Table: factor_x_clotting
Columns: condition
prothrombin_time
partial_thromboplastin_time
bleeding_time
platelet_count

Question: In which condition(s) is bleeding time prolonged and prothrombin time unaffected?
SQL: SELECT "condition" FROM factor_x_clotting WHERE "bleeding_time" = 'Prolonged' AND "prothrombin_time" = 'Unaffected'

Question: How many entries for prothrombin time are there where platelet count is "decreased or unaffected"?
SQL: SELECT COUNT("prothrombin_time") FROM factor_x_clotting WHERE "platelet_count" = 'Decreased or unaffected'

Question: How is the bleeding time wherein platelet count is decreased and prothrombin time is unaffected?
SQL: SELECT "bleeding_time" FROM factor_x_clotting WHERE "platelet_count" = 'Decreased' AND "prothrombin_time" = 'Unaffected'

Question: What are all the possible bleeding time results where prothrombin time and platelet count are both unaffected?
SQL: SELECT "bleeding_time" FROM factor_x_clotting WHERE "prothrombin_time" = 'Unaffected' AND "platelet_count" = 'Unaffected'
