Subquery in Select Statement

Hi,
In crystal reports 10 is there a way to alter the select statement to include a subquery into the select statement. For example
select customer.lastname from customer;
to be
select customer.lastname , (select departmentname from dept where customer.dept_id= dept.dept_id) as "Customer_DeptName"
from customer;
I don't know how to do this in crystal but this can easily be done in toad or other sql query tool.
Please advise.
Thanks.
Tom.

hi Tom,
i walk through how to create a sub select (using a command object instead of using tables) in this post here...

USING SUBQUERY IN SELECT STATEMENT

I am looking at reusing the results of a first query in a second select statement.
I have a first table "ACTIVE_FIELDS" in which I maintain the columns I want to query.
Table name ACTIVE_FIELDS
Field - Status
CODE - ACTIVE
DESCRIPTION - ACTIVE
NAME - INACTIVE
So I get the list of active fields by doing :
SELECT FIELD FROM ACTIVE_FIELDS WHERE STATUS=ACTIVE
It gives me : Code and Description.
I have then a second table MATERIAL with 3 columns CODE, DESCRIPTION and NAME.
I am looking at doing a query against MATERIAL table as follows
SELECT (SELECT FIELD FROM ACTIVE_FIELDS WHERE STATUS=ACTIVE) from MATERIAL and I expect to only get columns CODE and DESCRIPTION in the result.
If I want to add the NAME field in the result of my query, I just have to change status of NAME field in the eh ACTIVE_FIELDS table..
Can anybody help me with the exact syntax, I must miss a function to convert the result of the first query..

that data model looks suspiciously like an attribute-value generic model, thus the need for that funky sql.

Re: SIMPLE Database Design Problem !

How to model in OWB if you have a subquery in your select statement? (11.2)

Which operator (is it the Table operator) to use if I have a subquery as part of my select statement? (The way I do it works, but is not elegant. What I do is create a table for the subquery and than join that with the other sources to point to my target.) But, would appreciate the best way with OWB's features.
Here is the entire SQL (including the subquery):
SELECT to_numbe (null), course_id
at.book, lp.NAME,
(select b.pricing from qp_pricing_attributes b
where b.list_id = ll.list_id and b.product = at.product) sign,
ll.operand AS price, lhb.comments
FROM
pricing_attribs at,
list_lines ll,
list_h lp,
list_b lhb
WHERE 1 = 1
and ll.list_line_id = atrib.list_line_id
AND ll.list_header_id = lp.list_header_id
AND lp.list_header_id = lhb.list_header_id
Thanks you.

Hi
Doesn't need to be a table in the target. Let's take a very simple example, let's say you wanted to do the following;
select ename,(select dname from dept d where d.deptno=e.deptno) from emp e
Then DEPT is your lookup table and EMP is your driving table.
1. Add EMP on to the canvas.
2. Add in lookup operator
3. Bind lookup to DEPT
4. Hit finish
5. Map EMP.DEPT to DEPT.INGRP1 (the lookup operator)
6. Edit lookup operator, on Lookup Conditions tab set DEPTNO for lookup column, and DEPTNO for input attribute
7. Lookup complete now
You can add in a target table operator and map from the source EMP table and the output attributes of the lookup operator. you can change step 4 to carry on through wizard and define lookup, but I have chosen to do 5, to automatically get the names and datatypes of the inputs. There are lot of other options now in 11gR2 in the lookup.
Hope this makes sense.

Sql Error in Select statement when doing subquery

Hi,
I am trying to see what the error is in the subquery part of the select statement.
Subquery should be fetching the safety_stock_quantity based on the MAX(effectivity_date).
Any suggestions?

Pravn

Hi, Pravn,
Remember the ABC's of GROUP BY:
When you use a GROUP BY clause and/or an aggregate fucntion, then every item in the SELECT clause must be:
(A) an Aggregate function,
(B) one of the "group By" expressions,
(C) a Constant, or
(D) something that Depends entirely on the above. (For example, if you "GROUP BY TRUNC(dt)", you can "SELECT TO_CHAR (TRUNC(dt), 'Mon-DD')").
There's a GROUP BY clause in your main query, so every item in the main SELECT clause must be one of the above. The last item, the unnamed scalar sub-query, is none of the above.
How can you fix this problem? That depends on your data, the results you want, and perhaps on your Oracle version. If you'd like help, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved. Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
Always say which version of Oracle you're using.
You may have noticed that this site normally doesn't display multiple spaces in a row.
Whenever you post formatted text (including, but limited to, actual code) on this site, type these 6 characters:
\(small letters only, inside curly brackets) before and after each section of formatted text, to preserve spacing.

No database version specified?
No table structures/indexes given?
No indication of the cardinality, selectivity, skew of the data being queried.
Have you got a function based index for "trunc(course_start_date)"?
Why are you not specifying your comparison date as a DATE datatype rather than relying on implicit conversion? i.e. it should be "to_date('01-Jun-2007','DD-MON-YYYY')"
Have statistics been gathered on the data

barcode=r2.cardn and attend_date=r2.pdate group by enpno,pdate,cardn);
Pls tell me how to use with example
Thanks & regards

Subquery in SELECT list vs join

If I'm not mistaken, both queries below are functionally the same. Both return all rows from table1 and only show a value for table2.F7 if the first 4 characters of F7 equal F2.
My thoughts are this... It's nice that a subquery can be used in a select list, but it looks like, with all the sql I've written which uses that approach, I could have just as well used the join approach. Is this always true? Can someone show me as example where using a subquery in the select list is hands-down the better approach?
SELECT table1.F2,
(SELECT table2.F7 FROM table2 WHERE substr(table2.F7,1,4) = table1.F2)
FROM table1
SELECT table1.F2, table2.F7
FROM table1, table2
WHERE table1.F2 = substr(table2.F7,1,4)(+)
Let me add that, in my top example, multiple rows will never be returned by the subquery. If that were the case, then the join approach would be the only option.

Probably there is no general answer and you'll always have to check separately.
In the following example the scalar subquery turns out to be slightly more efficient than an outer join (15 gets versus 13 gets and compare the elapsed time):

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.

SELECT statement comparing 2 fields in a table.

Hi,
Can someone help me out in making a efficient SELECT statement for the follwing requirement.
Say, I want to select all the records from a database table where the field, PLANT is equal to field SALESORG in the table (i.e., when both fields are equal select that record).
Thanks & regards,
Sree

Hello,
I think this is the answer to your question... if you explain a bit more we can formulate a query.
Subquery
Variants:
1. ( select )
2. ALL ( select )
3. ANY ( select )
4. SOME ( select )
Effect
A subquery is a SELECT statement select that occurs within a
SELECT,
OPEN CURSOR,
UPDATE, or
DELETE statement
in the WHERE clause or HAVING clause, to check whether data from database tables or views meets certain criteria.
Subqueries have a restricted syntax in comparison to the normal SELECT statement:
SELECT result FROM source [WHERE where] [GROUP BY fields] [HAVING having].
Variant 1
( select )
If the subquery returns a single value, you can use any relational operator except LIKE and BETWEEN.
Example
Selecting the flights with the most passengers:
DATA: WA TYPE SFLIGHT.
SELECT * FROM SFLIGHT
 INTO WA
 WHERE SEATSOCC = ( SELECT MAX( SEATSOCC ) FROM SFLIGHT ).
WRITE: / WA-CARRID, WA-CONNID, WA-FLDATE.
ENDSELECT.
Note
If you use a subquery with a relational operator instead of EXISTS, you may only specify one column in the SELECT clause. This can be either a field from the database table or an aggregate expression. Subqueries of this kind are referred to as scalar subqueries.
Variant 2
ALL ( select )
If the subquery returns several lines, each containing one value, you specify that the comparison should apply for all of the values it returns.
Example
This example shows how to use ALL. It displays a list of the customer IDs of the customer (or customers) who have made the most bookings:
DATA: ID TYPE SBOOK-CUSTOMID, CNT TYPE I.
SELECT CUSTOMID COUNT( * ) AS C FROM SBOOK
 INTO (ID, CNT)
 GROUP BY CUSTOMID
 HAVING COUNT( * ) >=
 ALL ( SELECT COUNT( * ) FROM SBOOK GROUP BY CUSTOMID ).
WRITE: / ID, CNT.
ENDSELECT.
Variant 3
ANY ( select )
Variant 4
SOME ( select )
If the subquery returns several lines each containing one value, this variant specifies that the comparison should apply to at least one of the values returned. The IN operator is the same as the combination = ANY.
&ABAP_HINT
If you use a subquery with the EXISTS operator, the expression is true if the subquery selects at least one line. You can useuse * in the SELECT clause of subqueries that use EXISTS.
Example
Selecting all flights from Frankfurt to New York between 1.1.1999 and 31.3.1999 that are not yet full:
DATA: WA_SFLIGHT TYPE SFLIGHT.
SELECT * FROM SFLIGHT AS F INTO WA_SFLIGHT
 WHERE SEATSOCC < F~SEATSMAX
 AND EXISTS ( SELECT * FROM SPFLI
 WHERE CARRID = F~CARRID
 AND CONNID = F~CONNID
 AND CITYFROM = 'FRANKFURT'
 AND CITYTO = 'NEW YORK' )
 AND FLDATE BETWEEN '19990101' AND '19990331'.
WRITE: / WA_SFLIGHT-CARRID, WA_SFLIGHT-CONNID,
 WA_SFLIGHT-FLDATE.
ENDSELECT.
Subqueries such as the one in this example, in which the WHERE clause uses fields from the main query, are known as correlated subqueries. Subqueries can be nested, and a given subquery may contain any fields from other, hierarchically-superior subqueries.
In a correlated subquery, the subquery is executed for each line r returned by the main query. In the above example, the main query finds all flights in table SFLIGHT that are not full and that have a date that meets the selection criterion. The statement then performs the subquery for each of the records returned by the main query, using the corresponding values of CARRID and CONNID, to check whether the relevant flight operates between Frankfurt and New York.

ascii_update();
There are a couple of issues with it though, this bit doesn't work when no results are returned:
else {
 document.write("No results found");
And I want to limit the number of rows to 50.
Someone mentioned that "ROWCOUNT" could be the answer to both problems but I have no idea where it should go or how to write it into this code. I've tried Googling for an answer without much luck as I don't know a great deal about this coding.
Can anyone help?

Try adding

It will limit the number of rows to 50.If you limit by rownum and order in the same query you are ordering 50 random rows of the query.
you should order in a subquery before using rownum to get only the top results.

Can call a function in the select statement?

Is there any ways to call a function in the select statement?
what I like to do is this:
select deptno, totalEmployees(deptno), TotalSalary(deptno)
from emp;
I know it can be done by count(*) and join tables, but my case
is much more complex and the where clauses are different from
one function to another, and have many tables to join and many
combinations
Thanks

Functions can be used in a select statement subject to certain
restrictions, see
http://otn.oracle.com/docs/products/oracle8i/doc_library/817_doc/
server.817/a85397/statem9b.htm#2062024
It's under "CREATE FUNCTION> Keywords and Parameters> function>
Restrictions on User-Defined Functions"
Here is an except...
When a function is called from within a query or DML statement,
the function cannot:
a) Have OUT or IN OUT parameters
b) Commit or roll back the current transaction, create or roll
back to a savepoint, or alter the session or the system. DDL
statements implicitly commit the current transaction, so a user-
defined function cannot execute any DDL statements.
c) Write to the database, if the function is being called from a
SELECT statement. However, a function called from a subquery in
a DML statement can write to the database.
d) Write to the same table that is being modified by the
statement from which the function is called, if the function is
called from a DML statement.
Except for the restriction on OUT and IN OUT parameters, Oracle
enforces these restrictions not only for the function called
directly from the SQL statement, but also for any functions that
function calls, and on any functions called from the SQL
statements executed by that function or any function it calls.

Re: Select statement fails under Express, but works underForte when usi

Hi there,
I have logged this with Forte and it as been recognized as a bug ( #46554 ).
The Express methods you need to look at if you want to modify this behavior
are :
1 - BusinessQuery.BuildQuery() starting at line 217
2 - SqlQuery.GetWhereText() starting at line 60
We have gotten around the problem by modifying what Express generates by
changing it from ( col1, col2 ) in ( select col1, col2 ... ) to ( col1 +
col2 ) in ( select col1 + col2 ... )
Just one thing i'm not sure that the '+' is standard on every DBMS for
concatenation.
We are using SQL Server 6.5
Hope this helps.

Subject: Select statement fails under Express, but works under Forte when
using DB2
Express sometimes (e.g. with nested windows) generates SQL with a select
subquery, e.g.
select x1, x2 from t1 where (x1,x2) in (select x1,x2 from t2.....)
This fails on DB2 with a message that the comma in the where clause (x1,x2)
is not allowed.
This works on Oracle.
Does anyone have a workaround or other suggestion?

There are rules for bind variables and that statement certainly looks suspicious.
If you can't get that to work then the rest of the attempt is pointless.

Roger,
This was a bug with Express and was fixed in Express E.2.0.L.0.
You might be able to get more details on Forte's website.

If statement in select statement alias

I have the following select statement. It has the alias Survivors, Deaths and "All Cases". Is it posible to use :P_LANGUAGE variable to say that -- IF :P_LANGUAGE = FRENCH THEN alias are Survivants for survivors, Décès for Deaths, Tous_les_cas for All Cases. Please advise
SELECT ALL T_NTR_MULTIBAR.CAT, T_NTR_MULTIBAR.NUM_CASES_LEFTBAR AS Survivors,
T_NTR_MULTIBAR.NUM_CASES_MIDDLEBAR AS Deaths, T_NTR_MULTIBAR.NUM_CASES_RIGHTBAR AS "All Cases"
FROM T_NTR_MULTIBAR
WHERE INSTANCE_NUM = :P_INSTANCENUM
order by ORDERS

You may not be able to add this condition inside the SQL Statement. But you can add this condition outside the statement, if you're using PL/SQL...
IF :p_language = french THEN
SELECT ALL t_ntr_multibar.cat,
t_ntr_multibar.num_cases_leftbar AS survivors,
t_ntr_multibar.num_cases_middlebar AS deaths,
t_ntr_multibar.num_cases_rightbar AS "All Cases"
ELSE
END IF;
