Prepared Statement Object

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:

  1. Create the prepared statement object using sqlite3_prepare_v2().
  2. Bind values to parameters using the sqlite3_bind_*() interfaces.
  3. Run the SQL by calling sqlite3_step() one or more times.
  4. Reset the prepared statement using sqlite3_reset()
