Bulk query SQLite database over the network.
Way faster than SQLiteProxy!

go get -u github.com/assafmo/SQLiteQueryServer

This package uses github.com/mattn/go-sqlite3. Compilation errors might be resolved by reading https://github.com/mattn/go-sqlite3#compilation.

Usage of SQLiteQueryServer:
  -db string
        Filesystem path of the SQLite database
  -port uint
        HTTP port to listen on (default 80)
  -query string
        SQL query to prepare for

Note: SQLiteQueryServer is optimized for the SELECT command. Other commands such as INSERT, UPDATE, DELETE, CREATE, etc might be slow because SQLiteQueryServer doesn't use transactions (yet). Also, the response format and error messages from these commands can be odd or unexpected.

SQLiteQueryServer --db "$DB_PATH" --query "$PARAMETERIZED_SQL_QUERY" --port "$PORT"

SQLiteQueryServer --db ./db_example/ip_dns.db --query "SELECT * FROM ip_dns WHERE dns = ?" --port 8080

This will expose the ./db_example/ip_dns.db database with the query SELECT * FROM ip_dns WHERE dns = ? on port 8080.
Requests will need to provide the query parameters.

echo -e "github.com\none.one.one.one\ngoogle-public-dns-a.google.com" | curl "http://localhost:8080/query" --data-binary @-

echo -e "$QUERY1_PARAM1,$QUERY1_PARAM2\n$QUERY2_PARAM1,$QUERY2_PARAM2" | curl "http://$ADDRESS:$PORT/query" --data-binary @-

curl "http://$ADDRESS:$PORT/query" -d "$PARAM_1,$PARAM_2,...,$PARAM_N"

• Request must be a HTTP POST to "http://$ADDRESS:$PORT/query".
• Request body must be a valid CSV.
• Request body must not have a CSV header.
• Each request body line is a different query.
• Each param in a line corresponds to a query param (a question mark in the query string).

echo -e "github.com\none.one.one.one\ngoogle-public-dns-a.google.com" | curl "http://localhost:8080/query" --data-binary @-

• If response status is 200 (OK), response is a JSON array (Content-Type: application/json).
• Each element in the array:
  • Is a result of a query
  • Has an "in" fields which is an array of the input params (a request body line).
  • Has an "headers" fields which is an array of headers of the SQL query result.
  • Has an "out" field which is an array of arrays of results. Each inner array is a result row.
• Element #1 is the result of query #1, Element #2 is the result of query #2, and so forth.
