I would like to know if there is possible to transform a CLOB type variable intro a long type variable. I know, that LONG is obsolete in Oracle, but I need it, because in a PL/SQL 'execute immediate' sentence a CLOB is not allowed.
I have a task to update one of the rows in a table (having only 2 columns, number and long) which is long data type. We are on Oracle 10g. Not sure how to use update for a long data type column.
I have tried using dbms_metadata_util.long2varchar, but still not getting what I want.
I have a form with an item with "datatype=long". when I am typing in "Arabic" or "Persian" it break the text before line ends.but when I type in English "text" go to end line(in other words line fills to the end) and then breake to next line.It show that the problem is LANGUAGE.
nls_lang=AMERICAN_AMERICA.ar8mswin1256 Regional and language/regional option=Arabic(U.A.E) in the block/item property : wrap_style= word ----multi_line=yes
I have a long datatype field in which text of length more than 4000 is stored. I want to use editor for entering and displaying the data, but it shows the error:-
case 1: when editor is invoked directly- FRM-40735: WHEN-BUTTON-PRESSED trigger raised unhandled exception ORA-06502 case 2: when I write something in the field- FRM-40209: Field must be of form.
We are working on a performance tuning aspect, where in a table has a LONG datatype and number of round trips are increasing based on the number of rows fetched.i.e one round trip for every row.
Background.
1. created a table with LONG data type. 2. inserted bulk load of data. 3. set auto trace on and executed below tests..
SQL> select count(*) from test_long;
COUNT(*) ---------- 6110
SQL> desc test_long Name Null? Type ----------------------------------------------------------------------------------------------------- -------- ---------------------------------------------------------------------------- ID NUMBER TESTLONG LONG [code].....
but on LONG column, irrespective of the array size the round trips does not reduce.
Some materialized views get status broken on refreshment, but only sometime. When I try to refresh them manually I get following message:
"ORA-01400: cannot insert NULL into...".
But I know for sure that there are no NULL values in the master table, MV and master tables are declared in the same way and all columns in master tables are NOT NULL columns. Another ting is that this error I get only on columns with data type CLOB.
I have a data synch procedure where I am extracting data from an Oracle table and inserting it into a SQL Server table. The Oracle column is VARCHAR2 and the receiving SQL Server column is Binary. I am receiving a conversion error. I have tried HEXTORAW in the Oracle procedure but it does not work. What data type can I use.
I am more of a C/C++ guy and relatively amateur in oracle. I have to update a table field from "Long" to "CLOB". I have planned to do a simple alter table, and as far as I know there won't be any issues.
Queries: 1. Although I have triple checked, is there any scenario under which there can be any data loss during the data type change? The data is very critical and no data loss can be entertained. 2. Is there any easy way to update all the related views without having to do so manually? 3. Any particular precautions I should take before introducing the change?
We have a huge table in production, with LONG column. We are trying to change its datatype to CLOB. The table has 120 Million records and is of 270 GB in size.
We tried using the oracle expdp/impdp option to try the conversion in our perf environment. With 32 parallels, the export completed in 1.5 hrs. However, the import took 13 hrs.
I also tried the to_lob option using inserts, it went on for 20 hrs and I killed the process. Are there any ways to improve the performance of LONG to CLOB conversion on huge tables?
display or get values stored in a long column.i tried the below code, but myvar is shown as null. am i missing something here or is there a better apporoach than this ?. There are actually 16 rows returned for this query but with empty values for 'high_value' column which is critical for me. How can i do this long to varchar convertion ?
SET SERVEROUTPUT ON DECLARE my_var long; BEGIN for x in ( SELECT high_value FROM all_tab_partitions WHERE table_name = 'SALES_DISCOUNT' AND table_owner = 'CED12' ORDER BY partition_position DESC ) [code]....
Im having mail content column of type long Raw in a table.i just want concat or append a value in that column when i tried it shows error "illegal use of long type".how to append value to it. value will be string type
I created a custom type what it has a clob member variable:
CREATE TYPE custom_type AS OBJECT( c_type INTEGER, c_number NUMBER(38, 8), c_varchar2 VARCHAR2(4000 CHAR), c_clob CLOB, [code]........
The inserting and updating works with constructor: ... custom_type (to_clob('foo')) . But if the data is longest than 4000 characters then the PHP isn't access to it.
So: The normal case: $sql = ("INSERT INTO table ( clob_field ) VALUES ( EMPTY_CLOB() ) RETURNING clob_field INTO :clob"); $stid = oci_parse($conn, $sql); $clobdescr = oci_new_descriptor($conn, OCI_DTYPE_LOB); oci_bind_by_name($stid, ':clob', $clobdescr, -1, OCI_B_CLOB); oci_execute($stid); $clobdescr->save('more than 4000 chars'); ...
This case: I tried: $sql = ("INSERT INTO table ( ctype ) VALUES ( custom_type(EMPTY_CLOB()) ) RETURNING ctype.c_clob INTO :clob"); $stid = oci_parse($conn, $sql); $clobdescr = oci_new_descriptor($conn, OCI_DTYPE_LOB); oci_bind_by_name($stid, ':clob', $clobdescr, -1, OCI_B_CLOB); oci_execute($stid); $clobdescr->save('more than 4000 chars');
ORA says: "ORA-00904: CTYPE.C_CLOB: invalid identifier";
create type emp_obj_dtl as OBJECT (ename varchar2(50),mgr NUMBER) create type emp_dtl_obj_typ as TABLE of emp_obj_dtl
Using the these object i have created on function as
CREATE OR REPLACE FUNCTION emp_test_func (peno NUMBER) RETURN emp_dtl_obj_typ AS lv_emp_dtl emp_dtl_obj_typ := emp_dtl_obj_typ (); BEGIN SELECT emp_dtl_obj_typ(emp_obj_dtl (ename, mgr)) INTO lv_emp_dtl FROM emp WHERE empno = peno;
RETURN lv_emp_dtl; END;
Now if i am executing query as
SELECT empno, emp_test_func (empno) emp_dtls FROM emp
But now I need to convert all my CLOB data into UTF-8 charset for external requirements and stored this new CLOB in a table column.
I can't change the charset of the session. I've tried to use a function
{code} FUNCTION convert_xml (pcl_xml IN CLOB) RETURN CLOB
[Code]....
This function apparently works, but when I try to validate the XML content (after I replace the encoding="ISO-8859-1" to encoding="UTF-8") the validation software tells me that I have some characters that should not be present in a file using UTF-8 encoding.
I got an exception when I was using sesame adapter to dump a turtle file which contains long texts as objects into oracle semantic database. The exception information is:
