Mm.mysql JDBC Driver and the WHERE clause

Anybody has succesfully performed a MySQL/JDBC query in a JSP application using more than one variable in the WHERE clause?
It works fine when I run queries with one fixed value assigned to a column and one variable assigned to the other column in the WHERE clause; but when I do it with more than one variable in the WHERE clause, it screws up throwing an error.
I wonder if it is a code error, a syntax error or if it is something tricky about the mm.mysql JDBC Driver. Following is a section of the code and the error. The variables are s_description and s_status. I read some examples in a book but they use SQL Server. Thank you in advance for any information.
<% String sqlStatement = "" ; %>
<% String s_description = "Mexican Style Rice" ; %>
<% String s_status = "available" ; %>
<% java.sql.Statement stmt = con.createStatement(java.sql.ResultSet.TYPE_SCROLL_INSENSITIVE, java.sql.ResultSet.CONCUR_UPDATABLE); %>
<% java.sql.ResultSet rs ; %>
<% sqlStatement = "SELECT code, description, status FROM products WHERE products.description =" + s_description + " AND products.status =" + s_status + ";" ;%>
<% rs = stmt.executeQuery(sqlStatement); %>
<% rs.beforeFirst(); %>
<% while ( { %>
<% rs.updateString(3, "sold"); %>
<% rs.updateRow(); %>
<% }%>
<% rs.close(); %>
This is the ERROR it throws
java.sql.SQLException: Column not found: Unknown column 'available' in 'where clause'

     at com.newatlanta.servletexec.ServletExec.ProcessRequest(

I think perhaps this sentence has problems:
<% sqlStatement = "SELECT code, description, status FROM products WHERE products.description =" + s_description + " AND products.status =" + s_status + ";" ;%>
You can
<% sqlStatement = "SELECT code, description, status FROM products WHERE products.description ='" + s_description + "' AND products.status = '" + s_status + "'" ;%>
You perhaps ignore the ���� when using String variable s_description and s_status.
Hope this will help you. Good lucky!

  • Oracle JDBC driver and the object types cache

    Hi there,
    Oracle JDBC Developer's Guide and Reference says (version 11gR1):
    Oracle JDBC drivers cache array and structure descriptors. This provides enormous performance benefits. However, it means that if you change the underlying type definition of a structure type in the database, the cached descriptor for that structure type will become stale and your application will receive a SQLException exception.
    That is the problem we are having here... We have web services deployed to WebLogic server that use custom object types. Every time we have to change an object type definition the web services stop working (the error ORA-00902: invalid datatype is raised) and the only solution is to restart the JDBC data source which is quite disruptive to the development process.
    Is there a workaround to disable that "feature"?

    Although if you are changing the object structure then the code to deal with it must change as well. So, especially in developement, why is restarting a problem?It is not that restarting per se is a problem. Here us developers do not have the required privileges to restart the JDBC pool and we have to ask the DBA to do it, and sometimes he is not immediately available. It is not a big thing but this can impact the development process.Your development process is hideously flawed then.
    The pool exists in the JEE server. And from your first post it seems that you have permission to restart that but not to access the management console. It is ridiculous to have access the the former and not the later.
    Not to mention that you should have your own JEE instance to develop on. Actually it is weird to me that a DBA would even be touching a JEE server. The competent ones I know don't even know how to do that. They know the database not the application servers.
    In addition, having to restart a whole JDBC pool just because you changed a database object definition does not seem very flexible to me. Such issue does not exist in other connection types, for instance in OCI connections, that is why I thought there should be an option to turn it off if required.
    Well specifically you have to restart the pool because you were USING the object that changed.
    And I am rather certain that you can turn off the pool entirely.
    Even in production, I reckon that this may have a negative impact. For instance, say that you need to deploy a hot fix for a bug in one application that involves the re-creation of one single object type. This means that the whole JDBC pool, which may be used by other applications, may have to be shut down just because of that single object.Good point.
    I suggest you stop using complex objects in Oracle. I suspect that would eliminate the problem completely.

  • Help with com.mysql.jdbc.Driver

    Hi all
    I am new to working with java. I am working off of my laptop (pc -vista) and
    am trying to connect to a database on a server I have, mac osx 10.x.
    First question: I would install com.mysql.jdbc.Driver on the same server as
    the MySql server correct?
    Second and more important question: I have multiple pages
    printed out on installing this driver but I just cannot follow it. I am not
    very good in terminal(mac) and the install seems terminal based.
    Can someone please try to explain to me in laymen terms what needs to
    be done?

    MarcusYes, you can move the jar into the ext directory if you wish. How are you running your java application? What are you typing/clicking on?

  • Function-based Index and an OR-condition in the WHERE-clause

    We have some problems with functin-based indexes and
    the or-condition in a where-clause.
    (We use oracle 8i (8.1.7))
    create table TPERSON(ID number(10),NAME varchar2(20),...);
    The following two statements run very fast on a large table
    and the execution-plan asure the usage of the indexes
    (-while the session is appropriate configured and the table is analyzed):
    1)     select count(ID) FROM TPERSON where upper(NAME) like 'MIL%';
    2)     select count(ID) from TPERSON where NAME like 'Mil%' or (3=5);
    In particular we see that a normal index is used while the where-clause contains
    But if we try the similarly select-statement
    3)     select count(ID) FROM TPERSON where upper(NAME) like 'MIL%' or (3=5);
    the CBO will not use the function-index.
    (This behavior we only expect with views but not with indexes.)
    We ask for an advice like an hint, which enable the CBO-usage
    of function-based indexes in connection with OR.
    This problem seems to be artificial because it contains this dummy logic:
         or (3=5).
    This steams from an prepared statement, where this kind of boolean
    flag reduce the amount of different select-statements needed for
    covering the hole business-logic, while using bind-variables for the
    concrete query-parameters.
    A more realistic (still boild down) version of our prepared select-statement run in
    SQL Plus:
    define x_name = 'MIL%';
    define x_firstname = '';
    select * FROM TPERSON
    where (upper(NAME) like '&x_name' or ( '&x_name' = ''))
    and (upper(FIRSTNAME) like '&x_firstname' or ('&x_firstname' = ''))
    and ...;
    In particular we dont refernce the tablecolumn , but the QUERY-Parameter
    yield the second boolean value in the or-condition.
    The problem is that this condition ('&x_name' = '') dont use any index.
    thanks a lot for spending your time with this problem

    SELECT /*+ RULE */
    as your hint. I don't have the book with me, but this last weekend I read a section about your very problem. The book was a Oracle Press gold cover about Oracle 8i Performance tuning. If you e-mail me I can quote you the chapter when I get home Friday.

  • JSP, DataWebBean: How to dynamically set the where clause of query and display record

    I am reposting this question as per suggestions made by Mr. Dwight.
    I have used ViewCurrentRecord web bean to display records from EMP table. I have to use the Dept_Id_FK from the current
    record of the EMP table to display corresponding records of Dept table. I have a view object called DeptView in my Business
    Components which selects all the records from the Dept table.
    How do I get the value of Dept_Id_FK and use it to display the required records of the Dept table?
    I tried to declare a variable and get the value of Dept_Id_FK but it did not work. My code is as follows:
    <%! String m_DeptId = null; %>
    <jsp:useBean id="RowViewer" class="oracle.jbo.html.databeans.ViewCurrentRecord" scope="request">
    RowViewer.initialize(pageContext, "EMPApp_EMP_EMPAppModule.EMPView1");
    m_DeptId = (String)RowViewer.getRowSet().getCurrentRow().getAttribute("DeptIdFk");

    First of all, Thank you very much for making use of the new topic format. It is very much appreciated.
    As for your question, I think there are several different ways to accomplish what I think you want to do.
    1. Create a view object that includes both Emp and Dept entities and join them there. In this case, your query would look something like this:
    Select e.empno,,...,d.dname,d.loc from emp e, dept d
    where e.deptno = d.deptno
    You should be able to create a JSP off of this view object that contains both the employee and department information. In this case, BC4J takes care of the foreign key to primary key coordination.
    2. In order to set a dynamic where clause for a view, you need to do the following in your usebean tag:
    rsn.initialize(application,session, request,response,out,"DeptView");
    rsn.getRowSet().getViewObject().setWhereClause("deptno=" &#0124; &#0124; m_DeptId);
    You will need to do this in a separate usebean tag from the EmpView, since the usebean can only initialize one view object.
    In other words, you would have your ViewCurrentRecord bean tag for the EmpView, then a separate one for the DeptView where you use the above code to set the where clause to display just the information for the department you want.
    Another option, but one I'm not sure would work as well, is to create a master-detail JSP to do this for you. Usually a master-detail is a one-to-many (one department to many employees). Your request appears to be the reverse, but might still be doable using the same mechanism.
    You set up relationships between views in your BC4J project using View Links. If you used the BC4J project wizard and created default views, some of these links may have been created for you. They are created when BC4J detects a foreign key to primary key relationship in the database.
    You can create your own View Links using the View Link wizard. Select your BC4J project node and choose Create View Link... from the context menu. You will be asked to select a source view (Emp), and a target view (Dept), then select the attribute in each view that related the two of them (deptno).
    Next, you need to reflect this new relationship setting in your application module. Select your app module and choose Edit from the context menu. On the data model page, select the EmpView node in the Selected list. Now select the DeptView node in the available list and shuttle it over. You should see DeptView1 via yourlink appear indented under the EmpView node. Save and rebuild your BC4J project to reflect the changes.
    In your JSP project, you can now have the wizard create a master-detail form for you based on DeptView1.
    Let me know if the above answers your question, or if I have misunderstood what it is you wanted to do.

  • How to make MySQL JDBC Driver case-insensitive

    One of the problem is that oracle's column names are
    case insensitive, whereas CODE in mySql is different from code (see example posted below).I doubt that.
    SQL standards are rather specific that columns names are case insensitive unless quoted identifiers are used. And presumably you are doing that.
    What you are seeing is a difference in drivers not databases.
    I would guess that the only way to change the behaviour is to modify your code. If you uppercase everything it should work. Or you could use positional rather than named column extraction.

    Just to show you mysql is Good. with localhost.
    mysql -u root -h localhost -p
    mysql> use javatest
    Database changed
    mysql> select * from testdata;
    | id | foo | bar |
    | 1 | hello | 12345 |
    1 row in set (0.00 sec)

    Nope, it's not a MySQL issue.
    I'd recommend NOT putting the JDBC JAR file (or any others, except Sun-sanctioned extensions) in JAVA_HOME/jre/lib/ext.
    JDBC JARs belong in TOMCAT_HOME/common/lib or in the WEB-INF/lib directory for your particular app. If you put them in the former, all apps running under Tomcat can have access to them. If you put them in the latter, only your app can see them.
    After you've done that, do some reading about JNDI data sources under Tomcat:
    That way you can get that connection code out of your JSPs and into the web.xml and <Context>, where it belongs. You'll be able to change data sources without rewriting your pages.
    Good luck - MOD

  • IDM 8.0 would not pick up MySQL jdbc driver.

    I am trying to create database table using "create new resources" in IDM.
    With orcale, I have no issue. I copy a jdbc driver to C:\idm8\WEB-INF\lib and rename it
    However, after I copyed mysql-connector-java-5.1.5-bin.jar ( which works with netbean and MySQL server on
    my PC) into the same C:\idm8\WEB-INF\lib directory ( and i tried rename it mysqljdbc.jar too),
    Database Type: MySQL
    JDBC Driver: com.mysql.jdbc.Driver
    JDBC URL TEmplate: jdbc:mysql://localhost:3306/test
    Host:     localhost
    TCP Port: 3306
    Database: test
    I got an error:
    XPRESS <invoke> exception:
    Can't call method getTableData on class com.waveset.ui.web.resources.wizard.DBTableUtil
    ==> com.waveset.util.WavesetException: ==> java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/test
    Then I tried the case where I replace localhost with IP Address and th ecase I use Fully qulified
    PC name, I got the same error.
    I know that the driver works because it is being used in NetBeans6.1
    I also tried mysql-connector-java-5.1.6-bin.jar with the same results.
    Does anyone have any ideas?

    Could your issue be with this line here:
    JDBC URL Template: jdbc:mysql://localhost:3306/testI believe it should be something like this: (As chapo pointed out)
    JDBC URL template: jdbc:mysql://%h:%p/%dThe template is exactly that, a template.. The values are filled in by the next three entries

  • How to change recordset bahaviour to accept dynamic column names in the where clause

    im using php-mysql and i make a recordset and i want to make the column names in the where clause to be dynamic like
    "select id,name from mytable where $tablename-$myvar";
    but when i do this my i break the recordset and it disappear
    and when i use variables from advanced recordset it only dynamic for the value of the column not for the column name
    and when i write the column name to dynamic as above by hand it truns a red exclamation mark on the server behaviour panel
    so i think the only way is to change the recordset behaviour is it? if so How to make it accept dynamic column names?
    thanks in advance.

    As bregent has already explained to you, customizing the recordset code will result in Dreamweaver no longer recognizing the server behavior. This isn't a problem, but it does mean that you need to lay out your dynamic text with the Bindings panel before making any changes. Once you have changed the recordset code, the Bindings panel will no longer recognize the recordset fields.
    Using a variable to choose a column name is quite simple, but you need to take some security measures to ensure that the value passed through the query string isn't attempting SQL injection. An effective way of doing this is to create an array of acceptable column names, and check that the value matches.
    // create array of acceptable values
    $valid = array('column_name1', 'column_name2', 'column_name3');
    // if the query string contains an acceptable column name, use it
    if (isset($_GET['colname']) && in_array($_GET['colname'], $valid)) {
      $col = $GET['colname'];
    } else {
      // set a default value if the submitted one was invalid
      $col = 'column_name1'
    You can then use $col directly in the SQL query.

  • Error : class not found exception : com.mysql.jdbc.driver in Eclipse Tool

    I have impoted project file in eclipse in new machine using option import from existing workbence . When i stat to debug this project ,
    i am getting error as class not found exception : com.mysql.jdbc.driver . my project folder already consist of mysql .jar file in /web appls/web-inf folder.
    Application is running successfully in other machine from where i took the application file. As this error appeared I also added jar file into project path as Project ---->properties-- build java path---libraries----add external jar file.
    kindly hep me.

    Sounds like an eclipse question - not a JDBC one.
    But since eclipse is telling you it can't find it then it means it is not in the eclipse path. So you must add it. (The fact that it is somewhere is irrelevant - all that matters is it is not in the class path.)
