A package to generate SQL statements from CSV files

Generate Temp Table SQL

Generate Temp Table SQL is a Python package that generates SQL statements for creating a temporary table and inserting data from a CSV file. It's useful when you need to move data between data warehouses that are otherwise not connected, so you can download a CSV and recreate the data in the other warehouse as a temporary table from the CSV.

Features

• Load data from a CSV file
• Generate a CREATE TEMP TABLE SQL statement
• Generate INSERT INTO SQL statements for the data
• Command-line interface (CLI) for easy usage

Installation

Prerequisites

• Python 3.6 or higher
• pandas library

Installing

1. Clone the repository:

   git clone https://github.com/rywaldor/generate_temp_table_sql.git
   cd generate_temp_table_sql
   

2. Install the package locally:

   pip install -e .
   

Usage

Command-Line Interface (CLI)

After installing the package, you can use the generate-tt-sql command to generate SQL statements from a CSV file.

Basic Usage

To generate SQL statements and save them to a file:

generate-tt-sql path/to/your/file.csv

Additional Options

--o The path to the output SQL file.  Defaults to the director you call the command in.
--overwrite: Allow overwriting the output file if it exists.
--table_name: Specify the name of the temporary table to create.
--column_type: Specify the data type of the columns in the temporary table. Defaults to TEXT which works for Redshift and Snowflake. Use STRING for BigQuery.

Example

Assume you have a CSV file example.csv with the following content:

name,age,city
John,30,New York
Jane,25,Los Angeles

Run the following command to generate SQL statements:

generate-tt-sql example.csv -o output.sql --table_name my_temp_table --column_type STRING

The output.sql file will contain:

CREATE TEMP TABLE my_temp_table (
    name STRING,
    age STRING,
    city STRING
);

--Insert Data SQL:
INSERT INTO my_temp_table (name, age, city) VALUES 
    ('John', '30', 'New York'),
    ('Jane', '25', 'Los Angeles');

Running Tests

To run the tests, use the following command:
