Polysyncronism

I have recently had the opportunity to use awk and sqlite on a project that I’m working on.

My first thought was that awk should be able to do that. I found some code that someone else did that parses quote and comma delimited.

I started off installing sqlite on cygwin.

After getting sqlite installed, I felt that I needed some test data in order to work with so I did a search and found this site:

https://www.briandunning.com/sample-data/

I grabbed the free file for testing.

wget https://www.briandunning.com/sample-data/us-500.zip

1	wget https://www.briandunning.com/sample-data/us-500.zip

The file is comma delimited file that has these fields:

First Name
Last Name
Company
Address
City
County (where applicable)
State/Province (where applicable)
ZIP/Postal Code
Phone 1
Phone 2
Email
Web

CREATE TABLE us500 (
first_name TEXT NOT NULL,
last_name TEXT NOT NULL,
company TEXT NOT NULL,
address TEXT NOT NULL,
city TEXT NOT NULL,
county TEXT NOT NULL,
state TEXT NOT NULL,
zipcode TEXT NOT NULL,
phone1 TEXT NOT NULL,
phone2 TEXT NOT NULL,
email TEXT NOT NULL,
web TEXT NOT NULL);

CREATE TABLE us500 (

first_name TEXT NOT NULL,

last_name TEXT NOT NULL,

company TEXT NOT NULL,

address TEXT NOT NULL,

city TEXT NOT NULL,

county TEXT NOT NULL,

state TEXT NOT NULL,

zipcode TEXT NOT NULL,

phone1 TEXT NOT NULL,

phone2 TEXT NOT NULL,

email TEXT NOT NULL,

web TEXT NOT NULL);

Here I used the SQLite command line to issue the command to create the table.

sqlite> CREATE TABLE us500 (
   ...> first_name TEXT NOT NULL,
   ...> last_name TEXT NOT NULL,
   ...> company TEXT NOT NULL,
   ...> address TEXT NOT NULL,
   ...> city TEXT NOT NULL,
   ...> county TEXT NOT NULL,
   ...> state TEXT NOT NULL,
   ...> zipcode TEXT NOT NULL,
   ...> phone1 TEXT NOT NULL,
   ...> phone2 TEXT NOT NULL,
   ...> email TEXT NOT NULL,
   ...> web TEXT NOT NULL);
sqlite> .tables
us500
sqlite>

sqlite> CREATE TABLE us500 (

...> first_name TEXT NOT NULL,

...> last_name TEXT NOT NULL,

...> company TEXT NOT NULL,

...> address TEXT NOT NULL,

...> city TEXT NOT NULL,

...> county TEXT NOT NULL,

...> state TEXT NOT NULL,

...> zipcode TEXT NOT NULL,

...> phone1 TEXT NOT NULL,

...> phone2 TEXT NOT NULL,

...> email TEXT NOT NULL,

...> web TEXT NOT NULL);

sqlite> .tables

us500

sqlite>

I attempted to import the csv file but got an error.

ssqlite> .mode csv
sqlite> .import us-500lf.csv us500
Error: us-500lf.csv line 2: expected 12 columns of data but found 13

ssqlite> .mode csv

sqlite> .import us-500lf.csv us500

Error: us-500lf.csv line 2: expected 12 columns of data but found 13

I can tell that the records are from a Macintosh system because the file has a carriage return record delimiter.

so I wanted to view a hexdump of the file. I used cat, tr , head and hexdump.

You can see in the HEX dump below that the file now has hex 09 line feeds.

$ cat us-500.csv | tr "\r" "\n" | head -n 3 |hexdump -C

The problem is how to handle quote comma delimited files. I did a search to see if someone already had a solution for that and found this:

AWK CSV Parser

The code contains a function called parse_csv(). You can look at the usage of the parameters on the link above. The important part is how to call this function.

{
     num_fields = parse_csv($0, csv, ",", "\"", "\"", "\n", 1);
     if (num_fields &lt; 0) {         printf "ERROR: %s (%d) -&gt; %s\n", csverr, num_fields, $0;
     } else {
         #printf "%s -&gt; ", $0;
         #printf "%s", num_fields;
         for (i = 0;i &lt; num_fields;i++) {
           fld = csv[i];
           gsub(/\"/,"",fld);
           if(i &lt; num_fields-1)
              printf "%s\t", fld;
           else
              printf "%s\n", fld;
         }
     }
 }

{

num_fields = parse_csv($0, csv, ",", "\"", "\"", "\n", 1);

if (num_fields < 0) { printf "ERROR: %s (%d) -> %s\n", csverr, num_fields, $0;

} else {

#printf "%s -> ", $0;

#printf "%s", num_fields;

for (i = 0;i < num_fields;i++) {

fld = csv[i];

gsub(/\"/,"",fld);

if(i < num_fields-1)

printf "%s\t", fld;

else

printf "%s\n", fld;

}

cat us-500.csv |tr "\r" "\n" |awk -f  parsecsv.awk >test1.pip

1	cat us-500.csv \|tr "\r" "\n" \|awk -f parsecsv.awk >test1.pip

I’m using AWK to convert the CSV file into a pipe delimited file.

I then imported the data into the database.

sqlite> select first_name,last_name from us500 limit 5;
first_name|last_name
James|Butt
Josephine|Darakjy
Art|Venere
Lenna|Paprocki

sqlite> select first_name,last_name from us500 limit 5;

first_name|last_name

James|Butt

Josephine|Darakjy

Art|Venere

Lenna|Paprocki

I’m seeing the first row has the column titles. I’ll look into how to import without that line later.
