production data and masking it - ready for the next week's development cycle.
If the application use is for example APEX, then instead of coding SQL directly as reporting regions to display, a function is used instead. APEX supports reporting regions where it calls a function and this function provides the APEX run-time with the SQL to execute and contents to render. It is easy to use this approach to implement logic in functions that masked column data depending on who the APEX user is, the security/role attributes of the user, and so on.
No there is not a single "+mask this column!+" feature in Oracle.. but that does not mean that such a feature is not supported and cannot be implemented. Oracle has a very comprehensive and rich set of tools - more so than most (if not all) other RDBMS products.
It is up to the architect/designer/developer to use this toolkit in creating a system that meets the specific requirements at hand.

If I want to order by dateAdded to I have to include it in the select statement like

If I do this:
<cfquery name="chart" datasource="#datasource#">
select behaviourID,score, dateAdded2 = convert(varchar,
dateAdded , 101)
from staff_charts_data
where userID =
<cfqueryparam value="#arguments.userID#"
cfsqltype="cf_sql_integer"> AND
NOT score = 5
</cfquery>
If I want to order by dateAdded to I have to include it in
the select statement like so:
<cfquery name="chart" datasource="#datasource#">
select behaviourID,score, dateAdded2 = convert(varchar,
dateAdded , 101),dateAdded
from staff_charts_data
where userID =
<cfqueryparam value="#arguments.userID#"
cfsqltype="cf_sql_integer"> AND
NOT score = 5
</cfquery>

you should be able to order by dateAdded without it being in
the select clause. The only time the order by field has to be in
the select clause is when your query has an aggregate and group by
clause, like this:
select field1, field2, max(field3) as youralias
from sometables
where whatever
group by field1, field2
order by ???
You can only order field1, field2, max(field3) or youralias.
You can't order by field4.

Using Select statement in IF condition?

hi all,
Can i use select statement in IF COndition in pl sql ?
eg like- if( select 1 from ASD) then
end if;

There is no way to do any kind of select statement inside if conditions.
Why don't test simple cases like this first?
An example to show it.
SQL> begin
2   if exists (select 1 from dual) then
3    dbms_output.put_line('ok');
4   end if;
5 end;
6 /
if exists (select 1 from dual) then
ERRORE alla riga 2:
ORA-06550: line 2, column 5:
PLS-00204: function or pseudo-column 'EXISTS' may be used inside a SQL

Return multiple values from a function to a SELECT statement

I hope I've provided enough information here. If not, just let me know what I'm missing.
I am creating a view that will combine information from a few tables. Most of it is fairly straightforward, but there are a couple of columns in the view that I need to get by running a function within a package. Even this is fairly straightforward (I have a function named action_date in a package called rp, for instance, which I can use to return the date I need via SELECT rp.action_date(sequence_number).
Here's the issue: I actually need to return several bits of information from the same record (not just action_date, but also action_office, action_value, etc.) - a join of the tables won't work here as I'll explain below. I can, of course, run a separate function for each statement but that is obviously inefficient. Within the confines of the view select statement however, I'm not sure how to return each of the values I need.
For instance, right now, I have:
Table1:
sequence_number NUMBER(10),
name VARCHAR(30),
Table2:
Table1_seq NUMBER(10),
action_seq NUMBER(10),
action_date DATE,
action_office VARCHAR(3),
action_value VARCHAR(60),
I can't simply join Table1 and Table2 because I have to do some processing in order to determine which of the matching returned rows I actually need to select. So the package opens a cursor and processes each row until it finds the one that I need.
The following works but is inefficient since all of the calls to the package will return columns from the same record. I just don't know how to return all the values I need into the SELECT statement.
CREATE VIEW all_this_stuff AS
SELECT sequence_number, name,
rp.action_date(sequence_number) action_date,
rp.action_office(sequence_number) action_office,
rp.action_value(sequence_number) action_value
FROM table1
Is there a way to return multiple values into my SELECT statement or am I going about this all wrong?
Any suggestions?
Thanks so much!

Hi,
What you want is a Top-N Query , which you can do using the analytic ROW_NUMBER function in a sub-query, like this:
WITH     got_rnum     AS
     SELECT     action_seq, action_dt, action_office, action_type, action_value
     ,     ROW_NUMBER () OVER ( ORDER BY action_date
                               ,            action_seq
                         ,            action_serial
                       ) AS rnum
     FROM     table2
     WHERE     action_code     = 'AB'
     AND     action_office     LIKE 'E'     -- Is this right?
SELECT     action_seq, action_dt, action_office, action_type, action_value
FROM     got_rnum
WHERE     rnum     = 1
;As written, this will return (at most) one row.
I suspect you'll really want to get one row for each group , where a group is defined by some value in a table to which you're joining.
In that case, add a PARTITION BY clause to the ROW_NUMBER function.
If you'd post a little sample data (CREATE TABLE and INSERT statements), I could show you exactly how.
Since I don't have your tables, I'll show you using tables in the scott schema.
Here's a view that has data from the scott.dept table and also from scott.emp, but only for the most senior employee in each department (that is, the employee with the earliest hiredate). If there happens to be a tie for the earliest hiredate, then the contender with the lowest empno is chosen.
CREATE OR REPLACE VIEW     senior_emp
AS
WITH     got_rnum     AS
     SELECT     d.deptno
     ,     d.dname
     ,     e.empno
     ,     e.ename
     ,     e.hiredate
     ,     ROW_NUMBER () OVER ( PARTITION BY d.deptno
                               ORDER BY         e.hiredate
                         ,                e.empno
                       ) AS rnum
     FROM     scott.dept     d
     JOIN     scott.emp     e     ON     d.deptno     = e.deptno
SELECT     deptno
,     dname
,     empno
,     ename
,     hiredate
FROM     got_rnum
WHERE     rnum     = 1
SELECT     *
FROM     senior_emp
;Output:
.    DEPTNO DNAME               EMPNO ENAME      HIREDATE
        10 ACCOUNTING           7782 CLARK      09-JUN-81
        20 RESEARCH             7369 SMITH      17-DEC-80
        30 SALES                7499 ALLEN      20-FEB-81
By the way, one of the conditions in the query you posted was
action_office     LIKE 'E'which is equivalent to
action_office     = 'E'(LIKE is always equivalent to = if the string after LIKE doesn't contain any wildcards.)
Did you mean to say that, or did you mean something like this:
action_office     LIKE 'E%'instead?

Problem with Select Statements

Nice point there Siegfried. Instead of giving constructive suggestion, people here give a very bad suggestion on using SELECT SINGLE combined with SUM and GROUP BY.
I hope the person already look at your reply before he try using select single and wondering why he has error.
Anyway, the most important thing is how many loop expected for those select statements?
If you have like thousands of loop, you can expect a poor performance.
So, you should also look at how many times the select statement is called and not only performance for each select statement when you're doing SQL trace.

Abraham
