Application
After downloading the zip files and unzipping them I need to rework the files so they can be loaded into postgreSQL
eyanosch@ab201:~$ cat application.txt | sed "s/ *//g" | sed "s/\t/ /g"
- pulls up information, removes the spaces, and removes the tabs. Adds a space inbetween each column
cat application.txt | sed "s/. /&,/g"| sed "s/ *//g" | sed "s/\t/ /g"
eyanosch@ab201:~$ cat application.txt | sed "s/ *//g" | sed "s/\t/ /g" | sed "s/ /' /g" | sed "s/. /&'/g" | sed "s/ /,&/g" | sed "s/\r$/'/g" | sed "s/^/&'/g" | sed "s//null/g"
I had to add ' behind and infront of every character and then the empty spaces that were I replaced with the word null
cat application.txt | sed "s/ *//g" | sed "s/\t/ /g" | sed "s/ /' /g" | sed "s/. /&'/g" | sed "s/ /,&/g" | sed "s/\r$/');/g" | sed "s/^/&'/g" | sed "s//null/g" |sed "s/^/insert into Application(ApplNo, ApplType, SponsorApplicant, MostRecentLabelAvailableFlag, CurrentPatentFlag, ActionType, Chemical_Type, Ther_Potential, Orphan_Code) values (/g" | sed "1D" > ~/public_html/application.sql.txt
This should give the proper syntax for adding from the database the SQL
Product
cat Product.txt | sed "s/'/\"/g" | sed "s/ *//g" | sed "s/\t/ /g" | sed "s/ /' /g" | sed "s/. /&'/g" | sed "s/ /,&/g" | sed "s/\r$/');/g" | sed "s/^/&'/g" | sed "s//null/g" | sed "s/^/insert into product(ApplNo, ProductNo, Form, Dosage, productMktStatus, TECode, ReferenceDrug, drugname, activeingred) values (/g" | sed "1D" > ~/public_html/Product.sql.txt
Apply the same principle but there were 's within the text so I changed them into " and replaced them with null
Ran the program in SQL:
Query returned successfully: one row affected, 4916 ms execution time.
#1
create table Application(ApplNo varchar, ApplType varchar, SponsorApplicant varchar, MostRecentLabelAvailableFlag boolean, CurrentPatentFlag boolean, ActionType varchar, Chemical_Type varchar, Ther_Potential varchar, Orphan_Code varchar)
create table product(ApplNo int, ProductNo int, Form varchar, Dosage varchar, productMktStatus varchar, TECode varchar, ReferenceDrug varchar, drugname varchar, activeingred varchar)
#2
cat application.txt | sed "s/ *//g" | sed "s/\t/ /g" | sed "s/ /' /g" | sed "s/. /&'/g" | sed "s/ /,&/g" | sed "s/\r$/');/g" | sed "s/^/&'/g" | sed "s//null/g" |sed "s/^/insert into Application(ApplNo, ApplType, SponsorApplicant, MostRecentLabelAvailableFlag, CurrentPatentFlag, ActionType, Chemical_Type, Ther_Potential, Orphan_Code) values (/g" | sed "1D" > ~/public_html/application.sql.txt
cat Product.txt | sed "s/'/\"/g" | sed "s/ *//g" | sed "s/\t/ /g" | sed "s/ /' /g" | sed "s/. /&'/g" | sed "s/ /,&/g" | sed "s/\r$/');/g" | sed "s/^/&'/g" | sed "s//null/g" | sed "s/^/insert into product(ApplNo, ProductNo, Form, Dosage, productMktStatus, TECode, ReferenceDrug, drugname, activeingred) values (/g" | sed "1D" > ~/public_html/Product.sql.txt
#3
wc application.txt
Results: 19757 147418 1616281 application.txt
wc Product.txt
Results: 32796 369649 2858064 Product.txt
19757 and 32796 records in each respective file
#4
select count(*) from application
select count(*) from product
both give the number of records in each table
