Oct 26, 2012I have a table defined where some columns are of the datatype RAW(16). In fact these are foreign keys to other tables. Our company has a policy that all primary keys are of the datatype RAW(16). Not much I can do about that.
Now I want to retrieve all columns of a certain row in that table and just visualize the foreign keys in hex format. All values are filled out nicely, except the columns with datatype RAW(16). Is there something special I have to do to retreive and display these? I defined an item as text-field for these, but this doesn't seem to be working...

Raw Datatype Changing The Case Of The Data?
Jul 31, 2013I have a table users which contains the column password and the datatype for this is raw(64) ,which will be the hashed one coming from the application. When Inserting the application is inserting with the lower case but while storing the table data is storing int the uppercase .Is it the expected behavior of this datatype. I am using Oracle 11g and attaching the ddl and dml pertaining to the column

Datatype Modification For Table With Huge Data
Aug 11, 2011Below is my requirement.
Need to change the precision of a column in a existing table. Statistics about the table
* has over 130 columns
* More than 300 million records
* Column to modify is #121 which has data
* No primary key defined
Since the column has data, it is not possible to modify with a simple Alter.
Second option - create temp column in same table, update from original, put null in original, alter, update back from temp, drop the temp column. This approach is very expensive and time consuming.
Also the Column ID needs to preserved as #121.
