Sql server 2000 stored procs vs. prepared statements performance

Hi
I have observed that using stored procedure in sql server 2000 is much much faster than using a prepared statements. I had worked with oracle before and did not notice this much difference. I would like to use prepared statements or regular sql (for dynamic sql creation) in my apps. Does anyone have any suggestions ?.
thanks

Hi
FYI
I figured out the slowness problem in using prepared statement (db - sql server 2000)was due to the Microsoft typ4 4 jdbc driver. When I used the jdbc driver from atinav, my prepared statements worked as fast as stored procs.

Store&read chinese characters in MS SQL server 2000 using Java

Hi,
I have a problem to store Chinese characters in MS SQL Server 2000, storing question marks(??????) instead of Chinese characters
I am using JSF framework, SUN APPLICATION Server 9.1 , MS SQL Server 2000 server and Microsoft data source driver class (com.microsoft.sqlserver.jdbc.SQLServerDataSource) to connect db.
I have one solution:
IN JSP:
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
and
In database column type should nvarchar in place of varchar
while inserting or updating the same need to add N prefix with the value like insert into client(Name, Id .) values (N+)
the above is working fine but the problem is here i have already defined database with 100s of tables I cant change database tables as well as queries
Thanks,
Sathi

I don't know any betterer option, than to copy the database tabels redefining the Chinese data fields as nvarchar.
To be frank I had also problems writing to a html file Chinese text stored in MS SQLServer 2000 nvarchar fields.
The following worked:'
     public String getEncodedData(ResultSet resultSet, int columnIndex, String charset)
     throws SQLException
          //final String methodName = "getEncodedData";
          InputStream binaryStream =resultSet.getBinaryStream(columnIndex);
          String readStringFromStream=readStringFromStream(binaryStream, charset);//UTF_16LE);
          return readStringFromStream;
     public String readStringFromStream(InputStream inputStream, String charset) {
          final String methodName = "readStringFromStream";
          StringBuffer buffer = new StringBuffer();
          try {
               int ch;
               InputStreamReader isr = new InputStreamReader(inputStream, charset);
               Reader in = new BufferedReader(isr);
               while ((ch = in.read()) > -1) {
                    buffer.append((char)ch);
               in.close();
               return buffer.toString();
          } catch (IOException exception) {
               Log.printError(this,methodName, exception);
               return null;
     }And writing it to file:
     public void writeEncodedStringToFile(String text, String filePath, String charset, boolean append){
          final String methodName = "writeEncodedStringToFile";
          OutputStreamWriter writer= null;
          try {
               FileOutputStream fileOutputStream = new FileOutputStream(filePath, append);
               writer = new OutputStreamWriter(fileOutputStream, charset);
               writer.write(text);
          } catch (IOException exception) {
               Log.printError(this,methodName, exception);
          }finally{
               try {
                    writer.close();
               } catch (IOException exception) {

Problem converting captured SQL Server 2000 database to Oracle

Java(TM) Platform     1.6.0_17
Oracle IDE     2.1.1.64.45
Versioning Support     2.1.1.64.45
After creating MWREP user, granting it privileges and creating the migration repository, I have captured a small SQL Server 2000 database (1 table), but after performing "Convert to Oracle", I get the message that it has transformed correctly, but no converted model is shown. I was originally using the JRE supplied with SQL Developer 2.1.1, but replaced that with 1.6 U17 after researching the problem here.
The only message in the Migration Log is as follows:
Catalog RAC, Schema dbo coalesced to single schema dbo_RAC
The following message appears in the console:
SELECT DISTINCT(REF_ID_FK), REF_TYPE FROM MD_ADDITIONAL_PROPERTIES WHERE PROP_KEY IN (?) AND CONNECTION_ID_FK = ?
I have tried this with a more complex database, with no luck.
Any thoughts?

I did an offline capture.
I used Tools->Migration->Third Party Database Offline Capture->Create Database Capture Scripts to generate scripts OMWB_OFFLINE_CAPTURE.BAT, SS2K_BCP_SCRIPT.BAT and sqlserver2000.ocp. Then the SQL Server DBA ran OMWB_OFFLINE_CAPTURE.BAT and sent me the output.
I used Tools->Migration->Third Party Database Offline Capture->Load Database Capture Scripts Output to capture the model into the repository successfully.

Callable Statement + SQL Server 2000

I am using the Microsoft SQl Server 2000 JDBC driver and a CallableStatement (Java). The call is to a (SELECT action) stored procedure which works fine in Query Manager with the same login params. I am getting a "Could not find stored procedure" error?? I am using the fully qualified procedure name. I have looked on TechNet for this type problem but to no avail.
Thanks

WL 6.0 using MS SQL Server 2000 - Transaction timeout when invoking stored procedure

Hi,
Facing a problem on WL6.0. We are connecting to MS SQL server 2000 using a stateless
session bean
using container managed transaction. The bean method does a few updates to the
database and also
calls a stored procedure that generates primary keys many times. This stored procedure
(SP) is running
in a transaction of its own since it has to increment a counter, update the database
and then return the
primary key.The primary key generator SP is working fine and does not lock the
database in many bean
methods.
In some methods we find that the primary key generator SP has locked the database.
We
then see a lock on the database created due to this SP in the MS SQL client. The
execution goes
into the SP and gets stuck there till the bean's transaction times out. The error
message given is

Batch statement with sql server 2000 driver

Hi,
I have been using the jdbc bridge and recently upgraded to the sql server 2000 driver. I have some code that was working correctly executing some batch commands. But with the new driver it no longer works. Its throwing errors. Can anyone help? I have tried removing the begin/end statments and that causes a different error to be thrown.
Statement s = db.createStatement();
s.addBatch("Begin");
s.addBatch("use master");
s.addBatch("EXEC sp_addlogin '" + login +"','" + loginAuth + "','testDB'");
s.addBatch("use testDB");
s.addBatch("EXEC sp_grantdbaccess '" + login + "' , '" + login + "'");
s.addBatch("End");
s.executeBatch();

I have been using the jdbc bridge and recently
upgraded to the sql server 2000 driver. i think you maybe are sol...
Statement s = db.createStatement();
s.addBatch("Begin");
s.addBatch("use master");
s.addBatch("EXEC sp_addlogin '" +
p_addlogin '" + login +"','" + loginAuth +

s.addBatch("use testDB");
s.addBatch("EXEC sp_grantdbaccess '" +

s.addBatch("End");
s.executeBatch();the documentation from microsoft reads...
for both CallableStatement and PreparedStatement
void addBatch (String)
Not Supported

is this the error you are seeing?

Storing Unicode data in SQL Server 2000

hello,
I'm currently developing a website which must store Cyrillic characters in a SQL Server 2000 database. I know the database can store the data correctly because when I use the MS Front end to connect to the database I am able to copy/paste the text into the database columns correctly.
Retrieving the data from the database also works correctly and is displayed with the correct characters.
The problems I am having is that the text seems to get garbled during the SQL insert by the database driver. If I print out the SQL just before it is inserted the characters are still correct but once they get into the database they are wrong. I'm using the JDBC drive to connect to the database.
Any help would be appreciated,
Alan

I change the way I was storing the data from using unicode to getting the char values of each letter (ie \u1041 for Б) and storing them in the database. Then I parse the numbers when I bring them back out and combine them into the original String

Can I pass an array as an input parameter for a stored procedure on SQL Server 2000

I am trying to pass an array to a stored procedure residing on my SQL Server 2000 database server. Is this even possible? If it is possible, what is the syntax for this?
Any help would be greatly appreciated.
Thanks

I have passed arrays to and from a database using SQL and ActiveX, including to and from stored procedures, but I cannot recall the precise method used to do so. If memory serves, everything is in the form of a string. You need to do a lot of parsing and 'unparsing' to get this data into your stored procedure.
You are left with a couple of options to get your data to the stored procedure. I recommend using SQL in LabVIEW wherever possible as it saves the amount of external code calls (and believe me, calling ActiveX procedures developed by someone else in Visual Basic is NOT much fun at all...). You can either send the array and other data to the stored procedure (you will find the syntax in the SQL references in LabVIEW help under SQL), or you can send
the array to the database, and have the database then act upon the array.
I strongly recommend making routines (subVIs) to handle these operations.
Sorry I don't have the syntax, I don't have SQL installed on this machine. If you can't find the syntax in the help, please post here again.

Storing and retrieving arabic in SQL Server 2000

hello, i realize this problem has been posted lots before but i read in the forum and i couldn't find a solution to fix my problem
i am developing a desktop application in java and sql server 2000, and i'm using JBuilder for writing my java codes
here's the problem
i can MANUALLY store arabic text in my database (directly in SQL Sever Query Analyzer) and can read it in arabic properly in SQL Server, but if i want to retrieve the arabic text in a query in JAVA, for example: select * from person i see weird characters (not question marks) but not the original arabic text
and if i type arabic text in a java textfield and use the value entered in an sql query, for example:
sqlQuery = "insert into person (fname) values ('" + jtfFName.getText() + "')";it is inserted in SQL Server as ?????s and when i retrieve the values from the table i also see it as ?????s
even when i converted all the data types in the database to unicode data types (*nchar* instead of char and nvarchar instead of varchar) and modified the sql query to the following:
sqlQuery = "insert into person (fname) values (N'" + jtfFName.getText() + "')";(N outside the single quotation mark since according to rules on msdn)
it still didn't solve the problem
please i need urgent help with this issue!

problem was solved by setting the charSet encoding to "UTF-8" in the connection to sql server using the jdbc-odbc bridge

Problem with Sensitive ResultSet in SQL Server 2000

Hi,
I am trying to use SCROLL_SENSITIVE and CONCUR_UPDATABLE ResultSet accessing SQL Server 2000. I am using JDK 1.3 and supported JDBC driver. When I tried to insert a row, I got the following message:
sp_cursor: The cursor identifier value provided (0) is not valid
Is there any setting in SQL Server that I need to configure or do I miss something in my code?
Thanks,
Andi Setiyadi
Here are my codes:
cs = connection.prepareCall("{call sp_deptInfo (?,?,?)}", ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
cs.setInt(1, 0);
cs.setString(2, "");
cs.setString(3, "name/orderbyid");
rs = cs.executeQuery();
rs.last();
int rows = rs.getRow();
rs.afterLast();
rs.moveToInsertRow();
rs.updateInt(1, rows + 1);
rs.updateInt(2, Integer.parseInt(parentDept));
rs.updateString(3, newDept);
rs.updateInt(4, 1);
rs.insertRow();

I am getting the resultset by calling a stored procedure. I am not changing the stored procedure itself.Database drivers create 'connections' and 'statements' which match the SQL that you pass it. You are passing it a stored proc. The only information that it has is on a stored proc. It doesn't matter where the stored proc got its info from. The stored proc doesn't return tables and indexes into tables. It returns a result set (that is what your code suggests.) That is all the information that the driver has.
Consider your stored proc might return this
select * from mytable where ....
But it could also do this
select 'value1', 'value2', ... from dual
On the java side it isn't not going to know which of the above that you did. Nor should it. And you can't update/insert into that second example.
Or at least that is how I look at it.
Your code looks like it is trying to 'update' the result set that a stored proc returned. And I simply don't see how that is possible. Or even why anyone would want to do it.

I'm thinking if any one of you is able to access an SAP system on SQL Server (2005 or other) with the above mentioned stored procedure present you could scipt it to a txt file and post it here in order for me to create it manually on my system.
I've checked several SAP Notes on this subject and none of them explains how to create this store procedure from scratch, they all just assume it's already there and tell you to execute it.
Thank you.

Query Perofmance is much more fast in SQL server 2000 than Oracle 9i

I have converted a database from SQL Server 2000 to Oracle (9.0.2).
In a stored procedure a query based on 4 tables working well in SQL Server which takes just 1 or 2 minutes to give result But in Oracle it takes 3 to 4 Hours to return the results.Although Database hit ratio is 99 plus %. In Oracle when i created indexes on 2 columns of 2 tables it just take 5 to 10 sec. But I want to get the result in less time without indexes. Because in
SQL Server it Works well without indexes.
Please reply me with some solutions or reasons
Regards
AN

Most sites have a job that runs every night to keep the statistics up to date.Really? I would be very surprised if that was the case. Firstly, many sites don't want to take the hit of running stats for a whole system each night. Secondly, I would hope that many DBAs know this statement...
Always keep up to date statistics if you want your database to be efficent. ...is wrong.
The best that can happen from refreshing the statistics every night is that it makes no difference to your application. If your application is running nicely - that is, no users are yelling at you - then your current statistics are good enough. Refreshing statistics introduces instability into the system and might lead to queries performing worse than before.
Gathering stats is not the sort of thing you want to do with a scattergun. Analyze your database once, after you've reached what is a representative data volume and then leave it alone. Only refresh statistics if you have a specific issue (user complaint) and you think stale statistics might be the cause.

DTS Import of MDB in SQL Server 2000 Drops Memo Field Data

I have used DTS in SQL Server 2000 to import an MDB filed (MS ACCESS) of a table. When the table is imported the primary key is lost and the memo field data is completely gone.
I use the tranformation option in the DTS wizard to add the primary key and make sure the data type for the memo field is varchar and has a size of 8000. I need that large size since I am storing lots of html code.
When I preview the data I see the html code that is supposed to get imported. However, when I return all rows from the table in Enterprise Manager the field is empty.
So I tried to manually copy the data from the MS Access Database into SQL Server. Could not figure out if SQL Server has an interface like MS Access to simply copy data into a table. So I linked to the tables from MS Access to the SQL Server table.
When I opened the linked table I see the data in the description field. However, if I return the rows from within SQL Server no data is present.
I have some ASP code trying to read the data in the SQL Server table. However, nothing is returned and when I run the SQL Statement, nothing gets returned. The SQL statement returns all rows. All the other data is present but nothing in the description field.
What am I doing wrong? Any suggestions anyone, please!
TIA

It is important to know the version of MS Access. I will recomend you to use nvarchar datatype instead of varchar. May be the description field contain unicode characters.
Refer this link to understand more on datatype mapping between access source and sql server destionation.

Converting SQL Server 2000 to Oracle 9i

Hi,
I am working on the migration of stored procs from a SQL Server 2000 database to Oracle 9i. The sqlsrvr db contains 75 relatively complex procs using temporary tables to create intermediate resultsets for further processing.
The Oracle 9i environment has very strictly standards and temporary tables are not allowed.
Is it standard practice to use PL/SQL tables to simulate the functionality of temp tables?
I understand you can now use SQL against PL/SQL tables under certain circumstances.
I would envisage using the PL/SQL tables in multi-table joins with schema tables.
Any ideas whether I am going down the wrong path.
Thanks in advance,
Garrett Donnelly

Garrett,
Note that there is also an parser option to 'Generate8i temp tables', where the data in the permanent tables is seperated from other sessions by the use of an extra Session id colum.
Please post the results of your PL/SQL table experiences.

Turloch

Connecting Oracle 9i as a linked server of SQL Server 2000

I have a problem inserting String values into Oracle 9i as a linked server or SQL Server 2000.
When I run the following in SQL Analyzer:
insert into ORACLEOLE..ADMIN.FM_SQL values('asdf','qwer');
The result msg is:
Server: Msg 7356, Level 16, State 1, Line 1
OLE DB provider 'OraOLEDB.Oracle' supplied inconsistent metadata for a column. Metadata information was changed at execution time.
OLE DB error trace [Non-interface error: Column 'FM_ID' (compile-time ordinal 1) of object '"ADMIN"."FM_SQL"' was reported to have a DBTYPE of 129 at compile time and 130 at run time].
Is this a problem that the Charaterset of Oracle 9i being 'ALU32UTF8' ?
I have tried changing the field's type to varchar2, char, nvarchar2 and nchar...and they didn't work.
However, when the field type is a number(10) and I insert to the table integer values, the sql works fine.
so..any data mapping need to be done explicitly?
Thanks in advance.

Based on my reading of the ANSI SQL-92 standards, table names are supposed to be in upper case.
"of course, any lower case letters appearing in a <regular identifier> will have been converted to the corresponding upper case letter before the <identifier> is stored in any table of the Information Schema"
http://www.contrib.andrew.cmu.edu/~shadow/sql/sql1992.txt
Given that table names are supposed to be in upper case and they are in fact in upper case, why don't you just ask for them in upper case in the first place?
