CREATE TABLE table_name_45 (snatch INT, total__kg_ VARCHAR, clean_ VARCHAR, _jerk VARCHAR)

WHAT IS THE SNATCH WITH TOTAL KG SMALLER THAN 318, AND CLEAN JERK LARGER THAN 175?
SELECT MIN(snatch) FROM table_name_45 WHERE total__kg_ < 318 AND clean_ & _jerk > 175
SELECT MIN("snatch") FROM "table_name_45" WHERE "total__kg_" < 318 AND "clean_" & "_jerk" > 175
