CREATE TABLE "morse_taper_dimensions_mm" (

Question: What is the B (max) average when the C (max) is greater than 156, the taper is 1:19.231, and the D (max) is less than 34.9?
SQL: SELECT AVG("b_max") FROM "morse_taper_dimensions_mm" WHERE "c_max">156 AND "taper"='1:19.231' AND "d_max"<34.9;

Question: With a Morse Taper number less than 3 and a C (max) of 59.5 what is the total of D (max)?
SQL: SELECT COUNT("d_max") FROM "morse_taper_dimensions_mm" WHERE "morse_taper_number"<3 AND "c_max"=59.5;

Question: What's the total of the Morse Taper number when the D (max) is 20 and the B (max) greater than 94?
SQL: SELECT SUM("morse_taper_number") FROM "morse_taper_dimensions_mm" WHERE "d_max"=20 AND "b_max">94;

Question: What total D (max) has a taper of 1:20.047, and a C (max) bigger than 65.5?
SQL: SELECT SUM("d_max") FROM "morse_taper_dimensions_mm" WHERE "taper"='1:20.047' AND "c_max">65.5;

Question: What is the minimum D (max) when the Morse Taper number is less than 0?
SQL: SELECT MIN("d_max") FROM "morse_taper_dimensions_mm" WHERE "morse_taper_number"<0;
