simple-connect 1.1.0

Simplify SQL Connection for data analysis

Simplify Connection to your Database

Simple Connect allows you to securely access your database and it supports SSH Connection Currently it only supports SQL Databses.

Sample Usage

from simple_connect import connect

conn = connect.Connect('sample_credential.json', 'database_name')

sample_table = conn.query('SELECT * FROM sample_table')

Installation

pip install simple-connect

Secure your Database credentials

Simple Connect tries to find your database / ssh credentials from a json file in ".credentials" folder which is in your home directory. Example for windows, mac and linux respectively:

C:\Users\John\.credentials\sample.json

/Users/John/.credentials/sample.json

/home/John/.credentials/sample.json

Create the directory and the json file.

Json file should be in your following format:

{
  "SQL_HOST": "host_example<127.0.0.1>",
  "SQL_USER": "<username_of_your_sql>",
  "SQL_PASSWORD": "<password_of_your_sql>"
}

For SSH, you'll need to add additional keys:

{
  "SSH_USERNAME": "<ssh_username>",
  "SSH_PASSWORD": "<ssh_password>",
  "BASTION_HOST": "<sshBastion_host>"
  "SQL_HOST": "host_example<127.0.0.1>",
  "SQL_USER": "<username_of_your_sql>",
  "SQL_PASSWORD": "<password_of_your_sql>"
}

Usage

Import

from simple_connect import connect

Basic connection:

conn = connect.Connect('sample_credential.json', 'database_name')

SSH connection:

conn = connect.BastionConnect('sample_credential.json', 'database_name')

Querying

Read

Query table (returns pandas dataframe):

sample_table = conn.query('SELECT * FROM sample_table')

For Insert, Update and Delete -> Give dataframe rows that are required to update in table.

Insert

Insert new table or append to existing table:

conn.to_db(dataframe, '<table_name>')

Update

conn.update_table(dataframe, 'table_name', ['column_to_set1', 'column_to_set2', ...], ['columns_where_contition_applies', ...])

Example:

SQL:
UPDATE sample_table SET student = 'john', class = 5 WHERE id = 432 AND id_2 = 'SC'
UPDATE sample_table SET student = 'alisha', class = 5 WHERE id = 525 AND id_2 = 'SC'

Python:
conn.update_table(dataframe, 'sample_table', ['student', 'class'], ['id', 'id_2'])

Delete

conn.delete_row(dataframe, 'table_name', ['columns_where_contition_applies', ...])

Example:

conn.delete_row(dataframe, 'sample_table', ['id', 'id_2'])
