![]() Second, use the following CREATE TABLE statement to create the table cities. DROP TABLE IF EXISTS cities Code language: SQL (Structured Query Language) ( sql ) In the second scenario, the table is already available in the database and you just need to import the data.įirst, drop the cities table that you have created. SELECT name,Ĭities Code language: SQL (Structured Query Language) ( sql ) To view the data of the cities table, you use the following SELECT statement. ) Code language: SQL (Structured Query Language) ( sql ) schema to display the structure of the cities table. To verify the import, you use the command. import FILE TABLE to import the data from the city.csv file into the cities table. ![]() To import the c:\sqlite\city.csv file into the cities table:įirst, set the mode to CSV to instruct the command-line shell program to interpret the input file as a CSV file. We will import a CSV file named city.csv with two columns: name and population. Second, the sqlite3 tool import data from the second row of the CSV file into the table.The sqlite3 tool uses the first row of the CSV file as the names of the columns of the table. First, the sqlite3 tool creates the table.In the first scenario, you want to import data from CSV file into a table that does not exist in the SQLite database. Importing a CSV file into a table using sqlite3 tool Python | Difference between Python 2.x and Python 3.Summary: in this tutorial, you will learn various ways to import CSV data into an SQLite table using sqlite3 and SQLite Studio tools. ![]() Save my name, email, and website in this browser for the next time I comment. Your email address will not be published. Student.to_sql('studentInfo', connection, if_exists='replace', index=False)Ĭurs.execute('select * from studentInfo') " (name text, gender text, age integer,course text, branch text)") ![]() Close the connection using clase() method of connection object.Ĭonnection = sq.connect('information.db')Ĭurs.execute("create table if not exists studentInfo" +.Syntax: DataFrame.to_sql(table_name, connection_object, if_exists, index) It can either raise an error (fail), append new values, or replace the existing table. Additionally, the if_exists parameter specifies the behavior in case the table name is already being used. Simply toggle the index parameter to False in order to remove this column. By default, the dataframe index is written as a column. The column names of the table are the same as the header of the CSV file. Pass the table name and connection object inside this function. The function to_sql() creates a new table from records of the dataframe. Write the contents to a new table using to_sql() method of dataframe.Import CSV file using read_csv() method of pandas.Syntax: cursor_object.execute("Sql Query") Create a new table by executing create SQL query using execute() method of cursor object.Create a cursor object using the cursor() method of a connection object.Make a connection object with the existing database or create a new database and connect it using connect() class of sqlite3 module.Now, Let’s see the approach to import CSV file data into an SQLite database table using Python. Pandas is fast and it has high performance & productivity for users. It is mainly popular for importing and analyzing data much easier. It is a Python package that offers various data structures and operations for manipulating numerical data and time series. Pandas is an open-source library that is built on top of the NumPy library. It is the most used database engine on the world wide web. SQLite is a self-contained, high-reliability, embedded, full-featured, public-domain, SQL database engine. Sqlite3 module is used to access SQLite databases in Python. Now, For solving this requirement we will be using two modules: sqlite3 and pandas. In this post, we will see how to import CSV file data into an SQLite database table using Python. ![]()
