How to execute postgres' sql queries from batch file?

Question

I need to execute SQL from batch file. I am executing following to connect to Postgres and select data from table

C:/pgsql/bin/psql -h %DB_HOST% -p 5432 -U %DB_         


        

Answer 1

You could pipe it into psql

(
echo select * from test;
) | C:/pgsql/bin/psql -h %DB_HOST% -p 5432 -U %DB_USER% -d %DB_NAME% 

When closing parenthesis are part of the SQL query they have to be escaped with three carets.

( 
echo insert into testconfig(testid,scenarioid,testname ^^^) values( 1,1,'asdf'^^^);
) | psql -h %DB_HOST% -p 5432 -U %DB_USER% -d %DB_NAME%
