postgresql - How invoke PL/pgSQL from command line instead of SQL -

-

i write pl/sql scripts using oracle , i'm trying first pl/pgsql script postgresql. example, created test.sql file.

declare     v_loc_nbr         integer; begin     v_loc_nbr := 0; end;

which try execute using command line:

\postgresql\9.3\bin\psql.exe -d postgres -f test.sql

but syntax errors like:

psql:test.sql:4: error: syntax error @ or near "v_loc_nbr"

i think problem trying execute sql when want run pl/pgsql. should command be?

i don't want explain more because erwin explained well.you need wrap sql inside do, test.sql should write this

do $$ declare     v_loc_nbr integer; begin     v_loc_nbr := 0; end; $$

and try execute \postgresql\9.3\bin\psql.exe -d postgres -f test.sql
