Question 1

What SQL dialect does the output use?

Accepted Answer

The generated INSERT statements use standard SQL compatible with MySQL, PostgreSQL, SQLite, and most ANSI SQL databases. String values are single-quoted and escaped. Numeric values are unquoted. Adjust the table name and column types to match your schema.

Question 2

How are NULL values handled?

Accepted Answer

Empty CSV cells are converted to NULL in SQL output. If you want empty strings instead of NULL, wrap empty values in quotes in your CSV source data. Always review the generated SQL against your database schema before executing.

Question 3

Is batch insert more efficient than individual inserts?

Accepted Answer

Yes. A single INSERT with multiple VALUE rows is significantly faster than individual INSERT statements due to reduced network round-trips and transaction overhead. This tool generates batched INSERT statements for efficiency.
