Jun 30, 2010
I have oracle table with a column of datatype CLOB. In the clob column having the manipulation statements (update, insert) as records.
How to execute the statements exists in a clob column as records?
my table structure and one record is
CREATE TABLE ACTN_CFG_T
(
OBJ_ID NUMBER(32) NOT NULL,
ACTN_ID NUMBER(38) NOT NULL,
ACTN_SEQ NUMBER(2) NOT NULL,
RU_DEF CLOB NOT NULL
[code]....
I want to execute the update statement when i call the obj_id. I used the follwing procedure but error.
1 DECLARE
2 V_ABC CLOB;
3 BEGIN
4 SELECT RU_DEF INTO V_ABC FROM ACTN_CFG_T WHERE OBJ_ID = 1625;
5 EXECUTE IMMEDIATE V_ABC;
6 END;
error is...
ORA-06550: line 5, column 20:

I am encountering an error message while updating a xmltype column using dynamic sql statement. I am using dynamic sql here as the table is not placed in the same schema from where the plsql procedure is invoked. The schema name is passed to the procedure as an argument. I am using below pseudo code for this purpose.
Create procedure myproc(p_schemaname varchar2, p_id number)
is
p_clob clob;
p_str varchar2(2000);
begin
[code]...
This is throwing an error 'missing expression' at the line of 'exeute immediate'.
But it works if I run a static sql update by hard coding the schema name in the statement.

reconciliation logic using Oracle
Version
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
PL/SQL Release 10.2.0.4.0 - Production
CORE 10.2.0.4.0 Production
TNS for Solaris: Version 10.2.0.4.0 - Production
NLSRTL Version 10.2.0.4.0 - Production
Current written logic for reconciliation:
1. Load data from source_a in a staging table using date filter
2. Load data from a file (Source_B) in temp table
3. Algo for reconciliation:
fetch value from source_B and if an entry exists in source_a then match say 10 columns if they match update reconciliation_oke = TRUE
there is an and written for testing all the 10 columns There is report generated out this which shows non matched columns and the entries which are missing....Now the requirement is to modify the logic in a way which shows which all columns are mismatched on the report in case present.
Since there are around 10 thousand records which would be reconciled on a daily basis, performance also needs to be taken care of...I guess i would be required to use PL/SQl tables...

Is it possible to create sequence using EXECUTE IMMEDIATE statement. The sequence name will be the bind variable.
DECLARE
TEMP VARCHAR2(20);
BEGIN
TEMP := :P2_INFO;
EXECUTE IMMEDIATE 'CREATE SEQUENCE' TEMP;
END;
This creates a sequence named TEMP, but i want the name :P2_INFO entered by user.

I have a procedure as below. To sum up the procedure in one line it dynamically forms a string to get the values of the type which is passed as an input to the procedure.
I call the procedure as
exec exec_imm( exec_imm_t(1,'asd','1/2-34'));
ERROR:
Error starting at line 9 in command:
exec exec_imm( exec_imm_t(1,'asd','1/2-34'))
Error report:
ORA-00904: "P_TYPE_DATA"."ADDRESS": invalid identifier
ORA-06512: at "PTK_ADM.EXEC_IMM", line 26
ORA-06512: at line 1
00904. 00000 - "%s: invalid identifier"
NOTE:
When I try to execute the procedure with the execute immediate statement I get the above error. But when I execute the select statement which is nothing but the value in v_type_data directly (as seen in the comments in the code below) there is no error. But when the same v_type_data is used in execute immediate, I get an error.
CREATE OR REPLACE procedure exec_imm(p_type_data exec_imm_t)
AS
v_type_str CLOB := NULL;
v_type_data CLOB := NULL;
v_type_name VARCHAR2(25) := NULL;
BEGIN

I've been trying to write some code to add a column if it does not exist as the code will be run numerous times and will be parameterized in other software to run across multiple tables.
Here is what I have made so far:
DECLARE
COLEXISTS integer;
vCmdStr varchar2(4000);
[Code]....
I can't figure out where the invalid character is.

1 A
2 B
3 C
SUBJECT

SUBCODE SUBNAME LECTURER
======= ======= ========
A1 ABC 1
A2 EFG 2
A3 HIJ 1
I did the following query
SELECT STAFF.STAFFNUM, STAFF.NAME, SUBJECT.LECTURER
FROM STAFF,SUBJECT
WHERE STAFF.STAFFNUM NOT IN SUBJECT.LECTURER
It will show me..
B and C is not teaching A1.
A and C is not Teaching A2.
B and C is not teaching A3.
This is not what I want.
What I want is to show who is not teaching any subjects.So the expected result is only C coming out.

I am creating an index in program and then drop the index at the end of the program. Some times due to some problem if the index could not be dropped and the user again runs the program then we get the error
ORA-01408 Index already exist on the column.
how I can get away with this error or how I can check whether the index with the same columns exits prior to creating an index.
Is there any command like
Create or replace index.....

I have two tables File_Master and File_Detail
File_Master Primary key FILE_ID
File_Detail Primary key FILE_ID,LINE_ID
I have a CLOB column FILE_CONTENT in table File_Master. For every FILE_ID record in File_Master, several hundreds of lines are stored in the CLOB column.
I want to read this CLOB column 'File_Content' and and break every line (1000 Characters)
piecewise to populate columns of File_Detail.
Since there will be thousands of lines to process, what would be the best approach in writing PL/SQL code for better performance?

I have a requirement when I need to append and show the contents of a CLOB (rich text) column into the Open office report.
The use case is as below.
User(s) can enter the details into a CLOB column.
This data entered by each user need to be concatenated onto another CLOB column which will hold all the history of changes. Mainly i wanted to perform a concatenation of these two columns.
|
| User Entered | Stored |
| Data Stored in Clob Column 1| Data Stored in Clob Column 2 |
| v_clob_1 | v_clob_target |
-------------------------------------------------------------------------------
|"Text 1" and a image |"Text 1" and a image |
-------------------------------------------------------------------------------
Any method to achieve this case. I had tried the following method to achieve this. But no success.
v_merge clob;
v_clob_target clob;
v_clob_1 clob;
1)
DBMS_LOB.APPEND(v_merge, v_clob_target);
DBMS_LOB.APPEND(v_merge, v_clob_1);
2)
DBMS_LOB.APPEND(v_clob_target, v_clob_1);
3)
v_merge:= v_clob_target || ''|| v_clob_1;
v_clob_target := v_merge;

I had a varchar2 variable which was storing some data and I could use the LENGTH function to get the length of the data. However, If I change it to CLOB. What is the best way to get the length?
v_clob_size:= (DBMS_LOB.getlength(v_clob)) / 1024 / 1024;
DBMS_OUTPUT.put_line('CLOB Size ' || v_clob_size);
another one is
LENGTHB(TO_CHAR(SUBSTR(<clob-column>,1,4000))) But this seems restricted to first 4000 characters only.

I have a CLOB column called XML_DATA that has (not-surprisingly) xml data in it that's housed inside a table called HMS_XML_TRANSFER. It has been giving me a headache because I'm unable at this point to use the xml field as a condition to get its TRANS_SEQUENCE number. The where clause doesn't work.
SELECT TRANS_SEQUENCE, XML_DATA
FROM HMS_XML_TRANSFER
WHERE EXTRACTVALUE(XMLTYPE (XML_DATA), '/INTERFACES/INTERFACE/BODY/IFI0057[ACTIVITY_CODE = "2201-020742"]');
The only test that I have been able to get working is the one below.
SELECT TRANS_SEQUENCE, EXTRACTVALUE(XMLTYPE (XML_DATA), '/INTERFACES/INTERFACE/BODY/IFI0057/ACTIVITY_CODE')
FROM HMS_XML_TRANSFER
WHERE TRANS_SEQUENCE = '8191602';
It will give me the ACTIVITY_CODE element so I know I can pull data from the XML but I can't do the reverse in the first example which is what I need because I don't know the TRANS_SEQUENCE number, I just know the ACTIVITY_CODE.
I have over 202 error messages logged in Teradata SQL from my many and varied attempts to get this to work using every example I could find online.
As an example this has not worked either...
WHERE EXISTNODE(XML_DATA, '/INTERFACES/INTERFACE/BODY/IFI0057[ACTIVITY_CODE = "2201-020742"]') = 1;
So the question... How do I properly form my SQL statement so I can use the XML column's ACTIVITY_CODE element to get the TRANS_SEQUENCE column field? Oh and I'd like to see both columns in the result.
Below is the version of Oracle I'm using, the description of the Table HMS_XML_TRANSFER, and a sample of the XML that comes from XML_DATA. I can't seems to get tabs working.

I have to change the datatype of a column from CLOB to varchar2, without changing the order of the columns. The table has no data.
I could find any other way other than dropping the CLOB columns and then adding new columns with varchar2 datatype. But this changes the order of the columns in the table.
