In the text that follows, the operands of the subsequent ** OP_SeekGE opcode are denoted as SeekOP.P1 through SeekOP.P4. Only ** the P1, P2 and P5 operands of this opcode are also used, and are called ** This.P1, This.P2 and This.P5. ** ** This opcode helps to optimize IN operators on a multi-column index ** where the IN operator is on the later terms of the index by avoiding ** unnecessary seeks on the btree, substituting steps to the next row ** of the b-tree instead. A correct answer is obtained if this opcode ** is omitted or is a no-op. ** ** The SeekGE.P3 and SeekGE.P4 operands identify an unpacked key which ** is the desired entry that we want the cursor SeekGE.P1 to be pointing ** to. Call this SeekGE.P3/P4 row the "target". ** ** If the SeekGE.P1 cursor is not currently pointing to a valid row, ** then this opcode is a no-op and control passes through into the OP_SeekGE. ** ** If the SeekGE.P1 cursor is pointing to a valid row, then that row ** might be the target row, or it might be near and slightly before the ** target row, or it might be after the target row. If the cursor is ** currently before the target row, then this opcode attempts to position ** the cursor on or after the target row by invoking sqlite3BtreeStep() ** on the cursor between 1 and This.P1 times. ** ** The This.P5 parameter is a flag that indicates what to do if the ** cursor ends up pointing at a valid row that is past the target ** row. If This.P5 is false (0) then a jump is made to SeekGE.P2. If ** This.P5 is true (non-zero) then a jump is made to This.P2. The P5==0 ** case occurs when there are no inequality constraints to the right of ** the IN constraint. The jump to SeekGE.P2 ends the loop. The P5!=0 case ** occurs when there are inequality constraints to the right of the IN ** operator. In that case, the This.P2 will point either directly to or ** to setup code prior to the OP_IdxGT or OP_IdxGE opcode that checks for ** loop terminate. ** ** Possible outcomes from this opcode:
      ** **
    1. If the cursor is initially not pointed to any valid row, then ** fall through into the subsequent OP_SeekGE opcode. ** **
    2. If the cursor is left pointing to a row that is before the target ** row, even after making as many as This.P1 calls to ** sqlite3BtreeNext(), then also fall through into OP_SeekGE. ** **
    3. If the cursor is left pointing at the target row, either because it ** was at the target row to begin with or because one or more ** sqlite3BtreeNext() calls moved the cursor to the target row, ** then jump to This.P2.., ** **
    4. If the cursor started out before the target row and a call to ** to sqlite3BtreeNext() moved the cursor off the end of the index ** (indicating that the target row definitely does not exist in the ** btree) then jump to SeekGE.P2, ending the loop. ** **
    5. If the cursor ends up on a valid row that is past the target row ** (indicating that the target row does not exist in the btree) then ** jump to SeekOP.P2 if This.P5==0 or to This.P2 if This.P5>0. **
