Обсуждение: Display format for column

Hi there!

How do we format column size for displaying data in postgresql.
for example my data type for customername is varchar(100) and I want to 
display the first 25 chars.
How should I do that?

can I do something like:

psql > column customername format a25

"display" a data is a client problem only, but you can select part ofstring:
   # select substring('qwertyuiopasdfg' from 0 for 8);    substring    -----------     qwertyu     or for your case:
selectsubstring(customername from 0 for 25) FROM yourtab;
