SQL Buffering class / function in Oracle??
Hi All:
Im trying to write a java program that can make SQL transactions such as insert, update etc. I have questions regarding ways on doing so with JDBC.
Does Oracle have some kind of Array buffer like java classes that can let me serialize this class object and send it over to the DB (or let me point to / subclass such a class)? This object could contain a collected set of SQL statements that I want to execute. Once this object arrives in the DB, the DB will take care of it and execute all the SQL statements in the object accordingly.
I know that I can just execute the SQL statements individually at runtime. However, the reason I want to do this is because maintaining a JDBC connection might be expensive and natural disasters and happen to this connection, so I want to minimize JDBC access as much as possible. Therefore wondering if Oracle supports this kind of function.
Please point me to related documents. Or if you have some other idea can help me to solve my problem.
Thank you in advance!!

Try writing a stored procedure. See oracle docs for details.

Service Bus 12c Class not found 'oracle.tip.pc.services.functions.ExtFunc'
Hi,
Did anyone came across this issue with Class not being found for XSLT Function used in transformer on 12c OSB.
I'm using oraext:sequence-next-val and have configured as below:
namespace-uri:http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.ExtFunc
namespace-prefix: oraext
Not sure why at runtime I'm getting below error, as the same was working fine in 11g OSB Domain.
XML-22045: (Error) Extension function error: Class not found 'oracle.tip.pc.services.functions.ExtFunc'Have you restarted servers after putting jar in $Domain_Home/lib directory? Also try after explicitly adding this jar in classpath by editing server startup script (startManagedWeblogic.cmd or .sh) or in domain env setting script (setDonainEnv.cmd or .sh) and restarting the servers.

Use T-SQL functions in ORACLE too, so you can write one script version that works in SYBASE, SQLSERVER and ORACLE when need to use the following functions:
ceiling, charindex, dateadd, datediff, datename, datepart, day, db_id, db_name, getdate, host_id, host_name, left, len, month, replicate, right, space, str, str_replace, stuff, substring, suser_id, suser_name, user_id, user_name and year.
The file [comp_tsql_ORA_schema.txt|http://forums.databasejournal.com/attachment.php?attachmentid=564&d=1258547015] creates the tablespace and schema to put the objects, and the file [comp_tsql_ORA.txt|http://forums.databasejournal.com/attachment.php?attachmentid=569&d=1259256898] creates the functions into the new schema. They will be avaliable for any schema of the oracle instance.
Hope this help!
Any suggestion please contact.

J2EE beta released around 1999. Religious programming wars far preceded that.

I'm no longer convinced that elegance is a desirable trait for a language. So call me a heretic.
Ever tried XLISP? :-)
It's different. Back then it was simply the language itself. And it was not really a religious kind of battle, but more a mine-is-bigger-and-better-than-yours one.
With Java, it is all about The Acrhitecture and the blessed language of Java. ;-)
I wouldn't so much blame J2EE believers for that. I think there is a fundamental complexity to web type paradigms that hasn't been described in a precise and encompassing enough manner to enable correct project planning.The basic problem is that the database is treated as a persistent storage layer only. A bit bucket. And that is exactly what a database is not.
But as it is used that, loads of database features now need to be duplicated in the application layer. Which is done. Very poorly.
Heck, I've even been told that J2EE's 3-tier architecture is not client server. Such ignorance is really unbelievable. Or is it pure stupidity?Until you just made me look it up, I would have thought that too, I'm sure I saw client/server defined as two-tier in the last century. But I have much more stupid misdefinitions to deal with on a daily basis, simply from the multiplicity of paradigms. I tend to retreat into my shell. Hehehe. Know that feeling... These days I rather run away, or set shields to full power, than try to get in yet another frustrating, fruitless and futile discussion with a Java head about the wonders of the J2EE architecture. Or trying to explain that this "new" architecture is predated with what we used in the 80's on mainframe systems with transaction monitors, block devices (the 80's web browsers) and databases - which software layer for software layer was almost identical to "+The Great Architecture+" of today. (and we did it without buzzwords too) ;-)
Client-server is a software architecture and in essence describes 3 basic software components. The User Interface (UI), the Application (APP) and the Database (DB). And there are various ways to put these components together in a client-server architecture. The mistake that the Java fanbois make is thinking that client-server means having the client as the UI and APP as a single component (so-called fat client) and then the DB component as the server.
There are numerous versions of these - including the APP component being a server component (as we now these days more commonly used in over the web).
My beef with the J2EE "+religion+" always has been that client-server is client-server. The fundamentals stay the same. -
Access SQL Function in Oracle?
Microsoft Access SQL has a function called LastOf which extracts
data from a column within the last row returned when multiple
rows are returned. This function works even when many tables are
joined and only one of them returns multiple rows. Does Oracle's
SQL implementation have anything like it?I can't find a reference to a LastOf function for MS-Access.
Perhaps you are refering to the Last(expr) function or MoveLast
method of DAO Recordset.
Last behavior can be reached in one of several ways depending on
the desired results, most depending on the ordering of the result
set. Both Access and VB use the concept of a recordset, which is
analogous to a CURSOR in Oracle.
To use an implicit cursor, and only retreive the one row, you
might use the sudo-colomn ROWNUM:
SELECT my_col FROM my_tab WHERE ROWNUM = 1
This would give you the first record of the result set, but there
is no guarantee on which row it would be - so you might consider
ordering the result set:
SELECT my_col FROM my_tab WHERE ROWNUM = 1 ORDER BY my_col ASC;
Which would return one row, the value of my_col being the
smallest value in the table. Now might be a good time to talk
aggrogate functions, such as:
SELECT MIN( my_col ) FROM my_tab;
which does the same thing as above.
If all else fails, RTFM.

Using the ALL_TAB_COLS table I want to list out certain fields for each table name specified.
All the tables have fields that are similar. I just want these table names to go across the top.
And the field names to list out under each table.
So you would have something like:
AAEADP1 AAMAET1 AAPMED1
SSN_SOURCE MPI_OLD EMPLOYEE_SSN
FIRST_NAME_SOURCE EMPLOYEE_SSN_SOURCE EMPLOYEE_FIRST_NAME
LAST_NAME_SOURCE EMPLOYEE_LAST_NAME_SOURCE EMPLOYEE_LAST_NAME
DOB_SOURCE EMPLOYEE_FIRST_NAME_SOURCE EMPLOYEE_DATE_OF_BIRTH
EMP_SSN_SOURCE EMPLOYEE_DOB PATIENT_SSN
EMP_FIRST_NAME_SOURCE PATIENT_SSN PATIENT_FIRST_NAME_SOURCE
EMP_LAST_NAME_SOURCE PATIENT_LAST_NAME_SOURCE PATIENT_LAST_NAME_SOURCE
EMP_DOB_SOURCE PATIENT_FIRST_NAME_SOURCE PATIENT_DOB
MPI PATIENT_DOB PRESCRIBER_LAST_NAME
SSN_STANDARDIZED EMPLOYEE_NON_SSN_ID MPI
FIRST_NAME_A_STANDARDIZED EMPLOYEE_SSN_STANDARDIZED PATIENT_FIRST_NAME_A_STD
FIRST_NAME_B_STANDARDIZED PATIENT_FIRST_NAME_A_STD PATIENT_FIRST_NAME_B_STD
LAST_NAME_A_STANDARDIZED PATIENT_FIRST_NAME_B_STD PATIENT_LAST_NAME_A_STD
LAST_NAME_B_STANDARDIZED PATIENT_LAST_NAME_A_STD PATIENT_LAST_NAME_B_STD
EMP_SSN_STANDARDIZED PATIENT_LAST_NAME_B_STD
EMP_FIRST_NAME_A_STANDARDIZED EMPLOYEE_FIRST_NAME_A_STD
EMP_FIRST_NAME_B_STANDARDIZED EMPLOYEE_FIRST_NAME_B_STD
EMP_LAST_NAME_A_STANDARDIZED EMPLOYEE_LAST_NAME_A_STD
EMP_LAST_NAME_B_STANDARDIZED EMPLOYEE_LAST_NAME_B_STD
PATIENT_SSN_STANDARDIZED
MPI Where each table name lists across with all of their column names under each table.
The query that I have so far is The following:
SELECT T1.TABLE_NAME, T1.COLUMN_NAME
FROM my_tab_cols t1, ( SELECT DISTINCT UPPER (SOURCE_TABLE) TABLE_NAME
FROM MPI_DEMOGRAPHICS_TEST
ORDER BY UPPER (SOURCE_TABLE)) tn
WHERE T1.TABLE_NAME = tn.TABLE_NAME
AND ( T1.column_name LIKE '%MPI%'
OR T1.column_name LIKE '%SSN%'
OR T1.column_name LIKE '%E%SSN%'
OR T1.column_name LIKE '%R%SSN%'
OR T1.column_name LIKE '%P%SSN%'
OR T1.column_name LIKE '%BIRTH%'
OR T1.column_name LIKE '%DOB%'
OR T1.column_name LIKE '%FIRST%NAME%'
OR T1.column_name LIKE '%LAST%NAME%'
OR T1.column_name LIKE '%CLIENT%NAME%'
OR T1.column_name LIKE '%SOURCE_TABLE%'
OR T1.column_name LIKE '%TABLE%')
ORDER BY T1.TABLE_NAME, t1.column_id; It just list everything straight down.
Where the MPI_DEMOGRAPHIES_TEST table feeds the relevant table names to the ALL_TAB_COLS table.
It can just be substituted with a list of the values, AAEADP1, AAMAET1, AAPMED1.
Is there a 'pivot' function in Oracle 11.1 that I can use to list these column names out sideways as opposed to what I did before?
Thanks,Hi,
Here's one way to get results like that using the Oracle 11 SELECT ... PIVOT feature:
WITH got_nums AS
SELECT column_name
, ROW_NUMBER () OVER ( PARTITION BY table_name
ORDER BY column_name
) AS r_num
, DENSE_RANK () OVER ( ORDER BY table_name) AS c_num
FROM my_tab_cols
WHERE column_name LIKE '%MPI%'
OR column_name LIKE '%SSN%'
-- OR column_name LIKE '%E%SSN%' -- Included in '%SSN% above
-- OR column_name LIKE '%R%SSN%' -- Included in '%SSN% above
-- OR column_name LIKE '%P%SSN%' -- Included in '%SSN% above
OR column_name LIKE '%BIRTH%'
OR column_name LIKE '%DOB%'
OR column_name LIKE '%FIRST%NAME%'
OR column_name LIKE '%LAST%NAME%'
OR column_name LIKE '%CLIENT%NAME%'
-- OR column_name LIKE '%SOURCE_TABLE%' -- Included in %TABLE% below
OR column_name LIKE '%TABLE%'
UNION
SELECT table_name AS colum_name
, 0 AS r_num
, DENSE_RANK () OVER ( ORDER BY table_name) AS c_num
FROM my_tab_cols
SELECT *
FROM got_nums
PIVOT ( MIN (column_name)
FOR c_num IN ( 1 AS table_1
, 2 AS table_2
, 3 AS table_3
ORDER BY r_num
;Output:

As with all pivots, you have to hard-code an upper bound to the number of pivoted columns. I used 3 above. You could use 4, or 5, or 45, but you must specify exactly how many columns to display.
If you say there will be 3 tables, and there actually are more than 3, then the query will still run, but all the tables after the first 3 will be ignored.
If you say there will be 3 tables, and there actually are fewer, then the query will still run, but you will have NULL columns at the end of each output row.
This sorts the output alphabetically by table_name and column_name. You can sort by anything you want by changing the analytic ORDER BY clauses. For example, if you are using all_tabl_columns and you want the columns to appear in order by column_id, then you would say:
, ROW_NUMBER () OVER ( PARTITION BY table_name
ORDER BY column_id -- instead of column_name

SQL Devloper Migration from SQL SerProcedurs created as Functions in Oracle
Hi All,
This is the first time I am using SQL Deveoper to migrate SQL Server database to Oracle.
I have SQL Developer 3 and I did migration from SQL Sever 2008 to Oracle 10g using online migration.
Everything was done perfectly, but there are some extra tables created in Oracle which are not present in SQL Server database.
And also I observed lot of programs which are stored procedures in SQL Server are converted as functions in Oracle.
Does someone knows how to fix this problem.
ThanksHi,
A SQL*Server stored procedure can be converted to an Oracle function depending on how it is written and what it is doing. In the documentation -
Oracle® SQL Developer
Supplementary Information for Microsoft SQL Server and
Sybase Adaptive Server Migrations
In Chapter 3 in the section -
3.4.2 Function
It says under Table 3-6 -
In Microsoft SQL Server or Sybase
Adaptive Server, you can convert a stored
procedure to a function in Oracle because
the stored procedure in Microsoft SQL
Server or Sybase Adaptive Server can
RETURN an integer value to the calling
routine using a RETURN statement. A
stored procedure returns a status value to
the calling routine even in the absence of
a RETURN statement. The returned status
is equal to ZERO if the procedure
execution is successful or NON-ZERO if
the procedure fails for some reason. The
RETURN statement can return only
integer values
And what tables do you see in oracle that are not there in SQL*Server ? Some tables are created as part of the migration as they are needed to have the same functionality as in SQL*Server.
Does your migrated Oracle database work in the same way as the SQL*Server database ? If not, then please give use specific examples and we can follow up.

Invoking SQL Server function from Oracle
Hi all,
My question involves Oracle and SQL Server. I have a function in SQL Server that returns the count of rows in a table in SQL Server itself. I
wish to invoke this function (in SQL Server) from Oracle. I have Transparent Gateway through which I usually connect to SQL Server to get the count. Is there a way in which I can execute the function (in SQL Server) from Oracle, something like below:

AlinaSounds like you have not included the xsu12.jar file in the server-side CLASSPATH.
This depends also on the xmlparserv2.jar and on the Oracle JDBC driver. Later versions
of XSU may also depend on the xdb.jar file, too. -

Arun M MWhat are you going to return the structure to? What I would normally use here if the code was going to be used by other PL/SQL would be a PL/SQL object type.
However, if PowerBuilder is still in the equation (you're moving the logic to PL/SQL but keeping PowerBuilder for the GUI ), then you'll have to return something else, because PowerBuilder doesn't understand PL/SQL object types. Perhaps passing a REF CURSOR as a OUT argument and populating it from the procedure. PowerBuilder could then retrieve the result of the procedure using a stored procedure based DataWindow. -
In order to use oracle.sql.* class, what do I need besides classesXX.zip? I have oracle 8.1.6 standard edition for NT/2000.
HouminI think you can post this question better in some j2ee related subforum (or the OC4J standalone forum), but looking at the error you get I would guess that you have some broken (or missing) jdbc driver.

Calling SQL Server Function from Oracle Database link
Hi ,
i have some data from a old SQL server i would i can access with a database link but i cant call function from my database link.
i would like to do something like
@SPAN_PROD = Database link
_EnerttObtApReelBassSys is a Table function from my SQL server
SELECT *
FROM "_EnerttObtApReelBassSys('20120504',4,1)"@SPAN_PROD
WHERE DateEffectiveDebut <= GetDate()
AND DateEffectiveFin > GetDate()
any help ?

I have a SP in SQL Server which will return a Result Set.
My requirement is to call that procedure in ORACLE using DB Link and insert that resultset(Data) in the temp table.First you need to setup Oracle to SQL Server connectivity. To do that you can either use HS - heterogeneous connectivity which comes for free or use Oracle Transparent Gateway which is not free. HS uses ODBC, so if your Oracle database in not on windows, you'll have to get ODBC SQL Server driver for Unix/Linux (e.g. from EasySoft). Since SQL Server selecting from table function syntax is different from Oracle's you will have to, if you use HS, to use DBMS_HS_PASSTHROUGH package. I never worked with Oracle Transparent Gateway to SQL Server, so I don't know if and how it supports selecting from SQL Server table function.

Pl/sql function body returning SQL query - Print function
Hello all,
I have pl/sql function body returning SQL query for my reports for my new project that I am developing. We dont have any BI tool or anything for APEX so we use Oracle reports to get the same reports to be printed in PDF format. I had been using SQL function for Reports all these days and grabbing the data using SQL query was easy in Oracle reports. But this time we had atleast 8 fields in search criteria and hence I thouhgt PL/sql function body returning SQL query could be something easy to handle that scenario. We have 11 such reports in our project. Now when we tried to use the same PL/sql function to oracle reports , I was told by one of our Oracle reports expert, that we have to write it into functions and use it in SQL query to get the Reports in Oracle reports. Is there any Easy way to convert the same Pl/SQL function or get a PDF format of the same report in APEX without going thru the much pains of rewriting the whole SQL Query.
thank you

Static class functions: PLS-00801: internal error [phd_get_defn:D_S_ED:LHS]

PLS-00801: internal error [phd_get_defn:D_S_ED:LHS]If the static class functions are removed from the constructor and applied instead inside the constructor body, it works without error.

Hai Friends ,
I want some help on java.sql.Types class .
What is the use of the above class ?
Some details about this class.Good Morning Yekesa
First of all i would like to thank U for looking into my problem.
I am using java.sql.Types.OTHER for
{"?=CALL(storedprocedurename.functionname(?))"}
registerOutParameter(1,javal.sql.Types.OTHER)
setString(2,"user")
here the
second parameter passes an argument to function name ( viz. username say "user")
and the function will return the ref cursor as follows:
// declaration in pl/sql procedure
begin
rc ref cursor
open rc for select * from ss_user where login_name="user";
return rc;
end
now the stored procedure has a return value (i.e. stored function) which it needs to register as
registerOutParameter(1,javal.sql.Types.OTHER)
and it finally results in the following errors :
Loading driver
Before conn stmt
After conn stmt
Calling Stored procedure
Stored procedure called
java.sql.SQLException: Invalid column type

at oracle.jdbc.driver.OracleCallableStatement.registerOutParameter(OracleCallableStatement.java:54)
at sptest.<init>(sptest.java:28)
at sptest.main(sptest.java:49)
T couldn't understand why it is saying Invalid Column Type because its working fine with both
java.sql.Types.INTEGER
and
java.sql.Types.VARCHAR
Pl help me at the earliest as i have wasted a lot of time on it.
pl mail me in detail at [email protected]
