Equivalent of to_date function in Ms SQL and using it in Evaluate function

Hi,
I am trying to find out a function in MS SQL which is equivalent to to_date function in oracle. Please find below the advanced filter i am trying to use in OBIEE.
Evaluate('to_date(%1,%2)' as date ,SUBSTRING(TIMES.CALENDAR_MONTH_NAME FROM 1 FOR 3)||'-'||cast(TIMES.CALENDAR_YEAR as char(4)),'MON-YYYY')>=Evaluate('to_date(%1,%2)' as date,'@{pv_mth}'||'@{pv_yr}','MON-YYYY') and Evaluate('to_date(%1,%2)' as date ,SUBSTRING(TIMES.CALENDAR_MONTH_NAME FROM 1 FOR 3)||'-'||cast(TIMES.CALENDAR_YEAR as char(4)),'MON-YYYY') <=timestampadd(sql_tsi_month,4,Evaluate('to_date(%1,%2)' as date,'@{pv_mth}'||'@{pv_yr}','MON-YYYY'))
The statement above works fines with oracle DB with to_date function. The same statement throws an error with MS SQL since to_date is not a built in function.
With MS SQL I tried with CAST, not sure how to pass parameters %1 and %2.
Please help me how to use Evaluate function and passing parameters along with to_date funtion in MS SQL.
Regards!

Hi,
please refer to this thread for useful information on using to_char and to_date functions of oracle in MS SQL server:
http://database.ittoolbox.com/groups/technical-functional/sql-server-l/how-to-write-to-to_char-and-to_date-sql-server-351831
Hope this helps.
Thanks,

Need a function name for Sql and Oracle

Retrieving value of next line by doing opteration in previous row.

Can you rephrase the question? Or better yet, provide an example? I'm not sure I understand what you are asking.
My best guess is that you are looking for the analytic functions LEAD or LAG in Oracle, assuming you are on a relatively recent Oracle version. If by "SQL and Oracle" in your subject you mean "SQL Server and Oracle" (SQL is a language that all relational databases implement, SQL Server is Microsoft's relational database), I have no idea how (or if) you can do something similar with a built-in function in SQL Server. You would want to post in a SQL Server group to see how they handle that sort of thing.

Dynamic SQL and use of aggregate functions

Hello Forum members,
I'm trying to create dynamic SQL in a function module and return the MAX value of a field.
I am passing in a parameter called CREATE_FIELD_NAME, and my SQL is
SELECT MAX(CREATE_FIELD_NAME) INTO (CREATE_DATE) FROM (TABLE_NAME).
I also tried:
SELECT MAX((CREATE_FIELD_NAME)) INTO (CREATE_DATE) FROM (TABLE_NAME).
But abap is not recognizing my variable as a variable in either case, but rather, as a field name.
Anyone know a way around this?
Thanks in advance,
Jeff
Here is my program:
FUNCTION ZJLSTEST4.
""Local Interface:
*" IMPORTING
*"     VALUE(TABLE_NAME) LIKE MAKT-MAKTX
*"     VALUE(CREATE_FIELD_NAME) LIKE MAKT-MAKTX
*"     VALUE(UPDATE_FIELD_NAME) LIKE MAKT-MAKTX
*" EXPORTING
*"     VALUE(MAX_DATE) LIKE SY-DATUM
DATA: CREATE_DATE LIKE MCHA-ERSDA VALUE '19000101',
      UPDATE_DATE LIKE MCHA-LAEDA VALUE '19000101'.
SELECT MAX(CREATE_FIELD_NAME) INTO (CREATE_DATE) FROM (TABLE_NAME).
ENDSELECT.
*SELECT MAX((UPDATE_FIELD_NAME)) INTO (UPDATE_DATE) FROM (TABLE_NAME).
*ENDSELECT.
IF CREATE_DATE > UPDATE_DATE.
   MAX_DATE = CREATE_DATE.
ELSE.
   MAX_DATE = UPDATE_DATE.
ENDIF.
IF MAX_DATE = '19000101'.
MAX_DATE = SY-DATUM.
ENDIF.
ENDFUNCTION.

Max is right, you need the spaces, as in my example.
You might like to try this:
data: l_CREATE_FIELD_NAME) LIKE MAKT-MAKTX,
      l_UPDATE_FIELD_NAME) LIKE MAKT-MAKTX.
DATA: CREATE_DATE LIKE MCHA-ERSDA VALUE '19000101',
UPDATE_DATE LIKE MCHA-LAEDA VALUE '19000101'.
concatenate 'MAX(' create_name ')' into l_create_name separated by space.
concatenate 'MAX(' update_name ')' into l_update_name separated by space.
SELECT SINGLE (l_CREATE_FIELD_NAME)
INTO CREATE_DATE FROM (table_name).
SELECT SINGLE (l_updATE_FIELD_NAME)
INTO updATE_DATE FROM (table_name).
IF CREATE_DATE > UPDATE_DATE.
MAX_DATE = CREATE_DATE.
ELSE.
MAX_DATE = UPDATE_DATE.
ENDIF.
IF MAX_DATE = '19000101'.
MAX_DATE = SY-DATUM.
ENDIF.
If it still fails please post the latest abap code for us to check.

Help on CAST function, defining TYPE TABLE and using a REF cursor

Hi,
I have written a procedure (lookup) inside a package (lookup_pkg) as shown below.
Procedure has an output variable of type PL/SQL TABLE which is defined in the package.
I want to write a wrapper procedure lookupref to the procedure lookup to return a ref cursor.
CREATE OR REPLACE PACKAGE lookup_pkg AS
TYPE t_lookup_refcur IS REF CURSOR;
CURSOR c_lookup IS
     Select columns1,2,3,....100
               FROM A, B, C, D, E
               WHERE ROWNUM < 1;
TYPE t_lookup IS TABLE OF c_lookup%ROWTYPE;
Procedure lookup(id Number, o_lookup OUT t_lookup);
End lookup_pkg;
CREATE OR REPLACE PACKAGE BODY lookup_pkg As
Procedure lookup(id Number, o_lookup OUT t_lookup) IS
BEGIN
END lookup;
Procedure lookupref(id Number, o_lookupref OUT t_lookup_refcur) IS
o_lookup t_lookup;
BEGIN
lookup(id, o_lookup t_lookup);
OPEN t_lookup_refcur FOR
SELECT *
     FROM TABLE(CAST(o_lookup AS t_lookup));
Exception
End lookupref;
END lookup_pkg;
When I compile this procedure, I am getting invalid datatype Oracle error and
cursor points the datatype t_lookup in the CAST function.
1. Can anyone tell me what is wrong in this. Can I convert a PL/SQL collection (pl/sql table in this case) to PL/SQL datatype table or does it need to be a SQL datatype only (which is created as a type in database).
Also, to resolve this error, I have created a SQL type and table type instead of PL/SQL table in the package as shown below.
create or replace type t_lookuprec as object
               (Select columns1,2,3,....100
               FROM A, B, C, D, E
               WHERE ROWNUM < 1);
create or replace type t_lookup_tab AS table of t_lookuprec;
CREATE OR REPLACE PACKAGE BODY lookup_pkg As
Procedure lookup(id Number, o_lookup OUT t_lookup) IS
BEGIN
END lookup;
Procedure lookupref(id Number, o_lookupref OUT t_lookup_refcur) IS
o_lookup t_lookup;
BEGIN
lookup(id, o_lookup t_lookup);
OPEN t_lookup_refcur FOR
SELECT *
     FROM TABLE(CAST(o_lookup AS t_lookup_tab));
Exception
End lookupref;
END lookup_pkg;
When I compile this package, I am getting "PL/SQL: ORA-22800: invalid user-defined type" Oracle error and
points the datatype t_lookup_tab in the CAST function.
2. Can anyone tell me what is wrong. Can I create a type with a select statement and create a table type using type created earlier?
I have checked the all_types view and found that
value for Incomplete column for these two types are YES.
3. What does that mean?
Any suggestions and help is appreciated.
Thanks
Srinivas

create or replace type t_lookuprec as object
(Select columns1,2,3,....100
FROM A, B, C, D, E
WHERE ROWNUM < 1);You are correct that you need to use CREATE TYPE to use the type in SQL.
However unless I am mistaken you appear to have invented your own syntax for CREATE TYPE, suggest you refer to Oracle documentation.

How to get the columns from SYS.ALL_COLUMNS and use it in COALESCE() Function.

Hi,
I have table called Employe. And the Columns are Emp_ID,EMP_NAME,SRC_SYS_CD,DOB
I have Query like
Select
COALESCE(MAX(CASE WHEN src_sys_cd='1' THEN Emp_id END), MAX(CASE WHEN src_sys_cd='2' THEN Emp_Id END))Emp_Id,
COALESCE(MAX(CASE WHEN src_sys_cd='1' THEN Emp_name END), MAX(CASE WHEN src_sys_cd='2' THEN Emp_Name END))Emp_name,
COALESCE(MAX(CASE WHEN src_sys_cd='1' THEN dob END), MAX(CASE WHEN src_sys_cd='2' THEN dob END))dob ,
from Employe
group by dob.
I want to generalize the query like get the columns from SYS.ALL_COLUMNS table for that table name and want to pass it to COALEACE() function. I tried with Cursor. But i didnt get the appropriate results.
Is there any way to achieve this? Please help me out in this regard.
Thanks,

Problem with function call from sql when using distinct

I have the following problem.
SELECT DISTINCT colA from tabA where my_function(colB) = 'TRUE'
This statement will return a handfull of results from a table with 70k + records. The function takes about 0.5 secs to execute.
How do i force the optimizer to do the select distinct first then execute the function on the results rather than execute the function for every single line first?
Thanks in advance
Keith

Let's compare some of those methods:

   ELSE
      RETURN 'FALSE';
   END IF;
END my_function;
Function created.

I just downloaded iPhoto 11 on my Mac and used the Import Pictures function that imported the photos, but I can open them in iPhoto. What do I need to do to resolve the problem?

I just downloaded IPhoto '11 for my iMac and updated my OS X to 8.2. I used the Import to Library function in iPhoto and the photos appeared to be importaing,however, the photos do not appear when I select last import or any other option in th eiPhoto menu. What do I need to do?

I used the Import to Library function in iPhoto and the photos appeared to be importaing
What were you trying to import and from where? You weren't trying to import an existing library into a new one were you? That is the wrong way to update a library!
When upgrading iPhoto just open the old library with the new application and let iPhoto update the library.
If that's not what you did explain in detail the workflow you followed after installing the new version of iPhoto.

Whats the functional difference between dbconole and using the Grid control.

I know this may seem like a strange question, but I was wondering if I only have one instance on my server, would benefit would i gain if I installed and configured the grid control
over the dbconsole that comes with the 11gr2?
I know the Grid control can discover many databases, but what else can it do that the dbconsole cannot?
thanks!

Hi,
Indeed good question.
It depends on installation type you selected. But are responsible for user administration in terms of creating, deleting, updating and role assignment tasks to users and groups.
--CUA is meant for ABAP Installation. CUA is responsible for entire landscape user administration works with RFC connection talking to all ABAP systems
--UME is meant for Java installations, plus UME is responsible for handling communication between ABAP users and java users.
UME

Unable to edit some functions in APEX Sql Workshop

When we press edit we get cursor in the code area and can edit some procedures, But for some procedures when we click edit we don't get cursor in the code area and we are not able to edit the functions/procedures.
I am using fairfox browser.This is happening with only some. Is there any security.grants issue???

Hi
This is happening with some procedures, For others this works fine.In IE I get red block in code area.

How to call a function with pl/sql

How does one call a function with pl/sql that uses a function?

Hi,
How does one call a function with pl/sql that uses a
function?I'm not sure what you mean.
In PL/SQL function can be used just about anywhere where an expression (with the same data type that the function returns). Arpit gave a very common example.
Here's another example, where all the functions take a single NUMBER argument and return a NUMBER, so they can all be used in places where NUMBERs are used:
IF fun_a (fun_b (0)) < fun_c (1)
THEN
    UPDATE table_x
    SET     column_y = fun_d (2)
    WHERE   column_z = fun_e (ROUND ((fun_f (3), fun_g (4)));You call a function simply by using its name, followed by its argument list, if any.
If the function is in a package, you must call it with the package name, like "pk_foo.bar (1, 2, 3)", unless the call comes from within the same package.
If the function is owned by someone else, you must give the owner name, like "scott.bar (SYSDATE)" or "scott.pk_foo.bar (1, 2, 3)". You can create synonyms to avoid having to name the owner.

SOLVED: How can I use or call a function that returns %ROWTYPE?

Hi
edit: you can probably skip all this guff and go straight to the bottom...In the end this is probably just a question of how to use a function that returns a %rowtype. Thanks.
Currently reading Feuerstein's tome, 5th ed. I've downloaded and run the file genaa.sp, which is a code generator. Specifically, you feed it a table name and it generates code (package header and package body) that will create a cache of the specified table's contents.
So, I ran:
HR@XE> @"C:\Documents and Settings\Jason\My Documents\Work\SQL\OPP5.WEB.CODE\OPP5.WEB.CODE\genaa.sp"
749 /
Procedure created.
HR@XE> exec genaa('EMPLOYEES');which generated a nice bunch of code, viz:
create or replace package EMPLOYEES_cache is
    function onerow ( EMPLOYEE_ID_in IN HR.EMPLOYEES.EMPLOYEE_ID%TYPE) return HR.EMPLOYEES%ROWTYPE;
    function onerow_by_EMP_EMAIL_UK (EMAIL_in IN HR.EMPLOYEES.EMAIL%TYPE) return HR.EMPLOYEES%ROWTYPE;
    procedure test;
end EMPLOYEES_cache;
create or replace package body EMPLOYEES_cache is
    TYPE EMPLOYEES_aat IS TABLE OF HR.EMPLOYEES%ROWTYPE INDEX BY PLS_INTEGER;
    EMP_EMP_ID_PK_aa EMPLOYEES_aat;
    TYPE EMP_EMAIL_UK_aat IS TABLE OF HR.EMPLOYEES.EMPLOYEE_ID%TYPE INDEX BY HR.EMPLOYEES.EMAIL%TYPE;
    EMP_EMAIL_UK_aa EMP_EMAIL_UK_aat;
    function onerow ( EMPLOYEE_ID_in IN HR.EMPLOYEES.EMPLOYEE_ID%TYPE)

        begin

        end;
    function onerow_by_EMP_EMAIL_UK (EMAIL_in IN HR.EMPLOYEES.EMAIL%TYPE)
        return HR.EMPLOYEES%ROWTYPE is
        begin
            return EMP_EMP_ID_PK_aa (EMP_EMAIL_UK_aa (EMAIL_in));
        end;
    procedure load_arrays is
        begin
            FOR rec IN (SELECT * FROM HR.EMPLOYEES)
            LOOP
                EMP_EMP_ID_PK_aa(rec.EMPLOYEE_ID) := rec;
                EMP_EMAIL_UK_aa(rec.EMAIL) := rec.EMPLOYEE_ID;

                EMP_EMAIL_UK_aa_rec := onerow_by_EMP_EMAIL_UK (rec.EMAIL);
                if rec.EMPLOYEE_ID = EMP_EMAIL_UK_aa_rec.EMPLOYEE_ID then
                    dbms_output.put_line ('EMP_EMAIL_UK lookup OK');
                else
                    dbms_output.put_line ('EMP_EMAIL_UK lookup NOT OK');
                end if;
            end loop;
        end test;
    BEGIN
        load_arrays;
    end EMPLOYEES_cache;
/which I have run successfully:
HR@XE> @"C:\Documents and Settings\Jason\My Documents\Work\SQL\EMPLOYEES_CACHE.sql"
Package created.
Package body created.I am now trying to use the functionality within the package.
I have figured out that the section
    BEGIN
        load_arrays;
    end EMPLOYEES_cache;
/is the initialization section, and my understanding is that this is supposed to run when any of the package variables or functions are referenced. Is that correct?
With that in mind, I'm trying to call the onerow() function, but it's not working:
HR@XE> select onerow(100) from dual;
select onerow(100) from dual
ERROR at line 1:
ORA-00904: "ONEROW": invalid identifier
HR@XE> select employees_cache.onerow(100) from dual;

ERROR at line 1:
ORA-00936: missing expressionHe provides the code genaa.sp, and a very brief description of what it does, but doesn't tell us how to run the generated code!
Now, I have just done some googling, and it seems that what I am trying to do isn't possible. Apparently %ROWTYPE is PL/SQL, and not understood by SQL, so you can't call onerow() from sql. Correct?
So I try wrapping the call in an exec:
HR@XE> exec select employees_cache.onerow(100) from dual;

Of course, now that I'm looking at it again, it seems that the way to go is indicated by the first error:
PLS-00428: an INTO clause is expected in this SELECT statement
So am I supposed to create a type of EMPLOYEES%ROWTYPE in a PL/SQL procedure, and the idea of this code, is that the first call to onerow() runs the initialiation code, which populates the cache, and all subsequent calls to onerow() (whether by my session or any other) will use the cache?
I've had a stab at this, but still, no joy:
create or replace procedure testcache is
    emp employees%rowtype;
    begin
        select employees_cache.onerow(100) from dual into emp;
        dbms_output.put_line('Emp id: ' || emp.employee_id);
    end testcache;
show errors
HR@XE> @testcache.sql
Warning: Procedure created with compilation errors.
Errors for PROCEDURE TESTCACHE:
LINE/COL ERROR
4/9      PL/SQL: SQL Statement ignored
4/54     PL/SQL: ORA-00933: SQL command not properly ended
HR@XE>Have a feeling this should be really easy. Can anybody help?
Many thanks in advance.

Ha, figured it out

Hopefully you also figured out that the example is just that: a technical example of how to use certain Oracle functionality. Unfortunately it is also an example of what you should NOT do in an actual application.
That code isn't scaleable, uses expensive PGA memory, has no limit on the amount of memory that might be used and, contrary to your belief will result in EVERY SESSION HAVING ITS OWN CACHE of exactly the same data if the session even touches that package.
Mr. Feuerstein is an expert in SQL and PL/SQL and his books cover virtually all of the functionality available. He also does an excellent job of providing examples to illustrate how that functionality can be combined and used. But the bulk of those examples are intended solely to illustrate the 'technical' aspects of the technology. They do not necessarily reflect best practices and they often do not address performance or other issues that need to be considered when actually using those techniques in a particular application. The examples show WHAT can be done but not necessarily WHEN or even IF a given technique should be used.
It is up to the reader to learn the advantages and disadvantages of each technicalogical piece and determine when and how to use them.

Now, I have just done some googling, and it seems that what I am trying to do isn't possible. Apparently %ROWTYPE is PL/SQL, and not understood by SQL, so you can't call onerow() from sql. Correct?

That is correct. To be used by SQL you would need to create SQL types using the CREATE TYPE syntax. Currently that syntax does not support anything similar to %ROWTYPE.

NO! That is a common misconception. Each session has its own set of package variables. Any session that touches that package will cause the entire EMPLOYEES table to be queried and stored in a new associative array specifically for that session.
That duplicates the cache for each session using the package. So while there might be some marginal benefit for a single session to cache data like that the benefit usually disappears if multiple sessions are involved.
The main use case that I am aware of where such caching has benefit is during ETL processing of staged data when the processing of each record is too complex to be done in SQL and the records need to be BULK loaded and the data manipulated in a loop. Then using an associative array as a lookup table to quickly get a small amount of data can be effective. And if the ETL procedure is being processed in parallel (meaning different sessions) then for a small lookup array the additional memory use is tolerable.
Mitigating against that is the fact that:
1. Such frequently used data that you might store in the array is likely to be cached by Oracle in the buffer cache anyway
2. Newer versions of Oracle now have more than one cache
3. The SQL query needed to get the data from the table will use a bind variable that eliminates repeated hard parsing.
4. The cursor and the buffer caches ARE SHARED by multiple sessions globally.
So the short story is that there would rarely be a use case where ARRAYs like that would be preferred over accessing the data from the table.

Error i am getting while using the evaluate function in a reprot

hi all,
can't we use semicolon in Evaluate function
Semicolon is not allowed in Evaluate Functions without proper escape i.e. \; (HY000)
SQL Issued: {call NQSGetQueryColumnInfo('SELECT case when 1=0 then USER_INFORMATION.USERNAME else EVALUATE(''my_func(%1,%2,%3)'',''aa'',''bb'',''Hindu;All Natl and Local'') end FROM xxx_xxx_xx')}
SQL Issued: SELECT case when 1=0 then USER_INFORMATION.USERNAME else EVALUATE('my_func(%1,%2,%3)','aa','bb','Hindu;All Natl and Local') end FROM xxx_yyy
Thnx

Hi,
Try this
EVALUATE('my_func(%1,%2,%3)','aa','bb','Hindu\;All Natl and Local')Without any proper escape character '\' obiee(EVALUATE function) will not accept ';'
Thanks,

Evaluate function error! how to use it properly?

Hi,
I used evaluate function to use a user-defined stored function present in my DB. But I ended up with this error.
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 17001] Oracle Error code: 1722, message: ORA-01722: invalid number at OCI call OCIStmtExecute: select distinct T119198.BCREFNO as c1, T119198.MATURITY_DATE as c2, T119198.BILL_DUE_AMT as c3, test_eval('"Contract BC Parameters Fact"."Bill Amt Lcy"') as c4 from BCTBS_CONTRACT_MASTER T119198 /* BC_BCTBS_CONTRACT_MASTER */ order by c1, c2, c3, c4. [nQSError: 17011] SQL statement execution failed. (HY000)
I used the following evaluate function in my report under Edit Column Formula of the particular field.
EVALUATE('test_eval(%1)','"Contract BC Parameters Fact"."Bill Amt Lcy"')
The test_eval function in my DB takes one parameter of type number and returns a number. The "Contract BC Parameters Fact"."Bill Amt Lcy" field is of DOUBLE type as found in BMM layer.
I wish to know if I am right by placing the evaluate function in report or should I use it in BMM layer? Can I get anybodies assistance in knowing how to arrive at using a DB user-defined function in a report.
Regards,
The MasterMind.

hi,
This is the syntax
*EVALUATE('DB_Function(%1)' as returntype, {Comma separated Expression})*

Installing Log4J in Tomcat and using JDBC to log errors

Has anyone figured out how to install Log4J in Tomcat and use the Log4J JDBC functionality?
I have log4j.jar in CATALINA_HOME/common/lib.
I also have log4j.properties is in CATALINA_HOME/common/classes
Then when I start Tomcat I get the following error:
[main] DEBUG org.apache.commons.digester.Digester - addRuleSet() with no namespace URI
is it something to do w/ the log4j.properties file? do i have to use a xml format or is it ok to use .properties format?
-Karthik

I would say you have something wrong in your log4j properties file.
properties format is fine, but I suspect something in there is not quite right.
Try starting with a simple example one, see if it works, and then try adding your own config based on that one.
Good luck,
