Build Identifier:

Mserver gets an assertion error while optimizing in the SQL layer a complex SELECT query with comparisons, AND, OR, BETWEEN and IN operators.

Reproducible: Always

Steps to Reproduce:

  1. CREATE TABLE tab0(pk INTEGER PRIMARY KEY, col0 INTEGER, col1 FLOAT, col2 TEXT, col3 INTEGER, col4 FLOAT, col5 TEXT);
  2. SELECT pk FROM tab0 WHERE ((col1 <= 601.41 AND (((col0 IS NULL AND (col3 > 768 OR col3 > 89)) AND ((col0 BETWEEN 996 AND 960 OR col4 < 664.34 AND col1 >= 445.23 AND ((col3 > 823 AND ((col3 >= 663)))) AND col0 > 883 AND col4 >= 247.43 OR (col0 = 115))) AND (((col0 > 941 AND col1 > 559.36)) AND (col4 IS NULL OR col0 > 583 AND (col3 > 927) OR col1 > 616.82 OR col0 < 35 OR (col0 > 688 AND (((col0 < 595 AND (col4 > 228.67) OR (col0 = 651) AND (((col1 = 509.82))) AND ((((col0 > 416))) OR col1 > 84.53 AND col1 < 285.58 AND col0 IS NULL AND col1 < 672.99 OR col3 = 682 AND col0 < 708) AND ((((col0 IS NULL))) OR col0 IS NULL OR col3 < 153 AND (col0 BETWEEN 36 AND 310 AND (col1 = 774.43) OR col4 < 876.56 AND col3 < 539 AND (col0 BETWEEN 177 AND 119) AND col3 < 820 OR col3 >= 529 AND col3 >= 268 OR (col3 > 749) AND col3 BETWEEN 511 AND 711 AND (((col3 >= 337) OR col0 IS NULL AND col4 > 965.36 AND ((col3 < 227) AND (col4 < 99.43 AND col3 > 263 OR col3 > 830 AND ((((((col1 < 984.99)))) AND ((col0 > 236 OR col0 > 475 AND col0 >= 150 AND (col3 >= 78) AND (((col4 > 135.83))))))) OR col0 <= 331 AND col1 >= 757.56 OR (col0 < 776) OR ((col1 >= 625.78)) AND col0 IS NULL OR (col3 >= 758 OR (col0 < 140)) AND col3 IS NULL)) AND ((col0 < 107 OR (col3 < 647))) AND (col4 <= 35.83) AND ((((col3 > 959))) OR (col3 >= 425 OR col3 <= 824 AND col1 > 223.73 AND (col4 >= 408.86 AND col4 > 641.19 OR col4 <= 813.85 OR (col0 IS NULL)) AND (((col4 > 587.71))) AND (((col0 > 214 AND col3 > 316 AND ((col0 > 212) AND (col3 >= 606 AND col0 <= 213 OR col3 IS NULL AND col0 <= 529 AND ((col0 = 74))) OR ((((col3 BETWEEN 45 AND 763) OR col4 > 137.10))) AND (col1 < 931.44 AND col3 > 344) AND (col3 > 290 OR col4 < 663.75 AND col4 <= 216.96 AND col3 < 982) AND col3 > 240 AND col1 >= 153.46 OR (col0 IN (540,371,358) AND col0 BETWEEN 299 AND 738) AND col0 < 694 AND ((col3 < 378 AND col3 < 506 AND col0 IS NULL) AND col1 < 145.44) OR (col0 > 687 AND col0 < 667) OR (col0 = 412 OR (((((col0 < 136) AND col3 < 47)))) AND (col3 >= 720)) OR (col3 = 806 AND ((col3 > 988) AND ((((col1 < 786.49)) OR col3 = 752) AND col0 < 740))) AND col0 = 203 OR col0 <= 262 OR ((col3 <= 964 AND col1 < 173.79)) OR col0 > 763 AND (col3 >= 187) OR col0 > 767 AND (col1 <= 872.2) AND col0 = 326 OR (col4 = 57.9) OR col0 > 930 OR col1 < 773.31 AND (col0 >= 394) AND (col0 > 926) AND (col0 IN (305,760,124,899) OR col1 IN (71.18,407.37) AND (((col0 < 533) OR (((col4 > 241.99))) AND col1 > 746.98)))) AND col4 < 802.32 AND ((col0 > 531)) AND col0 < 58) OR col0 IS NULL)) AND col0 < 775))) AND ((col0 < 647 AND col4 <= 907.73) OR (col0 = 99))) AND (col3 > 388 AND (((col0 < 109 AND col0 = 535 AND col3 < 959 OR ((col4 >= 617.70)))))) OR ((((col0 > 95) AND (((col0 < 247 OR col3 > 685 OR (col1 > 477.89 AND col1 > 239.93 OR col0 IS NULL OR col0 >= 641 OR col1 >= 893.3 AND (col3 = 72 AND col0 > 666 AND col3 > 17) AND (col4 BETWEEN 259.28 AND 405.64) AND col3 <= 829 OR col3 IS NULL AND (col1 < 228.68)))))) OR col0 >= 729 OR col0 < 431) AND ((col0 IS NULL))) AND col3 IN (779,539,505,633,380) AND (col3 > 895) AND col1 < 604.14 OR (col0 > 626 AND ((col0 IS NULL AND (((((col4 <= 777.85) AND col0 > 388) OR col0 >= 30))) OR (col0 IS NULL) OR col0 < 692 OR col0 <= 368 OR col3 > 698 OR col3 > 349 AND (((col0 < 303)) OR (col0 = 191) AND col1 IN (108.43) AND (col4 < 816.73)))) OR col0 < 45) OR col0 <= 900 OR col0 < 218 OR (col1 > 472.9 AND (col3 > 800) OR (col3 IN (918)) AND (col3 = 813) OR col1 IS NULL OR ((col1 <= 997.17) AND ((col1 > 808.22 AND (col1 > 539.58 OR col3 IS NULL)) AND (((col4 < 173.56)))))) AND col1 < 91.27 OR col0 > 696)) OR (col3 >= 50) AND (((col0 < 609))) AND col3 < 295)) AND col0 < 400 AND col3 > 267) OR col3 > 157 AND col3 <= 642 OR (col0 = 209) AND col0 > 921 AND col1 > 587.17 OR col0 < 950) AND col0 > 805 OR col3 >= 829 AND ((((col3 >= 214)))) OR ((col0 > 744 AND col1 < 102.6 AND ((col3 <= 779)) AND (((((col3 < 876))))) AND col3 >= 707) AND (col3 < 265)))))) AND (col1 < 985.78) OR col4 BETWEEN 314.64 AND 482.24));

Expected Results:

fixed by increasing the allowed calls to _rel_optimizer, ie larger queries may require some more optimization rounds.
