SQL Satment with JSP

Hey,
I tried to make basic SQL statment (included in a string), but one of my field have a name finishing with a + like "Group-Id+"
This is a sample of my code :
String strSQL="SELECT HelpDeskCases.Group-ID+ FROM HelpDeskCases"
I tried thanks to different ways as :
strSQL="SELECT HelpDeskCases.[Group-ID+] FROM HelpDeskCases"
strSQL="SELECT HelpDeskCases.Group" + "-" +"ID" + "+" +" FROM HelpDeskCases"
It's always crash with an error message as column name MYCOLUNM not found
Or From not found,...
In the same time I can't use system.out.println
IS someone able to help me (I'm become crazy)?

try including the column name in double quotes..
ie.
String strSQL="SELECT HelpDeskCases.\"Group-ID+\" FROM
HelpDeskCases"

SQL query with JSP and WML-parameters

Hey,
Could you help me?
I'm trying to do the following. WML deck card 1 send parameter to same WML deck's card help. I try to read the parameter with JSP in card help by putting the parameter to SQL query, but it doesn't work. I can read the parameter with WML in card help. I can also print the value of the parameter with JSP if I generate WML with JSP.
/*parameter sending from card 1 to card help*/
out.println("<go href='#helpcard'>");
out.println("<setvar name='valittukurssi' value='$(valittukurssi)'/>");
/*parameter read with WML in card help */
<p>Valitse kurssi.
$valittukurssi</p>
/'parameter read with JSP by generating WML with JSP*/
out.println("<p>$valittukurssi</p>");
/* SQL query with JSP */
ResultSet uudettulokset = uusilause.executeQuery("select * from kurssi where lyhenne='$valittukurssi'");
Thanks,
Rampe

You're problem is easy to fix. You're confusing WML variables with JSP variables. See below:
>
/*parameter sending from card 1 to card help*/
out.println("<go href='#helpcard'>");
out.println("<setvar name='valittukurssi'
value='$(valittukurssi)'/>");
Above you set a var that will work on the phone, not in JSP.
/*parameter read with WML in card help */
<p>Valitse kurssi.
$valittukurssi</p>
Yes the above does display the parameter, because it is a client side WML var, but you cannot use this variable in the JSP code (that's why your SWL fails).
/'parameter read with JSP by generating WML with
JSP*/
out.println("<p>$valittukurssi</p>");Here's you're problem, the above line is EXACTLY the same as the one before it. When the container parses through this JSP code it translates the above line to:
<p>$valittukurssi</p> on the WML page and the CLIENT uses it's local variable to display it.
What you need and want is to have a variable that can be used in JSP code and output to your WML page. Here's how it's done:
out.println("<go href='#helpcard'>");
String some_name = "valittukurssi";
out.println("<setvar name='"+some_name+"'
value='$("+some_name+")'/>");
//note that you may have to escape the ( and ) with a \
//so we displayed the variable above into the WML page, now we can use it in the SQL query:
/* SQL query with JSP */
ResultSet uudettulokset =
uusilause.executeQuery("select * from kurssi where
lyhenne='"+some_name+"'");//the end of the command is: " ' " ) ;

SQL problem with JSP

In sql statements with JSP. Heres the deal:
Access database:
Tablename: EVENT
FieldName: event_id
DataType: Number
I want to compare the event_id to an integer variable called "var" in a WHERE clause in an SQL statement through a JSP.
String query = "SELECT * FROM EVENT WHERE EVENT.event_id = 'var' ";
It says "Data type mismatch in criteria expression."
Any Suggestions? I thought this should be straight forward! am i missing something?

if i am reading correctly "var" is an int variable correct? If this is the case then the following will work;
String query = "SELECT * FROM EVENT WHERE EVENT.event_id = " + Interger.toString(var) ;
Hope that helps ( and i hope i read your problem correctly)

Best way to create, modify, XML with JSP ? HELP

Hi friends,
As i am new to XML,
I know there are two APIs used for XML processing, i want to know as a begineer level, which API
is easy and good to implement XML with JSP.
1) SAX
2) DOM
i want to make a log file in XML, so on web page it will be displayed on HTML form through XSL.
Since there is good tutorial on http://www.w3schools.com/dom
but i think its HTML dom
I want XML procession through JAVA CODE , what should i use ? and give some good tutorials on XML DOM
that is used with JAVA / JSP.
HELP.
Edited by: Ghanshyam on Sep 19, 2007 3:24 PM

Well what i think is you gonna checkout with your requirements before implementing any of the popular XML parsing mechnisms.
If you are intrested in faster processing @sacrifising a gud amount of your Memory,DOM is the one which you are looking for.
If you are instrested in Managing your memory and but if you are ok with sacrifising speed SAX is the best solution.it works on what is called a push technology.
and if you think either way you might have to look towards a pull parser which is StAX (Streaming API for XML Parsing)
it'd be a gr8 idea if you can go through the below article which explians about each of the parsing mechanisms
http://www.stylusstudio.com/xml/parser.html#*
coming back to helpful resources as far java is concern checkout the below link which might be of some help.
and the main thing is that all of these parser there is a defined specification you might find implementations of different vendors on this.
eg:Sun Provides one with JDK itself,same as IBM provides one,oracle does the same & so on...
your first task would be to focus on one such implementation which can cater your requirements.

Inserting your own sql-statements in JSP

How do I use my own sql-statements in JSP combined with the ones
generated by JDeveloper?
It seems to me that the following sentences are the ones
generating the sql for inserting in a database:
<jbo:DataSource id="ds" appid="MimPKG.MimPKGModule"
viewobject="BidragView"/>
<jbo:Row id="newRow" datasource="ds" action="Create">
<jbo:SetAttribute dataitem="*"/>
</jbo:Row>
I would like to have more control and therefore I need to make
my own sql-statements.
Is that possible?
Thanks
Leise

You can use ExecuteSQL data tag to do so. It allows you to
include your own query like insert, update etc.

Dynamic Queries with JSP

I am developing a search page which should first bring the results sorted by some particular field & then the user should have the option of sorting the results by other field names which are provided in a form list.
For generating dynamic requests, ? is used in place of parameter. But for some reason it is not working with Order by. Other dynamic queries are working fine. Please let me know the right way to handle it.
And also if someone can advise a good reference book for dynamic SQL statements in accordance with JSP.
Thanks for your time.

Never mind my previous solution. Some success was not perfect, therefore not acceptable. I used a scriplet and the problem is solved!

    <%
      String sql = "select * from issue_list_view";
      String where = null;
      String param = null;
      // Status
      param = (String)pageContext.getAttribute("status");
      if(param != null && param.compareTo("")!=0)
        where = "status='"+param+"'";
      else
        where = "status not in ('Closed','Duplicate')";
      // Assigned To
      param = (String)pageContext.getAttribute("assign");
      if(param != null && param.compareTo("")!=0)
        if(where.length()>0) {where += " and ";}
        where = "category='"+param+"'";
      // Category
      param = (String)pageContext.getAttribute("category");
      if(param != null && param.compareTo("")!=0)
        if(where.length()>0) {where += " and ";}
        where = "category='"+param+"'";
      // Type
      param = (String)pageContext.getAttribute("type");
      if(param != null && param.compareTo("")!=0)
        if(where.length()>0) {where += " and ";}
        where += "issue_type='"+param+"'";
      // Id
      param = (String)pageContext.getAttribute("id");
      if(param != null && param.compareTo("")!=0)
        if(where.length()>0) {where += " and ";}
        where += "issue_id="+param;
      // Add where clause if needed
      if(where != null) { sql += " where " + where; }

Help me plz with JSP

Hi we r making some projects with JSP as front end and SQL as a back end and we want to version our Site but i dont know how to version a web bed application ....cuz we are not using an of activeX controls or any other control..........plz help me

jsp pages are just flat files as everithing else. You can use common repositories for versioning - like MS SourceSafe, CW-RCS, ...
I've done some web projects and used CW-RCS, which is free for single user sucessfully. Everithing that you have to do is to specify the development directory of your code. After you finish vith an implementation you just commit to the repository.
Repository offers you also the comparation between the versions of code and reinstalling the old code in case ...
Hope it helps,

The syntax for accessing MS SQL db from JSP

Can anybody help me with the syntax for accessing MS SQL db from JSP???
This is what I do when I use MySQL:
Class.forName( "org.gjt.mm.mysql.Driver" );
Connection conn = DriverManager.getConnection(
"jdbc:mysql:://um" ,
What do I write when it is MS SQL and where do I install the driver

One way of doing this is to use ODBC. Here's an example:

What RAD tool should i use with JSP??

I would like to know what RAD (opensource) to use to work with JSP and MySQL.
If anyone could help
thank you

If you are using the Sun Java System Enterprise Studio, the Web Application Framework will provide you with all the tools you need to create a JSP/Servlet based web application that scales in performance like no other framework. Coupled with a WYSIWYG HTML editor like Dreamweaver and your RAD app dev is covered.
For MySQL, there are some really nice GuI clients out there. This is a link to the one I have used:
http://www.mysql.com/products/
If you are using the Sun Java Studio, don't forget to add the MySQL jdbc driver so that you can access your DB at development time and use the Sql Model wizards from within the Web Application Framework tools.
If your app is not concerned with serious scalability, and you are looking to build your app using the latest standards (JSF - Java Server Faces), you can download the Sun Java Studio Creator. It's more of a VB.NET/ASP like development environment with a WYSIWYG HTML form painter. Very slick. You can download here:
http://developers.sun.com/prodtech/javatools/jscreator/index.jsp
Here's a primer for Creator:
http://developers.sun.com/prodtech/javatools/jscreator/reference/techart/primer.html
The Creator forum is here:
http://swforum.sun.com/jive/forum.jspa?forumID=123
To recap, use Web Application Framework if you require the utmost in a mature, stable, and scalable web application. WAF apps can be deployed to any J2EE server.
If you require a webapp based on the latest standard JSF implementation, and dev productivity is more important than enterprise strength scalability, then Creator is a great choice.

Can't update a sql-table with a space

Hello,
In a transaktion I'm getting some Values from a SAP-ERP System via JCO.
I update a sql-table with this values with a sql-query command.
But sometimes the values I get from SAP-ERP are empty (space) and I'm not able to update the sql-table because of a null-value exception. (The column doesn't allow null-values). It seems that MII thinks null and space are the same.
I tried to something like this when passing the value to the sql-query parameter but it didn't work:
stringif( Repeater_Result.Output{/item/SCHGT} == "X", "X", " ")
stringif( Repeater_Result.Output{/item/SCHGT} == "X", "X", " ")
this works but I don't want to have a "_"
stringif( Repeater_Result.Output{/item/SCHGT} == "X", "X", "_")
Any suggestions?
thank you.
Matthias

The problem is Oracle doesn't know the space function. But it knows a similar function: NVL --> replaces a null value with something else. So this statement works fine for me:
update marc set
LGort = '[Param.3]',
dispo = '[Param.4]',
schgt = NVL('[Param.5]', ' '),
dismm = '[Param.6]',
sobsl = NVL('[Param.7]',' '),
fevor = '[Param.8]'
where matnr = '[Param.1]' and werks = '[Param.2]'
If Param.5 or Param.7 is null Oracle replaces it with a space in every other case it is the parameter itself.
Christian, thank you for your hint with the space function. So I remembered the NVL-function.
Regards
Matthias

SQL query with Bind variable with slower execution plan

I have a 'normal' sql select-insert statement (not using bind variable) and it yields the following execution plan:-
Execution Plan
0 INSERT STATEMENT Optimizer=CHOOSE (Cost=7 Card=1 Bytes=148)
1 0 HASH JOIN (Cost=7 Card=1 Bytes=148)
2 1 TABLE ACCESS (BY INDEX ROWID) OF 'TABLEA' (Cost=4 Card=1 Bytes=100)
3 2 INDEX (RANGE SCAN) OF 'TABLEA_IDX_2' (NON-UNIQUE) (Cost=3 Card=1)
4 1 INDEX (FAST FULL SCAN) OF 'TABLEB_IDX_003' (NON-UNIQUE)

1095 bytes received via SQL*Net from client
3 SQL*Net roundtrips to/from client
1 sorts (memory)
0 sorts (disk)
55 rows processed
I have the same query but instead running using bind variable (I test it with both oracle form and SQL*plus), it takes considerably longer with a different execution plan:-
Execution Plan

TABLEA has around 3million record while TABLEB has 300 records. Is there anyway I can improve the speed of the sql query with bind variable? I have DBA Access to the database
Regards
Ivan

Many thanks for your reply.
I have run the statistic already for the both tableA and tableB as well all the indexes associated with both table (using dbms_stats, I am on 9i db ) but not the indexed columns.
for table I use:-
begin
dbms_stats.gather_table_stats(ownname=> 'IVAN', tabname=> 'TABLEA', partname=> NULL);
end;
for index I use:-
begin
dbms_stats.gather_index_stats(ownname=> 'IVAN', indname=> 'TABLEB_IDX_003', partname=> NULL);
end;
Is it possible to show me a sample of how to collect statisc for INDEX columns stats?
