Create sqlite db python11/24/2023 Not sure what exactly changed, as it looks basically the same to me, but it works. I changed the table creation code to the following: # Create the table of pitchesĬreateTable = "CREATE TABLE IF NOT EXISTS pitches(pitch_type text, game_date text, release_speed real)"Īnd it works now. We’ll also briefly cover the creation of the sqlite database table using Python. In this article we’ll demonstrate loading data from an SQLite database table into a Python Pandas Data Frame. I tried taking the table creation out of the code entirely, per this answer, with the following code: # Import librariesĪnd still get the sqlite3.OperationalError: table pitches has no column named SL An SQLite database can be read directly into Python Pandas (a data analysis library). When I take the headers out of the csv file: SL 81.9Īnd I get the following error: sqlite3.OperationalError: table pitches has no column named SL When I have the headers in the csv, the dataframe looks like this: pitch_type game_date release_speedĪnd I get the following error: sqlite3.OperationalError: table pitches has no column named game_date I can't figure out why it's looking at the csv value as a column name, unless it thinks the first row of the csv should be the headers and is trying to match that to column names in the table? I don't think that was it either though because I tried changing the first value to an actual column name and got the same error. To interact with an SQLite database in Python you have to connect to the database, create a cursor and use the execute () function on the cursor. SL is the first value in the first row in my csv file. When I run this code, I get the following error: sqlite3.OperationalError: table pitches has no column named SL By default, the dataframe index is written as a column. The column names of the table are same as the header of the CSV file. For example, the following Python program creates a new database file pythonsqlite.db in the c:sqlitedb folder. Pass the table name and connection object inside this function. To create a database, first, you have to create a Connection object that represents the database using the connect () function of the sqlite3 module. Here's my code: # Import librariesĬ.execute("""CREATE TABLE IF NOT EXISTS pitches (ĭf.to_sql('pitches', conn, if_exists='append', index=False) Syntax: pandas.readcsv (‘filename.csv’) Write the contents to a new table- The function tosql () creates a new table from records of the dataframe. I've tried following some tutorials and the documentation but I can't figure this error out. After some searching it seems like this is possible using a pandas df. I'm trying to create a sqlite db from a csv file.
