SQL Statement COALESCE displays NULL
SQL Server 2008
SQL Statement
SELECT [IP_ADDR1_TEXT], COALESCE(COUNT(distinct [IP_ADDR1_TEXT]),0) as Instances
FROM sem_computer LEFT JOIN [dbo].[V_SEM_COMPUTER]
ON sem_computer.COMPUTER_ID = [dbo].[V_SEM_COMPUTER].COMPUTER_ID
AND [IP_ADDR1_TEXT] = '10.10.10.11'
GROUP BY [IP_ADDR1_TEXT]
If 10.10.10.11 doesn't exist, it returns
IP_ADDR1_TEXT Instances
NULL 0
but if it exists, then it returns
IP_ADDR1_TEXT Instances
10.10.10.11 1
How do I fix the statement so it outputs the IP address even if it doesn't exist, i.e
IP_ADDR1_TEXT Instances
10.10.10.11 0
How do I fix the statement so it outputs the IP address even if it doesn't exist, i
You would need a reference table with all possible IP address to get a "not existing" IP address

Hi
Please can you help me to create this SQL statement ?
I have two tables: table1 consist of data (AAA,BBB), table2 consist of data(AAA)
And there is relation between table1 and table2 for example (Invoice_id) .
My question is ( How can create SQL statement to display only data in table1(BBB) but not available In table2 ?
Thanks and best regards .
KhaledTry this:
SQL> ed
Wrote file afiedt.buf
1 with t as (select 'AAA' col1,1 inv_id from dual
2 UNION select 'BBB',1 from dual)
3 , s as (select 'AAA' col1,1 inv_id from dual)
4 SELECT col1,inv_id FROM t
5* WHERE NOT EXISTS (SELECT 1 FROM s WHERE inv_id = t.inv_id AND col1 = t.col1)
SQL> /
COL INV_ID
BBB 1

SQLException: Closed Connection, SQL state [null]; error code [17002]
Hello All,
I am supporting a Java 5 project on Tomcat. We've used Spring and Stored Procedure in the project.
Recently we deployed our application in a GoLive environment and have started seeing Timeout errors in log files. After around two days we also have to restart Tomcat as users are no more able to login to access the application.
Same application runs fine without any timeout issues on another environment.
The only difference between two environments is that the Go-Live env has a firewall between Tomcat and Database and the other environment hosts both Tomcat and Database on same machine (i.e. no firewall).
For GoLive env the only port open on firewall for JDBC connection is 1521 and is used in the connection string url for obtaining the connections.
When there is a Timeout error, the N/w admin guy observed that the JDBC connection was not attempted on 1521 port, but on some random port which is not open on firewall, due to which the Database server logs also do not show entry for this connection attempt as it gets blocked by the firewall.
I am not sure why a randam port should be used to connect when a specific port is mentioned in the connection url? Also what can be making this port switching?
Application uses Apache DBCP with Spring to obtain connections.
Has anyone experienced similar errors?
Any suggestions/help on this issue is greatly appreciated!
Many Thanks,
CD

Apex 4.0 display image item :BLOB column returned by SQL statement
Hello
I'm creating an display image item in apex 4.0. The source is a BLOB column returned by SQL statement.
When I'm issuing an sql statement like this:
select lado.blob_content
from large_documents lado
, large_doc_headers ladh
where lado.ladh_nr = ladh.nr
more criteriait works fine.
When I create a function inside a package with the same query (in a cursor)
function get_image(some parameters in) return blob
Following in apex by:
select get_image(some parameters) from dualI get a
ORA-06502: PL/SQL: numeric or value error: character string buffer too smallAnybody any idea why this does not work?
Regards ErikHi Eric,
the environment assumes varchar2-output by default, which will be limited to 32767 characters and may have problems with binary formats. You could define a blob-variable to select the value into.
DECLARE
l_blob BLOB;
BEGIN
SELECT get_image(some parameters)
INTO l_blob
FROM dual;
END;
/If you expect the BLOB-Content to be text (you should consider CLOB then), you may use UTL_RAW.CAST_TO_VARCHAR2 to convert the content. If your object is larger than the maximum varchar2 size, or you want to convert BLOB to CLOB, you might be interested in some converter like described here: {message:id=559749}
Hope this is what you were searching for.

Display the sql statement with arguments with ojdbc14_g.jar
Hi,
I'd like to display the sql statements with ojdbc14_g.jar.
So I've followed the documentation and set an OracleLog.properties file which is linked to my java program.
The problem is the trace generated is huge and I only need the SQL requests wich are made with the arguments but I don't know how to configure that.
Have you got a sample file which handle that ?
I've tried that :
oracle.jdbc.handlers=java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level=CONFIG
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter
oracle.level=INFO
oracle.jdbc.driver.level=OFF
oracle.jdbc.driver.OraclePreparedStatement.level=OFF
oracle.jdbc.pool.level=OFF
oracle.jdbc.util.level=OFF
oracle.sql.level=INFO
But that doesn't display only the SQL and args :(
Regards.The fact is the statement are made by ejb entities on JBoss so I don't have a way to make specific logger to display the sql order. The only thing I can do is to set the log4j org.jboss.ejb.plugins.cmp to a trace level in order to see the sql order but without the arguments.
I tried those traces however I see stuff like that without any SQL orders :

Run second sql statement only if first sql statement is null.
Hey guys I seem to have a mental block here. I have two sql statements. I would like the second to run only if the first sql statement is null.I know i can potentially use PLsql but would really like to see if i can do this with straight up sql. Your responses are very very appreciated.
here is the first sql
Select ft.fund_code,
ft.orgn_code,
ft.acct_code,
ft.amount,
fb.owner_pidm,
ft.prog_code
from ftrbremb fb , ftcractg ft
where fb.doc_code = 'TR000038'
and fb.ftpbport_id = ft.ftpbport_idsecond sql statement
Select ft.fund_code,
ft.orgn_code,

where fb.doc_code = 'TR000038'
--and fb.ftpbport_id = ft.ftpbport_id
and fx.ftrbremb_id = fb.id
and ft.ftprexps_id = fx.id;How can i combine these two statements together so that when the first one is null the second one runs. As a bonus i like to get just the first row as well.
Any help would greatly appreciated. I tried to accomplish with case statement but it just dosent seem to be working for me.

HOW TO: Post a SQL statement tuning request - template posting
This post is not a question, but similar to Rob van Wijk's "When your query takes too long ..." post should help to improve the quality of the requests for SQL statement tuning here on OTN.
On the OTN forum very often tuning requests about single SQL statements are posted, but the information provided is rather limited, and therefore it's not that simple to provide a meaningful advice. Instead of writing the same requests for additional information over and over again I thought I put together a post that describes how a "useful" post for such a request should look like and what information it should cover.
I've also prepared very detailed step-by-step instructions how to obtain that information on my blog, which can be used to easily gather the required information. It also covers again the details how to post the information properly here, in particular how to use the \ tag to preserve formatting and get a fixed font output:
http://oracle-randolf.blogspot.com/2009/02/basic-sql-statement-performance.html
So again: This post here describes how a "useful" post should look like and what information it ideally covers. The blog post explains in detail how to obtain that information.
In the future, rather than requesting the same additional information and explaining how to obtain it, I'll simply refer to this HOW TO post and the corresponding blog post which describes in detail how to get that information.
*Very important:*
Use the \ tag to enclose any output that should have its formatting preserved as shown below.
So if you want to use fixed font formatting that preserves the spaces etc., do the following:
\ This preserves formatting
\And it will look like this:
This preserves formatting
. . .Your post should cover the following information:
1. The SQL and a short description of its purpose
2. The version of your database with 4-digits (e.g. 10.2.0.4)
3. Optimizer related parameters
4. The TIMING and AUTOTRACE output
5. The EXPLAIN PLAN output
6. The TKPROF output snippet that corresponds to your statement
7. If you're on 10g or later, the DBMS_XPLAN.DISPLAY_CURSOR output
The above mentioned blog post describes in detail how to obtain that information.
Your post should have a meaningful subject, e.g. "SQL statement tuning request", and the message body should look similar to the following:

I'm sure that if you follow these instructions and obtain the information described, post them using a proper formatting (don't forget about the \ tag) you'll receive meaningful advice very soon.
So, just to make sure you didn't miss this point:Use proper formatting!
If you think I missed something important in this sample post let me know so that I can improve it.

can't reproduce, does it still look unformatted? Or are you simply kidding? :-)

PS: Just noticed that it actually sometimes doesn't show the proper formatting although the code tags are there. Changing to the \ tag helped in this case, but it seems to be odd.

Problem with sql statement after migration
Hi, recently I copied a production database X to a remote location, to serve as a test upgrade database. Original is 32 bit and test database is 64 bit. After migration it turned out that one sql statement consumed much more CPU during EXECUTE phase than on production database. Explain plans are the same. Why CPU is different? How can I trace the problem?

public synchronized Product GetProductItem (int productid) throws CategoryException
Statement stmt = null;
stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select c.CategoryName, p.ProductName from category_product cp inner join category c on cp.CategoryID = c.CategoryID inner join product p on cp.ProductID = ?");
Product p = new Product();
p.setCategoryName(rs.getString("CategoryName"));
p.setProductName(rs.getString("ProductName"));
}How can I make the SQL statement to get the int parameter productid? As I want to show the particular product with it's own id.
And, how can I display the product detail for that product? How can I show it as an object?I don't think your code will work. Don't you have to call next() on the ResultSet to advance the cursor to the first row? What if your query returns more than one row?
In either case, I think your code should look more like this:
ResultSet rs = ...;
List products = new ArrayList(); // Or something else
while (rs.next())
Product p = new Product();
// Set the values from the ResultSet
products.add(p);
rs.close();
statement.close();Once you've got those, you can either pass Product to a JSP and have it display the values or you can write the HTML response to the browser from the servlet. I'd go with JSP myself. - MOD -
How Can I Retrieve SQL Statement From The User ?
Hi
I want to know, how can I make the user can enter the SQL statement from himself ?? in this code he can't enter it. Only he can display the SQL that i wrote it...
this is my Code:
import java.sql.*;
public class db_testing {
static final String DRIVER = "com.mysql.jdbc.Driver";
static final String DATABASE_URL = "jdbc:mysql://localhost/S204111933";
public static void main(String[] args) {
Connection cn=null;
Statement st= null;
ResultSet rset=null;
try{
Class.forName(DRIVER);
cn=DriverManager.getConnection(DATABASE_URL, "root", "admin");
st=cn.createStatement();
rset=st.executeQuery("select * from employee");
ResultSetMetaData metadata=rset.getMetaData();
System.out.println("The begining: ");
for(int i=1;i<=metadata.getColumnCount();i++)
System.out.print(metadata.getColumnName(i)+"\t");
System.out.println();
System.out.println();
while(rset.next()){
for(int i=1;i<=metadata.getColumnCount();i++)
System.out.print(rset.getObject(i)+"\t\t");
System.out.println();}
catch(Exception e){
e.printStackTrace();
finally{
try{
cn.close();
st.close();
rset.close();
catch(Exception e1){
e1.printStackTrace();
}The following changes in the code will make the user to give the input
import java.sql.*;
public class db_testing {
static final String DRIVER = "com.mysql.jdbc.Driver";
static final String DATABASE_URL = "jdbc:mysql://localhost/S204111933";

// st=cn.createStatement();
// rset=st.executeQuery("select * from employee");
PreparedStatement pstmt=null;
pstmt=cn.prepareStatement("select * from employee where id=?");
pstmt.setInt(1,Integer.parseInt(args[0]));
rset=pstmt.executeQuery();
ResultSetMetaData metadata=rset.getMetaData();

This SQL statement always in Top Activity, with PX Deq Credit: send blkd
Hi gurus,
The following SQL statement is always among the Top Activity. I can see the details in Enerprise manager that it suffers from PX Deq Credit: send blkd
This is the statement:
SELECT S.Product, S.WH_CODE, S.RACK, S.BATCH, S.EXP_DATE, FLOOR(Qty_Beg) QtyBeg_B,
ROUND(f_convert_qty(S.PRODUCT, Qty_Beg-FLOOR(Qty_Beg), P.UOM_K ), 0) QtyBeg_K,
FLOOR(Qty_In) QtyIn_B, ROUND(f_convert_qty(S.PRODUCT, Qty_In-FLOOR(Qty_In), P.UOM_K), 0) QtyIn_K,
FLOOR(Qty_Out) QtyOut_B, ROUND(f_convert_qty(S.PRODUCT, Qty_Out-FLOOR(Qty_Out), P.UOM_K ), 0) QtyOut_K,
FLOOR(Qty_Adj) QtyAdj_B, ROUND(f_convert_qty(S.PRODUCT, Qty_Adj-FLOOR(Qty_Adj), P.UOM_K ), 0) QtyAdj_K,
FLOOR(Qty_End) QtyEnd_B, ROUND(f_convert_qty(S.PRODUCT, Qty_End-FLOOR(Qty_End), P.UOM_K ), 0) QtyEnd_K,
S.LOC_CODE
FROM V_STOCK_DETAIL S
JOIN PRODUCTS P ON P.PRODUCT = S.PRODUCT
WHERE S.Product = :pProduct AND S.WH_CODE = :pWhCode AND S.LOC_CODE = :pLocCode;The statement is invoked by our front end (web based app) for a browse table displayed on a web page. The result can be 10 to 8000. It is used to display the current stock availability for a particular product in a particular warehouse. The stock availability it self is kept in a View : V_Stock_Detail

Hi sir,
How to prevent the query from doing parallel query ?
Because as you see actually I am not issuing any Parallel hints in the query.
Thank you,
xtantoKristanto,
there are a couple of points to consider:
1. Your SQL*Plus version seems to be outdated. Please use a SQL*Plus version that corresponds to your database version. E.g. the AUTOTRACE output is odd.
2. I would suggest to repeat your exercise using serial execution (the plan, the autotrace, the tracing). You can disable parallel queries by issuing this in your session:
ALTER SESSION DISABLE PARALLEL QUERY;
This way the output of the tools is much more meaningful, however you might get a different execution plan, therefore the results might not be representative for your parallel execution.
3. The function calls might pose a problem. If they are, one possible damage limitation has been provided by hoek. Even better would be then to replace the PL/SQL function with equivalent plain SQL. However since you say that it generates not too many rows it might not harm here too much. You can check the impact of the functions by running a similar query but omitting the function calls.
4. The parallel execution plan contains a MERGE JOIN CARTESIAN operation which could be an issue if the estimates of the optimizer are incorrect. If the serial execution still uses this operation the TKPROF and DBMS_XPLAN.DISPLAY_CURSOR output will reveal whether this is a problem or not.
5. The execution of the statement seems to take on 2-3 seconds in your tests. Is this in the right ballpark? If yes, why should this statement then be problematic? How often does it get executed?
6. The statement uses bind variables, so you might have executions that use different execution plans depending on the bind values passed when the statement got optimized. You can use DBMS_XPLAN.DISPLAY_CURSOR using NULL as "child_number" parameter or DBMS_XPLAN.DISPLAY_AWR (if you have a AWR license) to check if you have multiple execution plans for the statement. Please note that older versions might have already been aged out of the shared pool, so the AWR repository might be a more reliable source (but only if the statement has been sampled).
7. You have disabled cost based transformations: "_optimizer_cost_based_transformation" = OFF. Why?

Randolf

And I would like to know, how can I include the GROUP BY in order to generateI think your question got cut off. What are you trying to generate with this SQL? I should say in advance that Oracle Designer has very few places where you can enter a SELECT command directly. You can usually get it to generate what you need by choosing the correct Table Definition (or View Definition) usages, choosing the display columns you want, and adding WHERE clauses and GROUP BY columns.
With something as complex as your Statement, I would probably consider creating a View, then use the View in modules. -
HELP: Bind Variable does't work in SQL statement
I am trying to connect a text item bind variable into the where
clause of an SQL statement. Specifically into an INSERT
statement and SELECT statement. It gives me an message box
error, saying it is unable to insert. There is no Oracle error
number associated with it. Is this a bug? Has this happened to
anyone else. PLEASE HELP! URGENT!
nullI assume this is a forms problem. You need to check out the
dbms_error_code and dbms_error_text to get your oracle error.
You can trap and report these types of errors using an on-error
trigger. Also, if you are using the default menu then check
out help -> display error immediately after the form reports
unable to insert ...... This should give you enough information
to solve your problem, or at least point you in the right
direction.
