Help with Like Prepared statement

Hi,
Below is a part of the code in my test application which I am using for searching the phone book.
I want to do a pattern search with like, but for some reason, my code is not fetching me the results.
It just gives Zero results.
But if i use "=" it works fine.
I have highlighted the important part
Can you please guide me to correct this code ?
public class DBprgm {
ResultSet result;
public ResultSet getSearch(String a) {
          try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:source", "sa" , "");
Statement st = con.createStatement();
PreparedStatement ps = con.prepareStatement("select from friends where fname like ? ");*
*String x = "%"+a+"%";*
*ps.setString(1, x);*
result = ps.executeQuery();
     catch (SQLException s){
          s.printStackTrace();
     catch (ClassNotFoundException c){
          c.printStackTrace();
     return result;
}

Your code leaks Connections! You create a Connection and never close it, that's a pretty bad idea.
What database are you using? From a quick glance the code seems correct (apart from the problem I mentioned above, of course).
Edit: also, I see that you're using the JDBC-ODBC bridge. That JDBC driver has only very limited functionality and also has a few tiny bugs. Generally I'd strongly suggest that you avoid it and use your databases native JDBC drivers instead. Maybe that's also the problem here, but I can't say for sure.

Need help with the session state value items.

I need help with the session state value items.
Trigger is created (on After delete, insert action) on table A.
When insert in table B at least one row, then trigger update value to 'Y'
in table A.
When delete all rows from a table B,, then trigger update value to 'N'
in table A.
In detail report changes are visible, but the trigger replacement value is not set in session value.
How can I implement this?

You'll have to create a process which runs after your database update process that does a query and loads the result into your page item.
For example
SELECT YN_COLUMN
FROM My_TABLE
INTO My_Page_Item
WHERE Key_value = My_Page_Item_Holding_Key_ValueThe DML process will only return key values after updating, such as an ID primary key updated by a sequence in a trigger.
If the value is showing in a report, make sure the report refreshes on reload of the page.

Help with this update statement..

Hi everyone,
I am trying to update a column in a table .I need to update that column
with a function that takes patient_nbr and type_x column values as a parameter.
That table has almost "300,000" records. It is taking long time to complete
almost 60 min to 90 min.
Is it usual to take that much time to update that many records?
I dont know why it is taking this much time.Please help with this update statement.
select get_partner_id(SUBSTR(patient_nbr,1,9),type_x) partner_id from test_load;
(it is just taking 20 - 30 sec)
I am sure that it is not the problem with my function.
I tried the following update and merge statements .Please correct me if i am wrong
in the syntax and give me some suggestions how can i make the update statement fast.
update test_load set partner_id = get_partner_id(SUBSTR(patient_nbr,1,9),type_x);
merge into test_load a
using (select patient_nbr,type_x from test_load) b
on (a.patient_nbr = b.patient_nbr)
when matched
then
update
set a.partner_id = get_partner_id(SUBSTR(b.patient_nbr,1,9),b.type_x);
there is a index on patient_nbr column
and the statistics are gathered on this table.

Hi Justin,
As requested here are the explain plans for my update statements.Please correct if i am doing anything wrong.
update test_load set partner_id = get_partner_id(SUBSTR(patient_nbr,1,9),type_x);

Help changing to prepared statements for mysqli

I am trying to change previously working php pages from mysql to mysqli using prepared statements.
I am having problems with an error message.
Basically the page I have just changed produces a set of database results depending on list menu and check box criteria from user input. I run 2 queries, one to find the total number of records, and the other to retrieve the required subset for pagination. All works fine. However if there are no actual results found from the requested input my php script then uses an includes file which basically runs the same 2 queries but with the user criteria narrowed down so that similar options are presented to the user. This is where my problem lies, for some unknown to me reason the second set of queries is producing no results and an error:
'Attempt to read a row while there is no result set associated with the statement'
If I run the second set of queries without running the first set then the second set works fine so I know that it is not the statements themselves but something in my new code. How can the first set of queries be affecting the results of the second set?
Here is the code below which produces the first 2 queries that work, and below it the same code for the second 2 queries (which is from an 'Includes' file and is the same code exactly except the EXPECTED parameters $expected have been narrowed down in the expected array and list of params for binding).

If a result was found in the part that checks the numbers of records then the second query is run and displayed using : while ($stmt->fetch()) { ...... to display the results and then I use $stmt->free_result();
$stmt->close();
All fine no problems.
If the first query did not find a result then the second query is skipped and instead the script then uses a php includes file with exactly the same script as above except the expected params are narrowed as below: THIS IS WHEN I GET NO RESULTS – when I do expect to get a result) AND AN ERROR OF :

Yet if I run the includes file and skip the whole of the above code the code in the includes file find the result no problem. Anyway code below:

Again here I would then display the results before closing and freeing the stmt or display a message to say there were no results found from the criteria. But instead I get the error message and echoing the value of $totalRecords2 is empty.
I have been pulling my hair out for days and days over this and as it is one of the first pages I am converting from mysql to mysqli I wonder if I am missing something very obvious to someone with more experience with the code. I will be very grateful for any help, thank you in advance.

Can any body Help me to prepare statement

I want to provide dynamic table name for preparestatement that i just pass table name every time and it pass me total number in that table.
I create this prepare statement
PreparedStatement prepStmt=conn_.prepareStatement("select count(*) Total from ?");
prepStmt.setString(1,"new");
but it is giving error
[JDBC SQL Server Driver] Line 1: Incorrect syntax near 'new'.
Any body can help me??
I will appreciate.

In PreparedStatement, the setString method adds quotes at the start and at the end of your String.
So your request :
select count(*) Total from ?
is interpreted :
select count(*) Total from 'new'
One possible solution is to pass your tablename parameter directly in the precompiled request :
String myTableName = "new";
PreparedStatement prepStmt=conn_.prepareStatement("select count(*) Total from "+myTableName);
In your database, you will store as many precompiled Statement as you will call this method with different parameters.
Hope it helps !

Batch updates with callable/prepared statement?

The document http://edocs.bea.com/wls/docs70/oracle/advanced.html#1158797 states
that "Using Batch updates with the callableStatement or preparedStatement is
not supported". What does that actually mean? We have used both callable and prepared
statements with the batch update in our current project (with the Oracle 817 db).
It seems to run ok anyway.

So the documentation should state that batch updates do not work ok in old versions
of JDriver for Oracle, BUT work correctly with newer version. Additionally, batch
updates work ok when used with Oracle supplied jdbc-drivers?

It was not available in 6.X or 7.0 or 7.0SP1.

Looking for some help with building insert statements...

Hi, I am using some sql to build some insert statements for me to update a set of tables in our qa environments. The scripts that I have created were working great until someone added a column to some of the tables in the qa env which in turn makes my scripts break because I was simply building the statment to do someting like this...
insert into dest_table (select * from source_table@dblink);
But now when the coumns in the tables do not match it breaks...
This is the dynamic create script I use, can anyone help or suggest a better way to be able to build update statements update to qa tables when the columns are mismatched?
spool insert.sql
select
'insert into ' || table_name || ' (select * from ' || table_name || '@prod );' || chr(10) || ' commit;'
from user_tables
where table_name in
(select * from refresh_tablesl)
any help is greatly appreciated,
Thanks.

Help with a CASE statement

Please help me with a CASE Statement:
- When ID = 15, 16, 17, 18 then "Bad"
- when ID = 19, then "Average"
- when ID = 21, then "Good"
- else "Null"
Thank you!!

Well the 1st thing to do would be to correct my poor spelling... change    Delault : to Default :
Don't know why you would get an error stating "The result of selection formula must be a boolean". It's working fine on my machine.
If your ID field is numbers stored text you have a couple different options...
1) Convert the ID to a number...
Select ToNumber({home.noone_ID})
2) Wrap the ID values in double quotes...
   Case "15", "16", "17", "18" :
      "BAD"
Even if this were your problem... the error should be something other than the boolean thing...

Help with like in sql

Hi all,
I am having an issue with like statement with full text search
My data : BEAN PEELER
SQL STATEMENT: Select * from table where col1 like '%[^a-z]peeler[^a-z]%'
doesn't give all the results which has peeler in it (for example the above example)
instead if i use this statement
Select * from table where col1 like '%peeler%' it returns all the rows.
But, i need to check the exact word search and not subset of it.
My problem is how is my query able to detect few rows which has peeler in it but not all? please help

so did you try this?
declare @tab table(
val varchar(50));
insert into @tab values
('BEAN PEELER'),
('PEELERRRRR'),
('SOMPEERLER');
Select * from @tab where val like 'peeler' or VAL like '% Peeler %' or val like '% Peeler'

How to use in clause with variable elements with a prepared statement?

Is there any way to use a prepared statement for a query which incorporates an in clause with unknown number of elements in the list?
null

Sorry, can't be done. The PreparedStatement is precomplied, so you can't have variable number of params or unknown number of elements in a list.

Help with multiple case statements

Hello,
I am new to BO. I am on XI 3.0. SQL 2005. In Designer, I am trying to create a measure in a financial universe that would end up being multiple case statements within one select. This is what I tried to do, but it doesn't work with the two case statements. Can I use an ELSE leading into the second CASE WHEN somehow? How can I accomplish this? Sorry for my ignorance!
CASE WHEN dbo.ClientBudgetYear.DateStage1Approved > 01/01/1900 AND dbo.ClientBudgetMonth.Month = 12 THEN dbo.ClientBudgetMonth.Stage1Sales END
CASE WHEN dbo.ClientBudgetYear.DateStage1Approved > 01/01/1900 AND dbo.ClientBudgetMonth.Month = 11 THEN dbo.ClientBudgetMonth.Stage1Sales END
Any Suggestions?
Thanks,
Holly

Holly,
I don't know enough about your data or requirement to provide a solution, however, the construct that you post will not work because it causes you to build an object with multiple case statements when only one case statement per object is permitted. From what I see in your code I would be inclined to combine the two statements into one as such:
CASE WHEN dbo.ClientBudgetYear.DateStage1Approved > 01/01/1900 AND dbo.ClientBudgetMonth.Month in (11,12) THEN dbo.ClientBudgetMonth.Stage1Sales else null END
Thanks,
John

GET Total ANIs with Trafic By Area Code
select

I think that you need a "to_date" function eg
change '08/01/2001' to to_date('08/01/2001','dd/mm/yyyy')
