Using CAST Function in PL-SQL

Hello guys,
I'm writing a stored procedure which tries to convert a string representing a number to a fixed size number(with 2 positions fraction). For example, if the input was "15,456" the result would become 15.45.
I was able to aschieve this ussing the CAST function within a query as follows:
select cast ('15,456' as number(15,2)) from dual; -- (the comma in my case is configured as fraction separator). The previous query executes OK using a query analyzer like SQL Plus.
However, when I try to use the same function within a stored procedure, it will complain about the number's size (15,2) and wont compile.
v_importe_ingresado := CAST('15,456' AS NUMBER(15,2));
Error output: PLS-00103 found '(' but expected one of the following: .)@%
When removing the (15,2) it compiles ok
¿Any clue?
I will appreciate any help.
Thanks in advance,
Bernabé

¿Any clue?¿¿¿Over complication???
SQL> select round(15.456, 2), trunc(15.456, 2) from dual
2 /
ROUND(15.456,2) TRUNC(15.456,2)
15.46 15.45

ORA-00902: invalid datatype comile error while using CAST function

Hi everyone,
I'm getting ORA-00902: invalid datatype compilation error while using CAST function.
open ref_cursor_list for select empName from TABLE(CAST(part_t AS partnumberlist));
The partnumberlist and ref_cursor_list is declared in the Package spec as given below.
TYPE ref_cursor_list IS REF CURSOR;
TYPE partnumberlist IS TABLE OF emp.empName%TYPE;
The error points the partnumberlist as invalid datatype in TOAD because of this i'm unable to compile the package.
Any suggestion
Thanks and regards

CAST function in PL/SQL

Hello folks,
 
has anybody a reasonable explanation for this weird behaviour concerning the CAST function? 
I am using 9iR2. 
Following runs fine eventhough I would expect an error:

SQL> DECLARE
 i INTEGER;
 x VARCHAR2 (1) := 'x';
BEGIN
 i := CAST (1 AS x);
 DBMS_OUTPUT.put_line ('i=' || i);
END;
i=1
PL/SQL procedure successfully completed.
BUT simply hardcoding the "datatype" raises an error:

SQL> DECLARE
 i INTEGER;
 x VARCHAR2 (1) := 'x';
BEGIN
 i := CAST (1 AS 'x');
 DBMS_OUTPUT.put_line ('i=' || i);
END;
Error at line 11
ORA-06550: line 5, column 20:

 <an identifier> <a double-quoted delimited-identifier> LONG_
 double ref char time timestamp interval date binary national
 character nchar
The symbol "<an identifier> was inserted before "x" to continue.
Whats going on here?

It's trying to cast to x%type, which is DATE. But even if you replace it with DATE you get the same error.

Using max function in PL/SQL

VERY URGENT...
Am new to oracle...
I've written a package that display gif images in form of histogram/bar chart. using html,
I need to use max function to display values proportionately.
please help. i need to complete this assignment by 2/9/00 by 10.00 am at the latest. I've half written a function but I don't know if there's a simpler way fo doing this. html enabled

First of all Thanks to all gentlemen who replied ..many thanks ...
Tried the ROW_NUMBER() option but still it is taking time...have given output for the query and tkprof results as well. Even when it doesn't fetch any record ( this is a valid cased because the input header id doesn't have any workflow request submitted & hence no entry in the wf_items table)..then also see the time it has taken.
Looked at the RANK & DENSE_RANK options which were suggested..but it is still taking time..
Any further suggestions or ideas as to how this could be resolved..
SELECT 'Y', 'Y', ITEM_KEY
FROM
( SELECT ITEM_KEY, ROW_NUMBER() OVER(ORDER BY BEGIN_DATE DESC) RN FROM

Need help in using sleep function in pl/sql

Hi,
need help:
I have a condition where i want to validate total_pass=total_fail and
I want to use the sleep function in a pl/sql where i want to wait for 2 minutes ie.checking
whether total_pass=total_fail based upon class_id .
I have the data in the table as:
CLASS_ID TOT_PASS TOT_FAIL
1 10 10
2 5 4
3 6 6
4 7 5
Any help will be needful for me

I'm not quite sure what you are lookg for here, but whatever it is, your code as posted won't do it. You will never break out of the WHILE r_Class.Tot_Pass = r_Class.Tot_Fail loop, since these values will never change because you never get the next record form the cursor.
From your original data, it looks like your cursor will return multiple rows which implies to me that you want to fetch the first row from the cursor, check if tot_pass = tot_fail, if they are equal, sleep for two minutes then get the next row. This does not make sense to me. Once the select in the cursor is executed, the data it returns will not change due to Oracle's read consistency model, so there seems to me no point in the sleep.
The other alternative I can see is that you want to check all the returned rows, and if tot_pass = tot_fail for one of the rows (or possibly for all of the rows), then you want to sleep and try again.
If you can explain in words what it is you are trying to accomplish, someone will be able to point you to a solution.

How to use CAST function in obiee 11g in rpd

Hai,
I am trying to use the cast fucntion in rpd in bmm layer for a new logical column that I have created and is giving me error compile message.
Can any one please help me out or find out what is wrong in the function I am using.
The expression I am trying to use is
( CAST ( "Chase Card Acquisition"."Fact Deposit"."Base Earn" as decimal(18,0) ) + "Chase Card Acquisition"."Fact Deposit"."Tot Bonus Earn" )

Decimal is not a supported type in the logical layer. See:
http://docs.oracle.com/cd/E21764_01/bi.1111/e10540/sqlref.htm#BIEMG559
for supported types.
If you are casting as Int then do not specify the precision ('cast x as int' NOT 'cast x as int(y,z)'). Regards,
Robert

Using PowerShell Functions in t-SQL scripts

experts,
Can I use a power shell function that gets file size given file path by cross applying it to a table in SQL Server that holds file path of files?

Using NVL function in Dynamic SQL

Hi ,
I have created a procedure using the Dynamic SqL and while using the NVL() getting the following error . ORA-00936: missing expression.
The query I have written as
SQL_Txt:=' INSERT INTO VF.tblCData (A, B, C, D, E, F,G,H,I,J)
     SELECT '||l_A||',

          NVL('||Param3||',''''),
          NULL
          FROM '||ParamTbl1||' WHERE ' ;
and so on.
For Param1 I have data for one execution and Param2 and Param3 is null for that execution.
While executing the same I am getting below

Any suggestion to resolve this issue is highly appreciable.
Thanks

NVL(,''),Where's the first argument to NVL? That's the obvious problem. Empty strings are NULL in Oracle anyway, so just lose the NVL and insert the values...

Using CAST function to convert to timestamp

I have a select statement that runs via JDBC and is not using any index as timestamp is explicitly used. I would like to be able to convert to Date so the proper index can be used as this column is of Date datatype. I'm having "ORA-25137: Data value out of range" when I use "b.TRAN_DATE BETWEEN CAST(:1 AS DATE) AND CAST(:2 AS DATE) : instead of "b.TRAN_DATE BETWEEN :a and :b.
Could someone help with this as I really want our indexes to be used and therefore Date datatype should be used in the JDBC connection
Thanks

Below is the query that is not using the index b/c of the date datatype. Changing b.TRAN_DATE BETWEEN :1 AND :2 to b.TRAN_DATE BETWEEN CAST(:1 AS DATE) AND CAST(:2 AS DATE) gives "ORA-25137: Data value out of range" error.

How to use document() function in PL/SQL XSLT parser ?

The "XDB Developers Guide" documentation says on page 12-18
>
The application can use DBUriType objects:
To make references, such as import or include, to related XSL stylesheets. You can encode these references within the XSL stylesheet itself.
following this i added string like this to my stylesheet
<xsl:apply-templates select="document('/ORADB/SCOTT/STYLESHEET_TAB/ROW[ID=1]/STYLESHEET/text()')" mode="include"/>
<xsl:cinclude href="/ORADB/SCOTT/STYLESHEET_TAB/ROW[ID=1]/STYLESHEET/text()"/>
But when XSLT processor reaches this, it fails.
I also even tried like this
<xsl:include href="/ORADB/SCOTT/STYLESHEET_TAB/ROW[ID=1]/STYLESHEET/text()"/>
but result is the same ;(((
Generally - is there ANY way XSLT processor can deal with stylesheet which contains
DBURI references to another stylesheets stored in XMLTYPE columns ?
I'm currently in charge to develop a content management system for a huge corporate site,
so i'm VERY interested to know - does this feature really exists on Oracle 9.2 ?
Please ansver ASAP.

BTW: following this link
xsl:include within XSL stylesheet stored in XMLType column
i've encountered that this theme has been asked but none from Oracle staff has answered on it yet ;(((((((

Use percentage function in pl sql

Hi,
I want to get the employees that their salary are in top 13% of salaries.
I learned in this forum that I can get the 10% of top salaries in HR schema by this query:
WITH got_tenth AS
 SELECT last_name, salary
 , NTILE (10) OVER (ORDER BY salary) AS tenth
 FROM hr.employees
SELECT last_name, salary
FROM got_tenth
WHERE tenth = 10
ORDER BY salary DESC
;Output:
LAST_NAME SALARY
King 24000
Kochhar 17000
De Haan 17000
Russell 14000
Partners 13500
Hartstein 13000
Greenberg 12000
Errazuriz 12000
Higgins 12000
Ozer 11500There is no "TOP" keyword in Oracle.I wondered, What if I want to get, for example, the employees who are in the top 12% of the salaries? here we cannot use deciles (maybe we can but it won't be very nice).
Thanks a lot to helpers

CUME_DIST can help:
http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions035.htm
WITH tbl AS
SELECT last_name, salary
, cume_dist() OVER (ORDER BY salary DESC) AS cumulative_pcnt
FROM hr.employees
SELECT *
FROM tbl
WHERE cumulative_pcnt <=0.12;Tie values always evaluate to the same cumulative distribution value, so if you need exact 12% of the rows you can add employee_id in the ORDER BY list.

We are having a performance issue with the below logic wherein MAX is being used in order to get the latest instance/record for a given input variable ( p_in_header_id).. the item_key is having the format as :
p_in_header_id - <number generated from a sequence>
This query to fetch even 1 record takes around 1 minutes 30 sec..could someone please help if there is a better way to form this logic & to improve performance in this case.
We want to get the latest record for the item_key ( this we are getting using MAX (begin_date)) for a given p_in_header_id value.
Query 1 :
SELECT item_key FROM wf_items WHERE item_type = 'xxxxzzzz'
AND SUBSTR (item_key, 1, INSTR (item_key, '-') - 1) =p_in_header_id
AND root_activity ='START_REQUESTS'
AND begin_date =
(SELECT MAX (begin_date) FROM wf_items WHERE item_type = 'xxxxzzzz'
AND root_activity ='START_REQUESTS'
AND SUBSTR (item_key, 1, INSTR (item_key, '-') - 1) =p_in_header_id);
Could someone please help us with this performance issue..we are really stuck because of this
regards

First of all Thanks to all gentlemen who replied ..many thanks ...
Tried the ROW_NUMBER() option but still it is taking time...have given output for the query and tkprof results as well. Even when it doesn't fetch any record ( this is a valid cased because the input header id doesn't have any workflow request submitted & hence no entry in the wf_items table)..then also see the time it has taken.
Looked at the RANK & DENSE_RANK options which were suggested..but it is still taking time..
Any further suggestions or ideas as to how this could be resolved..
SELECT 'Y', 'Y', ITEM_KEY
FROM
( SELECT ITEM_KEY, ROW_NUMBER() OVER(ORDER BY BEGIN_DATE DESC) RN FROM
WF_ITEMS WHERE ITEM_TYPE = 'xxxxzzzz' AND ROOT_ACTIVITY = 'START_REQUESTS'
AND SUBSTR(ITEM_KEY,1,INSTR(ITEM_KEY,'-') - 1) = :B1
) T WHERE RN <= 1
