I have a table say Table  Table_A which has a clob data column column_A. Within that column I have a record whose value is 'abc'. I want to change that value to 'cde'. I am connected to oracle 10g using Toad and SqlDeveloper. I could not find option to edit the clob column data. Please suggest me how can i edit clob column data. Any links, resources, ideas highly appreciated. Thanks in advance.

you can update a clob much like you would any other type

update your_table set your_clob = 'cde'

if this doesn't work you must have a more complicated scenario than described above.

If you use SQL Developer, updating a single field is pretty easy. Open the table, click on the Data tab, then double-click on the column you want to modify (you may have to filter out the data as needed). Make your changes, then click OK and then commit.

In Toad you can open your table in the schema browser,  double click on the CLOB cell in the data tab and it will bring up a window to edit the clob contents

you can also use the Toad keyword "edit"  on the sql editor
use it like you would a select statement

edit your_table where ....

the result grid produced by that query will be editable,  double clikc on the clob cell in the grid and it will bring up a window to edit the clob contents

In Toad when I open my table in the schema browser,  double click on the CLOB cell in the data tab and it is bringing up a window to but not allowing to edit. Please advise. Same thing happening with SQLDEVELOPER also.

perhaps you don't have update privileges on the table
