Thanks, SS

I don't trust compilers. Had issues over 30 years ago and never use a combined 'if' where one of the items is null.
if (lstDCP != null)
if(lstDCP.Count > 0)
lstDCPWithLAB = (from dcp in lstDCP
where dcp.FilingInd == FilingPartyInd.Y &&
dcp.HasLAC == YesNo.Y
select dcp).ToList();
jdweng
That will not happen becuase he is checking for null first then count:
This is
List<string> lst = null;
if ( lst != null && lst.Count > 0 )
different than this: this will cause null ref error
List<string> lst = null;
if ( lst.Count > 0 && lst != null )

How to Use SQL Query having IN Clause With DB Adapter

Hi,
I am using 11.1.1.5 want to find out how to Use SQL Query having IN Clause With DB Adapter. I want to pass the IN values dynamically. Any ideas.
Thanks

invoke a stored procedure, it's safer than trying to put together an arbitrary SQL statement in the JCA adapter

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>
<td><c:out value="${row.COL2}" /></td>
</tr>
</c:forEach>
Col1 values are numeric without any formats Eg: 1000, 10000, 1000000 etc.
how can i format them to 1,000 , 10,1000 , 100,000 etc

It 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.
I presume you discovered the JSTL <fmt:formatNumber> tag?

Using Linq Query in our program error is thrown :Exception has been thrown by the target of an invocation.

Hi All,
I am writing the below linq query to fetch the record from the database ,
var individualres = (from c in orgContext.CreateQuery("contact")
join a in orgContext.CreateQuery("annotation")
on c["contactid"] equals a["objectid"]
where (bool)a["isdocument"] == true && a["objectid"] == r.GUID &&
a["filename"] != null
select new
FirstName = c["firstname"],
LastName = c["lastname"],
CreatedDate=a["createdon"],
DocumentBody = (a["documentbody"] == null) ? "" : a["documentbody"],
GUID = c["contactid"],
FileName = a["filename"],
WorkStatus = (c["new_workstatus"] == null) ? "" : c["new_workstatus"],
Rank = (c["new_rank"] == null) ? "" : c["new_rank"],
State = (c["address1_stateorprovince"] == null) ? "" : c["address1_stateorprovince"],
City = (c["address1_city"] == null) ? "" : c["address1_city"]
But it is throwing the error Exception has been thrown by the target of an invocation.
if this error is related to null values into the columns , then i am handling those by using the
ternary operator.
Can anybody help me out for this issue.
thanks in advance.

Hello EmpAnsar,
>>But it is throwing the error Exception has been thrown by the target of an invocation.
From your LINQ query, it is hard to tell what the caused reason is since we do not have your exact tables and data. My suggestion is that you could narrow this issue by reducing items you want to fetch, for example, you could firstly write a sample query
without where clause and select new syntax as:
var individualres = (from c in orgContext.CreateQuery("contact")
join a in orgContext.CreateQuery("annotation")
on c["contactid"] equals a["objectid"]
select c).ToList();
To check if it would work, if so, you could add these filters and items you want step by step until reproducing this issue, this would help locate the root reason.
Update:
For this exception, i found some related threads which might be helpful to you:

Issue in select query with where clause

Hi guys,
I'm facing an issue while using select query with the where clause. When I'm selecting all the data from the table it returns the correct result. But when I'm using the where clause to get the specific rows from the table it returns no rows. But the data I'm trying to fetch using the where condition exists in the table.
Here is my query which causing the issue,
select * from mytable where myfield = 'myvalue'
But if I use the following query it returns the result correctly.
select * from mytable
Also the myfield value 'myvalue' exists in the table.
I have tried by running this query in both SQL Developer and SQL Plus. I have tried this query in mssql as well. It works perfectly and returns correct result sets for both the queries I have mentioned above. I'm unable to predict the issue as I'm new to ORACLE. Please help.
Thanks,
Ram.

Hi Ram,
I experienced an issue similar to this with a varchar2 field. Some of our records had a hidden newline character at the end of them, which was making queries like the one below fail:
select * from employees
where email = '[email protected]'The best way I found to detect this was to use
select 'XX'||email||'XX' from employeesTo make sure that there were no newlines. But that is just a guess. If you could provide some example table data and the outputs of your selects, it would be helpful.

Hierarchical query with where clause

Hi,
How can I query hierarchically a query with WHERE clause? I have a table with three fields session_id,id and root_id.
When I try with the following query,
select id, level from relation
where session_id = 79977
connect by prior id = root_id start with id = 5042;
It gets duplicate values.
I want the query to show in the hierarchical manner with a filter condition using WHERE clause. Please help me how can I achieve this. If you know any link that describes more about this, please send it.
Thanks in Advance.
Regards,
-Parmy

Hi Sridhar Murthy an others,
Thanks a lot for your/the answer. It's working for me. It saved a lot of other work around without the proper knowledge of hierarchical query. Please send me any link that describes these issues in detail and also I hope as I have mentioned in the other message, same cannot be achieved on views or ( on two different tables ???)
Any way thanks for your reply,
It's working for me.
With happiness,

Using bind variable with IN clause

My application runs a limited number of straight up queries (no stored procs) using ODP.NET. For the most part, I'm able to use bind variables to help with query caching, etc... but I'm at a loss as to how to use bind variables with IN clauses. Basically, I'm looking for something like this:
int objectId = 123;
string[] listOfValues = { "a", "b", "c"};
OracleCommand command = new OracleCommand();
command.Connection = conn;
command.BindByName = true;
command.CommandText = @"select blah from mytable where objectId = :objectId and somevalue in (:listOfValues)";
command.Parameters.Add("objectId", objectId);
command.Parameters.Add("listOfValues", listOfValues);
I haven't had much luck yet using an array as a bind variable. Do I need to pass it in as a PL/SQL associative array? Cast the values to a TABLE?
Thanks,
Nick

the code above product this output

SELECT null txt1, NULL txt2, null txt3, null txt4 FROM dual i tried using outer join but oracle complain that i cannot use outerjoin with OR clause.
can someone help modify my query to display the output below ?

Not sure you can do it with the Oracle style outer joins, but wioth ANSI style joins it is simple, actually exactly as you had it.

Strange behaviour when using connection pooling with proxy authentication

All
I have developed an ASP.NET 1.1 Web application that uses ODP.NET 9.2.0.4 accessing Oracle Database 8i (which is to be upgraded to 10g in the coming months). I have enabled connection pooling and implemented proxy authentication.
I am observing a strange behaviour in the live environment. If two users (User 1 and User 2) are executing SQL statements at the same time (concurrent threads in IIS), the following is occurring:
* User 1 opens a new connection, executes a SELECT statement, and closes this connection. The audit log, which uses the USER function, shows User 1 executed this statement.
* User 2 opens the same connection (before it is released to the connection pool?), excutes an INSERT statement, and closes this connection. The audit log shows User 1, not User 2, executed this statement.
Is this a known issue when using connection pooling with proxy authentication? I appreciate your help.
Regards,
Chris

Hi Chris,
I tried to reproduce your complaint, but was unable to. I didnt use auditting however, just a series of "select user from dual" with proxy authentication. You might want to see if you can put together a small complete testcase for this and open a sr with support.
Cheers

The question is clearly written. I don't see how you can be confused. But let's assume you are since you would not have posed the question.

There are 4 scopes or areas of variable visibility in JavaServer Pages. Which of those can areas can not be used with JavaBeans?

Hosting company does not support SQL query with OUTFILE clause

From my mysql database, I want to allow the user to run a query and produce a csv / text file of our membership database. Unfortunately, I just found out my hosting company does not support the SQL query with OUTFILE clause for MySQL database.
Are there any other options available to produce a file besides me running the query in phpadmin and making the file available to users.
Thanks. George
