clob

I recently upgraded an application to run using JAVA 7 and JBoss 7.1.1 This application was originally developed on JAVA 5 and Jboss 4.2.2. This application uses hibernate 3 for persistence. On the new platform, the application is failing when there is an attempt to INSERT into a table with CLOB fields with the above error. I am using ojdbc14.jar (backend database Oracle 10.2.0.3) These are things that I have verified in jboss 7.1.1 configuration: Creation of the correct module for Oracle. Ensured that ojdbc14.jar exists in the correct modules directory Ensured that there are no other

There's a lot one can find about this googling a bit but I haven't quite found a workable solution to this problem. Basically what I have is a big CLOB on a particular class that I want to have loaded on demand. The naive way to do this would be: class MyType { // ... @Basic(fetch=FetchType.LAZY) @Lob public String getBlob() { return blob; } } That doesn't work though, apparently due to the fact I'm using oracle drivers, i.e. Lob objects aren't treated as simple handles but are always loaded. Or so I've been led to believe from my forays. There is one solution that uses special instrumentation

Say you have the table: Column_name | data_type Title | Varchar2 Text | CLOB with some rows: SomeUnkownMovie | A long time ago in a galaxy far, far away....(long text ahead) FredMercuryBio | Awesomeness and stuff....(more long text) Is there a way I could query that so it outputs files like SomeUnkownMovie.txt FredMercuryBio.txt (and ofc, with their respective texts inside) I reckon this should be a easy enough sqlplus script.. though I'm just not the one :( thanks! LukStorms This pl/sql code should work in oracle 11g. It dumps the text of the clobs into a directory with the title as filename.

I have this CLOB column and I need to display it using a select statement. I used DBMS_LOB.SUBSTR to convert it to varchar2 : select DBMS_LOB.SUBSTR(T1.CLOB_COL,4000,1) CLOB_COL from T1 My problem is some of my CLOBS contains more than 4000 characters. How can I display it...any idea/suggestion? thanks a lot.. I guess you could display the chunks as separate rows ? SELECT ROWNUM as chunk_no,ID, SUBSTR (t1.clob_col, (ROWNUM-1)*4000, 4000) AS chunk FROM t1 CONNECT BY (ROWNUM-1)*4000 <= LENGTH(t1.clob_col) or if there is a constraint on the maximum size a clob could be in your system you could

According to the documents I've read, the default storage for a CLOB or BLOB is inline, which means that if it is less than approx 4k in size then it will be held in the table. But when I test this on a dummy table in Oracle (10.2.0.1.0) the performance and response from Oracle Monitor (by Allround Automations) suggest that it is being held outwith the table. Here's my test scenario ... create table clobtest ( x int primary key, y clob, z varchar(100) ) ; insert into clobtest select object_id, object_name, object_name from all_objects where rownum < 10001 ; select COLUMN_NAME, IN_ROW from user

When I try to display the contents of a LOB (large object) column in SQL*Plus, it is truncated. How do I display the whole thing? SQL> set long 30000 SQL> show long long 30000 You may also need: SQL> set longchunksize 30000 Otherwise the LOB/CLOB will wrap. 来源： https://stackoverflow.com/questions/122772/how-do-i-display-the-full-content-of-lob-column-in-oracle-sqlplus
