Hey Everyone,

My database is having the default characterset WE8MSWIN1252 and the value for "NLS_LENGTH_SEMANTICS" is "BYTE". I changed it to "CHAR" but nothing changed.

Thanks

UTF8 is a varying-length character set which means that each character can take from 1 to 3 bytes, so your error.
You have to change all your varchar2 column length semantics from BYTE to CHAR using "ALTER TABLE MODIFY...".

The parameter NLS_LENGTH_SEMANTICS is effective for the future tables.

But I think columns need to be empty in order to change the data type of the columns.

I have tried but i got the same error for the missing data at the time of import, the changes you said can be done only once the table import is done.

I want some which can be done at the import time.

First import the table WITHOUT the rows, then change the type, then import the rows.
This is the ONLY way.

If a table already exists and we use IGNORE=y , then rows are imported into existing tables without any errors but how to import table for the first time without rows.

I am facing this issue in the production database do you it will be good idea to tell them import without including rows and then change your data type and then again import.. Confused

Either they do that, either they are satisfied with some missing rows.

But this won't be for the single table they might have to do for the several tables, as I can not ask them simply to change the CHARACTERSET of their database that will be like ending my career. Laughing

I'll try to implement it at my end for all the existing tables in database.

Thanks

Sometimes you have to swalow the pill even if you don't like it.
As I said, if you don't want to recreate the database, this is the only direct way to do it.

This is another problem which refers to your data and we can't address not knowing them.
Try to do the import in a new empty schema and see what happens.
Also you could try to disable the constraints before the import and reenable them after.

There is no migration there, just an import, CSSCAN will give nothing.

Hi All,

The problem has been resolved, I first did the import without data bu using "ROWS=n", then I change the datatype of the column to CHAR by using "ALTER TABLE MODIFY COLUMN..." command.

Now before importing the data I disabled the constraint for the particular schema and there after issued the import command to import data and everything went well and the import was done successfully without any error.

Thanks everyone for all their efforts.

Regards
