SQL & PL/SQL :: Update Clob Column Using Execute Immediate?
Aug 30, 2010
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.

I need to update the record(id = 100) by replacing the url "http:/localhost/icons/sandiego.png" with "http:/localhost/icons/okinawa.png".
I need a procedure where I will pass the ID value, replace string(i.e http:/localhost/icons/sandiego.png) and replace with string (ie. http:/localhost/icons/okinawa.png).

I am trying to execute an UPDATE from a field that may have more than row. I get ORA-01427: single-row subquery returns more than one row.
I need to set the careof column in owner table to hold the name (NAM) from the alt table if the alttype from alt is ATT. We could have more than one id and the careof names can be different.
This is my query:
UPDATE owner s
SET s.careof = (SELECT a.NAM
FROM alt a
WHERE a.taxyr = '2011'
AND a.alttype = 'ATT'
AND a.card in ('0')

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'm editing, say, list of my employees in a tabular form opened in Skillbuilders Modal Page. I have to execute same javascript code after the changes in the tabular form have been submitted.
I've tried using a Dynamic Action fired on Page Load, but that gets executed before the update is completed.

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.

I am doing a simple test and need to populate a small table with some data.
My table looks like this:
SQL> desc clob_test
Name Null? Type
----------------------------------------- -------- ----------------------------
ID NUMBER(20)
C1 CLOB
I have a pipe delimited data file ID range 1-50000 and random characters with a length of 100-4000 bytes for the clob field.
My control file looks like this but I am guessing it is wrong:
LOAD DATA
INFILE 'clob_test.dat'
INTO TABLE CLOB_TEST
FIELDS TERMINATED BY '|'
TRAILING NULLCOLS
(
ID INTEGER EXTERNAL NULLIF (ID=BLANKS)
, C1
)
Let me know what I need to do to my .ctl file in order to load this data?

Links from where I can get related info. Also I would like to know the impact of such index on performance. I have to store and process around 50 million records in such a way, will it be beneficial to use this index?

I have a table with two clob columns and need to manually allocate space to the table and to its lob segment. Is the following command correct?
--to allocate extent to the table
alter table emp allocate extent;
--the table has columns named col1 and col2 which are clob
--to allocate extents to the columns
alter table emp modify lob (col1) (allocate extent (size 10m))
/
alter table emp modify lob (col2) (allocate extent (size 10m))

I have extracted data from table and write into one text via sqlplus utility in shell scripts. i got correct output. i am having two issues on the output file
1) Outfile file size is huge high compare then table segment data.
2) last column having extra space.
The output column is clob datatype. so i have added set long 50000 and set longchunksize 50000 parameter. after adding these only i got above issues. without two options, i am not getting this isssue but lines are wrapped.
