How to insert a CLOB in Oracle8.0 with JDBC

Hi,
I'm having trouble to insert a CLOB into a table with java. I'm using JDK1.1.8 and Oracle8.0
I've to insert more 4000 char String into that field. What can I do? Any example is very appreciate.

This is a problem with the driver. It is a known bug/issue.
You have to use the dbms_lob.write procedure and append data to the clob inside a loop.
i.e. do something like (pseudo-code)
while(file.not_end)
char[] buffer= file.read(start_pos,bytes_read);
dmbs_lob.write(buffer);
start_pos = start_pos+ bytes_read;
null

How to insert some strings in a query with the clausule 'in' in a procedure

Hello fellows.
Do you know how to insert some strings in a query with the clausule 'in' in a procedure (with a variable)?.
I tell us my problem with an example:
I want to use this select but introducing a variable instead the 'value1', 'value2':
select * from table1 where field1 in ('value1', 'value2');
if I declare the variable var1 as:
TC_VAR1 CONSTANT VARCHAR2(50) := '''value1'',''value2'''
and I use it as:
select * from table1 where field1 in (TC_VAR1);
It doesn't work because Oracle takes TC_VAR1 as an all string. I think Oracle takes it as this:
select * from table1 where field1 in ('value1, value2');
If I use the data type TABLE, I don't know how to use well:
TYPE varchar2_table IS TABLE OF VARCHAR2(10);
tb_var varchar2_table;
select * from table1 where field1 in (tb_var);->It returns an error and there ins't an method that it returns all values.
A curious case is that if I have a sql script (for example script1.sh) with this query:
select * fromt able1 where field1 in (&1)
and I invoke this script as
script1.sh "'''value1'',''value2'''". It works
Can anybody helps me?.
Thanks.

Thanks to all. Really.
First, sorry for my English. It's horrible. Thank to all for understand it (my English).
I've resolved my problem with these links:
ORA-22905: cannot access rows from a non-nested table item
and
http://stackoverflow.com/questions/896356/oracle-error-ora-22905-cannot-access-rows-from-a-non-nested-table-item
At last, I have used someting like this:
DECLARE
number_table_tmp NUM_ARRAY:=NUM_ARRAY(410673, 414303, 414454, 413977, 414042, 414115, 413972, 414104, 414062);
BEGIN
FOR c1 IN (SELECT par_id, 1 acc_vdo_id FROM SIG_VIS_CAM
WHERE par_id IN (SELECT * FROM TABLE(number_table_tmp))
UNION ALL
SELECT par_id, 2 acc_vdo_id FROM SIG_ACCAO a
WHERE par_id IN (SELECT * FROM TABLE(number_table_tmp))) LOOP
NULL;
END LOOP;
END;
but first I had to create the type NUM_ARRAY like this:
CREATE TYPE subjectid_tab AS TABLE OF NUMBER INDEX BY binary_integer;
THANK YOU, GUYS. YOU ARE THE BESTS. ;-)

Once you've configured the external content type, you can interact with it using the BDC Object Models available to you. You can use server side or client side and interact with the database without an external list.

Exception in thread "main"

First off, use the '-primaryKeyOnJoin true' flag when running the reverse
mapping tool so that you can get rid of that useless Xref class and have
a direct relation between Person and Project. See the documentation on
reverse mapping tool options here:
http://www.solarmetric.com/Software/Documentation/latest/docs/ref_guide_pc_reverse.html
But your real problem is that you are creating new objects, assigning
primary key values, and expecting them to represent existing objects.
That's not the way JDO works. If you want to set relations to existing
objects in JDO, you use the PM to look up those objects. If you try to
create new objects, JDO will assume you want to insert new records into
the DB, and you'll get PK conflicts like you see here.
There are several good books out on JDO; if you're just starting out with
it, they might save you a lot of time and help you master JDO quickly.

How to insert/update Date field in Oracle with java code

Dear All
I have to insert/update a date column while creating a new item, but the problem is i am able to insert/update only date but i need both date and time along with AM/PM.
By using these 3 lines i am able to insert/update only date.
java.util.Date date = new java.util.Date();
long dateLong = date.getTime();
stmtPrep.setDate(33, new java.sql.Date(dateLong));
Below code retrives the date exactly what i need but unable to pass in the statement:
DateFormat formatter = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss a");
java.util.Date d = (Date) new java.util.Date();
String stringdate = formatter.format(d);
String tmpdate = dateFormat();
stmtPrep.setString(33, tmpdate); -- I tried with setObject as well but same error coming.
Error is:
ORA-01830: date format picture ends before converting entire input string
Can u guide me how to get full date time with AM/PM?

stmtPrep.setDate(33, new java.sql.Date(dateLong));That's by design. A java.sql.Date object matches an SQL DATE column (which doesn't include a time component). If you want something which matches an SQL TIMESTAMP colum (which includes both date and time components) then you should use a java.sql.Timestamp object.

How to insert an image file as blob using JDBC Statement

Hi,
I'm new on java.
I want the code to insert an image file in Oracle database whose data type is blob.
i want to use JDBC statement not the prepared statement.
Please help me out.

user8739226 wrote:
thanks for the solution.
I want to ask one thing
let say i've created a method in a bean in which i'm passing three parameters.
One is tablename as String, Second is Name of tablefields as Object, Third is Values as Object
Like:
public synchronized int insert(String table,Object[] fields, Object[] values)Ah now we're getting somewhere. I was trying to come up with a situation where using a regular Statement over PreparedStatement would be viable and came up with practically nothing.
In the method body i'm accessing the table fields and values and combining them into the insert sql query.
how can i do this using preparedstatment.
how do i come to know here in this bean that this value is int or string or date at runtime to use setInt, setString, setdate or setBlob respectively.That's your problem. Bad design. You want to make some sort of universal insert method that can insert anything anywhere. But it doesn't really make sense, because whenever you're trying to insert something, you know exactly what you want to insert and where. You could use a PreparedStatement at that point (although encapsulate it in its own method). Now you're trying to create your own poorly designed framework over JDBC that doesn't solve problems, only increases them.
Above was the only reason i saw, i was using statement instead of preparedstatment as statement was looking easy in this situation.
please, give me the solution of above using preparedstatment.No, rather you should reconsider your design. What advantage does your insert() method give you over, let's say using a regular PreparedStatement. Granted, you can put your connection opening and other boilerplate code in the method. But if that's your only problem, then your insert method isn't gonna be much use. You could always switch to JPA for example and work with that.

How to insert autoincrement record and query it with multiple keys

Hi all,
I am not familiar with BerkeyleyDB, I am now doing a project that needs to insert records and then query it out with multiple keys at later time. Since there is no field that can be distinct primary key, I want to user DbSequence as auto increment primary key to db, and set other index keys as secondary db, then using join cursor to do query with multiple keys.
I don't know how to use DbSequence, can anyone direct me to a example of using DbSequence as auto increment primary key?
Regards
-Bruce

I figured out the method to insert record with auto increment primary key. I listed the code block below:
char m_SeqNamePositions[32] = "MyPositions";
DbSequence *m_pSeqPositions;
m_pDBPositions = new Db(NULL, 0);
          m_pDBPositions->open(NULL, pszFileName, szFileName, DB_BTREE, DB_CREATE, 0);          // 无数据文件
          m_pSeqPositions = new DbSequence(m_pDBPositions, 0);
          Dbt key((void *)m_SeqNamePositions, (u_int32_t)strlen(m_SeqNamePositions));
          m_pSeqPositions->open(NULL, &key, DB_CREATE);
db_seq_t SeqNum;
     m_pSeqPositions->get(0, 1, &SeqNum, 0);
     Dbt key((void *)&SeqNum, (u_int32_t)sizeof(SeqNum));
     Dbt data(pRecord, sizeof(*pRecord));
     return m_pDBPositions->put(NULL, &key, &data, DB_NOOVERWRITE);
m_pSeqPositions->close(0);
          m_pDBPositions->close(0);
delete m_pSeqPositions;
delete m_pDBPositions;
          m_pDBPositions = NULL;

How to insert a NULL value in SQL using JDBC Adapter

Hi All,
I have a File -> JDBC scenario.
In the File and in the SQL table I have a column called "MR_DATE" that needs to be mapped
I have to do the following:
If MR_DATE is NOT equal to "00000000"
then pass MR_DATE to SQL table
else
set the MR_DATE column in the table as NULL.
Please suggest
regards,
Piyush

Hi Piyush,
In the receiver JDBC adapter select the option Interpretation of Empty String Values as NULL.
Pass date as empty, it will be interpreted as NULL by adapter and inserted in database.

How can I get conneced to DB2 Express with JDBC?

Hi,
I have DB2 Express 8.1 installed in my computer, can I get connected to it by using JDBC step by step?
Or is there any tutorial to show how to do this?
Thank you !

There is lots of information on using DB2 UDB Express with Java, including JDBC at the IBM developerWorks site. A good first article is: www.ibm.com/developerworks/db2/zones/java/bigpicture.html
It gives a good overview of Java support for DB2. DB2 Express supports everything the rest of the DB2 product does. You build for one edition and can support on all other editions and platforms. Express is just the least expensive option in the family.
Another great resource is the DB2 Information Center. It includes all the information on DB2 including Java support and programming: publib.boulder.ibm.com/infocenter/db2help

How to determine different errors during update database with JDBC 2.0

During updating my database (MS Access 2000) using JDBC 2.0, I entered a value for the primary key field which has existed
in the database. However, when executing the method "udpateRow()" it gives me an error message "Error in row" and the
database was not updated.
When I update an Integer field with a non-integer value (e.g: Characters ), it also gives me the same error message. When I
update a Date field with a non-date value, it still displays the same error message.
How can I determine for each of the cases from the SQLException thrown that the actual error has occurred since I want to
display a different customized message indicating the different errors that occurred during updating??
Currently, part of my code is as follows:
          int currentRow = rs.getRow();
          String values[] = new String[ rsmd.getColumnCount() ];
          // Initialize values[] begins here:
          for( int count = 1; count <= rsmd.getColumnCount(); count++ ) {
               rs.updateObject( count, values[ count - 1 ] );
          try{
               rs.updateRow();
          catch( SQLException e ) {
               System.out.println( e.getMessage() );
               rs.cancelRowUpdates();
               rs.absolute( currentRow );
Can someone please help me solve this problem?? THANKS.. :)

Rather than attempting to figure out which column value causes the update to fail, I would try validating the input data before you attempt to use it in a SQL update. Of course, this would only be useful if you know what data types the inputs are supposed to be in advance of running the update.

How to set a sql query time out with jdbc:oracle:thin

should i change the JDBC driver with jdbc:oralce:XA:thin or other driver with XA?

SQL query timeout may be set with setQueryTimeout.
http://java.sun.com/j2se/1.4.2/docs/api/java/sql/Statement.html#setQueryTimeout(int)
A query timeout bug is fixed in Oracle JDBC Drivers release
10.1.0.2.0 (10g)
FIXED BUG-2249191
In the Server Internal Driver, setting the query timeout does not
+(and likely will never) work. The query execution will not be+
canceled when the timeout expires, even if the query runs forever.
Further, after the query returns, the execution of your code
may pause for the length of the timeout.

How to find the OWNER of a table with JDBC metaData?

Hi,
i write a dynamique dataBase gui for multiple dataBase (oracle, postgre..)
I want to use JDBC meta data to configure the gui
I can't find methode to optain a specifique table list for a owner...
with getTablePrivileges I see the Grantor but not the owner (the grantor isn't always the owner)
and I can't use schema because schema isn't supported by postgre
some one can help me ?
thanks a lot
Christophe

Yes of course but it is DataBase dependent...
and I want to use different DataBase...And what sort of owner would you expect in a MS Access
database?
if they are only one user we work only whith one "schema owner" the data base is structured in this way
but when multi user is possible we want to work with specifique relation beetwen different user ...
we want to use users because more dataBase suppport multiple owner than multiple schema
and generaly our information are divide in
genereral and referential information ( explain of data and list of values etc ...)
and the specifique data.
And our GUI distingue the "META DATA" and the pure "DATA" and propose specifique properties to interact with those data
i hope that my problem is better explain now .
example we use
resultSet = connection.getMetaData().getTables("","%","%",new String[]{"TABLE","VIEW"});
to optain all the table and view
resultSet = connection.getMetaData().getTablePrivileges(null,null,"tableName");
to optain privileges for a table
the trouble is that in specifique catatalog table like oracle we find a colomn whith the owner properites and when we use getTablePrivileges we can't see it idem for posgree
Each privilige description has the following columns:
TABLE_CAT String => table catalog (may be null)
TABLE_SCHEM String => table schema (may be null)
TABLE_NAME String => table name
GRANTOR => grantor of access (may be null)
GRANTEE String => grantee of access
PRIVILEGE String => name of access
IS_GRANTABLE String => "YES" if grantee is permitted to grant to others; "NO" if not; null if unknown
has you see we have GRANTOR information but not OWNER information
and the GRANTOR isn't allways the OWNER ...

Hi, Jenny,
When you said unable to insert to database, do you mean you get all ? marks in the database or garbage characters in the database?
? marks mean there are some byte chop off, and garbage characters mean the bytes are ok, just encoding problem.
