** CAPI3REF: Change The EXPLAIN Setting For A Prepared Statement
** METHOD: sqlite3_stmt
**
** The sqlite3_stmt_explain(S,E) interface changes the EXPLAIN
** setting for [prepared statement] S. If E is zero, then S becomes
** a normal prepared statement. If E is 1, then S behaves as if
** its SQL text began with "[EXPLAIN]". If E is 2, then S behaves as if
** its SQL text began with "[EXPLAIN QUERY PLAN]".
**
** Calling sqlite3_stmt_explain(S,E) might cause S to be reprepared.
** SQLite tries to avoid a reprepare, but a reprepare might be necessary
** on the first transition into EXPLAIN or EXPLAIN QUERY PLAN mode.
**
** Because of the potential need to reprepare, a call to
** sqlite3_stmt_explain(S,E) will fail with SQLITE_ERROR if S cannot be
** reprepared because it was created using [sqlite3_prepare()] instead of
** the newer [sqlite3_prepare_v2()] or [sqlite3_prepare_v3()] interfaces and
** hence has no saved SQL text with which to reprepare.
**
** Changing the explain setting for a prepared statement does not change
** the original SQL text for the statement. Hence, if the SQL text originally
** began with EXPLAIN or EXPLAIN QUERY PLAN, but sqlite3_stmt_explain(S,0)
** is called to convert the statement into an ordinary statement, the EXPLAIN
** or EXPLAIN QUERY PLAN keywords will still appear in the sqlite3_sql(S)
** output, even though the statement now acts like a normal SQL statement.
**
** This routine returns SQLITE_OK if the explain mode is successfully
** changed, or an error code if the explain mode could not be changed.
** The explain mode cannot be changed while a statement is active.
** Hence, it is good practice to call [sqlite3_reset(S)]
** immediately prior to calling sqlite3_stmt_explain(S,E).

** CAPI3REF: Database Connection Client Data
** METHOD: sqlite3
**
** These functions are used to associate one or more named pointers
** with a [database connection].
** A call to sqlite3_set_clientdata(D,N,P,X) causes the pointer P
** to be attached to [database connection] D using name N. Subsequent
** calls to sqlite3_get_clientdata(D,N) will return a copy of pointer P
** or a NULL pointer if there were no prior calls to
** sqlite3_set_clientdata() with the same values of D and N.
** Names are compared using strcmp() and are thus case sensitive.
**
** If P and X are both non-NULL, then the destructor X is invoked with
** argument P on the first of the following occurrences:
** <ul>
** <li> An out-of-memory error occurs during the call to
** sqlite3_set_clientdata() which attempts to register pointer P.
** <li> A subsequent call to sqlite3_set_clientdata(D,N,P,X) is made
** with the same D and N parameters.
** <li> The database connection closes. SQLite does not make any guarantees
** about the order in which destructors are called, only that all
** destructors will be called exactly once at some point during the
** database connection closing process.
** </ul>
**
** SQLite does not do anything with client data other than invoke
** destructors on the client data at the appropriate time. The intended
** use for client data is to provide a mechanism for wrapper libraries
** to store additional information about an SQLite database connection.
**
** There is no limit (other than available memory) on the number of different
** client data pointers (with different names) that can be attached to a
** single database connection. However, the implementation is optimized
** for the case of having only one or two different client data names.
** Applications and wrapper libraries are discouraged from using more than
** one client data name each.
**
** There is no way to enumerate the client data pointers
** associated with a database connection. The N parameter can be thought
** of as a secret key such that only code that knows the secret key is able
** to access the associated data.
**
** Security Warning: These interfaces should not be exposed in scripting
** languages or in other circumstances where it might be possible for an
** an attacker to invoke them. Any agent that can invoke these interfaces
** can probably also take control of the process.
**
** Database connection client data is only available for SQLite
** version 3.44.0 ([dateof:3.44.0]) and later.
