Search for a record from Access Database, and populate records in Drop Down List, and View It

Hi,
I created a PDF form where I have open, next, previous buttons, and I'm able to connect to the access database, and it's working fine. Now, I want to be able to search by last name from the access database, and retrieve the results in a dropdown field, and then once i select the records in the drop downlist, i want to press a button to display the record. I have multiple records with the same last name. Please help, I searched the internet for hours, and can't find something similar. Your help is appreciated, and sample code is appreciated.

<%
int count = 0;
while (rs1.next()){ %>
<%if (count ==0)
{%>
<option value="<%=inputorthodon%>" selected >
<%=rs1.getString("ortho_name")%></option>
<%}
else{%>
<option value="<%=inputorthodon%>">
<%=rs1.getString("ortho_name")%></option>
<%}
++count;} %>
</select>
U may have to format this a bit. The idea is to use a count variable to put "selected" in only the first OPTION. After that, we don't have to.
Hope this helps.

Is it possible to import an Access database and forms

Is it possible to import an Access database and forms into apex

Yes and no.. Sorry.. The Access data tables and data can be imported into the database, through SQL Developer. The forms I don't believe will be ported over. What will be created through is a set of maintenance report and form sets for each table you convert over.
That is a good start to converting the database over, since you will probably want to re-do your Access style vba coding to use the available templates and pl/sql code..
Thank you,

TDMS database and treat its values as real time data.

Hi,
I'm newbie in using labview. Actually I wanna import data from TDMS database and treat it as real time data. Although I have done the first part which is importing the data inside the program by reading TDMS and selecting channels and groups, I couldn't find way for second part which is treating data as real time one. I tried Build Waveform, but it didnt work. Would you please help me to solve this problem ? I appreciate your helps.

reza_amin,
I don't understand your word "build waveform". If you write waveform data to a tdms file, you will read waveform data directly from the tdms file.
If you are using LabVIEW 2012 (download from http://www.ni.com/trylabview), you could find a tdms example VI in "C:\Program Files\National Instruments\LabVIEW 2012\examples\file\plat-tdms.llb\TDMS - Concurrent File Access.vi". This example VI demonstrates how to write Sine Waveform into a tdms file and read the Sine Waveform from the tdms file.
Hope this helps and enjoy your LabVIEW journey. :-)
Best Regards,
Bo Xie

Storing a JAR file in a database and then accessing it

Is it possible to store a JAR file in a database and then access it like a normal jar that is on your classpath?
I'm sure this is not possible but can you specify an XML schema in an XML document where the XML schema file lives in the jar but the xml file doesn't?
Cheers.

Process of sending PI Sheet to Database and what is its utility

What is the process of sending PI Sheet to Database and what is its utility?

Hi,
Control Recipe execution
T/Code: CO53 (Control Recipe Monitor)
You will get control recipe generated for this process order. Select the control recipe and click on u201CSendu201D.
You will see that status will be changed to u201CSentu201D after refreshing the screen.
PI Sheet maintenance
Now, you can view the PI Sheet generated using T/Code: CO60.
Press execute button (F8) you will come to see the PI Sheet generated screen.
Now in the first phase of PI Sheet enter your u201CUseridu201D for digital signature.
Enter password, so that user (PIUSER) can authorize the process.
After entering all the values you can save the PI Sheet and can set it to u201CTechnically Completeu201D as below.
After Tech completing the PI sheet, the order status get changed from CRCR (Control Recipe Created) to CRFI (Control Recipe Finished).
Process Messages execution
As you process/execute the PI sheet, resp. process messages get generated. You can view the generated messages in Process Message Monitor (CO54).
Now you can see the different process messages generated,
Now select all process messages and click on Send tab to send them to the control recipe destination. Refresh the screen so that you will get the status of the process messages as u201CSentu201D.
After sending these messages to the respective destination, the system posts the goods movements (i.e. GI, GR) in background and update the statistics. You can process the process messages after completion of each phase or after the completion of the PI sheet.
Hope you understand it.

Database and ejb access in Input Processor, custom Validator

Hi guys,
I know the Portal docs recommend that database and ejb calls should be done in
a Pipeline Component. Are transactions the only concern?
I'd like to validate two fields. This can be easily accomplished by a an ejb
method call that returns a boolean for one, and by running a simple select statement
for the other. Are there any risks to creating custom validator classes to do
this?
Thanks

David,
Here are the characterstics of Pipelines and IPs:
Inputprocessors:
- Web App scope (classloaded by webapp classloader)
- simple java class
Pipelines/Pipeline Components:
- Enterprise App scope (available to all webapps)
- java class or EJB
- can be transactional (can even rollback PipelineSession)
- Pipelines executed from within the EJB container
There is nothing illegal about putting EJB calls and JDBC calls into an Inputprocessor.
For simple validation, this is probably okay. However, when doing heavy business
logic, having the Pipeline manage a single transaction for your PCs is wonderful.

Lost Tomcat, its database and all JSP and HTML files

I have mistakably uninstalled Tomcat from my machine, it removed the data I stored in the root including HTML and JSP files, I am using windows XP, Is there any way I can recover htem back, atlest the database and the JSP files? please Help

Also a good example of why you should develop apps in a separate directory structure and then deploy the WAR file to Tomcat.
You didn't have all your source code under Tomcat, did you?
You weren't using a source control system like CVS?
Oh, my. ;)
You will from now on, I'll bet.

How to implement Oracle user/role security with Access front end?

Hi,
We have successfully migrated our Access database tables to Oracle 10g using SQL developer. We've recreated all the users and roles(i.e., access groups) in Oracle and granted rights to tables.
In the Access front end database, in the Database window we have saved linked Oracle tables which replaced the Access tables. The forms, reports, queries run fine with the linked Oracle tables. All the linked table use one ODBC DSN to the Oracle database with the same Oracle user id.
We need to be able to authenticate users into the Oracle database and RE-link the tables based on their own unique user id. By during so we can allow users to use the Oracle standard user id/role and system privileges to control select, update, ect. rights to the database.
I've been able to use the VB code within Access to logon into the database with a unique id, but I have not been able to find out how to RE-link the tables to the unique user id using VB. There should be some way to relink tables dynamically, based on users login into the Access front end.
I don't know a great deal about Access projects, but I do know with SQL server allows login into your Access project and link tables dynamically.
Can someone give me some assistance or point me in the right direction?
Thanks in advance,
Larry

We had one of our programmers here come up with a VB code solution for re-linking table within Access. However the relinking takes 3-4 minutes for 100+ tables.
In an effort to help you understand the situation better, I will attempt to elaborate on the problem:
We have an Access 2003 application which currently has a front end using Access(forms, reports, queries, & VB code) and a MS Access 2003 backend.
We have migrated the backend tables to Oracle. However, we still have a need to maintain the front end in Access, since we have over 60 forms, 40 reports, 200+ queries in Access. Its easy to understand, we have a significant investment in the front end(Obviously, the plan is to migrate the front end also at some future date).
In order to utilized the existing front end, we have to validate and modify the current front end connections to the new Oracle backend. One of the features of Access is that you can "link" tables and save the link for runtime. Each Access table can have its own link which is a separate ODBC/JET connection. As such, each separate link has its own userid/database information.
The other issue with using the Access front-end is that Access utilizes a workgroup file to implement user and group security. The workgroup file contains all the users and which groups the users belong to in Access. Then within Access, you allow users access to object(tables, queries, ect) by their userid and or group. When users open an Access database with Access security enabled, they are required to log into Access. The login is authenticated by the workgroup file. Once, logged into Access, users have rights to Access objects based on their rights granted to their userid and groups they belong. The problem here is that when you remove the linked Access tables and replace them with linked Oracle tables, Access has knowledge about Oracle table rights granted to users; nor would you expect it to.
The dilema is the disconnect between Access and the fact Oracle utilizes a similar but much more sophisticated security model. It creates users and roles(which are similar to Access groups), and again this is independent of Access security.
Our solution was to still use the Access workgroup file security along with the Oracle security model. By using the Access userid and then creating a similar Oracle userid with similar table rights granted in Access, you could apply security within Access and also with the Oracle database.
For example, a user BOB logs into Access via the workgroup file, using VB code, Access then establishes a Oracle connection logining into Oracle using the same unique userid BOB into Oracle.
After connecting and validating user BOB into Oracle, then the Access tables are relinked to Oracle using the user BOB userid and table rights.
This Oracle userid has been granted table rights specific for this userid.This allows the user BOB to use the Access application and still be authenticated into the Oracle database.
The problem with this solution is that the relinking of the saved Access tables takes 3-7 minutes for about 100+ tables. This is not acceptable for users each time they log into the application.
Our current alternative is to use one Oracle userid to login each user, and use Access form restrictions/security to allow/prevent users from updating/viewing data. Obviously, this is not the optimal solution in respect to security, but it at least allows us to control access to the data(via the forms) by using one logon required for each user, and quick startup time for the application.
I understand SQL server does a better job in integration, but we use Oracle which is what I am trying to work with.

Regarding Logical database and select statement..

Hi
Experts.
i would like to know the diff b/w logical data base & select statement while using report.
wt is the use of logical databases in R/3. is there   any   advantage used in the reports.
Thanks & Regards..
Spandana.

Dear Spandana,
Go through the below description of LDB. I hope you wil get a fair amount of idea.
SAP comes loaded with all the extras. Among the extras that are most helpful to IT managers are all the access routines needed to pull any business object that managers can think of out of SAP databases. However, SAP has not thought of everything where your particular applications are concerned. SAP organizes its standard database tables to service business units based on conventional business applications. Itu2019s likely your business requires something new, perhaps even something exotic. In that case, you will need to create a new database, using information from different places. Basically, you need a logical database. You need to create a virtual business data object repository consisting of a new kind of record or table that suits your purposes. In addition, the repository should be composed of information that is actually stored in a number of different locations, none of them necessarily logically associated with one another. Letu2019s take a closer look at creating logical databases.
A case for a logical database
Suppose my company manufactures widgets of the most obscure variety, and they are components of other widgets. I sell my widgets as raw material for the more sophisticated widgets built by others, but in some cases I actually partner with other manufacturers in creating yet another class of widget. Now, in my world, I consequently have customers who are also partners. I sell to them and I partner with them in manufacturing and distribution. Also, I need an application that uses both of these dual-use relationships.
Essentially, I have a customer database and a partner database. Neither contains records that are structured to contain the identifying particulars of the other. Thus, I need a hybrid database that gives me tables detailing these hybrid relationships. What can I do? I can go the long way around and write a new database, pulling information from both and creating new objects with a customized program that I write by hand. However, this process is cumbersome and contains maintenance issues. On the other hand, I can use SAPu2019s logical database facility, create my logical database in a couple of minutes, and have no maintenance issues at all.
Logical database structures
There are three defining entities in an SAP logical database. You must be clear on all three in order to create and use one.
u2022     Table structure: Your logical database includes data from specified tables in SAP. There is a hierarchy among these tables defined by their foreign keys (all known to SAP), and you are going to define a customized relationship between select tables. This structure is unique and must be defined and saved.
u2022     Data selection: You may not want or need every item in the referenced tables that contributes to your customized database. There is a selection screen that permits you to pick and choose.
u2022     Database access programming: Once youu2019ve defined your logical database, SAP will generate the access subroutines needed to pull the data in the way you want it pulled.
Creating your own logical database
ABAP/4 (Advanced Business Application Programming language, version 4) is the language created by SAP for implementation and customization of its R/3 system. ABAP/4 comes loaded with many predefined logical databases that can construct and table just about any conventional business objects you might need in any canned SAP application. However, you can also create your own logical databases to construct any custom objects you care to define, as your application requires in ABAP/4. Hereu2019s a step-by-step guide:
1.     Call up transaction SLDB (or transaction SE36). The path you want is Tools | ABAP Workbench | Development | Programming Environment | Logical Databases. This screen is called Logical Database Builder.
2.     Enter an appropriate name in the logical database name field. You have three options on this screen: Create, Display, and Change. Choose Create.
3.     Youu2019ll be prompted for a short text description of your new logical database. Enter one. Youu2019ll then be prompted to specify a development class.
4.     Now comes the fun part! You must specify a root node, or a parent table, as the basis of your logical database structure. You can now place subsequent tables under the root table as needed to assemble the data object you want. You can access this tree from this point forward, to add additional tables, by selecting that root node and following the path Edit | Node | Create. Once youu2019ve saved the structure you define in this step, the system will generate the programming necessary to access your logical database. The best part is you donu2019t have to write a single line of code.
Watch out!
The use of very large tables will degrade the performance of a logical database, so be aware of that trade-off. Remember that some tables in SAP are very complex, so they will be problematic in any user-defined logical database.
Declaring a logical database
Hereu2019s another surprising feature of logical databases: You do not assign them in your ABAP/4 Code. Instead, the system requires that you specify logical databases as attributes. So when you are creating a report, have your logical database identifier (the name you gave it) on hand when you are defining its attributes on the Program Attributes screen. The Attributes section of the screen (the lower half) will include a Logical database field, where you can declare your logical database.
Logical databases for increasing efficiency
Why else would you want to create a logical database? Consider that the logical databases already available to you begin with a root node and proceed downward from there. If the data object you wish to construct consists of items that are all below the root node, you can use an existing logical database program to extract the data, then trim away what you donu2019t want using SELECT statementsu2014or you can increase the speed of the logical database program considerably by redefining the logical database for your object and starting with a table down in the chain. Either way, youu2019ll eliminate a great deal of overhead.

duplicate here SQL error in the database when accessing a table.
Do not post the same question in more than on forum.

DBIF_RSQL_SQL_ERROR with SQL error in the database when accessing a table.

dear all,
i have done a system copy from production server into quality server. quality was scrapped and freshly installed with SAP then used the DB flush method to carry out the system copy. i had to change the DBS_ORA_SCHEMA in environment variables to SAP<SOURCE SID> from SAPSR3. the sap version is ECC6.0,DB is ORACLE10.2 on WIN NT.
after MMC opened, i get "SQL error in the database when accessing a table" error is coming. in SM21, I am getting "Transaction Canceled 00 671 ( DBIF_RSQL_SQL_ERROR 20081018130339sibqty_QTY_00 SAPSYS 000 )
Database error 8103 at SEL access to table TBTCO

please find the st22 DUMP:
ow to correct the error |
Database error text........: "ORA-08103: object no longer exists"
Internal call code.........: "[RSQL/READ/TBTCO ]"
Please check the entries in the system log (Transaction SM21).
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"DBIF_RSQL_SQL_ERROR" "CX_SY_OPEN_SQL_DB"
"SAPMSSY2" or "SAPMSSY2"
"INITIATE_JOB_START"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
To save the description, choose "System->List->Save->Local File
(Unconverted)".
2. Corresponding system log
Display the system log by calling transaction SM21.
Restrict the time interval to 10 minutes before and five minutes
after the short dump. Then choose "System->List->Save->Local File
(Unconverted)".
3. If the problem occurs in a problem of your own or a modified SAP
program: The source code of the program
In the editor, choose "Utilities->More
Utilities->Upload/Download->Download".
4. Details about the conditions under which the error occurred or which
actions and input led to the error.
The exception must either be prevented, caught within proedure
"INITIATE_JOB_START" "(FORM)", or its possible occurrence must be declared in
the
RAISING clause of the procedure.

please do me this favor if you know to avoid this problem..
thanks a lot..

Hello Anuj,
This is because the COUNT(*) is returning a value which is longer than the INT4 data type it is expecting. If you restrict the selection by introducing a WHERE clause, then you won't get the dump:
DATA: dyn_from TYPE string,
 dyn_where TYPE string,
 gx_sql_err TYPE REF TO cx_sy_open_sql_error,
 gv_text TYPE string.
dyn_from = `DD01L INNER JOIN DD02L ON DD02L~AS4LOCAL = DD01L~AS4LOCAL AND DD02L~AS4VERS = DD01L~AS4VERS`.
dyn_where = `DOMNAME LIKE 'Z%'`.
TRY .
 SELECT COUNT(*) FROM (dyn_from) WHERE (dyn_where).
 WRITE: / sy-dbcnt NO-GROUPING.
CATCH: cx_sy_open_sql_db INTO gx_sql_err,
 cx_sy_dynamic_osql_semantics INTO gx_sql_err,
 cx_sy_dynamic_osql_syntax INTO gx_sql_err.
ENDTRY.
IF gx_sql_err IS BOUND.
gv_text = gx_sql_err->get_text( ).
WRITE: / gv_text.
ENDIF.
