When you concatenate columns (cloumnA||','||ColumnB ||','||ColumnC), the result is a VARCHAR2, which can't be more than 4000 characters (in typical circumstances).

See this similar question for some different options.

You could use COLSEP:

set colsep ','
spool myfile.csv
select cloumnA,ColumnB,ColumnC ..... from my_tab_name;

Which will get you something like

A_value           ,B_value      ,C_value
A_value           ,B_value      ,C_value
A_value           ,B_value      ,C_value

Which most people don't like, but it doesn't have a 4000-character line limit.

If you're using SQL Developer, you can use the easy /*csv*/ hint

select /*csv*/ cloumnA,ColumnB,ColumnC ..... from my_tab_name;

And if it's possible for you to use the newer SQLcl instead of SQL*Plus, you can use set sqlformat:

set sqlformat csv
spool myfile.csv
select cloumnA,ColumnB,ColumnC ..... from my_tab_name;
