LONG Datatypes and Designer6

I have an Oracle 7.3.4.4.0 database and am using Designer 6.0.3.4.0.
I have a number of LONG fields within my database. And it appears that I'm having some troubles with the Web Modules that I'm developing. The PL/SQL code that Designer generates blows up when the text that is going into these fields is greater than 4k in size. I keep getting the "ORA-06502: PL/SQL: numeric or value error" message when the size of the text is > 4096 bytes.
Has anyone seen this or heard anything about it? Anything that I can do?

Hello I just recently successfully upgraded to leopard and everything seems like it's running fine but one thing i noticed is that it seems that leopard takes longer to startup. I also find that when I try to log out the beach ball rolls forever and the computer doesn't do anything. Has anyone else experienced this and how can I improve the performance?
Someone just pointed out that the startup problem can be related to items in your startup folder.
Under System->Accounts->Login Items see what's there. If you remove anything, remember what it was.

LONG datatype and ADO

How LONG column value could be retrieved in ADO ?
I am using OLE DB provider v. 9.2.0.2 and it returns only first 100 symbols when using Value property of Field object or GetChunk method.
Thanks

By default, ChunkSize is set to 100 bytes. You may set this property to a value between 1 and 65535 in your Connection string or registry under OLEDB subkey.
for example, ChunkSize=65535
Details as the OraOLEDB doc.

Sql syntax for converting a long datatype value in to a integer datatype value

I have to make a sql query where in i have a value of long datatype and i want to convert it into integer datatype value
null

It would have helped if you could have posted sample data.
now my requirement is to calculate the difference in hours between the start time and end time.Assuming you want the difference in time irrespective of the dates and the time is stored like HH24:MI:SS format, you could try something like:
SQL> WITH test_tab AS
2       (SELECT '09:12:33' start_time, '12:30:33' end_time
3          FROM DUAL
4        UNION ALL
5        SELECT '09:12:33' start_time, '14:12:33' end_time
6          FROM DUAL)
7        -- end of test data
8 SELECT end_time, start_time,
9         TRUNC ( ( TO_DATE (end_time, 'HH24:MI:SS')
10                   - TO_DATE (start_time, 'HH24:MI:SS')
11                  )
12                * 24
13               ) diff_in_hours
14    FROM test_tab
15 /
END_TIME START_TI DIFF_IN_HOURS
12:30:33 09:12:33             3
14:12:33 09:12:33             5
2 rows selected.Hope this helps,

HS generic and long datatypes in Oracle 8i

I have a problem importing LONG datatype columns
from Hyperion Pillar to Oracle (version 8.1.6.0.0) using
the (Hyperion supplied) ODBC driver and generic HS.
The error message I get is
ORA-03001: unimplemented feature
ORA-02063: preceding line from PILLAR.WORLD
From the message it seems clear that Oracle cannot
deal with longs using generic connectivity (at least
in v. 8.1.6).
My questions:
1) Is there a workaround ?
2) Does this work in 9i ?
Notes:
1) The problem is not with the ODBC driver, as I
can see the long datatype columns using another
tool which connects to Pillar via ODBC.
2) HS has been set up correctly because all datatypes
other than long can be viewed in Oracle without any
problems.
3) Operating System: Windows NT 4.00.1381
Any help would be much appreciated!
Kailash.

Thanks for the reply.
Pillar LONGS (or MEMO, as they are referred to in Pillar)
map to ODBC SQL_LONGVARCHAR. So it appears that the
mapping is OK, and that SELECTing from these columns
should be possible via generic connectivity.
Any other ideas on what may be wrong? Any help is
much appreciated.
Thanks,
Kailash.

JDBC Thin Client and Oracle Long Datatype

I am using Wepshere 4.0.2 , JDBC 2.0 (thin driver) and oracle 9i.
I have a procedure which takes Oracle Long Datatype as its parameter.
I use following code to execute procedure.
String dataforsql="AAA000000003 123123 07/01/200301/01/2003";
byte[] bytes = dataforsql.getBytes();
InputStream is = new ByteArrayInputStream(bytes);
cstmt=conn.prepareCall("call nscw.CPPF_SAVEPDCRAWTABLE2(?,?,?)");
cstmt.setAsciiStream (1, is,bytes.length);
The above code works perfectly for data upto 4000 bytes. Once the data crosses the 4000 mark.
i get a procedure error
ORA-01460: unimplemented or unreasonable conversion requested

cstmt.setAsciiStream (1, is,bytes.length);Oracle's support for CLOB (and BLOB) columns using set{Ascii,Binary}Stream() generally s*cks. You'll have to read Oracle's own JDBC manual (you can read it online at http://technet.oracle.com) for whatever sequence they recommend.
E.g. for insertion and updation of CLOBS, you're supposed to use an oracle-specific function (EMPTY_CLOB()) as the value in the INSERT/UPDATE statement, and then do a SELECT, getClob(), and use Clob APIs to update the actual column value. At least officially. Or you have to use some Oracle-specific APIs in oracle.sql.Connection and oracle.sql.CLOB.

Exporting a table with Long datatype col. name

Hello,
I need help exporting a table, One of the column is long datatype.
How can I do this without using Export Util?
Is it possible.
(If someone has a solution then PLEASE Email
me)
URGENT.
Thanks.
Pankaj Patel.

Just wanted to find out, if you already solved this problem. I have a similar issue with long column. I am trying to sql dump a table with long column that will be imported into another database(probably using sql*load), but the spooled file puts the data from the long column in separate lines 80 char long and not on a single line. I have set the long to 64000 and linesize to 32000. Wrap is on too.

Long Datatypes in Reports

I have a field of long datatype in a table. I need to display the first 200 characters of this field in a report.
How can I do this. If it is thru Placeholder columns can you explkain in detail how I should go about this.
null

It was in the 8i migration guide (http://download-uk.oracle.com/docs/cd/A87860_01/doc/server.817/a86632/migaftrm.htm#6573), but we decided to get to 10g first and then take care of it (since we did a 7 to 10 upgrade in two steps, 7->8 and 8->10).
So basically I should just leave the SYSTEM tablespace objects alone then? I only tried the system objects conversion on a test database, and since the non-system objects were fine, we converted them on production but left the system ones alone.

Extracting clob/blob/long datatypes in delimited file

I have a few tables in database that have clob/blob/long datatypes. I need to unload this data into delimited file and reload the data into another database. I don't want to use export/import.
Currently the code that i have can handle varchar2, number, date datatypes quite easily using sqlloader.
The tables are not too big (hundred to 10k rows approximately) and performance is important but not crucial. The script can run for a few minutes unloading data, that is fine. Code maintenance is of higher priority with pl/sql being the preferred scripting language.
From the sqlloader manual, i glean that use of special delimiter is important, something like <startlob> and <endlob> .
I need ideas on how to do this.

Hi Buddy.

VERY URGENT: problem in sql query with long datatype in weblogic

I have a problem while tryind to retrieve a column value with a long datatype using servlet and oci driver and the server is weblogic5.1 .I have used prepared statement the problem comes in the
preparedStatement.executeQuery().
The sql Query is simple query and runs well in all cases and fails only when the long datatype column is included in the query.
The exception that comes on the weblogic server is that :
AN UNEXPECTED EXCEPTION DETECTED IN THE NATIVE CODE OUTSIDE THE VM.

Did you try changing the driver then?
Please use Oracle's thin driver instead of the oci driver.
There are many advantages of using the type 4 driver. the first and foremost being that it does not require oracle client side software on your machine. Therefore no enteries to be made in tnsnames.ora
The thin driver is available in a jar called classes112.zip the class which implements the thin driver is oracle.jdbc.driver.OracleDriver
the connection string is
jdbc:oracle:thin:@<machine name>:1521:<sid>
please try out with the thin driver and let me know.
regards,
Abhishek.

Illegal use of LONG datatype error message when i create materialized view

Hello to all
I want create read only materialized view replication environment two of our tables have LONG datatype when i create materialized view against on them
I recieve this error message
CREATE MATERIALIZED VIEW MDB.TOAD_PLAN_TABLE TABLESPACE aramis REFRESH FORCE WITH ROWID AS SELECT * FROM MDB.TOAD_PLAN_TABLE@arahisto
Error report:
SQL Error: ORA-00997: illegal use of LONG datatype
00997. 00000 - "illegal use of LONG datatype"
Do you know any resort solution for it?
thanks

You can not use longs in materialized views over a database link, you can however take a part of a long over to a materialized view.
I have gotten this to work in the past l had to create a PL/SQL function that you can use to extract the character data from the long column and use that to
as part of the function you will need to pass in the columns of the table that will identify the unique records so you can pick out the long column
example function
-- you will need to make sure this funtion is in the remote location as you can not select longs accross a DB LINK.
CREATE OR REPLACE FUNCTION MDB.TOAD_PLAN_LONG_CONV
(pass in the primary key columns for the table)
RETURN VARCHAR2
IS
v_long VARCHAR2(32767) ;
BEGIN
BEGIN
-- need to select the long column into the PL/SQL variable
SELECT long_column
INTO v_long
FROM MDB.TOAD_PLAN_TABLE
WHERE key_columns = passed columns ;
EXCEPTION
WHEN OTHERS THEN
IF SQLCODE = '-01406' THEN
NULL ;
ELSE
RAISE ;
END IF ;
END ;
RETURN SUBSTR(v_long,1,4000) ;
END ;
Then when you create the materialized view utilize that function on the long column.
create or replace materialized view MDB.TOAD_PLAN_TABLE TABLESPACE aramis REFRESH FORCE WITH ROWID
AS
SELECT column1, .... columnx,
MDB.TOAD_PLAN_LONG_CONV@arahisto (primary key column list) as long_column_name
FROM MDB.TOAD_PLAN_TABLE@arahisto ;
See if this will work for you? Keep in mind however this solution will not get the entire long column only as much as a PL/SQL variable will hold of it.

Using Decode with "Long" datatypes

Hi,
I want to use a select statement in a view which uses a decode function involving a "long" datatype. But doing some raises an error "Invalid datatypes". Is there a way around?
Anupam.

I'm a bit puzzled as to what it is you are trying to achieve (it has been an afternoon for vague requirements). Normally the sort of data that we would want to store in a LONG is ,er, long and therefore not susceptible to use in a DECODE. But it does not matter, because we can only manipulate LONGs in PL/SQL and that does not parse DECODE statements. We will have to use IF...ELSE constructs instead.
CREATE OR REPLACE FUNCTION l2v (pl in rowid) RETURN VARCHAR2
AS
    ll LONG;
    rv VARCHAR2(20);
BEGIN
   SELECT col1
   INTO ll
   FROM   T_LONG
   WHERE rowid = pl;
   IF ll LIKE '%text%'
   THEN
      rv := 'yes!';
   ELSE
      rv := 'noooo';
   END IF;
   RETURN rv;
END;
SQL> select l2v(rowid) from t_long;
L2V(ROWID)
yes!
yes!
SQL> You can use this function in a query. Note that it is doing a SELECT in its own right so this will not be a very performant solution if you build the view on a big table.
Cheers, APC

Copying data contianing long datatype from one schema to another

I'm using Oracle 8.1.7 and trying to move copy data from one schema to another.
Usually an easy task. This time the data contains longs so I can't use standard SQL. The data in the long is too long for a PL/SQL long datatype so that's not worked.
I've tried the COPY FROM command but get the invalid sql command error.
Can anyone save my hair?

The COPY command doesn't have to be all on one line. The continuation character for SQL*Plus commands is a hyphen.

Selecting a Long datatype

I have created a select statement and saved it to the variable sql_str. I then Open the cursor "OPEN v_cursor FOR sql_str;".
One of the columns in the select statement has a datatype of LONG. I fetch the column into a variable that I have declared as Long. I get the following error: ORA-00997: illegal use of LONG datatype.
What am I doing wrong?

Need a Help building Longer datatypes

Hi Friends,
I have a Complex problem right now.
I am trying to build a longer datatypes of an unsinged interger where in we can specify the length of it where in we can specify number of bits required to store the data and is this is exceeding the long int data type of c++.
I tried to build this by using the concepts of unsigned integer algorithm.
I would really appericiate if some one can help me in converting it too java.
One of the main difficulties i am facing right now is i do not have any idea about how to overload Arithmatic operators like (+,-,*,/ ,% ....) in java.
I would really grateful if somebody can help me in this regards....
Thanks in adavance!!!
