Re: Minor systax error but not able to resolve it...

Thanks. Putting $cmd in single quote resolve the error but it generated
other error. :(

mydb=> CREATE OR REPLACE FUNCTION test_create()
RETURNS void AS
$BODY$
$cmd = "CREATE TABLE testtable(col varchar not null);";
spi_exec_query("CREATE OR REPLACE FUNCTION myfunc() RETURNS void AS
'$cmd'LANGUAGE plperl;");
spi_exec_query("SELECT myfunc();");
$BODY$
LANGUAGE 'plperl';
CREATE FUNCTION
mydb=> SELECT test_create();
ERROR: error from Perl function "test_create": error from Perl function
"myfunc": Can't locate object method "col" via package "varchar" (perhaps
you forgot to load "varchar"?) at line 1. at line 3.

this is also related to quoting?
