How to insert multiple rows in SQLite?
Here's the concise command to insert multiple rows in SQLite:
Rename table_name
, column1
, column2
, and the row_value
s with your specific table and data.
Doing mass inserts? Wrap the insert commands within a transaction for turbo-charged performance!
Performing batch inserts this way is like giving SQLite a nitrous boost!
Handle with care: Legacy SQLite versions
Rocking an older SQLite, pre-3.7.11? Fear not! Use the UNION ALL SELECT
command for multiple inserts:
Remember, kids, in a UNION
sequence, aliases are for the cool cats in the first SELECT
only!
Optimize performance: Fast AND Furious
Transactions: The need-for-speed trick
Wrap your inserts in a single transaction to reduce disk I/O and watch SQLite do its Fast & Furious impression.
Finish the transaction with a COMMIT—No racer leaves before the race is finished!
Write-Ahead Logging (WAL): Double lane highway
