StatementParameters class sealed

A set of values that can be used to bind parameters in a SQL query.

Parameters are placeholder values in SQL that can safely be bound to values later without a risk of SQL injection attacks. Depending on the syntax used to declare a parameter, it may make sense to pass parameters by their index or by name. The different constructors of this class can be used to control how parameters are passed.

This package supports binding int, BigInt, String, double, List<int> and null values by default. For custom values, such as those using the pointer-binding interface provided by sqlite3, CustomStatementParameter can be implemented and passed as a parameter as well.
