** ^The sqlite3_vtab_distinct() interface returns an integer that is

** either 0, 1, or 2. The integer returned by sqlite3_vtab_distinct()

|

**

** ^For the purposes of comparing virtual table output values to see if the

** to be the same. In other words, the comparison operator is "IS"

|

** If a virtual table implementation is unable to meet the requirements

|
** the "orderByConsumed" flag is unset, the query planner will add extra

|
** CAPI3REF: Identify and handle IN constraints in xBestIndex
|
||||||
|
**
|
||||||
|
** This interface may only be used from within an
|
||||||
|
** [xBestIndex|xBestIndex() method] of a [virtual table] implementation.
|
||||||
|
** The result of invoking this interface from any other context is
|
||||||
|
** undefined and probably harmful.
|
||||||
|
**
|
||||||
|
** ^(A constraint on a virtual table of the form
|
||||||
|
** "[IN operator|column IN (...)]" is
|
||||||
|
** communicated to the xBestIndex method as a
|
||||||
|
** [SQLITE_INDEX_CONSTRAINT_EQ] constraint.)^ If xBestIndex wants to use
|
||||||
|
** this constraint, it must set the corresponding
|
||||||
|
** aConstraintUsage[].argvIndex to a postive integer. ^(Then, under
|
||||||
|
** the usual mode of handling IN operators, SQLite generates [bytecode]
|
||||||
|
** that invokes the [xFilter|xFilter() method] once for each value
|
||||||
|
** on the right-hand side of the IN operator.)^ Thus the virtual table
|
||||||
|
** only sees a single value from the right-hand side of the IN operator
|
||||||
|
** at a time.
|
||||||
|
**
|
||||||
|
** In some cases, however, it would be advantageous for the virtual
|
||||||
|
** table to see all values on the right-hand of the IN operator all at
|
||||||
|
** once. The sqlite3_vtab_in() interfaces facilitates this in two ways:
|
||||||
|
**
|
||||||
|
** <ol>
|
||||||
|
** <li><p>
|
||||||
|
** ^A call to sqlite3_vtab_in(P,N,-1) will return true (non-zero)
|
||||||
|
** if and only if the [sqlite3_index_info|P->aConstraint][N] constraint
|
||||||
|
** is an [IN operator] that can be processed all at once. ^In other words,
|
||||||
|
** sqlite3_vtab_in() with -1 in the third argument is a mechanism
|
||||||
|
** by which the virtual table can ask SQLite if all-at-once processing
|
||||||
|
** of the IN operator is even possible.
|
||||||
|
**
|
||||||
|
** <li><p>
|
||||||
|
** ^A call to sqlite3_vtab_in(P,N,F) with F==1 or F==0 indicates
|
||||||
|
** to SQLite that the virtual table does or does not want to process
|
||||||
|
** the IN operator all-at-once, respectively. ^Thus when the third
|
||||||
|
** parameter (F) is non-negative, this interface is the mechanism by
|
||||||
|
** which the virtual table tells SQLite how it wants to process the
|
||||||
|
** IN operator.
|
||||||
|
** </ol>
|
||||||
|
**
|
||||||
|
** ^The sqlite3_vtab_in(P,N,F) interface can be invoked multiple times
|
||||||
|
** within the same xBestIndex method call. ^For any given P,N pair,
|
||||||
|
** the return value from sqlite3_vtab_in(P,N,F) will always be the same
|
||||||
|
** within the same xBestIndex call. ^If the interface returns true
|
||||||
|
** (non-zero), that means that the constraint is an IN operator
|
||||||
|
** that can be processed all-at-once. ^If the constraint is not an IN
|
||||||
|
** operator or cannot be processed all-at-once, then the interface returns
|
||||||
|
** false.
|
||||||
|
**
|
||||||
|
** ^(All-at-once processing of the IN operator is selected if both of the
|
||||||
|
** following conditions are met:
|
||||||
|
**
|
||||||
|
** <ol>
|
||||||
|
** <li><p> The P->aConstraintUsage[N].argvIndex value is set to a positive
|
||||||
|
** integer. This is how the virtual table tells SQLite that it wants to
|
||||||
|
** use the N-th constraint.
|
||||||
|
**
|
||||||
|
** <li><p> The last call to sqlite3_vtab_in(P,N,F) for which F was
|
||||||
|
** non-negative had F>=1.
|
||||||
|
** </ol>)^
|
||||||
|
**
|
||||||
|
** ^If either or both of the conditions above are false, then SQLite uses
|
||||||
|
** the traditional one-at-a-time processing strategy for the IN constraint.
|
||||||
|
** ^If both conditions are true, then the argvIndex-th parameter to the
|
||||||
|
** xFilter method will be an [sqlite3_value] that appears to be NULL,
|
||||||
|
** but which can be passed to [sqlite3_vtab_in_first()] and
|
||||||
|
** [sqlite3_vtab_in_next()] to find all values on the right-hand side
|
||||||
|
** of the IN constraint.
