Importing Historical Stock Data into MySQL

When integrating historical stock prices into a MySQL database, follow these steps:

  • Data Source: Obtain historical financial data, often available as CSV files, from brokers like Interactive Brokers.

  • CSV File Structure: Typically includes columns for the date and index value. Example file named ABC.csv.

  • MySQL Command:

    • Use LOAD DATA INFILE to import CSV data into a MySQL table.
    • Specify the file path on your local machine.
    • Assign data to the target table, e.g., table ABC.

  • File Format Considerations:

    • Ensure fields (date, index value) are comma and space-separated.
    • Data entries (table rows) should be separated by a new line.
    • If the CSV includes a header row, indicate to ignore it during import.

This approach ensures proper alignment and accurate data entry within MySQL, allowing seamless data analysis.
