Execute A select statement under Oracle connection?

Hi,
How can i execute a select statement
under an existing Oracle connecton without
defining extera JDBC connection.

Be aware that you can create View Objects that are NOT based on entity objects. In this case, they are read only, but if you just want to display results, or check for a specific value, it at least reduces the overhead of an EO.
I'm not sure that answers the question here, but thought I would at least throw it out there.
In the View Object wizard, on the page that asks you to choose an EO, just click Next without selecting any EOs. This will automatically put you in expert query mode. Just type in your query and go.
You do have to be a little careful with expert mode queries, especially if you go back and edit them later. You need to make sure to keep the attribute mapping in synch on the Attribute page.
Also, I have found some limitations to this approach, which I'm not sure are fixed in 3.2. Namely, you can't use setWhereClause() to set the entire where clause string from the client. You have to use setWhereClauseParams(). This means that you have to have the basic where clause included in the query and user parameters as placeholders for the where clause values. These are JSP methods, I'm not sure what the equivalent is in DAC, but I am pretty sure the same limitation is there.

How to execute a SELECT statement in java??

Hello !!
In my java program , i need to delete a record of number X, so
i accept the number X from the keyboard
Then before deleting it
i want the program to show me the name, age of the record which has the number X
How to do this

hello kylas
actually i didnt get why this program example?? wats
its executing ??? Look at reply #3 in your other thread:
http://forum.java.sun.com/thread.jspa?threadID=713289&messageID=4126346
Notice the similarity? You've now asked "How to delete a record in Java" and "how to execute a select statement in java". You may have noticed that, aside from the SQL and the call to execute and executeUpdate (for delete) it's the same code. This is because you don't so much do these things in Java, you do them in SQL. The Java code simply asks the Driver to execute whatever SQL you write. So, I really hope your next post isn't "how do I execute an UPDATE statement in Java".

Seems like you want to convert a SQL statement from the ??? dialect to the Oracle dialect. *(It would be useful to indicate the non-ANSI standard SQL you are starting with.)
Part of the problem is that you use several date related functions. Some are unnecessary in Oracle and some need to translated into Oracle functions as found in the Functions section (chapter 5) of the SQL Reference manual at http://www.oracle.com/pls/db102/homepage
Note that columns and expressions of type 'date' in ORacle always contain all of "yyyy mm dd hh mi ss" and you need to format and trauncate as necessary.
Also note that '09-JAN-31' is NOT an Oracle date, but rather a character representation of a date which must be converted to/from a date expression. You will often need to use the to_date() and to_char() functions with a format mask as the second parameter. This is also descreibed in the first 2 chapters of the SQL Reference manual.

Thanks for the reply.

Getting error while executing this select statement

Hi All,
I am new to this community.
I am getting error whie compiling the below code. Its telling 'Text' is invalid identifier. Also i want to know how can we obtain 'parseable' version of the below query?
my basic intention is to create a trigger header through a select statement and show it the complete text as a single column..
select text from
(select 'CREATE OR REPLACE TRIGGER '||SUBSTR(column_name,2,4)||'aud
AFTER INSERT
OR UPDATE
OF '||column_name||',
OR DELETE ON '||table_name||'
FOR EACH ROW'
FROM(SELECT lower(REPLACE(column_name,'O_','')) column_name , /*changing O to O_*/
lower(replace(t.table_name,'_A_','_')) table_name,
lower(t.table_name) table_name1,
c.column_id
FROM all_tab_columns c,
(SELECT object_name table_name
FROM all_objects
WHERE object_name LIKE '%/_A/_%' ESCAPE '/') t
WHERE c.table_name(+) = t.table_name
AND SUBSTR(column_name(+),1,2) = 'O_'))

thanks prathamesh. it solved the problem. i have one more question.
as of now it creates single create trigger statement for each column on a table.
example:
CREATE OR REPLACE TRIGGER ust_aud
AFTER INSERT
OR UPDATE
OF cust_id,
OR DELETE ON characteristic_t
FOR EACH ROW
however, i want to create trigger for all columns in a single statement. can you please help me how to do it?
basically want to 'CREATE TRIGGER' for all columns in a table. i am finding difficult how to change my query to suit this!!
i am pasting my original query again for your reference. pls advise...
example:
CREATE OR REPLACE TRIGGER ust_aud
AFTER INSERT
OR UPDATE
OF cust_id,
fixed_item_val,
copy_item_val,
rgn_id,
txn_id,
OR DELETE ON characteristic_t
FOR EACH ROW
ORIGINAL QUERY
select text from
(select 'CREATE OR REPLACE TRIGGER '||SUBSTR(column_name,2,4)||'aud
AFTER INSERT
OR UPDATE
OF '||column_name||',
OR DELETE ON '||table_name||'
FOR EACH ROW' text
FROM(SELECT lower(REPLACE(column_name,'O_','')) column_name , /*changing O to O_*/
lower(replace(t.table_name,'_A_','_')) table_name,

How to execute multiple sql statements in oracle?

I want to execute multiple statements in a single transaction in oracle. Following are my queries:
Create table temp_table as Select * from table;
SELECT * FROM temp_table d;
drop table temp_table ;
I am using sql comment text in asp.net
I am using executenonquery command in asp.net.
Thanks,
Divya

SigCle ,
Here's an example that executes 3 statements;
begin insert into foo values(1); insert into foo values(2); insert into foo values(3); end;
923354,
The block doesn't compile because temp_table doesn't exist at the point you're trying to compile the anonymous block. I'd recommend re-reading the doc link and forum link provided to get a better understanding of how temp tables work, as it's simply different with Oracle. You don't create Oracle temporary tables on the fly; you create them ahead of time and then just use them. The data itself is already specific to a particular session; you don't create and drop the table each time.
Also, you can't just "select * from table" in plsql. The results have to GO SOMEWHERE. Usually you'd either open a cursor and process it in the block, or send out a ref cursor if you want to send the data to a client side app. The ref cursor data wouldn't actually be fetched until the block completes though, so you'd need to use ON COMMIT PRESERVE ROWS, which would also mean you'd need to clean up the data yourself (delete the data from the table when you're done with it).
Corrections/comments welcome.

Whatever editor you are comfortable with. I assume there is one.
btw if there are a lot of INSERT statements in the script it might be worth adding the following to the top:

Output of value returned from function in SELECT statement ??

Hi
I have created the below function
create or replace
FUNCTION jc_test
RETURN VARCHAR2
IS myrec VARCHAR2(270);
BEGIN
SELECT RPAD('*',270,'*')
INTO myrec
FROM DUAL ;
RETURN myrec;
END ;
and I executed the SELECT statement in Oracle SQL developer as a script
select

I get exact output as below
LEN REC

So here LEN is correctly shown as 270 characters but when I see the astrisk's (also appended with spaces ) its total length is 4000 characters
Can anyone give their thoughts on this.
Its fine if I run as normal, i mean not as a script.

Table or view does not exists error while executing select statement

Hi,
I am new to Oracle. I am getting a error while executing the select statement if i give table name without double quotes.
Ex: Select * from Customer;
But working fine when the table name is enclosed within a double quotes.
Ex: Select * from "Customer";
Is there any way to execute the select statement without the double quotes?
Actually I am using NHibernate objects for data access.
Thanks,
Sai

Actually I am using NHibernate objects for data access.And probably that's the problem:
SQL> select * from mytab;
         A
         1
SQL> select * from mYtAb;
         A
         1
SQL> select * from MYTAB;
         A
         1
SQL> select * from MYTAb;
         A
         1Oracle statements are case insensitive and doesn't require double quotes unless the object names are reserved words.
As wrote by others if table is created using double quotes it's name bacomes case-sensitive... and this could be the problem...

VC & Oracle (Select Statement )

Dear All
I have implemented a feedback form in my Portal and the data which the portal gets is saved in oracle database .
Now my problem is i want to show the Admin of the portal what feed back we got
So I want to fire a select statement into oracle database but i don't know how to do that.
Can any one tell me how to get the result of select statement in VC from oracle database
Regards
Krishan

krishan,
You should define your database in the Portal and give it an alias.
You will have to use the JDBC connector.
After doing so you will have to create a stored procedure to select your data from the Oracle DB.
You will be able to access the oracle DB from the vsual composer by means of Stored procedure.
Please get back to me if you need more help.

In most cases this is something you should not be doing on a regular basis. Also when using dynamic sql, take care to use bind variables.

ORA-00911: invalid character using multiple select statements

I am getting an ORA-00911: invalid character error when trying to execute 2 select statements using ODP.NET.
cmd.CommandText = "select sysdate from dual;select sysdate from dual;";
cmd.Connection = conn;
cmd.CommandType = System.Data.CommandType.Text;
conn.Open();
OracleDataReader dr = cmd.ExecuteReader();
This works in SQL server but for some reason it appears this does not work in Oracle?
If this is the case what is a vaiable workaround? Wrapping the 2 statements in a transaction?
Seems strange that you can't return multiple result sets using in-line sql statements.

Oracle doesn't support passing multiple statements like that, and this is unrelated to ODP.NET.

        using (OracleCommand cmd = new OracleCommand(strSql, con))
            cmd.Parameters.Add("refcur1", OracleDbType.RefCursor, ParameterDirection.Output);

Auto retry of select statements on failure

I have a IBM Message Broker message flow that accesses the database to fetch some data. following are the steps in a message flow. (similar pattern is there in other flows as well)
1) Parse the input message
2) Invoke a ESQL compute node that accesses the database. This uses DataDirect ODBC drivers to access the database.
3) process the data
4) Invoke an external Java class that also accesses the database. This Java class uses Spring/Hibernate and uses the Oracle UCP library.
Steps 2 and 4 access an Oracle database on which failover features are NOT enabled. Following is our observation.
If the database fails when executing step 2, then the message flow pauses until a valid connection is available and then proceeds with the execution, the point to note is that the message flow does not experience a failure. It simply pauses until it gets a connection and continues once it gets a connection.
If the database fails when executing step 4, the message flow gets an error.
What we want is for step 2 and 4 to execute the same way, meaning that we want the message flows to wait until a valid connection is available and then continue without any errors.
I feel that there is some feature in DataDirect driver that cause step 2 to pause the message flow and prevent an error. We want the same behaviour in step 4 as well.
So, is there some way (via configuration or any other means) to get this behaviour using oracle UCP library.
One thing to note is that we are not in position to change the Java code since it has been developed by a third party.
To achieve this I have written a test and the following are details.
For this I have created a service with the following properties. Point to note is that we run the service on only one instance at a time, if it goes down then it is started on the second instance.
Service name: LDL_TEST02
Service is enabled
Server pool: CSAHEDA_LDL_TEST02
Cardinality: 1
Disconnect: false
Service role: PRIMARY
Management policy: AUTOMATIC
DTP transaction: false
AQ HA notifications: true
Failover type: SELECT
Failover method: NONE
TAF failover retries: 180
TAF failover delay: 5
Connection Load Balancing Goal: LONG
Runtime Load Balancing Goal: NONE
TAF policy specification: BASIC
Edition:
Preferred instances: CSAHEDA1
Available instances: CSAHEDA2
Following is in my tnsnames.ora file and I am using the oracle oci driver.
TESTA =
(DESCRIPTION =
(ENABLE = BROKEN)
(LOAD_BALANCE = off)
(FAILOVER = on)
     (ADDRESS_LIST =
     (ADDRESS = (PROTOCOL = TCP)(HOST = vip.host1)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = vip.host2)(PORT = 1521)))
(CONNECT_DATA =
(SERVICE_NAME = LDL_TEST02)
(FAILOVER_MODE =
(BACKUP = TESTA2)
(TYPE = SELECT)
(METHOD = PRECONNECT)
(RETRIES = 120)
(DELAY = 5)
This is how I run my test.
1)I have a simple test that simply loops through a list of select statements.
2)each time it takes a connection from the connection pool, executes the statement and returns the connection to the connection pool.
3)I keep this running for around 10 minutes.
4) once the test has started I bring down the service wait for 3 minutes and the start the service on the second instance.
5) what I expect is for the test to pause for 3 minutes and then get the correct value from executing the select statement. and continue without pause.
Following is the config for the connection pool.

          <property name="connectionFactoryClassName" value="oracle.jdbc.xa.client.OracleXADataSource"/>
          
          
          
          
          
          
          <property name="URL" value="jdbc:oracle:oci:/@TESTA" />
          
          
          
          
          <property name="user" value="user" />
          <property name="password" value="user" />
          <property name="connectionPoolName" value="dd_connectionpool" />
          <property name="minPoolSize" value="2" />
          <property name="maxPoolSize" value="4" />
          <property name="initialPoolSize" value="2" />
          <property name="connectionWaitTimeout" value="10000" />
          
          <property name="validateConnectionOnBorrow" value="true"/>
          
          
          
          
     </bean>
As you can see I have tried many combinations.
Sometimes I see the thread pause for 3 minutes without error and then continue.
Sometime I start seeing 'oracle.ucp.UniversalConnectionPoolException: Cannot get Connection from Datasource' as soon as the servic is down.
Sometime the first error above is seen after 30 seconds (always the first one).
Can you guys shed any light on this? And how can I get the desired behaviour?
