Compression in Teradata - forum topic by rithu

Hi experts,
I am getting a spool error while inserting records from one table to another of similar structure expect for one column where table 1 has a column with char(50) and  some 63 compression values
and table 2 has same column with char(120) with 63 compression values.(here I made sure that maximum column size here to be 7560 bytes)
 
When i tried inserting values using query insert into tab2 select top 1 * from tab1 I am getting no more spool space error.
 But I am not getting this error when tab2 has the same column datatype as that of tab1 as char(50)
Please help.
