I have a CLOB column in one of my tables (Table1), which stores very large (150MB+) XML files. I have new/another table (Table2) in the DB where I have an XMLType column. I want to take the CLOB data (xml) from table1 and remove some part of that and store the rest into to the XMLType column of Table2.
I want to remove the data inside the XML tags
<Attachments>
very long data goes here... which I don't need, which should be replaced with a single word

store the CLOB to XMLType column after removing the unwanted data.
Replacing a new line character in clob column i Oracle 10g.I have tried replacing the new line using regexp_replace,replace and translate. I have also tried using lob_relace procedures.
I have few tables in Oracle 9i/10g , and they already have data in them. I am trying to migrate the data coming from various source systems into these Oracle tables. There is a chance that after loading I might get some unwanted data into these tables.
How do I remove just that data which I have loaded recently, and do not disturb the original data it already has.
Need to backup those tables and reload the data back if there is any problem, but I am looking at a different approach. I just don't want to change the existing system, as lot of users use the system.
I have a column named account_detail of data type Varchar2(70). I want to enforce a law such that all data being entered in this column is entered as
22 22 22 22
which means there is a space after every two digits. How do I achieve this through oracle forms, is there a way in the property pallette through which I can set it's property to reflect this change or should I do this with key-next-item.
As you can see, I removed the first four columns because the eventkey is the same. In this case, there is only the applicant which is different.So the rest should be blank.
i have a table that contains employee id, employee name , so if i gave the correct employee id in where clause of select statement it will show employee name, in case if i give the employee id that does not exist in the table it will show 'Employee name is not found'..
We would like to remove the partitions from a particular table. The table in question has 12 partitions. Based on some initial investigation, I've come up with the following options. because the table we going to remove partition will have millions of records so on considering the db downtime we are looking for a alternative way. Is there a better way?
Copy data into another table, drop all partitions, then copy the data back into the original table Copy data into another table, drop the original table, then rename the new table and rebuild the indexes.
Our application has been installed at customers in North America, Europe and South America for several years, in some cases, over 10 years. At least one of our customers has hundreds of gigabytes of data. We are considering options for cleaning out the old data.
The database runs on a variety of systems (Linux, Windows, Unix) and in several version (Oracle 9, 10, and 11). We need a solution that works in all environments.
Two of our main criteria for a successful solution are that: -It maintains application data referential integrity. Our application makes little use of foreign key constraints, so the cleanup process will apply critical business rules to candidate data to determine if it can be deleted or not. -The operation of the cleanup program does not impact use of the system in production.
For various reasons (license cost, installation issues) the partitioning option is not available to us.
Alternative 1: Flag records for cleanup
This requires adding a 1-character column to each table. That is a one-time operation done during implementation. The procedure applies the business rules and sets the flag according to whether a row is to be deleted or not. Rows marked for deletion can be checked, reset, exported, etc. Finally, a separate process deletes all marked rows.
Advantage of this is that the deletion process will use a full table scan to find the marked records. There is no index navigation, so hopefully less overhead. Disadvantage is that its updating application data which might affect user's perceived system response. There is some undefined concern that locking or other table activity involved with updating the flags could impact users.
Alternative 2: Build a list of keys for data to be deleted
We will build a list table during implementation. The first process examines the application data, applies the deletion rules and writes key information to the list for data that can be deleted. The list can be checked, reset, rebuilt and listed rows can be exported as required. Finally, the cleanup process uses the list to find and delete the data.
Advantage is that it doesn't update the application data as its building the list. Disadvantages are that it that there is some overhead in building and checking the list. The list requires more space than the flags in alternative 1 but we can handle that in various ways. The procedure needs to navigate key structures during the delete step as well as in the list-building phase.
I'm writing a PHP page to display some data from an Oracle database. Unfortunately, I can't copy the code because it's proprietary. One of the columns in the db is of type CLOB. I'm having trouble getting the data from the CLOB column.
The way the code is now, is there is a query string read into a variable, and the query string variable is read into a function that then retrieves the data from the db. Once the result set is returned, it is parsed to get data from all of the columns. The issue is that I've never worked with CLOB data before, so I'm having some difficulty extracting the data for that column. I know I can use the DBMS_LOB.READ function, but I'm not sure how to apply it in this case. The following is a generic form of the query string I'm using with b.clob_col being the column I'm having issues with.
$queryString = <<<EOD SELECT a.col1, a.col2, a.col3, b.col4, b.col5, b.clob_col, from table1 b inner join b.col4 on blah1 inner join a.col2 on blah2 where blah and blah EOD;
I'm trying to write a package which will allow my users to send emails, based on templates, from our system. The email body templates are stored as text in a CLOB column in a EMAIL_TEMPLATES table, along with an email_id. Here's an example:
Quote:Dear [dearname],
I write with regard to your child, [childname] who is attending [schoolname].
Now, I'm trying to write a procedure that will take an email_id and the fields such as dearname, childname, etc., merge the data into the template and return the final body of the email.
The email body will then finally be inserted into a standard HTML email template and be sent using UTL_MAIL.
I was planning on using a series of nested REPLACE functions but I'm sure there must be a tidier way than that. Particularly as I would like the procedure to be as flexible as possible to allow me to easy adapt it to receive additional fields for different email templates in future.
I am trying to extract XML data stored in a CLOB and produce a flat file for the user's consumption. They have sent me what they think is the XSD for the XML data but when I look at the data in the CLOB I don't see the tags documented in the XSD. I'd like to produce an XSD based on the actual data to compare with what they've sent. Is this possible? I am able to query the XML data using the tags I see in the data using XML Table and it's working fine.
I want to know whether is it possible to send CLOB data automatically using CDC...i usually have to run a procedure manually to send such data to remote locations.
I need to pass a large data into one of the tables where the column is declared as CLOB before which I was checking with the sample code as below which is throwing an error.
I was trying to insert the CLOB data into the table as below.
create table t1 ( x number, y clob ); insert into t1(x) values (2) declare l_clob t1.y%type;
[code].....
The error I am getting is:
ORA-06502: PL/SQL: numeric or value error: invalid LOB locator specified: ORA-22275 ORA-06512: at "SYS.DBMS_LOB", line 833 ORA-06512: at line 161
I have one table with clob field. The data in this field will contain string having transaction record data. Now I want to read data from this clob filed and insert different record in other oracle table.
example -> Data in clob field will be-> H|12|1233|fff|sss L|1234|gggg|tttt|yyyyyy|rrrrr L|1094|gggg|tttt|yyyyyy|rrrrr L|1344|gggg|tttt|yyyyyy|rrrrr L|1666|gggg|tttt|yyyyyy|rrrrr L|188|gggg|tttt|yyyyyy|rrrrr
I have one master table and one detail table. I want to insert record -> H|12|1233|fff|sss in master table and records-> L|1234|gggg|tttt|yyyyyy|rrrrr L|1094|gggg|tttt|yyyyyy|rrrrr L|1344|gggg|tttt|yyyyyy|rrrrr L|1666|gggg|tttt|yyyyyy|rrrrr L|188|gggg|tttt|yyyyyy|rrrrr in detail table.
End of excercise will redult-> 1 record in header and 5 records in detail table.
I want to print data from a clob in XML format and use the following
PROCEDURE printClobOut(result IN OUT NOCOPY CLOB) is xmlstr varchar2(32767); line varchar2(32767); cnt NUMBER;
[Code]...
However the length of the clob is 13832630 which is too large for a VARCHAR2. Thus my output of line is cut off at 4000 characters. How can i increase this... Do i overlook something here in my code?
i have a problem when i try to insert a large character string of nearly 1 lac characters (code of html) in a clob column of my test table, then i get an error "ORA-01704: string literal too long" , i didnot understand that why clob column is not storing this data.
I have a requirement where in I have to store large data in one of the database columns using stored procedure.
I have declared the column as CLOB as it can store upto 4GB and also the input parameter for the procedure as CLOB. But when I am trying to pass large data it is not allowing to store as it is throwing literal string too large error.
Is there any restriction in the data size to be passed to the stored procedure?
I am migrating data from DB2 to Oracle. I used DB2 export to extract the data specifying lobsinfile clause. This created all the CLOB data in one file. So a typical record has a column with a reference to the CLOB data. "OUTFILE.001.lob.0.2880/". where OUTFILE.001.lob is the name specified in the export command and 0 is the starting position in the file and 2880 is the length of the first CLOB.
When I try to load this data using sqlldr I'm getting a file not found.Attached is a copy of the control file and output from testing
PS. I cant use the DB2 option LOBSINSEPFILES which creates a separate file for each CLOB column because the table has over 14 million rows....and creating 14 mil files causes OS inode problems...
