Dear All,
suppose if there's a varchar2 column in which we have saved numbers like '1234' , '23456' ,'213456CR','4535FDR'
now from above example i need only those values which are purely numbers and i want to replace all other values with '0'
how to do it
e.g i need only 1234,1254 and so on
Please help me in this regard.
thanx in advance

Have you looked up the syntax and examples in the link that I provided? Make an attempt to solve your problem, post what you did and we will help you to work through it if you do not get it right. But put some effort in and try it for yourself.

Is this what you want?
UPDATE this_table SET
col1 = 0
WHERE col1 <contains anything but numbers>; |
