Home -> Community -> Mailing Lists -> Oracle-L -> Spooling to a flat file via SQL*Plus
I need to chang a column in an existing table from varchar2(2000) instead
to varchar2(255).
I'm to truncate any data that exists that is longer than 255.
I renamed the original table to old_table. I created a new table with the
same definitions as
old_table except made the single column that was varchar2(2000) is now
varchar2(255).
I want to spool the data to a flat file in comma-delimited form. I only
want to spool out 255
characters of the column in question. Then I'll just load it back in
using SQL*Loader.
I haven't done this for a long time and I can't remember all the sql*plus
commands to
set up the output properly so that the lines can wrap, etc. Also, I'm not
sure how to tell it
to only list 255 characters of the 2000 character column in the output
file.
I know I can spend some time looking this up in my docs but it's a terrible
day today with
a lot of fires burning in various directions.
I'd appreciate it if some kind sole could help me out with the commands to
spool this
out properly.

Name Null? Type ----------------------------------------- -------- ---------------------------- KS_EXPERIENCEID NOT NULL NUMBER(38) EXP_NOTES VARCHAR2(2000) EXP_QA_STATE VARCHAR2(100) TEMP_RN CHAR(1) EXP_REVIEW_NEEDED NOT NULL CHAR(1)
In everlasting gratitude,
Cherie
