Verification Of Details Using SQL
Hi,
Within a servlet I wish to verify a users input details, similar to a login, but not quiet!
When a user enters details (text, double) I need to verify these are in the database and correct before allowing them to proceed!
I've tried doing it the same as my login, but its giving me weird errors and plus I think im doing other unecessary stuff!!
So am just wondering if anyone can help me?
if( TransferVerify.VerifyUser( transDetails[0], transDetails[1] ) == true )
public boolean VerifyUser(String acname, String acbalance){
System.out.println(acname);
System.out.println(acbalance);
SQL = "SELECT * FROM actable WHERE acname = '" + acname + "'";
SQL += "AND acbalance = '" + acbalance + "'";
boolean exists = false;All I want to do is a simple
if (userdetails == correct )
do something
else
do something else
}Any help appreciated,
Aidan.
Um, define "weird errors."

Thanks AdvanceHi,
you can use BREAK ON DEPTNO in SQL*Plus or use LAG.

Wrote file afiedt.buf
1 select nullif(department_id

Is there any way to find the connection details using sqlplus once a connection is made to the database. I would like to see the information similar to what I get while using the tnsping .
Hello Mate
If you can connect as a system , check the V$instance command.
or type show user in sqlplus

Problem occured when create a tree table for master-detail view objects using SQL queries?
I am programming a tree table for master-detail view objects using SQL queries and these 2 view objects are not simple singel tables queries, and 2 complex SQL are prepared for master and view objects. see below:

3. I create a view link to create master-detail relationship for these 2 view objects.
masterview.SourceBlock (1)->detailview.SourceBlock (*).
4. I create a tree table using these 2 view objects with master-detail relationship.
When I set default value for variable bindings of these 2 view objects and the matching records exist, tree table can work well. I can expand the master row to display detail row in UI.
But I need to pass in dymamic parameter value for variable bindings of these 2 view objects, tree table cannnot work again. when I expand the master row and no detail row are displayed in UI.
I am sure that I pass in correct parameter value for master/detail view objects and matching records exist.
Managed Bean:
DCIteratorBinding dc = (DCIteratorBinding)evaluteEL("#{bindings.MasterView1Iterator}");
ViewObject vo = dc.getViewObject();
System.out.println("Before MasterView1Iterator vo.getEstimatedRowCount()="+ vo.getEstimatedRowCount());
System.out.println("Before MasterView1Iterator ShiftModeCode="+ vo.ensureVariableManager().getVariableValue("ShiftModeCode"));
vo.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
vo.ensureVariableManager().setVariableValue("DateTo", dateTo);
vo.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
vo.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
vo.executeQuery();
System.out.println("MasterView1Iterator vo.getEstimatedRowCount()="+ vo.getEstimatedRowCount());
DCIteratorBinding dc1 = (DCIteratorBinding)evaluteEL("#{bindings.DetailView1Iterator}");
ViewObject vo1 = dc1.getViewObject();
System.out.println("Before DetailView1Iterator vo1.getEstimatedRowCount()="+ vo1.getEstimatedRowCount());
System.out.println("Before DetailView1Iterator ShiftModeCode="+ vo1.ensureVariableManager().getVariableValue("ShiftModeCode"));
vo1.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
vo1.ensureVariableManager().setVariableValue("DateTo", dateTo);
vo1.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
vo1.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
vo1.executeQuery();
System.out.println("after DetailView1Iterator vo1.getEstimatedRowCount()="+ vo1.getEstimatedRowCount());
5. What's wrong in my implementation? I don't have no problem to implement such a tree table if using simple master-detail tables view object, but now I have to use such 2 view objects using complex SQL for my requirement and variable bindings are necessary for detail view object although I also think a bit strange by myself.Hi Frank,
Thank you and it can work.
public void setLowHighSalaryRangeForDetailEmployeesAccessorViewObject(Number lowSalary,
Number highSalary) {
Row r = getCurrentRow();
if (r != null) {
RowSet rs = (RowSet)r.getAttribute("EmpView");
if (rs != null) {
ViewObject accessorVO = rs.getViewObject();
accessorVO.setNamedWhereClauseParam("LowSalary", lowSalary);
accessorVO.setNamedWhereClauseParam("HighSalary", highSalary);
executeQuery();
but I have a quesiton in this way. in code snippet, it is first getting current row of current master VO to determine if update variables value of detail VO. in my case, current row is possibly null after executeQuery() of master VO and I have to change current row manually like below.
any idea?
DCIteratorBinding dc = (DCIteratorBinding)ADFUtil.evaluateEL("#{bindings.SSForecastSourceBlockView1Iterator}");
ViewObject vo = dc.getViewObject();
vo.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
vo.ensureVariableManager().setVariableValue("DateTo", dateTo);
vo.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
vo.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
vo.executeQuery();
vo.setCurrentRowAtRangeIndex(0);
((SSForecastSourceBlockViewImpl)vo).synchornizeAccessorVOVariableValues(); -
Not able to access database from a remote machine using SQL Server Management Studio

Assigning values to 2 fields using sql statement
db11g , apex 4.0 and firefox 24 ,
hi all ,
i am trying to follow this tutorial to assign values to 2 items on a page using sql statement ,
and i am using the same sql statement the tutorial uses
select d.loc location, count(e.empno) num_employees from dept d, emp e where d.deptno = e.deptno(+) and d.deptno = :P3_DEPTNO group by d.loc -- btw , what does the "+" sign mean?
after the e.deptno in the where condition .
but i am facing this error
1 error has occurred
Wrong number of columns selected in the SQL query. See Help of attribute for details.
and it does not work with two columns in the select statement under any conditions , i tried to remove the group function and the group clause ,
it does not work unless i use only one column in the select statement ??
thanksPars
And how exactly is this rewrite of the sql statement resolving the OP's issue.
You are still using more than 1 column which will still result in the error message:
Wrong number of columns selected in the SQL query.
As mentioned in my earlier post APEX 4.0 (the version the OP is using) does not handle a sql statement with multiple columns for the dynamic action Set Value.
Which means the fastest and simplest solution is splitting up the dynamic action in multiple Set Value actions.
Using this plugin or upgrade to a newer apex version would also be a possibility.

How do you capture real detail of sql errors in crystal viewer of CR2008
How do you captue the further details of an sql error when running a report in Crystal 2008 viewer (within a software application)? I get a 'failed to retrieve data from database. Details: Database Vendor Code: -nnnn' error where nnn is a number like 210074. If I run the same .rpt directly thru crystal I get a failed to retrive rowset. Then after choosing ok on that message I get another message with more details and this time (in this particular case) it happens to be 'Column XXXXX cannot be found in database or is not specified for query. Other times it could be something about excedding max length/precison, etc..
We recently switched from using the RDC CR10 to this new .net viewer way. With the RDC it gave us the 'meaningful" message so we could tell what was wrong. Using this new method it does not. Is there a setting for showing more detail or some coding that would give me the real message detail using cr2008?
Don't know if it matters but in this case it is a Progress database.Hello,
Back in the RDC days we manually added a lot of code to capture the exception info. When CR was re-written in 9 we removed all custom "fixes" and error handling, we basically said any ANSII 92 standards rule apply. We just pass what the client gives us.
What this means is we dynamically pass the exception from the client to CR and interpret what we can or we simply pass the error code to the error UI.
What you can do is to use a try/catch block and create your own error table according to Progress Error codes to pass on a more meaningful message to your users.
We won't due to the vast amount of errors possible and the vast amount of DB clients we would have to maintain. If the client doesn't pass meaningful info onto CR then we just pass it's error onto the the end user.
Thank you

How to store a PDF in a BLOB column, then select/search it using SQL?
We have a simple requirement.
(1.) We have an Oracle 10g DB.
(2.) We want to store PDFs/MS Word docs inside BLOB column in a table.
(3.) We need to show PDF/MS Word content to the user, without opening the PDFs/MS World like we normally do (i.e. Using PDV reader/ MS Word).
(4.) i.e. We need to use SQL statements and
(a.) Get all contents of the PDF/MS WORD doc.
(b.) Search for specific strings inside these docs in the BLOB columns.How to do this pls? Code sample would be really great.

Really? You mean as opposed to a requirement that might actually be doable?Could be that simple is used as in stupid ? Like in, "+look at this simply idiotic requirement, blah.. blah...+"? ;-)
@user12240205:
BLOBs contains binary data. Not text data. How do you propose to search binary data for strings?
PDF and Word formats include actual text strings and identifiers as part of the formatting. How do you propose that this be identified and ignored when searching for specific strings in the document's content?
PL/SQL does not have the ability to take a page from a PDF/Word document, highlight the search string, and display that to the client. A format-parser is needed to parse the PDF/Word format and generate that as content (e.g. HTML or XML) that can be rendered by a client. How do you propose PL/SQL serves up search strings that it found, when it cannot interpret the document format? (cannot even say what page, section or paragraph, that search string occurs)
Documents can be loaded via the DBMS_LOB interface. Either from the db server's file system, or by the client supplying the document as chunks for "write appending" to a BLOB. See Oracle® Database PL/SQL Packages and Types Reference guide for details.
Text search and document indexing are supported by an Oracle feature called Content Management<a> (which includes interMedia, UltraSearch, Oracle Text, etc).
Oracle also supports (on Window server platforms), the Microsoft Component Object Model (COM). COM interfaces (such as COM for Word) can be used for specialised processing (e.g. searching Word documents). Oracle's COM feature allows one to interface directly with external s/w (e.g. MS Word) via its COM interface. -
Audit stored procedure execution details in sql server
Hi All,
how to find stored procedue details and which parameters passed in stored proceduer and out put details in sql server.
how can we audit stored procedure details.
/Raghavendrahttp://technet.microsoft.com/en-us/library/ms189751.aspx
In SQL Server, requires ALTER ANY LOGIN permission on the server or membership in the securityadmin fixed server role.
In SQL Database, only the server-level principal login (created by the provisioning process) or members of the loginmanager database role in the master database can create
new logins.
If the CREDENTIAL option is used, also requires ALTER ANY CREDENTIAL permission on the server.

How to use SQL*loader in oracle9i???
Hi,
I have installed oracle9i, and want to use sql*loader to load text data into table.
However, I can not find a tool called SQL*loader anywhere on the manu.
It will be appreciated if some experts can give me an advice where I can find it, and how to use it to load text data.
Thanks.
ChuckWhen I go to tahiti.oracle.com and search on "external table", I get dozens of hits that explain how to create an external table and give numerous examples. If you have specific questions, I'd be happy to try to go into more detail. A generic SQL*Loader guide, however, would be well bayond the scope of this forum.

How to numberformat when using sql:query alogn with c:forEach JSTL tags
Is there anyway to format the numeric values returned from the database when using <sql:query> alogn with <c:forEach> tags
Here is my jsp code
<sql:query..../>
<c:forEach var="row" items="${queryResults.rows}">
<tr>
<td><c:out value="${row.COL1}" /></td>

Col1 values are numeric without any formats Eg: 1000, 10000, 1000000 etc.
how can i format them to 1,000 , 10,1000 , 100,000 etcIt is polite to mention what your answer was. These posts are not just here for you to ask questions, but to be used as a resource for other people to find answers. Saying "I solved it" with no details helps noone.

Problem : Load PDF or similiar files( stored at operating system) into an oracle table using SQl*Loader .
and than Unload the files back from oracle tables to prevoius format.
I 've used SQL*LOADER .... " sqlldr " command as :
" sqlldr scott/[email protected] control=c:\sqlldr\control.ctl log=c:\any.txt "
Control file is written as :
LOAD DATA
INFILE 'c:\sqlldr\r_sqlldr.txt'
REPLACE
INTO table r_sqlldr
Fields terminated by ','
id sequence (max,1) ,
fname char(20),
data LOBFILE(fname) terminated by EOF )
It loads files ( Pdf, Image and more...) that are mentioned in file r_sqlldr.txt into oracle table r_sqlldr
Text file ( used as source ) is written as :
c:\kalam.pdf,
c:\CTSlogo1.bmp
c:\any1.txt
after this load ....i used UTL_FILE to unload data and write procedure like ...
CREATE OR REPLACE PROCEDURE R_UTL AS
l_file UTL_FILE.FILE_TYPE;
l_buffer RAW(32767);
l_amount BINARY_INTEGER ;
l_pos INTEGER := 1;
l_blob BLOB;
l_blob_len INTEGER;
BEGIN
SELECT data
INTO l_blob
FROM r_sqlldr
where id= 1;
l_blob_len := DBMS_LOB.GETLENGTH(l_blob);
DBMS_OUTPUT.PUT_LINE('blob length : ' || l_blob_len);
IF (l_blob_len < 32767) THEN
l_amount :=l_blob_len;
ELSE
l_amount := 32767;
END IF;
DBMS_LOB.OPEN(l_blob, DBMS_LOB.LOB_READONLY);
l_file := UTL_FILE.FOPEN('DBDIR1','Kalam_out.pdf','w', 32767);
DBMS_OUTPUT.PUT_LINE('File opened');
WHILE l_pos < l_blob_len LOOP
DBMS_LOB.READ (l_blob, l_amount, l_pos, l_buffer);
DBMS_OUTPUT.PUT_LINE('Blob read');
l_pos := l_pos + l_amount;
UTL_FILE.PUT_RAW(l_file, l_buffer, TRUE);
DBMS_OUTPUT.PUT_LINE('writing to file');
UTL_FILE.FFLUSH(l_file);
UTL_FILE.NEW_LINE(l_file);
END LOOP;
UTL_FILE.FFLUSH(l_file);
UTL_FILE.FCLOSE(l_file);
DBMS_OUTPUT.PUT_LINE('File closed');
DBMS_LOB.CLOSE(l_blob);
EXCEPTION
WHEN OTHERS THEN
IF UTL_FILE.IS_OPEN(l_file) THEN
UTL_FILE.FCLOSE(l_file);
END IF;
DBMS_OUTPUT.PUT_LINE('Its working at last');
END R_UTL;
This loads data from r_sqlldr table (BOLBS) to files on operating system ,,,
-> Same procedure with minor changes is used to unload other similar files like Images and text files.
In above example : Loading : 3 files 1) Kalam.pdf 2) CTSlogo1.bmp 3) any1.txt are loaded into oracle table r_sqlldr 's 3 rows respectively.
file names into fname column and corresponding data into data ( BLOB) column.
Unload : And than these files are loaded back into their previous format to operating system using UTL_FILE feature of oracle.
so PROBLEM IS : Actual capacity (size ) of these files is getting unloaded back but with quality decreased. And PDF file doesnt even view its data. means size is almot equal to source file but data are lost when i open it.....
and for images .... imgaes are getting loaded an unloaded but with colors changed ....
Also features ( like FFLUSH ) of Oracle 've been used but it never worked
ANY SUGGESTIONS OR aLTERNATE SOLUTION TO LOAD AND UNLOAD PDFs through Oracle ARE REQUESTED.
------------------------------------------------------------------------------------------------------------------------Thanks Justin ...for a quick response ...
well ... i am loading data into BLOB only and using SQL*Loader ...
I've never used dbms_lob.loadFromFile to do the loads ...
i 've opend a file on network and than used dbms_lob.read and
UTL_FILE.PUT_RAW to read and write data into target file.
actually ...my process is working fine with text files but not with PDF and IMAGES ...
and your doubt of ..."Is the data the proper length after reading it in?" ..m not getting wat r you asking ...but ... i think regarding data length ..there is no problem... except ... source PDF length is 90.4 kb ..and Target is 90.8 kb..
thats it...
So Request u to add some more help ......or should i provide some more details ?? -
IBM DB2 to Oracle Database Migration Using SQL Developer
Hi,
We are doing migration of the whole database from IBM DB2 8.2 which is running in WINDOWS to Oracle 11g Database in LINUX.
As part of pre-requisites we have installed the Oracle SQL Developer 4.0.1 (4.0.1.14.48) in Linux Server with JDK 1.7. Also Established a connection with Oracle Database.
Questions:
1) How can we enable the Third Party Database Connectivity in SQL Developer?
I have copied the files db2jcc.jar and db2jcc_license_cu.jar from the IBM DB2 (Windows) to Oracle (Linux)
2) Will these JAR files are universal drivers? will these jar files will support in Linux platform?
3) I got a DB2 full privileged schema name "assistdba", Shall i create a new user with the same name "assistdba" in the Oracle Database & grant DBA Privillege? (This is for Repository Creation)
4) We have around 35GB of data in DB2, shall i proceed with ONLINE CAPTURE during the migration?
5) Do you have any approx. estimation of Time to migrate a 35 GB of data?
6) In-case of any issue during the migration activity, shall i get an support from Oracle Team (We have a Valid Support ID)?
7) What are all the necessary Test Cases to confirm the status of VALID Migration?
Request you to share the relevant metalink documents!!!

[email protected]Hi Klaus,
Continued with the above posts - Now we are doing another database migration from IBM DB2 to Oracle, which is very less of data (Eg: 20 Tables & 22 Indexes).
As like previous database migration, we have done the pre-requirement steps.
DB Using SQL Developer
Created Migration Repository
Connected with the created User in SQL Developer
Captured the Source Database
Converted Captured Model to Oracle
Before Translation Phase we have clicked on the "Proceed Summary"
Captured Database Objects & Converted Database Objects has been created under PROJECT section.
Here while checking the status of captured & converted database objects, It's showing the below chart as sample:

We have seen only "Missing" in the chart, also we couldn't have any option to trace it in Log file.
Only after the status is VALID, we can proceed with the Translation & Migration PHASE.
Kindly help us how to approach this issue now.
Thanks

Problem using SQL Loader with ODI
Hi,
I am having problems using SQL Loader with ODI. I am trying to fill an oracle table with data from a txt file. At first I had used "File to SQL" LKM, but due to the size of the source txt file (700MB), I decided to use "File to Oracle (SQLLDR)" LKM.
The error that appears in myFile.txt.log is: "SQL*Loader-101: Invalid argument for username/password"
I think that the problem could be in the definition of the data server (Physical architecutre in topology), because I have left blank Host, user and password.
Is this the problem? What host and user should I use? With "File to SQL" works fine living this blank, but takes to much time.
Thanks in advanceI tried to use your code, but I couldn´t make it work (I don´t know Jython). I think the problem could be with the use of quotes
Here is what I wrote:
import os
retVal = os.system(r'sqlldr control=E:\Public\TXTODI\PROFITA2/Profita2Final.txt.ctl log=E:\Public\TXTODI\PROFITA2/Profita2Final.txt.log userid=MYUSER/myPassword @ mySID')
if retVal == 1 or retVal > 2:
raise 'SQLLDR failed. Please check the for details '
And the error message is:
org.apache.bsf.BSFException: exception from Jython:
Traceback (innermost last):
File "<string>", line 5, in ?
SQLLDR failed. Please check the for details

Default form value using sql with bind variable
I wish to create a form based upon a table with a foreign key. I wish to add a field to the form that is an uneditable text field with a default value using sql of 'select name from other_table where other_table_id = ?' where ? is a bind variable defined by a hidden field which is the value of the foreign key identified at runtime. How can this be done?
nullI don't think that will work. I have multiple people accessing the Portal at the same time with the same login (or lack of as public will be the most common user). I could set it easily enough as the value is passed to the form by a link object, so I could add it to the before page plsql block and set the value. But I am uncertain how it will behave in a multi-user mutlitasking environment.
Maybe I should describe what I am looking to accomplish. I want to create a display above a form that will list static details from other tables (i.e. when editing a user's phone number, which is in one table, you want the user to see the person's name, which is in another table, and the form is based upon the phone table) ...
Just as I am thinking about it, I thought of an idea. I could put some specific code in the before displaying page plsql section to query the database and use htp to output the information for data not in the table the form is based upon. I will try this and see how it works. It would have been nice to have just created a field that is not editable and had a default value, but this should work as well.
Let me know if you see any problem with this or if you have any better suggestions.
Thanks for the fast response.
