Hello,
running the below statement does not work,

update table set col1 = col1 || 'X' ;

col1 is of CHAR datatype.

the error i'm getting is " value too large". i understand CHAR allocates the specified length as defined. would append not work at all??

could someone please help.

you need to first trim off the trailing spaces...

note: your columns should eventually be in VARCHAR2 instead of CHAR ...

update table set col1 = trim(col1) || 'X' ;

You can also use

update table set col1 = trim(rtrim(col1)) || 'X' ;

anumoses,
" What is the length of col1? Make sure its greater than col1|| 'X'  "

That is impossible!
Col1 is char, so col1||X will always be len(col1) + 1!
Hence TRIM proposed by Angel.

But if col1 is full, then the statement wills till fail.
