Why go through all of this when COPY can handle this for you? All I need to know is the syntax to tell copy that the strings are quoted by a single quote.
This might not be the quickest way, but it is a skill you'll be happy to have gained.
Perl has a class (or module) called CSV.pm, you feed it a file, and it does the rest (parsing it) and gives an array for each row. You can then alter them (however you wish) and write them to a file suitable for pg copy, or just use DBI to insert it into the PG. Which is basically an ETL (Extract, Transform, Load). I know insert is slower, but the point was to show a general way that will always for.
I need some help importing a csv file. I have been given a csv file full of data that is delimited by a comma, and the strings are delimited by a single quote. How do you write the copy statement to use a single quote delimiter? I have tried several things, but so far, no joy.
