XMLForest: ALIAS specified in the AS clause

Hi,
I want to insert a variable into ALIAS specified in the AS clause of XNLForest function.
Is it possible ?
Documentation sais "partially escaped mapping is used."
Is anybody knows, is it possible to use variable
instead of simple "alias" ?
Thanks,
Viacheslav

I do not believe that the standard allows this....

There are fewer columns in the INSERT statement than values specified in the VALUES clause. The number of values in the VALUES clause must match the number of columns specified in the INSERT statement.

I have been looking at my code for hours now and cant figure out what is wrong. The error has kept popping up even when i thought i had fixed everything. maybe a second set of eyes could help me out here. If you could help me out it would be much appreciated.

Price Numeric (20) NOT NULL,
I do not think you understand this datatype? Go look at the values you are attempting to insert into this column. For example, "$29.99". After the insert, what value is actually stored in that column?
DateOfBirth Numeric (4) NOT NULL,
No. Just No. Either change the column name to faithfully represent what values you intend to store (and apply the appropriate constraints) or change the datatype and the values that you intend to store to match the column name. And the constraint
that you do have:
CONSTRAINT DateOfBirth
CHECK ([DateOfBirth] BETWEEN '1920-01-01' AND getdate() - 5844));
is both logically suspect and syntactically wrong. First, the upper boundary will be computed as 1999-04-29 15:50:21.670. But, of course, your column is a whole number of no more than 4 digits. The same issue applies to your lower boundary.
A simple select statement will show you those errors
select cast('1920-01-01' as numeric(4)), getdate() - 5844, cast(getdate() - 5844 as numeric(4));
An insert statement fails with the same error. Because, of course, your boundary values must actually be converted to numeric(4) in order to compare them against the value contained in the column. Generally, you can convert from
string to numeric - IF the content of the string actually contains a value that is numeric and can be converted into the specific type needed. Not so in this case. Is this 16 year period (5844 days) significant for some reason? You should
document it here in your DDL with a comment, because it is unlikely to be documented (and kept current) anywhere else.
And lastly, your script has:
SET IDENTITY_INSERT dbo.CUSTOMER OFF
That is not the name of your table, and therefore that statement also fails. The table name you used is plural.

The field name in the "items" entity model is "company" and on the database is "company_Id", neither will work.Using http://ajax.aspnetcdn.com/ajax/mobileservices/MobileServices.Web-1.2.5.min.jsWhat is wrong?
Regards

I see. Now works. So it would be like doing "SELECT ITEM,CATEGORY,COUNTRY, FROM TABLE WHERE CATEGORY='toy' AND COUNTRY='US'"
All rows will contain the "CATEGORY" and "COUNTRY" fields (or more), which is kind of redundant and bandwidth consuming.
Hope MS can change this.

Is it possible to create a view where table in the From clause changes name

is it possible to create a view from a from a table like this
create view my_view as select id, col1, col2, result from <<my_latest_cacahe_table>>;
the table in the from clause changes the name .
I have another table which indicates the the latest name of my cache tables. Always there are two records there. The latest one and previous one.
select * from cache_table_def
table_name cache_table_name refresh_date
my_table cache_table245 1/23/2012
my_table cache_table235 1/22/2012
create table cache_table_def (table_name varchar2(25), cache_table_name varchar2(25), refresh_date date);
insert into cache_table_def values( 'my_table','cache_table245','23-jan-2012');
insert into cache_table_def values ( 'my_table','cache_table546','22-jan-2012');
create table cache_table245 (id number, col1 varchar2(50), col2 varchar2(20), result number);
insert into cache_table245 values(1, 'test123', 'test345',12.12);
insert into cache_table245 values (2, 'test223', 'test245',112.12);
create table cache_table235 (id number, col1 varchar2(50), col2 varchar2(20), result number);
insert into cache_table235 values (1, 'test123', 'test345',92.12);
insert into cache_table235 values (2, 'test223', 'test245',222.12);
what I need to do is find the latest cache_table name for my_table and use that in my view defintion
When user select from the the view it always reurns the data from the latest cache_table
is it possible to do something like this in oracle 11g?
I have no control on the cache tables names. that is why I need to use the latest name from the table.
Any ideas really appreciated.

I've worked up an example that does what you ask. It uses the SCOTT schema EMP table. Make two copies of the EMP table, EMP1 and EMP2. I deleted dept 20 from emp1 and deleted dept 30 from emp2 so I could see that the result set really came from a different table.
-- create a context to hold an environment variable - this will be the table name we want the view to query from
create or replace context VIEW_CTX using SET_VIEW_FLAG;
-- create the procedure specified for the context
- we will pass in the name of the table to query from
create or replace procedure SET_VIEW_FLAG ( p_table_name in varchar2 default 'EMP')
as
begin
dbms_session.set_context( 'VIEW_CTX', 'TABLE_NAME', upper(p_table_name));
end;
-- these are the three queries - one for each table - none of them will return data until you set the context variable.
select * from emp where 'EMP' = sys_context( 'VIEW_CTX', 'TABLE_NAME' );
select * from emp1 where 'EMP1' = sys_context( 'VIEW_CTX', 'TABLE_NAME' );
select * from emp2 where 'EMP2' = sys_context( 'VIEW_CTX', 'TABLE_NAME' )
-- this is how you set the context variable depending on the table you want the view to query
exec set_view_flag( p_table_name => 'EMP' );
exec set_view_flag( p_table_name => 'EMP1' );
exec set_view_flag( p_table_name => 'EMP2');
-- this will show you the current value of the context variable
SELECT sys_context( 'VIEW_CTX', 'TABLE_NAME' ) FROM DUAL
-- this is the view definition - it does a UNION ALL of the three queries but only one will actually return data
CREATE VIEW THREE_TABLE_EMP_VIEW AS
select * from emp where 'EMP' = sys_context( 'VIEW_CTX', 'TABLE_NAME' )
union all
select * from emp1 where 'EMP1' = sys_context( 'VIEW_CTX', 'TABLE_NAME' )
union all
select * from emp2 where 'EMP2' = sys_context( 'VIEW_CTX', 'TABLE_NAME' )
-- first time - no data since context variable hasn't been set yet
SELECT * FROM THREE_TABLE_EMP_VIEW
-- get data from the EMP table
exec set_view_flag( p_table_name => 'EMP' );
SELECT * FROM THREE_TABLE_EMP_VIEW
-- get data from the EMP2 table
exec set_view_flag( p_table_name => 'EMP2');
SELECT * FROM THREE_TABLE_EMP_VIEW
For your use case you just have to call the context procedure whenever you want to switch tables. You can union all as many queries as you want and can even put WHERE clause conditions based on other filtering criteria if you want. I have used this approach with report views so that one view can be used to roll up report data different ways or for different regions, report periods (weekly, quarterly, etc). I usually use this in a stored procedure that returns a REF CURSOR to the client. The client requests a weekly report and provides a date, the procedure calculates the START/END date based on the one date provided and sets context variables that the view uses in the WHERE clause for filtering.
For reporting it works great!

CAN I PASS A TABLE NAME AS A VARIABLE IN THE FROM CLAUSE?

For some reason, I am trying to use a variable name containing the actual table name in the from clause and it won't allow me. I keep getting the error saying I need to declare the variable I'm using eventhough I've used it in another statement that is not the FROM clause.
Example
SELECT count(col1), sum(col2)
FROM v_table_name;
v_table_name was declared as:
v_tablename VARCHAR2(20);
v_tablename := real_table_name;
Is it not allowed to use variables in the FROM clause or am I missing something here?

You can use the Forms "From Clause Query" as the datasource for the data block. Then you can change the QUERY_DATA_SOURCE_NAME using set_block_property, so you can use any SQL statement you like. Of course you must name/alias the columns in a consistent manner so that the number of database items on the block matches those being queried.

How to construct the where clause for a nested xml target file

Post Author: jlpete72
CA Forum: Data Integration
I'm having some problems getting the desired results creating a multi-level nested xml file. Specifically, it does not seem that the where clause in the child schemas respects values from parent schemas. I'm sure I'm constructing something incorrectly, but am running out of ideas.
I am working with the classic company/order/line hierarchy and there are three levels of output schemas in my target xml file, one for company, order header and order line information.
For testing, I have hardcoded a restriction at the order header line to deal with only one order. But unless I hardcode values into the where clause at the order line level of the schema, all values are returned for orders belonging to the company defined in the company level.
I'm trying a where clause at the order line level similar to:
order_line.customer = order_header.customer and order_line.order_num = order_header.order_num
If the customer has more than one order in the data file, then all orders for that customer are placed in the detail for the order header. Only if I hard code the order number in the where clause do I get only the lines for the order specified in the header section. Not very practical.
What am I missing?

An External Parsed Entity could be used to reference a schema.
In your DTD:
<!ENTITY datamodules SYSTEM "file:///c:/Datamodules/Datamodules.xsd">
Refer the external entity in xml document:
<datamodules>&datamodules;</datamodules>

UPDATE using a second table for the Where Clause

Hi There,
Hoep someone can help me!
I am attempting to update a field in Tbl.1 to a known value. However, i want to use another table to specify WHICH records to update.
in this case i want to use table early_provider to obtain the value 'HCR' then pass that to the UPDATE clause in order to SET early_provisions.type_name = 'HOMC'
I hope this makes sense.
UPDATE EARLY_PROVISIONS eps
SET TYPE_NAME = (SELECT *
FROM EARLY_PROVIDER ep
WHERE PROVIDER_TYPE = 'HCR'
WHERE EP.PROVIDER_ID = EPS.PROVIDER_ID);
I need to be able to include the field value 'HOMC in this statement but am not sure how, or if i am barking up the wrong tree.
Much appreciated in advance

I should be selecting about 200 recordsd from early_provider that have the provider_type = 'HCR'
??I don't know your data. So i cant answer that. But for what you asked i think thats the correct UPDATE statement. So i think you have to investigate your data to find what is going on.

Calling a function in the select clause.

I am using Oracle 11g.
I am trying to write a query like this
select name,age, sal, avg = avg_salary(age)
from customer
where sal >= avg;
However, I am not able to do so. What the query is trying to do is print the name, age and salary of every customer as well as the average salary for the customer's age where the customer's salary is greater than the average salary for his age.
Please help. Thanks.

Hi,
The way to assign a column alias is to put the alais after the expression. It makes your code clearer if you put the keyword AS after the expression and before the alias, but this is not required.
SELECT     name
,     age
,     sal
,     avg_salary (age)     AS avg_salary_age
FROM     customer
WHERE     sal     >= avg_salary (age)
;You can't reference a column alais in the same query where it is defined (except in an ORDER BY clause). If you want to reference the alias anywhere else (e.g., in the WHERE clause) you have to define it in a sub-query; then you can use it anywhere you want in the super-query, liek this:
WITH     got_avg_salary_age     AS
     SELECT     name
     ,     age
     ,     sal
     ,     avg_salary (age)     AS avg_salary_age
     FROM     customer
SELECT     *
FROM     got_avg_salary_age
WHERE     sal     >= avg_salary_age
;Since AVG is the name of a built-in function, there could be problems using it as a column alias. You could call it average, if you don't like avg_salary_age.

Spatial query inside the exists clause return ora-13226

The following does not work:
select b.state, b.county from counties b where exists
(select 's' from states a where a.state = 'New Jersey'
and mdsys.sdo_relate (b.geom, a.geom, 'mask=INSIDE querytype=WINDOW' ) = 'TRUE');
ERROR at line 1:

ORA-06512: at "MDSYS.MDERR", line 8
ORA-06512: at "MDSYS.SDO_3GL", line 302
ORA-06512: at line 1
The following does work:
select b.* from states a,
counties b where a.state = 'New Jersey'
and mdsys.sdo_relate (b.geom, a.geom, 'mask=INSIDE querytype=WINDOW') = 'TRUE';
I found bug 1243095 telling that this is not a bug but a limitation of the spatial operator. It cannot be invoked on a table that is not spatially indexed. In fact, the table is indexed but oracle cannot find the spatial index because table b(counties) is declared outside the EXISTS clause.
In my case, I use object table. I cannot use the workaround specified above because I should use the DISTINCT clause but I cannot define the MAP and ORDER function (this is a general query).
I've found another workaround :
select b.state, b.county from counties b where exists
(select 's' from states a where a.state = 'New Jersey'
and mdsys.sdo_relate (a.geom, b.geom, 'mask=CONTAINS querytype=WINDOW') = 'TRUE');
but sdo_relate still doesn't use the spatial index of table b (even if I specify it explicitely in the operator) and the query is very slow (more than 15 minutes).
Is there a better workaround ?

OK but I work in object model.
And if I don't use the EXISTS clause, I must use the distinct clause.(I used the exists because of that)
If I will to retrieve all the country that have at least a state beginning with the C letter, I will wrote :
select c.* from country c, table(c.states) s where s.column_value.name like 'C%';
(It is a simplified request to express the problem)
In this case, I must use the distinct clause to select one occurence of each country objet (one country may contains more than one state beginning with C).
select distinct c.* from country c, table(c.states) s where s.column_value.name like 'C%';
For that, I must define a MAP or ORDER function for EACH type used in the country object.
My first question is : I must retrieve all different country objects. Why the request doesn't use the MAP or ORDER function of the country type to distinct them ? Is there another syntax (or a hint) to express that ?
In this case, it will make an ORA-00932 : incoherent datatype because the type of the nested table column cannot contain map or order method.
Any suggestion ?
Thanks in advance.

Is there a way to use dynamic built string in the "from" clause

Hi all, im having one problem and now, im not sure how to solve it easily at all... :) Is there someone that would be so kind and put a eye on it? ..thx
I have plsql proc, in which i have a list of table_names. For each of that table i need to run a query that will retrieve me a list of values and for each of that value i need to do something.
If i can be more specific about the problem -> each of that table is built as key_column, value_columns, day,starttime. For a key per table there are 4 records per hour - every quarter. Im truncating those quarters to full-quarter (minutes => 0->14 = 0min; 15->29 = 15min, 30->44 = 30, 45->59=45)
example
i get for one key and specific hour four records at 15:01;15:16;15:31;15:46 => i truncate em to 15:00;15:15;15:30;15:45..Sometimes there is a problem with the tool that is generating those data for me, and one quarter could be moved a little - so i get data like 15:01;15:16;15:29;15:46 => after i truncate the times i get duplicates in second quarter. It also can happen like this : 23:00; 23:14; 23:29; 23:44; 23:59 => totaly bad => cos the last one supposed to be as 0:00 next day, ..and 23:14 as 23:15...So...that was a problem - and solution -> i wanted to create plsql that will find those hours in each table i ve defined, and for each problem hour i make some fixes - update the bad time ...
..and i have problem - can i put an dynamic built table_name in the "from" clause?
example how i wanted to do that:
declare
     type t_objectName     is table of varchar2(030) index     by pls_integer;
     l_tableName              t_objectName;
begin
l_tableName(1) := 'tmphlrgl';
l_tableName(2) := 'tmprcfgl';
l_tableName(3) := 'tmprcfbs';
l_tableName(4) := 'tmpvlrgl';
for i in (select evtime from (select day,trunc_quarter(evtime) evtime,m_id from l_tableName(i) group by day,trunc_quarter(evtime),m_id having count(*)>1) order by evtime) loop
--some other conditions and the update...
end loop;
end;
/I cannot use the l_tableName(i) for FROM ...get an error...I was thinking to build it as dynamic sql and execute immediate into some kind of object that can store mutliple lines, from which i would in the FOR cycle get the data...But im not sure if this could be done in plsql...
thanks for your time and help..

Function-based index with OR in the wher-clause

We have some problems with functin-based indexes and
the or-condition in a where-clause.
--We use Oracle 8i (8.1.7)
create table TPERSON(ID number(10),NAME varchar2(20),...);
create index I_NORMAL_TPERSON_NAME on TPERSON(NAME);
create index I_FUNCTION_TPERSON_NAME on TPERSON(UPPER(NAME));
The following two statements run very fast on a large table
and the execution-plan asure the usage of the indexes
(-while the session is appropriate configured and the table is analyzed):
1)     select count(ID) FROM TPERSON where upper(NAME) like 'MIL%';
2)     select count(ID) from TPERSON where NAME like 'Mil%' or (3=5);
In particular we see that a normal index is used while the where-clause contains
an OR-CONDITION.
But if we try the similarly select-statement
3)     select count(ID) FROM TPERSON where upper(NAME) like 'MIL%' or (3=5);
the CBO will not use the function-index I_FUNCTION_TPERSON_NAME and we have a full table scan in the execution-plan.
(This behavior we only expect with views but not with indexes.)
We ask for an advice like a hint, which enable the CBO-usage
of function-based indexes in connection with OR.
This problem seems to be artificial because it contains this dummy logic:
     or (3=5).
This steams from an prepared statement, where this kind of boolean
flag reduce the amount of different select-statements needed for
covering the hole business-logic, while using bind-variables for the
concrete query-parameters.
A more realistic (still boild down) version of our select-statement is:
select * FROM TPERSON
where (upper(NAME) like 'MIL%' or (NAME is null))
and (upper(FIRSTNAME) like 'MICH% or (FIRSTNAME is null))
and ...;

In the realistic statement you write :
select * FROM TPERSON
where (upper(NAME) like 'MIL%' or (NAME is null))
and (upper(FIRSTNAME) like 'MICH% or (FIRSTNAME is null))
and ...;
as far as i know, NULL values are not indexed, "or (NAME is NULL)" have to generate a full table scan.

Using if logic in the where clause of a select statement

I have a select clause. And in the select clause there is a variable all_off_trt that can be 'Y' or 'N'.
In the where clause I want to make it so that if a form variable is checked and all_off_trt is 'Y' then
exclude it else if the form variable isn't checked then select it no matter what all_off_trt is.
Is there any way to include either and if statement or a case statement within the where clause to acheive this? If not is there another way of doing it?
Basically I am looking for a case statement like this
case
when all_off_trt = 'Y' and mail_para.code = 'Y' then false
else true
end

Ok, so that really doesn't solve my problem. I have 3 different fields that I need to do that with. Each combining in a select statement to print an email list, as well as other thing limiting the where clause.
This is currently what I have, tested and working 100%.
cursor email_cur is
select unique p.email,s.all_off_trt,s.all_deceased,s.no_enroll
from participant p, trialcom t, ethics s
where p.status='A'
and p.surname=t.surname
and p.initials=t.initials
and s.trial_cd = t.tricom
and s.centre = t.centre
and p.email is not null
and (t.centre in (select code from mail_parameters where user_name=user and mail_para='CENTRE')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='CENTRE'))
and (t.tricom in (select code from mail_parameters where user_name=user and mail_para='TRIAL')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='TRIAL'))
and (t.role in (select code from mail_parameters where user_name=user and mail_para='ROLE')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='ROLE'))
and (p.country in (select code from mail_parameters where user_name=user and mail_para='COUNTRY')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='COUNTRY'))
and (t.represent in (select code from mail_parameters where user_name=user and mail_para='REPRESENT')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='REPRESENT'));
This is in a program unit that runs when a button is clicked. At the end of that I need to add on the 3 case statements that help further narrow down the selection of emails to be printed. Then it prints the emails selected from this statement into a file. So it has to be done right in the select statement. The three table variables are the all_off_trt, all_deceased, and no_enroll. The form has 3 checkboxes. One for each, that when checked (giving the variable associated with the checkboxes a value of 'Y') excludes all emails that have a 'Y' in the coresponding table variable.

Thr_create() returns -1 which isn't specified in the man page. What is -1?

Hello,
I'm for the first time experimenting with Solaris threads as I'm porting an AIX app. over to Solaris.
Anyhow, I have a sample program that creates a simple thread. For some reason, the return value of of the initial thr_create is -1, which isn't specified in the man page for thr_create. The man page lists the following return values, non of which are -1:
RETURN VALUES
Zero indicates a successful return and a non-zero value
indicates an error.
ERRORS
If any of the following conditions occur, these functions
fail and return the corresponding value:
EAGAIN The system-imposed limit on the total number
of threads in a process has been exceeded or
some system resource has been exceeded (for
example, too many LWPs were created).
EINVAL The value specified by attr is invalid.
If any of the following conditions are detected,
pthread_create() fails and returns the corresponding value:
ENOMEM Not enough memory was available to create the
new thread.
If any of the following conditions are detected,
thr_create() fails and returns the corresponding value:
EINVAL o stack_base is not NULL and stack_size is
less than the value returned by
thr_min_stack(3T).
o stack_base is NULL and stack_size is not
zero and is less than the value returned by
thr_min_stack(3T).
However, I don't see a -1 there and therefore, don't know what this means.
Here is the simple code that I wrote for this experiment as well as the output. It doesn't get too far into the program before exiting - I've bolded where it exits:

Thanks for your response,

ok, my bad. I wasn't linking in the -lthread library.
Thanks anyway.
