I m sorry If anyone has already asked this Q earlier
I wanted to know
Q1. Whether I can have another key on which the table is indexed even though i have a primary key..Then how would the data be accessed according to primary key or the indexed key of my choice or i can index as per my choice ( primary / index key)?
Q2. If possible can anybody tell me how to get the script given in the e-book of Postresql be interpreted in Perl i.e
perl <name of file>
gives an error that Pg is not connected to Dbase
