How execute pl/sql command from Oracle ADF Business Components

can't find examples for how execute pl/sql command from Oracle ADF Business Components and how call pl/sql package procedure from ADF Business Components.
insert,update,delete rows in view object instance cache is good but if i must do some complex operations while insert,update,delete rows..it's more better for me to call
pl/sql procedure from oracle db.Am i wrong ????

Roman,
this should be similar to how it worked in JDeveloper 9.0.3. hava a look at <JDev903 Home>\BC4J\samples\StoredProc for a code example.

How to use lengthy query in a "SQL Command from Variable"

My oracle SQL Query length is more than 14000 characters, so how can i use this for "SQL command from variable".
Sarvan

Either create a view or a table valued UDF. Using stored procedure in OLEDB source has some gotchas it will not pick up metadata information by default due to late binding.

Executing a sql command from a menu item

I am working on a forms migration from 4.5 to 10g.
On 4.5, if I execute a sql using a sqlplus -s command, from a menu item, a window is opened showing the execution messages, if there were errors and it's details.
It doens´t happen on 10g anymore. Is there any chance I can keep on 10g this functionality that used to work on 4.5 ??
The procedure I use to execute the sql is:
Menu item code:
plus('sql_ name',null);
Procedure:
procedure plus(
program in VARCHAR2, /* sql name*/
parameters in VARCHAR2 /* aditional parameters */
) is
V_USERNAME varchar2(100);
V_PASSWORD varchar2(100);
V_DATABASE varchar2(100);
str varchar2(300);
begin
V_USERNAME := GET_APPLICATION_PROPERTY(USERNAME);
V_PASSWORD := GET_APPLICATION_PROPERTY(PASSWORD);
V_DATABASE := GET_APPLICATION_PROPERTY(CONNECT_STRING);
str := V_USERNAME||'/'||V_PASSWORD||'@'||V_DATABASE;
HOST ('sqlplus -s '||''''||str||''''||' @$PATH/'||program||' '||parameters);
end;
Tks a lot,

Hello,
With C/S versions, the Host() command execute on the machine that runs the Forms runtime, that is the client machine.
With Web versions, Host() is also executed on the machine that runs the Forms runtime, that, this time is the application Server.
Use the Client_Host() Webutil equivalent.

Running sql commands from a .sql file

Hello , I have this problem. How do i execute sql commands found in a .sql file with jdbc. My RDBMS is mysql.

You will have to open and parse the .sql file, connect to the database, and execute the statements. You can't simply tell JDBC to run your .sql file.
Depending on the complexity of your .sql file this is easy or hard. If its a bunch of e.g. updates or deletes or something you may be able to get away with running it as a block. In Oracle for example, you can put "begin" and "end;" around a bunch of statements and run it all together. In that case your program would open the SQL file, read the text, put it inside a "begin" and "end;", and run it as a single SQL statement.
If its a bunch of statements that must be run independently then you'll have to programatically split them up to run one at a time. If its a select and you want to e.g. print results to the screen, well, then it gets tougher...

How to issue iCommand Commands in code?

I understand how to bind iCommand commands to UI elements.
I would like to know how to issue Commands in C# code.
I need to do this so that I can issue commands in the Click event code behind for UI elements that don't support commands, such as App Bar Buttons.
Any examples would be greatly appreciated.
Thanks!

Your example would work, except that I don't have a button on my page to reference. I want the code behind for an AppBarButton, which does not support the "Command" parameter, to be able to raise/issue/fire (proper term?) a command.
I could put a hidden button on the page and then reference it's Command, but that just seems like a really ugly way to do it.
Any suggestions?
Hi Pfredd,
>>I want the code behind for an AppBarButton, which does not support the "Command" parameter, to be able to raise/issue/fire (proper term?) a command.
Generally, this will break MVVM pattern if you want to invoke Command from code behind, I would suggest you customizing AppBarButton like this and set Command binding:
<AppBarButton x:Name="WeekButton" Label="SomeText" >
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
<Button Command="{Binding OkCommand}" >
</Button>
</StackPanel>
</AppBarButton>

OS command from PL/SQL code

Is there any way of running on OS (Operating System) command from SQL or PL/SQL. i.e. calling an executable from a trigger.

Is there any way of running on OS (Operating System) command from >SQL or PL/SQL. i.e. calling an executable from a trigger. Ashis,
Here's an example of a simple piece of Java you can create using SQL*Plus:
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "RuntimeExample" AS public class RuntimeExample {
public static String runNotepad() {
String returnValue = null;
Runtime r = Runtime.getRuntime();
try {
     Process p = r.exec("notepad.exe");
     returnValue = p.toString();
     } catch (Exception e) {
          System.out.println("Exception calling Runtime.exec()->" + e);
     /* You can get creative here and
     1) Use p.waitFor() to block while the process is running,
     2) Send the command to be executed as a parameter to the method, etc. */
     return returnValue;
CREATE OR REPLACE FUNCTION runNotepad RETURN VARCHAR2 IS
LANGUAGE JAVA NAME 'RuntimeExample.runNotepad() return java.lang.String';
DECLARE
my_varchar2 VARCHAR2(64);
BEGIN
my_varchar2 := runnotepad;
DBMS_OUTPUT.PUT_LINE(my_varchar2);
END;
Hope this helps,

Debug Java in the Oracle Database

Read from sql task and send to data flow task - [OLE DB Source [1]] Error: A rowset based on the SQL command was not returned by the OLE DB provider.

I have created a execut sql task -
In that, i have a created a 'empidvar' variable of string type and put sqlstatement = 'select distinct empid from emp'
Resultset=resultname=0 and variablename=empidvar
I have added data flow task of ole db type and I put this sql statement under sql command - exec emp_sp @empidvar=?
I am getting an error.
[OLE DB Source [1]] Error: A rowset based on the SQL command was not returned by the OLE DB provider.
[SSIS.Pipeline] Error: component "OLE DB Source" (1) failed the pre-execute phase and returned error code 0xC02092B4.

shouldnt setting be Result
Set=Full Resultset as your query returns a resultset? also i think variable to be mapped should be of object type.
Then for data flow task also you need to put it inside a ForEachLoop based on ADO.NET recordset and map your earlier variable inside it so as to iterate for every value the sql task returns.
Also if using SP in oledb source make sure you read this

SQL Command conversion in abap code

Hi,
I want to implement the UNION, INTERSECT and MINUS SQL commands in abap code. Please give me the appropriate solutions asap.
For Example:
select field1, field2, . field_n
from tables
<b>UNION</b>
select field1, field2, . field_n
from tables;
select field1, field2, . field_n
from tables
<b>MINUS</b>
select field1, field2, . field_n
from tables;
select field1, field2, . field_n
from tables
<b>INTERSECT</b>
select field1, field2, . field_n
from tables;
Thanks,
Ravi

Hi Ravi
Check out this procedure...
DATA: FRANKFURT(4) TYPE X,
      FRISCO(4)    TYPE X,
      INTERSECT(4) TYPE X,
      UNION(4)     TYPE X,
      BIT          TYPE I.
DATA: CARRID TYPE SPFLI-CARRID,
      CARRIER LIKE SORTED TABLE OF CARRID
                          WITH UNIQUE KEY TABLE LINE.
DATA WA TYPE SPFLI.
SELECT CARRID FROM SCARR INTO TABLE CARRIER.
SELECT CARRID CITYFROM FROM SPFLI
                       INTO CORRESPONDING FIELDS OF WA.
WRITE: / WA-CARRID, WA-CITYFROM.
READ TABLE CARRIER FROM WA-CARRID TRANSPORTING NO FIELDS.
CASE WA-CITYFROM.
    WHEN 'FRANKFURT'.
      SET BIT SY-TABIX OF FRANKFURT.
    WHEN 'SAN FRANCISCO'.
      SET BIT SY-TABIX OF FRISCO.
ENDCASE.
ENDSELECT.
INTERSECT = FRANKFURT BIT-AND FRISCO.
UNION     = FRANKFURT BIT-OR FRISCO.
SKIP.
WRITE 'Airlines flying from Frankfurt and San Francisco:'.
DO 32 TIMES.
GET BIT SY-INDEX OF INTERSECT INTO BIT.
    IF BIT = 1.
      READ TABLE CARRIER INDEX SY-INDEX INTO CARRID.
      WRITE CARRID.
    ENDIF.
ENDDO.
SKIP.
WRITE 'Airlines flying from Frankfurt or San Francisco:'.
DO 32 TIMES.
GET BIT SY-INDEX OF UNION INTO BIT.
    IF BIT = 1.
      READ TABLE CARRIER INDEX SY-INDEX INTO CARRID.
      WRITE CARRID.
    ENDIF.
ENDDO.
This produces the following output list:
The program uses four hexadecimal fields with length 4 - FRANKFURT, FRISCO, INTERSECT, and UNION. Each of these fields can represent a set of up to 32 elements. The basic set is the set of all airlines from database table SCARR. Each bit of the corresponding bit sequences representes one airline. To provide an index, the external index table CARRIER is created and filled with the airline codes from table SCARR. It is then possible to identify an airline using the internal index of table CARRIER.
In the SELECT loop for database table SPFLI, the corresponding bit for the airline is set either in the FRANKFURT field or the FRISCO field, depending on the departure city. The line number SY-TABIX is determined using a READ statement in which no fields are transported.
The intersection and union of FRANKFURT and FRISCO are constructed using the bit operations BIT-AND and BIT-OR.
The bits in INTERSECT and UNION are read one by one and evaluated in two DO loops. For each position in the fields with the value 1, a READ statement retrieves the airline code from the table CARRIER.
Comparing Bit Sequences
Use the following three operators to compare the bit sequence of the first operand with that of the second:
<operator>
Meaning
O
bits are one
Z
bits are zero
M
bits are mixed
The second operand must have type X. The comparison takes place over the length of the second operand. The first operand is not converted to type X.
The function of the operators is as follows:
O (bits are one)
The logical expression
<f> O <hex>
is true if the bit positions that are 1 in <hex>, are also 1 in <f>. In terms of set operations with bit sequences, this comparison is the same as finding out whether the set represented by <hex> is a subset of that represented by <f>.
Z (bits are zero)
The logical expression
<f> Z <hex>
is true if the bit positions that are 1 in <hex>, are 0 in <f>.
M (bits are mixed)
The logical expression
<f> M <hex>
is true if from the bit positions that are 1 in <hex>, at least one is 1 and one is 0 in <f>.
Caution: The following programs are no longer supported in Unicode systems:
REPORT demo_log_expr_bits .
DATA: text(1) TYPE c VALUE 'C',
      hex(1) TYPE x,
      i TYPE i.
hex = 0.
DO 256 TIMES.
i = hex.
IF text O hex.
    WRITE: / hex, i.
ENDIF.
hex = hex + 1.
ENDDO.
The output is as follows:
00          0
01          1
02          2
03          3
40         64
41         65
42         66
43         67
Here, the bit structure of the character 'C' is compared to all hexadecimal numbers HEX between '00' and 'FF' (255 in the decimal system), using the operator O. The decimal value of HEX is determined by using the automatic type conversion during the assignment of HEX to I. If the comparison is true, the hexadecimal number and its decimal value are displayed on the screen. The following table shows the bit sequences of the numbers:

Database Server - SQL Access: Cannot connect from code but from SSMS

Hi,
I am using following connection string in my asp.net web.config:
[Less than symbol] add name="FMMConnectionString" connectionString="Data Source=xxxxxxxxx,1234;Initial Catalog=Test1Db;User Id=Rajeev;Password=xxxxxxxxxxxxx;" providerName="System.Data.SqlClient" [Slash][Greater than symbol]
The database is on remote database server. The sql user/ developer 'Rajeev' is deliberately given restricted permissions (to protect our schema) using following sql commands:
GRANT ALTER,EXECUTE, SELECT,INSERT,UPDATE,DELETE ON SCHEMA ::dbo TO Rajeev
DENY VIEW DEFINITION ON SCHEMA::dbo TO Rajeev;
GRANT CREATE PROCEDURE TO Rajeev;
GRANT CREATE FUNCTION TO Rajeev;
DENY ALTER ON SCHEMA::dbo TO Rajeev; -- To disallow Rajeev to create objects on dbo schema but only create in Rajeev schema while still being able to select, insert, execute on dbo schema.
The above connection string works perfectly fine when used from Visual Studio> Server Explorer. I am able to execute following sql queries without issues. Same is true when using SQL Server Management Studio using Rajeev credentials.
select top 100 * from XYZEmployees
execute usp_GetMMBSchemeDetails '1'
The error I get in web page is following:
The stored procedure 'usp_GetMMBSchemeDetails' doesn't exist.
When I ran code using breakpoints to see what is happening, I see that when connection object is being instantiated, the connection state is being closed with following error:
at System.Data.SqlClient.SqlConnection.GetOpenConnection()
at System.Data.SqlClient.SqlConnection.get_ServerVersion()
I turned off my firewall to see if it was blocking but it did not help. I tried using Visual Studio 2012 as well as Visual Studio 2013 but same issue showed up.
Kindly let me know why I am able to execute sql queries from SSMS and Visual Studio's Server Explorer but not from application code. Is there something that needs to be enabled on remote database server so that the queries can run from code? I like to create
more users like Rajeev with restricted permissions to develop my application. So kindly provide a solution if you know.
Thanks,
Pullet

Thanks Everyone for your insights :)
RSingh, Your approach works when using SSMS, not when called from application code (example: asp.net code-behind page calling a stored proc using connection object).
My requirement is, I only wanted developer to do front end programming without having the ability to look at backend sql objects definitions. He/she can call the sql objects in the program as needed.
I am able to finally solve this requirement by following approach. Hope it helps others.
1. Right-click Rajeev user in Database> Security>Users and unselect 'dbowner' from 'General' tab> 'Database Role Membership' section even though Default Schema shows up as Rajeev schema. Now, this user can't do anything on dbo schema of database
(as well as in any other user's schema in this database).
2. Ran above commands but excluded following command which was identified as root-cause.
DENY VIEW DEFINITION ON SCHEMA::dbo TO Rajeev;
3. Now ran a script that denies 'view definition' of dbo schema's tables. It loops through all tables and denies 'view definition' on each table. Adapted the script of http://blog.extreme-advice.com/2013/01/23/grant-view-defination-permission-to-all-stored-procedures-in-sql-server/.
Now, the user Rajeev can execute dbo schema objects both from SSMS as well as from application code.
4. DENY EXECUTE, SELECT ON SCHEMA::INFORMATION_SCHEMA TO Rajeev; -- Restricts Rajeev from executing INFORMATION_SCHEMA objects seen in SSMS.
However one remaining open item is, I could not hide the system objects (which are part of sys schema) in SSMS. Ideally, I do not want Rajeev to execute the 'system views', 'system stored procedures', etc. When I execute same command (below command), it
runs without errors but does not apply this restriction.
DENY EXECUTE, SELECT ON SCHEMA::sys TO Rajeev;
If you know the reason why it is happening like this, please kindly share.
Cheers,
Pullet

Read data from SharePoint using ABAP sql command

We need to read data from a SharePoint site and update the sap object services with the information. There is a lot of information on how to put data into Sharepoint from SAP, but we need to get data from SharePoint and put it into SAP. Is it possible to retrieve data from SharePoint using sql command in ABAP program? If it is possible, what do we need to do to have SAP recognize where to get the SharePoint data?
Richard Newman

Hi Newman,
You can use native sql in your abap code to read data from SharePoint's database. But I would suggest you to generate a SharePoint webservice which can provide you the neccessary data so that you can consume this webservice in ABAP
(Will be quite faster than native sql).

Calling SQL Loader using HOST command from Developer Forms 4.5

I want to execute a set of code from D2K Forms 4.5 which has interfface with Client - OS ( In my case Windows NT/XP). I want to execute SQL Loader from Forms using Host Command and then after completion of that process, I want to do next transcations ( depending upond success of HOST/SQL Loader).
How to achive this?
I tried writing code like this ...
l_vc_command := 'sqlldr73'
                    ||' USERID='||l_vc_username||'/'||l_vc_password||'@'||l_vc_connect_string
                    ||' CONTROL='||l_vc_filepath||'Upload.ctl'
                    ||' DATA='||LTRIM(RTRIM(l_vc_fileloc))
                    ||' LOG='||l_vc_filepath|| l_vc_log_file || '_' || l_dt_sysdate_str ||'.log'
                    ||' BAD='||l_vc_filepath|| l_vc_bad_file || '_' || l_dt_sysdate_str ||'.bad'
                    ||' DISCARD='||l_vc_filepath|| l_vc_discard_file || '_' || l_dt_sysdate_str ||'.dsc';
HOST(l_vc_command,NO_PROMPT);
After this command i want to do some other code execution. so even if it fails or success, next code is executed. How to control this?
Please help..

Forms6i running on W2000, Rdbms 8.1.7
in Forms I added a button TEST,
Trigger when-button-pressed : host('test.bat') ;
in directory .......\frm I added file test.bat :
REM ===============
cd /d C:\........\ldr
pause
sqlldr parfile=test.par
pause
type test.log
pause
exit
REM ================
now, pressing TEST button opens DOS window, telling me what's going on, running sqlldr, finally going back to forms
Are you using NO_PROMPT or NO_SCREEN option of HOST command ?
Had a look at Forms 4.5 manuals, there is no mentioning of (a)synchronously operation in connection with HOST command.

UTL_HTTP, different error codes: APEX SQL Commands vs. Oracle SQL Developer

Hi, omniscient all!
I have a code sample where I try to request some URL from an inactive server:
declare
l_text varchar2(32000);
begin
l_text := utl_http.request('http://inactive.url:7777');
exception
when others then
    declare
      l_errcode number := utl_http.get_detailed_sqlcode;
    begin
      dbms_output.put_line(l_errcode);
      dbms_output.put_line(sqlerrm(l_errcode));
    end;
end;
/When I run it in Oracle SQL Developer it shows:
anonymous block completed
-12541
ORA-12541: TNS:no listenerWhen I run it in the APEX 4.0 SQL Commands window it shows:
-29263
ORA-29263: HTTP protocol error
Statement processed.The question is: why?
In real world, I need to make a HTTP POST request (no problem) and catch some exceptions. But instead of the usual ORA-12541 error APEX throws an ORA-29261 one.

Any thoughts?

Xcopy Command From Sql

Dear Guru's,
I have Script of my all the procedure.

Writing any kind of Oracle application using scripts, is questionable ito design, robustness, flexibility, security and so on.
Wanting to use console commands from a SQL cursor? That sounds even more broken and wrong. If you want to do o/s calls, it should be done carefully and securely from PL/SQL code.
And PL/SQL code should be inside the database - not outside in some script.
As for copying files. Realise that SQL and PL/SQL code executes on the server inside an Oracle server process. This does not have access to your client's file system and directories.
