SQLITE3_FINALIZE(3)        Library Functions Manual        SQLITE3_FINALIZE(3)

NAME
     sqlite3_finalize - Destroy A Prepared Statement Object

SYNOPSIS
     int
     sqlite3_finalize(sqlite3_stmt *pStmt);

DESCRIPTION
     The sqlite3_finalize() function is called to delete a prepared statement.
     If the most recent evaluation of the statement encountered no errors or
     if the statement is never been evaluated, then sqlite3_finalize() returns
     SQLITE_OK.  If the most recent evaluation of statement S failed, then
     sqlite3_finalize(S) returns the appropriate error code or extended error
     code.

     The sqlite3_finalize(S) routine can be called at any point during the
     life cycle of prepared statement S: before statement S is ever evaluated,
     after one or more calls to sqlite3_reset(), or after any call to
     sqlite3_step() regardless of whether or not the statement has completed
     execution.

     Invoking sqlite3_finalize() on a NULL pointer is a harmless no-op.

     The application must finalize every prepared statement in order to avoid
     resource leaks.  It is a grievous error for the application to try to use
     a prepared statement after it has been finalized.  Any use of a prepared
     statement after it has been finalized can result in undefined and
     undesirable behavior such as segfaults and heap corruption.
