Re: create batch script to import into postgres tables

>>psql -d production  -U postgres -c 'select count(*) from cell_per';
Null display is "NULL".
  count
-------
    68
(1 row)

you can do this once you are in psql. But if you are running from shell script, it will be an error

>>What error messages do you get?
my shell script is:@echo off C:\Program Files\PostgreSQL\11\bin\psql -U PSmasteruser  -d PSCIDR -h hostname.amazonaws.com -p 5432 -c "select count(*) from tableA;"
pause
the error I have is 'C:\Program' is not recognized as an internal or external command, operable program or batch file.
I even surround the path in quotes because of space(dot)(at)echo off cmd /c ""C:\Program Files\PostgreSQL\11\bin\psql" -U PSmasteruser -d PSCIDR -h hostname.amazonaws.com -p 5432 -c "select count(*) from tableA;"
pause
error is: 'C:\Program Files\PostgreSQL\11\bin\psql: illegal option -- u
when I put -P Password123 (or fully qualified password=Password123)
it gives me another error "pset: unknow option: Password123psql: could not set printing parameter "Password123"
I can connect from psql shell fine when it prompt hostname, username (but connect to postgres not to PSmasteruser, PSmasteruser username set up for aws maintenance postgres database, someone did, not me and the password is same on both).  Once I'm in psql and I can change to PSCIDR instance fine and run select count(*) from tableA;

The above should be -f import.sql. AFAIK there is no -i for psql, so
that should be failing.

psql -d production  -U postgres -c 'select count(*) from cell_per';
Null display is "NULL".
  count
-------
    68
(1 row)

psql -d production  -U postgres -c 'select count(*) from cell_per'
Null display is "NULL".
  count
-------
    68

psql -d production  -U postgres -c 'select count(*) from cell_per;'
Null display is "NULL".
  count
-------
    68
