Prepared Statements and Oracle functions:

Consider this code:
String searchText = "someInputText";
StringBuffer sqlstmt = new StringBuffer();
sqlstmt.append("SELECT ID_FIELD FROM ");
sqlstmt.append("MY_TABLE WHERE NAME_FIELD ");
sqlstmt.append("like INITCAP('%" + searchText + %')");
PreparedStatement ps = con.prepareStatement(sqlstmt.toString());This works fine like this, but when I replace the searchText in the sqlstmt to ? it doesn't work:
sqlstmt.append("like INITCAP('?')");
PreparedStatement ps = con.prepareStatement(sqlstmt.toString());
ps.setString(1, "%" + searchText + "%");How do you use the PreparedStatement with a
function like INITCAP where you need to use a
dynamic ? in the sql statement?
Thanks,
Rob.

Very easy to miss this.
Don't put the percentages IN the SQL statement.
Append the percentages to your string.
Like this:
String searchText = "%" + "someInputText" + "%";
StringBuffer sqlstmt = new StringBuffer();
sqlstmt.append("SELECT ID_FIELD FROM ")
.append("MY_TABLE WHERE NAME_FIELD ")
.append("like INITCAP(?)");
PreparedStatement ps = con.prepareStatement(sqlstmt.toString());
ps.setString(1, searchText);
resultSet = ps.executeQuery();Wish I saw this earlier for you.

Statement,Prepared Statement and callable statement

Hi,
Please let me know in which scenario we are using Statement,Prepared Statement and callable statement.
and which is efficient one among the above.
Thanks in advance

We don't know what scenario you are using those in or if you are using them at all. Are you asking what they are?
For document related questions you should consult the documentation or use your favorite search engine to get information.
See the Java Tutorial

The main feature of a PreparedStatement object is that, unlike a Statement object, it is given a SQL statement when it is created. The advantage to this is that in most cases, this SQL statement is sent to the DBMS right away, where it is compiled. As a result, the PreparedStatement object contains not just a SQL statement, but a SQL statement that has been precompiled. This means that when the PreparedStatement is executed, the DBMS can just run the PreparedStatement SQL statement without having to compile it first.

The Javadocs for your Java SDK have the API for each of those classes and a description of what they are. And the Oracle JDBC Developer Guide has extensive information on how to use them.

Case statement and Decode function both are not working in Select cursor.

I have tried both the Case statement and Decode function in Select cursor, but both the things are not working. On the other hand both the things work in just select statement.
See the first column in select (PAR_FLAG), I need to have this evaluated along with other fields. Can you please suggest some thing to make this work. And also I would like to
know the reason why decode is not working, I heard some where Case statement do not work with 8i.

Pooling Prepared Statement and Resultset

Is their any mechanism in Weblogic by which we can pool prepared statements and
resultset.

Yes you can cache prepared statements. The connection pool will
automatically cache the prepared statements (10 prepared statement was the
limit in previous so you may want to write some startup class to load the
imp prepared statements.). When you reuse the prepared statement the
connection pool will pick it from its prepared statement cache. In 6.1 you
can configure the number of prepared statements that you want to cache.
But you cannot have multiple resultsets open for the same statement object.
You can have cache rows though.
Please search the bea newsgroups for more info. There are a bunch of posts
that will be helpful to you.

MS SQL Server 7 - Performance of Prepared Statements and Stored Procedures

Hello All,
Our team is currently tuning an application running on WL 5.1 SP 10 with a MS
SQL Server 7 DB that it accesses via the WebLogic jConnect drivers. The application
uses Prepared Statements for all types of database operations (selects, updates,
inserts, etc.) and we have noticed that a great deal of the DB host's resources
are consumed by the parsing of these statements. Our thought was to convert many
of these Prepared Statements to Stored Procedures with the idea that the parsing
overhead would be eliminated. In spite of all this, I have read that because
of the way that the jConnect drivers are implemented for MS SQL Server, Prepared
Statments are actually SLOWER than straight SQL because of the way that parameter
values are converted. Does this also apply to Stored Procedures??? If anyone
can give me an answer, it would be greatly appreciated.
Thanks in advance!

Thanks in advance!Hi. Stored procedures may help, but you can also try MS's new free type-4
driver,
which does use DBMS optimizations to make PreparedStatements run faster.
Joe
Thanks Joe! I also wanted to know if setting the statement cache (assuming that
this feature is available in WL 5.1 SP 10) will give a boost for both Prepared Statements
and stored procs called via Callable Statements. Pretty much all of the Prepared
Statements that we are replacing are executed from entity bean transactions.
Thanks again

LINQ Canonical Functions and Oracle Functions

Hello,
I am using EntityFramework (.NET 4) to access a Oracle Database (11g Express Edition Release 11.2.0.2.0 - 64bit Production).
For the most part it is working fine, but now I've stumble into a issue using LINQ Canonical Functions, that aparently are supported (see : Mapping LINQ Canonical Functions and Oracle Functions)
I am running the following expression :
var expirationDuration = 3000;
var record = Context.Table
.Where(x => x.Created.AddMilliseconds(expirationDuration) > DateTime.Now )
.FirstOrDefault();
And im getting a exception :
"LINQ to Entities does not recognize the method 'System.DateTime AddMilliseconds(Double)' method, and this method cannot be translated into a store expression."
Shouldn't AddMilliseconds be translated to (expression) + INTERVAL like the docs mentions?
Thanks for help
Regards,Nuno

Neither ODP.NET nor SQLClient recognizes System.DateTime AddMilliseconds(Double) method as a valid method
I would suggest you use EntityFunctions AddMilliseconds instead.

What is the difference between Open-Script and Oracle functional testing

Hi All,
Please help me in spotting out the difference between the Openscript and Oracle Functional Testing for Web Application.
Does Oracle Functional Testing for Web Application have any special features when compared with Open-Script.
Please help me out.
Thanks in Advance,
Nishanth Soundararajan.

Nishanth
OFT is the old version of OpenScript, which will no longer be part of ATS as per the next major realize 9.20.
I would recommend to to spend any time looking at it.

Oracle Prepared Statement and spaces in field

I have a field that is defined as char(10). It has characters like '39' in it. When I select against it using standard SQL (where clause) I get results. When I use it in the where clause of a prepared statement it does not return any rows.
If I have the field defined as char(2) the prepared statement works.
If I have the field defined as varchar2(10) and loaded with '39' the prepared statement works.
If I have the field defined as varchar2(10) and loaded with '39 ' the prepared statement returns no results.
I really do not think this is a JDBC problem. However, since Oracle's site basically <expletive deleted>, I am hoping someone here has a solution.
Thanks in advance if you can help.

Let me clarify.
I cannot remove the whitespace from the data in the database. I do not need the whitespace to do the query if I am not using a Prepared Statement. This seems to be a problem with the way Oracle is handling the prepared statement. (hence.. my thinking that this is really not a JDBC problem at all.. but I could be wrong.)

Prepared statement cache & Oracle

Hi -
Does Weblogic's prepared statement caching only work when using their
type-2 Oracle driver? Are there any documents about using this
Weblogic feature? I have only found small references in the Weblogic
documentation so far -- nothing with much detail.

Do you know if each connection's cache is FIFO? Or do you use
least-recently-used algorithm?
I found one comment you made regarding XA pools. That means that if we are
doing 2-phase commit processing that some of these benefits could erode? I
didn't understand why. If we assume that the connections in a given pool
after a time get a good sampling of popular prepared statements, would their
being XA or not matter? Maybe I missed your point entirely.

Prepared Statement and DEFAULT identifier

Does anyone know how to pass the identifier DEFAULT to a PreparedStatement?
I am processing a text file to import into a database table (Oracle 9i) via JDBC. The user is able to configure what will happen if the data in the file doesn't match the types required by the database and so I do a quick check that the data is of the right type before it gets to the database. The user can choose to have the invalid value replaced with the default associated with that field (as configured on the database table). Eg. Table setup is
CREATE TABLE "TEST1" (
"TESTFIELD1" VARCHAR2(40 byte),
"TESTFIELD2" VARCHAR2(40 byte) NOT NULL,
"TESTFIELD3" NUMBER(30, 10) DEFAULT 777)
sample data of 'abc', 'def', 'www' should therefore end up as 'abc', 'def', 777
The problem I have is that I'm using a PreparedStatement to do the INSERTs (there could potentially be thousands of them).
The following SQL is what I'm trying to emulate...
INSERT INTO table (field1, field2, field3) VALUES ('abc', 'def', DEFAULT);
BUT, I am using a PreparedStatment via JDBC with bind variables ...
pstmt = con.prepareStatement("INSERT INTO table (field1, field2, field3) VALUES (?, ?, ?)");
ps.setString(1, "abc");
ps.setString(2, "def");
ps.setsomething(3, something); <- what goes here?
I have no idea what to put in the "something" bits so that DEFAULT is passed through. I obviously can't use setString(3, "DEFAULT"); as I'll just get an Oracle type mismatch error.
I realise that I could just leave out the 3rd variable and the default would be inserted automatically - but because some of the rows in the input file may have a valid value for field3 I don't always want the default value. Using the straight SQL is not an option due to the performance (or lack thereof).
Any ideas would be greatly appreciated! Thanks!

As for the best of my knowledge if you set the value to be null in the prepared Statement while setting that
for insert statement internally it is set to DEFAULT in ORACLE..
More over i thought that this will be usefull for u..
setNull
public void setNull(int paramIndex,
int sqlType,
String typeName)
throws SQLExceptionSets the designated parameter to SQL NULL. This version of the method setNull should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.
setNull
public void setNull(int parameterIndex,
int sqlType)
throws SQLExceptionSets the designated parameter to SQL NULL.
Note: You must specify the parameter's SQL type.
Parameters:
parameterIndex - the first parameter is 1, the second is 2, ...
sqlType - the SQL type code defined in java.sql.Types
Throws:
SQLException - if a database access error occurs

Prepared Statement and Stored Procedure difference?

For SQL in my web applications I use PreparedStatement object alot in my JDBC working with Oracle 9i.
I also heard the term Stored Procedure. What is the difference between Stored Procedure and Prepared Statement?

I am new to java programming, can anybody explain
what exactly precompiled means
Thank you
PalspaceWhat does you subject line have to do with your question?
The difference between a stored proc and a prepared statement is mainly this.
A stored proc is stored in the database server permanently and can be used and re-used from a different connections.
A PreparedStatement is not valid across connections.
Stored procs are almost always precompiled. (I am just hedging a bit here just in case but you can consider it 100%)
PreparedStatements MAY be precompiled. Hard to say.
Precompiling means at least one of and perhaps all of the following depending on the database
- The parsing of the SQL statement
- The checking of the SQL against the data dictionary to ensure that the tables and columns referenced actually exist
- The preparation of a query plan
Last but not least Stored procedures may (and often do) contain more than simple queries but are in fact relatively complex programs written in a DB specific language (an offshoot of SQL of some sort).

user539085,
I guess it returns 0 (zero) because it doesn't delete anything. Can you verify that it did delete some records and still returned zero?
Good Luck,
Avi.

Prepared Statement and Stored Procedure..

I have about 200 SQL statement in my Java application
I have two options either to convert into
Stored procedures
or to convert into prepared statement ....
Please guide me which options should be best....
I need difference
1)in term of speed.
2)Memory..

club your statements on the basis of related functionalities and change it to stored procedures as it will redudce no. of calls to the database and will be faster to fetch data in one go and even reduce the memory requirements.

Regarding case statement and decode function

Hi Experts,
I have question.....regarding case statement and decode statement....
Can you please explain me that which one will be efficient,to place in insert statement...
insert statement(
(case when ........then
                     case when ....then
                     else
                     end)
else
end)
or
insert statement(
case when.....then
decode(....)
else
end)
Can you people explain me which one is more efficient method?
Thanks in advance.......

The are major differences to talk about in case of CASE vs DECODE, but performance wise both are pretty much the same.
Have a look at Tom's thread
Ask Tom &quot;better performance - case or decode&quot;
I would suggest to use CASE whenever possible. Don't worry about the performance part.

Oracle Prepared Statement - 8.1.7 JDBC type II Driver

Hi,
I have a strange problem.
I do a query using a prepared statement and there are no matching results.
I change this to hardcoded SQL Statement and pass in the same value a row of record is returned
I change this to Statement and pass in the input a row of record is returned.
This is puzzling. There seems to be a problem with Prepared Statement and I can't see why that fails.
The Stmt looks like this
PreparedStatement id is defiend as a char in the database
Code Snippet:
SQL = Select * from employee where id = ?;
pstmt.setString(1,'value');
Hardcoded SQL:
select * from employee where id = 'value';
Statement Impl:
String var = "value";
"select * from employee where id = '" + var+ "'";
Would appreciate if somebody can explain what's happening. To me it is bizarre!
Thanks,
Manglu

Update to problem
I have the latest (classes12.zip) JDBC drivers from Oracle.
We are running Oracle 8.1.6 and converting to Oracle 8.1.7.
This works the same with both.
Example, I have a column (char(10)) with trailing spaces. i.e. '39 '.
When I perform a Prepared Statement with that column in the where clause, it returns no result rows.
When I perform a standard statement with that column in the where clause, it returns rows.
When I define a column char(2) and use it in the where clause it works fine.
When I define a column varchar2(10) and load it with data like '39', it works fine.
When I define a column varchar2(10 and load it with data like '39 ', it does not work.
When I execute this same Prepared Statement through the jdbc:odbc bridge it works fine.
I cannot change the definition of the columns as they are foreign key data. What is the problem here? Any help is appreciated.
If you need further information please feel free to contact me.
