Hi,
I have 2 tables
tab1 (col1 varchar2(10) --have some records like 123.45,4566.34
tab2 (col1 number)
Now,how to insert into tab2 from tab1.
i used insert into tab1 select * from tab2 which gives me ora-01722 invalid number.
How can i transfer the data.
I cannot change the datatype of tab2 (col1 number).
There is no precision defined for this column
Is there any other way like rounding off or something
