Select distinct statement with various alias

Hi everybody,
I'm trying to put a select distinct statement in a query with two different alias for two different tables; like that:
select distinct a.ma_name||'.'||a.ma_first_name d,
a.ma_first_name||'.'||a.ma_name r
from ma_main a, manager_liste b
where (UPPER(b.manager_first_name||'.'||b.manager_name) = :APP_USER or
(case when 'X'=:APP_USER or 'Y'=:APP_USER
then 1
else 0
end) = 1)
order by a.ma_name
But it doesn't work. Can anybody help?
Thx a lot!
Jan

hi,
this is the error:
1 error has occurred
LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query.
and the table manager_liste and ma_main are varchar tables.
how can i make it work, so that my select list with submit does only show distinct names. Because right now it shows each name about 10 times....

Problems with "Select Distinct" Statement

Hi... I've a little problem with my SQL Statement...
I've a Table in a DataBase with Solds of the Month... the fields are: vta_fecha, vta_prod, vta_total, vta_mesa.
I've to Select only the distincts fields of vta_prod... selected by vta_fecha and vta_mesa...
My code is like this:         try{

        }catch(Exception e){JOptionPane.showMessageDialog(null,e.getMessage());}Now, in the Table I have only 3 diferents vta_prod, but this Statement returns 9 Rows... and I don't know why...
Please help me...
Regards...

I don�t have a complete picture because I don�t know what values you are passing in the select and I don�t know your column types but this is what I think is happening from what you have shared.
You may have misunderstood what the DISTINCT keyword does.
The DISTINCT keyword applies to the full set of columns in the select (not just the first column). So in your case it would be equivalent to:
SELECT vta_prod, vta_fecha, vta_mesa
FROM Ventas
WHERE ...
GROUP BY by vta_prod, vta_fecha, vta_mesa
So, it doesn't matter that you only have 3 distinct vta_prod values if you have multiple values being returned in the other columns. The vta_mesa column can only a return a single value as �0�. That leaves the vta_fecha column which is probably a date/time column and is probably the column that is returning the three other distinct values (one date with three distinct times).
(3 vta_prod) x (3 vta_fecha) x (1 vta_mesa) or 3x3x1 = 9 rows
So find a way to strip the time from vta_fecha in your select statement and your SQL should return the results you expect. I�m not an Access expect but I think I remember you can use something like the �Convert� or �DatePart� functions to make that happen (check your documentation to be sure)..
A couple of asides;
1) You should use a PreparedStatement and rarely if ever use Statement.
2) You should start Java variable names with lower case.

Select distinct problem with muliple join tables, help needed

Hi,
I have two main tables. Each has its of sub joined tables.
guest_id_for_reservation connects two major tables. This has
to be that way
because my guest may change the room status from single to
double (and the
similar exceptional requests).
guests reservation
guest_id_for_reservation
countrytable hoteltable
delegationtable roomtype
I form a query. I want to select distinct those results. But
it does not
work.
If I do not include any table related to reservation table
and its sub
joined tables (disregarding guest_id_for_reservation), it
works.
Is there a specific syntax for select distinct of this type
or any
workaround.?
Thank you

Hi I'm still battling with this - have connected the AX to my Imac via ethernet and it shows up fine in Airport Utility. Status light is green and it says its set up to connect to my existing wireless network using wireless connection. Security in Network Preferences is the same for both: WPA2 Personal.
So I don't think there's a problem with the AX, and my current wireless network (BT Home Hub) is working fine.
And when I restore factory settings Airport Utility can see the AX before updating settings so the wireless side of AX must work too.
I'm figuring it must be something about the settings that mean AU can't see it anymore. But I can't work out what, since security is the same.
Any ideas would be great!

Select SQL statement with variable syntax error

Hi All,
I am running a Web Application with a java bean to connect to a mysql database. i have compiled a test .java file whcih works using the same statement that has a problem in my web application. Taking the statement out of the Web App makes it work so it must be this stetment:
String SQLStatement = "SELECT * FROM MASTER WHERE USERNAME LIKE '"+data+"' ";
This works fine in testing a separate java file, but it does not compile when running ant build to compile the same line of code for my Web App.
I have tried many possibilities of changing the syntax to no avail, its a puzzle!
Many thanks for any swift reply.

Hi Friend ,
Please see this example how you can use the select DISTINCT statement
DATA: ITAB TYPE STANDARD TABLE OF SPFLI,
      WA LIKE LINE OF ITAB.
DATA: LINE(72) TYPE C,
      LIST LIKE TABLE OF LINE(72).
LINE = ' CITYFROM CITYTO '.
APPEND LINE TO LIST.
SELECT DISTINCT (LIST)
       INTO CORRESPONDING FIELDS OF TABLE ITAB
       FROM SPFLI.
IF SY-SUBRC EQ 0.
LOOP AT ITAB INTO WA.
    WRITE: / WA-CITYFROM, WA-CITYTO.
ENDLOOP.
ENDIF.

SELECT DISTINCT only on some fields but returning other fields.

As the thread says I need to select distinct rows with some fields but I need to show the associated data of other columns in the same table.
Simple Example
SUPPOSE THE TABLE INFO:
INFO(ID, NAME, TITLE, NUMBER, TELEPHONE, FAX, DESCRIPTION, TOPIC);
The table info could have null values in all the columns except for the ID. And there could be the same information for: Name, Title, Number, Telephone, Fax info in a lot of rows.
With the following statement I get distinct rows based on the name, title, number, telephone, fax and i get assured that the row with name in null is not returned.
SELECT DISTINCT P.NAME, P.TITLE,P.NUMBER,P.TELEPHONE,P.FAX FROM INFO P WHERE TRIM(P.NAME) IS NOT NULL;
returns 1400 rows;
The problem is that I need the DESCRIPTION and TOPIC columns of the 1400 distinct rows.
I have tried the following, but without sucess because the statement is returning 1350 rows, so there are 50 rows losted:
SELECT P.NAME, P.TITLE,P.NUMBER,P.TELEPHONE,P.FAX, P.DESCRIPTION,P.TOPIC
FROM INFO P , (SELECT DISTINCT P.NAME, P.TITLE,P.NUMBER,P.TELEPHONE,P.FAX FROM INFO P WHERE TRIM(P.NAME) IS NOT NULL) R
WHERE P.NAME= R.NAME AND P.TITLE = R.TITLE AND P.NUMBER = R.NUMBER AND P.TELEPHONE = R.TELEPHONE AND P.FAX = R.FAX;
Could anybody give me some help?
pd: Don´t ask why the table has been designed in that way... I'm trying to fix that ¬¬
Edited by: user6483610 on Sep 1, 2010 6:29 PM

@Raj Mareddi: I have tried that aproach and it gives the ORA-00979: not a GROUP BY expression
@PhoenixBai: You put me to think... jajaja i haven't think about it, actually there are more distinct values if I put the DESCRIPTION and TOPIC values in the query and yes I was hoping that the query choose for me... So I think that theres no way, the quality of the data is really bad and I have to deal with it. Thanks anyway!
By oher hand theres no way to do this thing in Oracle? the aproach of Raj makes sense but the ORA-00979: not a GROUP BY expression says that you must remove the other columns that are not in the group by function.

Select distinct queries

Is it possible to do select distinct queries with Kodo/JDO? I have a table
of with a county field and a state field. There are obviously many counties
for each state. I'd like to get a list of just the states using a select
distinct query. Do I have to use JDBC or one of the query extensions to do
this?

Hi Abe
Can you show us the query you are executing that returns duplicateobjects?
String filter = " _measurements.contains(measurement) &&
measurement._labRef.startsWith(labRef)";
Query query = pm.newQuery(Sample.class, filter);
query.declareParameters("java.lang.String labRef");
query.declareVariables("SampleMeasurement measurement");
Collection samples = (Collection)query.execute("foo Name");
"Sample" contains a collection of "SampleMeasurement" objects in the field
"_measurements".
According to the log, the following SELECT statement is created:
SELECT t0.JDOID, t0.JDOCLASS, t0.JDOVERSION, t0.NAME0, ...
FROM kodo.SAMPLE t0
INNER JOIN kodo.SAMPL__MEASUREMENTS t1
ON t0.JDOID = t1.JDOID
INNER JOIN kodo.SAMPLEMEASUREMENT t2
ON t1.MEASUREMENTS_JDOID = t2.JDOID
WHERE (t2.LABREF LIKE ?)
[params=(String) foo Name%]
The query returns for every matching SampleMeasurement a Sample object.
These objects may be duplicates.
Best regards

I'd suggest you try with the MERGE statement, or alternatively, post some sample data (insert statements) and table DDL (create statements), with an 'expected output' description and we can try to help you build a suitable statement.

Hi, Dharma Raju Kondeti.
I found this in the SAP online help, hope this can help you.
Specifying Internal Tables
When you read several lines of a database table, you can place them in an internal table. To do this, use the following in the INTO clause:
SELECT ... INTO|APPENDING [CORRESPONDING FIELDS OF] TABLE <itab>
                          [PACKAGE SIZE <n>] ...
The same applies to the line type of <itab>, the way in which the data for a line of the database table are assigned to a table line, and the CORRESPONDING FIELDS addition as for flat work areas (see above).
The internal table is filled with all of the lines of the selection. When you use INTO, all existing lines in the table are deleted. When you use APPENDING; the new lines are added to the existing internal table <itab>. With APPENDING, the system adds the lines to the internal table appropriately for the table type. Fields in the internal table not affected by the selection are filled with initial values.
If you use the PACKAGE SIZE addition, the lines of the selection are not written into the internal table at once, but in packets. You can define packets of <n> lines that are written one after the other into the internal table. If you use INTO, each packet replaces the preceding one. If you use APPENDING, the packets are inserted one after the other. This is only possible in a loop that ends with ENDSELECT. Outside the SELECT loop, the contents of the internal table are undetermined. You must process the selected lines within the loop.

feng.

NVL(l.pr_lot_no,'zzzzz') C,
NVL(l.db_waf_qty,'99999') lotQty,

and l.pr_run_type = 'PR'
and l.db_shpmt_no = i.db_shpmt_no
and l.db_shpmt_no = t.db_shpmt_no
and l.db_item_no = t.db_item_no

t.db_cust_po, i.db_delv_cod2, l.db_lot_desc, i.db_shpmt_no,
p.oe_po_line
order by lotNum
the problem is that if I dont use SELECT DISTINCT at beginning
the result is like
F , LOTQTY , PONUM , POLINENUM
DP8568.00,25 ,BVI10080 ,1
DP8568.00,25 ,BVI10080 ,2

DP8568.00,25 ,BVI10080 ,1
DP8568.00,25 ,BVI10080 ,2 //pleae note the QTY and POLINENUM
Then if Add SELECT DISTINCT, the result will be
F ,LOTQTY , PONUM , POLINENUM
DP8568.00,25 ,BVI10080,1
DP8568.00,25 ,BVI10080,2
but I change the NVL(l.db_waf_qty,'99999') lotQty, statement to NVL((SUM( l.db_waf_qty)),'99999') lotQty,
this will give me the result
F ,LOTQTY, PONUM , POLINENUM
DP8568.00,75 , BVI10080 ,2
DP8568.00,125 , BVI10080 ,1
Which I excepted the result as

SELECT DISTINCT with LINQ

Hey,
I am trying to perform a SELECT DISTINCT COL1, COL2, COL3 FROM VIEW WHERE CONDITION using LINQ with ODAC 112030 but I get different results.
C#:
var s1 = context.Select(v=>new { v.COL1, v.COL2, v.COL3}).Where(...).Distinct();
Any ideas?

Hey,
I think this way works - with anonymous types:
context.Entity.Where(...).Select(ent => new { col1 = ent.COL1, ... }).Distinct();.
You can also do context.Entity.Select("distinct it.COL1, it.COL2").Where("..."); but one should be careful to add all necessary columns in select statement.

OraException from Command.ExecuteReader with SELECT DISTINCT

Hello
I am trying to fill an OraDataReader object from a OraCommand object.
It appears that whenever the statement includes a SELECT DISTINCT, the command fails (even though the SQL statement works fine when executed e.g. in TOAD)
Dim Conn As OraConnection = New Oracle.DataAccess.Client.OraConnection("[Valid connection string]")
Conn.Open()
Dim Command As OraCommand = New OraCommand()
Command.CommandType = CommandType.Text
Command.CommandText = "select DISTINCT nvl(SUBFAMILY_COMPETENCY_ID, 0) SUBFAMILY_ID, nvl(NAME, ' ') NAME, FAMILY_COMPETENCY_ID FAMILY_ID " & _

Command.Parameters.Add("@CL_ID", context.Session!CLID)
Command.Parameters.Add("@LANGUAGE_ID", context.Session!LANGUAGEID)
Dim DataReader As OraDataReader = Command.ExecuteReader(CommandBehavior.CloseConnection)
An Oracle.DataAccess.Client.OraException is raised when executing the last statement, but no further details are given in the error message. The stack trace begins as follows

Oracle.DataAccess.Client.OraCommand.ExecuteReader(+737)

The exception disappears as soon as I remove the DISTINT keyword from my SQL statement.
Is this a bug or am I doing something wrong?
Thanks for help,

How to use a select statement with chinese characters?

I am currently developing a java servlet<using tomcat 4.x> which allows me to use select statement to retrieve results from the Microsoft SQL Server 2000 database. I am using a simple form to get the parameter for querying. The main problem i'm facing is that there are chinese information in the SQL database, but i can't retrieve it through the sql statement with the chinese characters input<thru the form with the help of NJ STAR>in the WHERE condition. When i execute the statement, it returns me no results even though the rows are present in the database.
Does anyone have the solution to using chinese words in the WHERE clause of the select statement to retrieve results with columns which contains chinese characters? Please help me. Thanks everyone. :)
PS: when i cut and paste those characters in the sql database and paste onto java.. it is ??? in questionmarks.. but when i paste them into excel 2000.. its shown as chinese chars again..
please heelppp~~

Greetings,
PS: when i cut and paste those characters in thesql
database and paste onto java.. it is ??? in
questionmarks.. but when i paste them into excelThis is why the SELECT is not returning any results.
You need to set the character encoding set on your
statement and parameters for the characters to be
properly translated. Refer to the charsetName
parameter in the String class constructor in your API
docs and also to
$JDK_DOCS/guide/intl/encoding.doc.html in your JDK
documentation.
2000.. its shown as chinese chars again..Because Office programs are performing the same kind
of character translation with the appropriate MS APIs.
please heelppp~~Regards,
Tony "Vee Schade" Cookis it possible for you to show me some coding examples? i don't really understand what is to be done in order to set the char set and what does it really do.. tried reading up but still dun understand.. :(
pardon my shallow knowledge of java..
ok..
The thing is when i used an insert statement with chinese characters of GBK format hardcoded into the java servlet and then i use the insert statement to insert the chars into the database, it cannot be seen as a chinese word when i off the NJStar. and then it can be searched out with my current form of servlet.. below is my coding of the servlet..
note: i've set my html file to charset = GBK
//prototype of Search engine...
//workable for GBK input and output...

with the above servlet i created, i can search out the data in the database which i've inserted through the insert statement. I still can't search for things i've keyed into the database directly using NJStar..
thank you so much for helping.. really hope any one else who knows the answer to this will reply too... thank you all so much...
