2236 ** This function is used by the implementation of the IN (...) operator. -

2237 ** The pX parameter is the expression on the RHS of the IN operator, which -

2238 ** might be either a list of expressions or a subquery. -

2239 ** -

2240 ** The job of this routine is to find or create a b-tree object that can -

2241 ** be used either to test for membership in the RHS set or to iterate through -

2242 ** all members of the RHS set, skipping duplicates. -

2243 ** -

2244 ** A cursor is opened on the b-tree object that is the RHS of the IN operator -

2245 ** and pX->iTable is set to the index of that cursor. -

2246 ** -

2247 ** The returned value of this function indicates the b-tree type, as follows: -

2248 ** -

2249 ** IN_INDEX_ROWID - The cursor was opened on a database table. -

2250 ** IN_INDEX_INDEX_ASC - The cursor was opened on an ascending index. -

2251 ** IN_INDEX_INDEX_DESC - The cursor was opened on a descending index. -

2252 ** IN_INDEX_EPH - The cursor was opened on a specially created and -

2253 ** populated epheremal table. -

2254 ** IN_INDEX_NOOP - No cursor was allocated. The IN operator must be -

2255 ** implemented as a sequence of comparisons. -

2256 ** -

2257 ** An existing b-tree might be used if the RHS expression pX is a simple -

2258 ** subquery such as: -

2259 ** -

2260 ** SELECT <column1>, <column2>... FROM <table> -

2261 ** -

2262 ** If the RHS of the IN operator is a list or a more complex subquery, then -

2263 ** an ephemeral table might need to be generated from the RHS and then -

2264 ** pX->iTable made to point to the ephemeral table instead of an -

2265 ** existing table. -

2266 ** -

2267 ** The inFlags parameter must contain, at a minimum, one of the bits -

2268 ** IN_INDEX_MEMBERSHIP or IN_INDEX_LOOP but not both. If inFlags contains -

2269 ** IN_INDEX_MEMBERSHIP, then the generated table will be used for a fast -

2270 ** membership test. When the IN_INDEX_LOOP bit is set, the IN index will -

2271 ** be used to loop over all values of the RHS of the IN operator. -

2272 ** -

2273 ** When IN_INDEX_LOOP is used (and the b-tree will be used to iterate -

2274 ** through the set members) then the b-tree must not contain duplicates. -

2275 ** An epheremal table will be created unless the selected columns are guaranteed -

2276 ** to be unique - either because it is an INTEGER PRIMARY KEY or due to -

2277 ** a UNIQUE constraint or index. -

2278 ** -

2279 ** When IN_INDEX_MEMBERSHIP is used (and the b-tree will be used -

2280 ** for fast set membership tests) then an epheremal table must -

2281 ** be used unless <columns> is a single INTEGER PRIMARY KEY column or an -

2282 ** index can be found with the specified <columns> as its left-most. -

2283 ** -

2284 ** If the IN_INDEX_NOOP_OK and IN_INDEX_MEMBERSHIP are both set and -

2285 ** if the RHS of the IN operator is a list (not a subquery) then this -

2286 ** routine might decide that creating an ephemeral b-tree for membership -

2287 ** testing is too expensive and return IN_INDEX_NOOP. In that case, the -

2288 ** calling routine should implement the IN operator using a sequence -

2289 ** of Eq or Ne comparison operations. -

2290 ** -

2291 ** When the b-tree is being used for membership tests, the calling function -

2292 ** might need to know whether or not the RHS side of the IN operator -

2293 ** contains a NULL. If prRhsHasNull is not a NULL pointer and -

2294 ** if there is any chance that the (...) might contain a NULL value at -

2295 ** runtime, then a register is allocated and the register number written -

2296 ** to *prRhsHasNull. If there is no chance that the (...) contains a -

2297 ** NULL value, then *prRhsHasNull is left unchanged. -

2298 ** -

2299 ** If a register is allocated and its location stored in *prRhsHasNull, then -

2300 ** the value in that register will be NULL if the b-tree contains one or more -

2301 ** NULL values, and it will be some non-NULL value if the b-tree contains no -

2302 ** NULL values. -

2303 ** -

2304 ** If the aiMap parameter is not NULL, it must point to an array containing -

2305 ** one element for each column returned by the SELECT statement on the RHS -

2306 ** of the IN(...) operator. The i'th entry of the array is populated with the -

2307 ** offset of the index column that matches the i'th column returned by the -

2308 ** SELECT. For example, if the expression and selected index are: -

2309 ** -

2310 ** (?,?,?) IN (SELECT a, b, c FROM t1) -

2311 ** CREATE INDEX i1 ON t1(b, c, a); -

2312 ** -

2313 ** then aiMap[] is populated with {2, 0, 1}. -
