Two variables in the where clause

DECLARE @Id VARCHAR(100)
DECLARE @NO VARCHAR(100)
SET @Id = 'IN'
SET @No = 10
SELECT *
FROM DBName.sys.indexes I
JOIN DBName.sys.tables T ON T.Object_id = I.Object_id
WHERE T.name like '%' +@Id + '_' +@NO+'%'
I need something like the above query that works.

Question is vague
Cant understand what you're really looking for as posted query has no obvious errors
Can you give some sample data and explain what you're trying to get as output

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.
CODE:
<% 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.next()) { %>
<% rs.updateString(3, "sold"); %>
<% rs.updateRow(); %>
<% }%>
<% rs.close(); %>
This is the ERROR it throws

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!

Function-based index with OR in the wher-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),...);
create index I_NORMAL_TPERSON_NAME on TPERSON(NAME);
create index I_FUNCTION_TPERSON_NAME on TPERSON(UPPER(NAME));
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
an OR-CONDITION.
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 I_FUNCTION_TPERSON_NAME and we have a full table scan in the execution-plan.
(This behavior we only expect with views but not with indexes.)
We ask for an advice like a 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 select-statement is:
select * FROM TPERSON
where (upper(NAME) like 'MIL%' or (NAME is null))
and (upper(FIRSTNAME) like 'MICH% or (FIRSTNAME is null))
and ...;
thank you for time..

In the realistic statement you write :
select * FROM TPERSON
where (upper(NAME) like 'MIL%' or (NAME is null))
and (upper(FIRSTNAME) like 'MICH% or (FIRSTNAME is null))
and ...;
as far as i know, NULL values are not indexed, "or (NAME is NULL)" have to generate a full table scan.

How to use a lexical variable in a WHERE clause and as a function argument.

Hello,
My report has a lexical variable which has values like 'and id in (1,3,4)'. I want to use this variable in two separate queries. In the first, it is used in the WHERE clause, something like:
.. where date is not null &var;
In the second query, the variable is used in a function call, something like:
select * from table (my_function(&var));
The trouble is that the first query works when the value of the variable is unquoted, but for the second query the value should be quoted.
Does anyone have an idea how I could solve this problem?
Thanks in advance,
Frans

Try

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

Hi,
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");
RowViewer.setReleaseApplicationResources(false);
RowViewer.getRowSet().next();
m_DeptId = (String)RowViewer.getRowSet().getCurrentRow().getAttribute("DeptIdFk");
%>
</jsp:useBean>
Thanks.

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,e.name,...,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=" | | m_DeptId);
rsn.getRowSet().getViewObject().executeQuery();
rsn.getRowSet().first();
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.

Using if logic in the where clause of a select statement

I have a select clause. And in the select clause there is a variable all_off_trt that can be 'Y' or 'N'.
In the where clause I want to make it so that if a form variable is checked and all_off_trt is 'Y' then
exclude it else if the form variable isn't checked then select it no matter what all_off_trt is.
Is there any way to include either and if statement or a case statement within the where clause to acheive this? If not is there another way of doing it?
Basically I am looking for a case statement like this
case
when all_off_trt = 'Y' and mail_para.code = 'Y' then false
else true
end

Ok, so that really doesn't solve my problem. I have 3 different fields that I need to do that with. Each combining in a select statement to print an email list, as well as other thing limiting the where clause.
This is currently what I have, tested and working 100%.
cursor email_cur is
select unique p.email,s.all_off_trt,s.all_deceased,s.no_enroll
from participant p, trialcom t, ethics s
where p.status='A'
and p.surname=t.surname
and p.initials=t.initials
and s.trial_cd = t.tricom
and s.centre = t.centre
and p.email is not null
and (t.centre in (select code from mail_parameters where user_name=user and mail_para='CENTRE')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='CENTRE'))
and (t.tricom in (select code from mail_parameters where user_name=user and mail_para='TRIAL')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='TRIAL'))
and (t.role in (select code from mail_parameters where user_name=user and mail_para='ROLE')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='ROLE'))
and (p.country in (select code from mail_parameters where user_name=user and mail_para='COUNTRY')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='COUNTRY'))
and (t.represent in (select code from mail_parameters where user_name=user and mail_para='REPRESENT')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='REPRESENT'));
This is in a program unit that runs when a button is clicked. At the end of that I need to add on the 3 case statements that help further narrow down the selection of emails to be printed. Then it prints the emails selected from this statement into a file. So it has to be done right in the select statement. The three table variables are the all_off_trt, all_deceased, and no_enroll. The form has 3 checkboxes. One for each, that when checked (giving the variable associated with the checkboxes a value of 'Y') excludes all emails that have a 'Y' in the coresponding table variable.

Using bind variable in dynamic where clause and concatenate with query

Hi,
In my procedure i am framing where clause dynamically with bind variable,When i am concatenate this with my sql query for REF CURSOR i got sql command not properly ended exception.
Is it possible to pass values to the bind variable through the dynamic variable/value?
Please advise
Thanks in advance

Re: [iPlanet-JATO] How to make an OR in the WHERE clause of a SELECT

Harry,
If you get a reference to your model, you can set the
whereClauseOverride with exactly the string you want to use. Keep in
mind that you are dealing with a the raw SQL where clause, therefore,
you must use the actual table column names and not the model's logical
field names as they could be different.
QueryModelBase queryModel = (QueryModelBase)getModel(PersonModel.class);
// you must add the "WHERE" as well
String whereClause = "WHERE firstName LIKE '%max' OR lastName LIKE '%max%'";
queryModel.setWhereClauseOverride(whereClause);
Keep in mind that this will override all where criteria: static and
dynamic where criteria. Static criteria can be declared in your model
class: setStaticWhereCriteriaString(STATIC_WHERE_CRITERIA).
You could optionally get the entire SQL statement and replace the
__WHERE__ token yourself with a string replace technique. In fact, if
you want to add an ORDER BY, you will need to get the SQL and append to
the end.
queryModel.getSelectSQL();
Hope this helps. Let me know if you have any questions

        "P_CIRCUITS_FIBER"
where   p_circuits_fiber.fiber_id = :P4000_CIRCUIT_NO
and     (select REGEXP_SUBSTR(ports_1,'[^,]+',1,1) from p_circuits_fiber) = "CPORT"."PORT_NO" "PORT_NO_1"
and     (select REGEXP_SUBSTR(ports_2,'[^,]+',1,1) from p_circuits_fiber) = "CPORT"."PORT_NO" "PORT_NO_2"{code}
Now we can see two columns references which should not be there.
I even not sure to understand why those two conditions are in the WHERE clause. But for sure, CPORT.ID cannot be equal to two values unless they are same.
Is there only one row in p_circuits_fiber ?

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

Hi
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.

JSP, Data Web Bean, BC4J: Setting the where clause of a View Object at run time

Hi,
I am trying to develop a data web bean in which the where clause of a View Object will be set at run time and the results of the query then displayed.
My BC4J components are located in one project while the coding for the data web bean is in another project. I used the following code bu t it does not work. Could you please let me know what I am doing wrong?
public void populateOSTable(int P_EmpId)
String m_whereString = "EmpView.EMP_ID = " + P_EmpId;
String m_OrderBy = "EmpView.EMP_NAME";
oracle.jbo.ApplicationModule appModule = null;
ViewObject vo = appModule.findApplicationModule("EMPBC.EMPAppModule").findViewObject("EMPBC.EMPView");
vo.setWhereClause(m_whereString);
vo.setOrderByClause(m_OrderBy);
vo.executeQuery();
vo.next();
String empName numAttrs = vo.getAttribute(EmpName);
System.out.println(empName);
Thanks.

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by JDev Team (Laura):
Here is how I have usually done mine:
1. In the JSP, use a RowsetNavigator bean to set the where clause and execute the query.
2. Use a custom web bean to process the results of the query (print to HTML).
for example:
<jsp:useBean class="oracle.jbo.html.databeans.RowsetNavigator" id="rsn" scope="request" >
<%
// get the parameter from the find form
String p = request.getParameter("p");
String s = request.getParameter("s");
// store the information for reference later
session.putValue("p", p);
session.putValue("s", s);
// initialize the app module and view object
rsn.initialize(application,session, request,response,out,"wt_bc_WT_bcModule.wtjoinView");
// set the where clause string
String theclause = "presname = '" + p + "' AND slideno=" + s;
// set the where clause for the VO
rsn.getRowSet().getViewObject().setWhereClause(theclause);
rsn.getRowSet().getViewObject().executeQuery();
rsn.getRowSet().first();
%>
</jsp:useBean>
<jsp:useBean class="wt_bc.walkthruBean" id="wtb" scope="request" >
<%
// initialize the app module and VO
wtb.initialize(application,session, request,response,out,"wt_bc_WT_bcModule.wtjoinView");
wtb.render();
%>
In this case, the render method of my custom web bean mostly gets some session variables, and prints various content depending on the session variable values.
Hope this helps.

Laura can you give the code of your walkthru bean? i wna't to initialize a viewobject, set the where clause and give that viewobject back to initialize my navigatorbar.

Merge can't accept a variable in the select clause?

oracle 10.2
I have a stored procedure.
I have a variable, vseq, which I set a sequence variable. With all other sql statements I can do
insert into table a
select vseq
from dual;
Apparently a merge can't handle variables in the select clause. I get an error. I can get it to work when I hard code a value.
this is ridiculous...

How do I modify the WHERE clause in my SQL query?

This seems like such a straight-forward part of the report design, but I'm fairly new to Crystal Reports and I only have experience with modifying reports someone else has already written. In this particular case, I just need to modify the WHERE clause of the SQL query. I can select Show SQL Query and see what statement is being used to select data, but I can't find where to modify it since it's grayed out. I see how to change the selection criteria, parameters, grouping, etc...just not the WHERE clause. The report is linked to a database used for reporting with a table created and populated by a stored procedure. I don't need to modify the stored procedure because the data I want to filter by is currently in the table--I just don't know how to filter by what I need. Here's part of the query:
SELECT "rpt_dist"."startdate", "rpt_dist"."transtype", "rpt_dist"."laborcode", "rpt_dist"."crewid", "rpt_dist"."regularhrs" FROM "Reporting"."dbo"."rpt_dist" "rpt_dist"
WHERE (rpt_dist."transtype" <> 'WORK' AND rpt_dist."transtype" <> 'WMATL') AND rpt_dist."laborcode" LIKE 'S%' AND (rpt_dist."crewid" = 'HOUS' OR rpt_dist."crewid" = 'HOUS2' ...
I would like to add another crewid to the WHERE clause. Thanks for any input.

1.Open the report in the crystal designer
2.Go to the field explorer(if hidden go to view menu->field explorer)
3.Rt. click on the database fields->choose database expert
4.Now you will see 2 columns-Available DataSource and Selected Tables
5.Rt. click on the object(ex.command) available in the Selected Tables column->Choose Edit command
6.A new Modify Command window will appear,here you can edit your SQL Query
I get to step 4 and I see the two columns including my database and the report table, but there is no command object available. If I right-click on my table, I can just view the Properties. ??
As for the other tip to modify the record selection: I don't see anywhere the other crewid values are set and if I add the one I'm missing, it doesn't modify the existing SQL Query and when I preview the report it throws off the results so that no data displays??
I'm using Crystal Reports 11.5 if that makes a difference. Thanks again.

To_Date function in the Where Clause

Hello All,
I'm having an issue using the to_date function that has me quite perplexed.
I have two varchar2 fields, one with a date value in the format Mon, DD YYYY, the other has a time value in the format HH:MI PM.
When I run my query one of the columns I retrieve looks like this TO_DATE (d4.adate || e4.atime, 'Mon DD, YYYYHH:MI PM'). The two fields are concatenated together and converted to a date. This works fine.
My problem occurs when I attempt to apply the same logic to the where clause of the aforementioned query. e.g. when I add the following criteria to my query and TO_DATE (d4.adate || e4.atime, 'Mon DD, YYYYHH:MI PM') <= sysdate I get an ORA-01843: not a valid month error.
To further illustrate my problem here are the two queries:
Select d4.adate, e4.atime, TO_DATE (d4.adate || e4.atime, 'Mon DD, YYYYHH:MI PM')
from ....
where ....
The above query works.
Select d4.adate, e4.atime, TO_DATE (d4.adate || e4.atime, 'Mon DD, YYYYHH:MI PM')
from ....
where ....
and TO_DATE (d4.adate || e4.atime, 'Mon DD, YYYYHH:MI PM') <= sysdate
The second query does not work.
The tables used and the limiting criteria are identical, except for the last one.
Does anyone have any ideas why this could be happening.
