BAfor clarity and easy to be read i attempted to rearrranged your code and this is what it will look like:
select *
from (select myrows.*, rownum rn
          from (select acc as account,
                       es as identity,
                       address as street_address
                       state as stae,
                       select id
                  from mytable
                 where emp_id = ? as my site from myview where ert_id=? and chek=?apparently the syntax is not correct and by that you are missing some comma in your column, ? question mark symbol will not be recognize, and some ')' closed parenthesis.
are you using a report builder that you want to use a placeholder column?

Error by using database procedure in select statement

hi ,
I have built a database procedure having one parameter with in out varchar type. that return value with some addition.
i am using it with some column in select statement only for display purpuses but i am facing error by doing that in select statement. that procedure is working well with bind variable but not with select statement.
plz help me how i can use a procedure in select statement. or can i do it or not.

plz help me how i can use a procedure in select statement. or can i do it or not.A workaround could be to create a wrapper function for your procedure. One that only passes the input parameters and returns the output parameter.
The simply call this function in your select which internally calls the procedure.

Can i join these sql select statement in one

Hi All,
Can i join this two select statement in to one select statement.
select username from dba_users where username like 'SAP%%%'; # to the Schemaid of the below /BMC/YGO_CPROD.
select YOP_PRD_NM, YOP_VERS from <schemaid>."/BMC/YGO_CPROD"; # To know a version from the table.
I am using this in a script can any help to join the above select statements into one.
Schemaid should be passed to this select YOP_PRD_NM, YOP_VERS from <schemaid>."/BMC/YGO_CPROD"; and i need to get output!
Thanks a lot

Are you asking about using the output of one query as the input to the WHERE clause of another?
If so look at the demos here: http://www.psoug.org/reference/conditions.html
PS: There is zero value in the construct 'SAP%%%'
What is it you are trying to do?
One "%" wildcard is sufficient.

How to use SET ID in select statement of SQ02

Hi,
I have a infoset, where for one of my Zfield, i have writen a select statement in order to get my ouput.
if aufk-aufnr = 'XYZ'.
select sum( FKBTR ) from fmifiit into zfmifiit
where fikrs = aufk-kokrs
and fipex IN capex
and wrttp NE '51'.
endif.
For the above statement, i have created (with 10 single values, table name FMCI, field name FIPEX) a SET id named CAPEX and used with IN operator.
But when i generating the infoset i am getting error like below
The IN operator with "CAPEX" is followed neither by an internal table nor by a value list
I was using IN opeartor for set ids during validation / substitutions, where if i have to validate multiple single values.
What to do here?

Using java function in select statement

Hi,
I am trying to use java function in select statement.
public class ClassA{
     private static String MyConst = "foo";
     public static String functionA(){
          return MyConst;
in my query I have:
select
     ClassA.functionA() AS id,
     groupId AS newID,
from
     myChannel[now]
ClassA is part of the application (no need to import).
I get and error of Invalid Expression on ClassA.functionA().
I also tried to declare the function in the processor element:
<wlevs:processor id="proc">
     <wlevs:function function-name="A" exec-methode="functionA">
          <bean class="mtPackage.ClassA"/>
     </wlevs:function>
<wlevs:processor>
but then I get a different error in the processor XML file: "An InvocationTargetException was encoutered while attemting to register the user defind function A. The message was null"
What am I missing here?

Hi,
From the above description, you have tried two manners to call method functionA() in the user defined class ClassA. One uses java cartridge manner directly and the other try to use user defined function manner.
For the java cartridge manner, the following CQL query should work if the ClassA is really included in the OEP app. I have done similar test before, it works.
select
     ClassA.functionA() AS id,
     groupId AS newID,
from
     myChannel[now]
For user defined function manner, I think two things you need to change:
1. Need to declare the function in the EPN assembly file(under META-INF/spring/), not component configuration file(under META-INF/wlevs/). The following is an example:
<wlevs:processor id="proc">
     <wlevs:function function-name="A" exec-methode="functionA">
          <bean class="mtPackage.ClassA"/>
     </wlevs:function>
</wlevs:processor>
2. Call the user defined function in the CQL query in the component configuration file under processor. For example:
select A() from myChannel

Use of wildcard * in SELECT statement

I have read that the use of the wildcard * in a SELECT statement cannot be utilized when using the INSERT INTO or other queries where data column/field alignment is critical. I have noted that the INSERT INTO column/fields must be in the same order
as the SELECT statement (as there is no alignment to column/field names). Can someone please provide me with the information or article that covered this scenario?

It is consider a good practice to specify columns name, however , SQL Server is smart enough to insert the data without too , but only if the table does not have an IDENTITY property
CREATE TABLE #t (c1 int, c2 char(1),c3 real, c4 bit)
CREATE TABLE #t1 (c1 int, c2 char(1),c3 real, c4 bit)
---Same thing with INSERT like SELECT * you asked
INSERT INTO #t1 VALUES (1,'A',2.5,0)
INSERT INTO #t1 VALUES (2,'B',3.5,1)
INSERT INTO #t1 VALUES (3,'C',4.5,0)
INSERT INTO #t SELECT * FROM #t1
SELECT * FROM #t

Using Variables in a select statement through a Database Adapter

I was wondering how I reference a variable in a select statement through a Database Adapter.
Ex.
1. I have a global variable that stores an employee number
2. I want to select an SSN # from a table based on an employee #
variable.
select ssn from emp where ssn = :input_variable - ????
- how do i reference the variable - I am getting a 'missing IN or OUT parameter error?
Any advice is much appreciated.
~Thanks

I'm just wondering if anyone knows a work around so that I might be able to store a Table's FIELD name in a variable or an array[] so that I can do a query based on the decision of a loop without having to code 10 IF/ELSE statements.For instance, although the above code will not work, this code, although quite lengthy, does:
If DataGrid1.SelStartCol = 0 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES__PUR_DT"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 1 Then
Adodc1.RecordSource = "Select * from tblReservation order by VENDOR"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 2 Then
Adodc1.RecordSource = "Select * from tblReservation order by VEN_LOC"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 3 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_TYPE"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 4 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_FROM_DT"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 5 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_TO_DT"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 6 Then
Adodc1.RecordSource = "Select * from tblReservation order by MISC_ADJ"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 7 Then
Adodc1.RecordSource = "Select * from tblReservation order by STATE_TAX"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 8 Then
Adodc1.RecordSource = "Select * from tblReservation order by LOC_CHARGE"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 9 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_ID"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 10 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_OP"
Adodc1.Refresh
End If
Do you see where i'm going with this?
I simple want to use a variable in the "select * from <Table> Order by <Field>"

Problem - Creating a Dynamic LOV using duplicate value in select statement

I am trying to create a Dynamic LOV by attempting to follow a pattern similar to the following:
select shop_name d, shop_id r
from shops
order by 1
However, I want to use the shop_name twice as in the following because I do not have any other unique identifier available such as a shop_id to associate with the shop name:
select shop_name d, shop_name r
from shops
order by 1
But I get an error where I am not allowed to duplicate the shop_name in the select statement. I read somewhere on this forum where it can be done but I can't find exactly how.
Can someone tell or show me how to accomplish this?
Thanks in anticipation for your answer.
Thanks,
Ric

Ric,
I just tried to do this on APEX 3.0, and it worked just fine with this SQL:
select ename d, ename r from emp order by 1Perhaps you could put an example on apex.oracle.com or specify the error message that you're getting.
So as long as you have uniquely aliased both columns, this should not present a problem.
Thanks,

Using Nested Table in Select Statement

Hi all ,
Can i use the PL/SQL nested table or Varray
in the select statement as a normal table joined with other database tables.
i.e.
I have a nested table NT_1 in PL/SQL proc
i have to use this NT_1 in the select statement as
select xxx from
tab_1,
tab_2,
NT_1
where
< some conditional joins >.
Please help me in this regard.

you can not use a varray as part of a SQL Statement in order to build joins.
Can you explain better what do you want to do ?

[php+mysql] how to use variables in a select statement?

Hi all,
I'm searching for a way to use a variable in the select
statement of mysql
query.
I have this variable that can contain:
$var=field_1 field_2 field5
or
$var=field3 field4 field8
so, the variable content is not always the same.
I would like to filter a table selecting only the columns
specified by the
current $var content.
Is this possible to do something like this?
$var=field1 field5 field10
SELECT string_to_array($var)
FROM mytable
ORDER BY mysortfield ASC
Or, is there another way to select columns dynamically?
Thanks for any suggestion.

Can we write function in select statement?

i have function and it has Out parameter,so in this case can i write select statement for my function to retrieve the value?

Or, you could use pipelined function - i guess.

What is the change occured by using the package in select statement

Hi all,
Can some one please tell me using the following package in the select statement of the view does it restricts the data or fetches the data
what is the change occurred using the package for fetching the date column
hr_discoverer.check_end_date (per_assignments_f.effective_end_date)
Thanks in advance

You can check the code -
-- this function checks to see if a date is equivalent to the end of time(31-Dec-4712)
-- if this is true it will return null else the actual end-date

Using Multiple Parameters in Select Statement

My goal is to be able to use more than one parameter for the select statement. When I use OR instead of AND it works but with only one parameter. I thought using AND would return any parameter that is listed in the ?Report Based On}. Any ideas why this will not work?
I've created four parameters:
Report Based on (string) Allow Multiple Values (Default Values: Customer, Part Id, and Serial Number)
RMA info by Customer (string)
RMA Info by Part Id (string)
RMA Info by SN (string)
This is my select statement
(if {?Report Based On} = "Customer" then
    {RMA_Information.Customer}LIKE{?RMA info by Customer})
and
(if {?Report Based On} = "Part Id" then
{RMA_Information.Part Id}LIKE{?RMA Info by Part Id})
and
(if {?Report Based On} = "Serial Number" then
{RMA_Information.Serial Number}={?RMA Info by SN })
tx Shirley

Try this...
IF "Customer" IN {?Report Based On} AND
     "Part Id" IN {?Report Based On} AND
     "Serial Number" IN {?Report Based On}
THEN {RMA_Information.Customer}LIKE{?RMA info by Customer} AND
     {RMA_Information.Part Id}LIKE{?RMA Info by Part Id} AND
     {RMA_Information.Serial Number}={?RMA Info by SN}
ELSE
IF "Customer" IN {?Report Based On} AND
     "Part Id" IN {?Report Based On}
THEN {RMA_Information.Customer}LIKE{?RMA info by Customer} AND
     {RMA_Information.Part Id}LIKE{?RMA Info by Part Id}
ELSE
IF "Customer" IN {?Report Based On} AND
     "Serial Number" IN {?Report Based On}
THEN {RMA_Information.Customer}LIKE{?RMA info by Customer} AND
     {RMA_Information.Serial Number}={?RMA Info by SN}
ELSE
IF "Part Id" IN {?Report Based On} AND
     "Serial Number" IN {?Report Based On}
THEN {RMA_Information.Part Id}LIKE{?RMA Info by Part Id} AND
     {RMA_Information.Serial Number}={?RMA Info by SN}
ELSE
IF "Customer" IN {?Report Based On}
THEN {RMA_Information.Customer}LIKE{?RMA info by Customer}
ELSE
IF "Part Id" IN {?Report Based On}
THEN {RMA_Information.Part Id}LIKE{?RMA Info by Part Id}
ELSE
"Serial Number" IN {?Report Based On}
THEN {RMA_Information.Serial Number}={?RMA Info by SN}
