Prepared Statement Object
typedef struct sqlite3_stmt sqlite3_stmt;
An instance of this object represents a single SQL statement that has been
compiled into binary form and is ready to be evaluated.
Think of each SQL statement as a separate computer program. The
original SQL text is source code. A prepared statement object is the
compiled object code. All SQL must be converted into a prepared statement
before it can be run.
The life-cycle of a prepared statement object usually goes like
this:
- Create the prepared statement object using sqlite3_prepare_v2().
- Bind values to parameters using the sqlite3_bind_*() interfaces.
- Run the SQL by calling sqlite3_step() one or more times.
- Reset the prepared statement using sqlite3_reset() then go back to step 2.
Do this zero or more times.
- Destroy the object using sqlite3_finalize().
