[sql] Just get column names from hive table

I know that you can get column names from a table via the following trick in hive:

hive> set hive.cli.print.header=true;
hive> select * from tablename;

Is it also possible to just get the column names from the table?

I dislike having to change a setting for something I only need once.

My current solution is the following:

hive> set hive.cli.print.header=true;
hive> select * from tablename;
hive> set hive.cli.print.header=false;

This seems too verbose and against the DRY-principle.

use desc tablename from Hive CLI or beeline to get all the column names. If you want the column names in a file then run the below command from the shell.

$ hive -e 'desc dbname.tablename;' > ~/columnnames.txt

where dbname is the name of the Hive database where your table is residing You can find the file columnnames.txt in your root directory.

$cd ~
$ls

you could also do show columns in $table or see Hive, how do I retrieve all the database's tables columns for access to hive metadata

Best way to do this is setting the below property:

set hive.cli.print.header=true;
set hive.resultset.use.unique.column.names=false;
