INSERT INTO t0 VALUES ( -83 ) , ( ATAN ( -89 LIKE EXISTS ( SELECT ROW_NUMBER ( ) OVER ( PARTITION BY c51 ORDER BY CASE c51 WHEN -107 THEN COUNT( DISTINCT c51 , + TRIM( TRAILING c51 FROM '/{;sxMhm&X$8fg7_ga#RG+7,>%)qs`b-Z7_\\><_k\'ML' ) NOT IN ( RAND ( ) NOT BETWEEN 69 AND -122 ) ) - - COS ( t0 . c51 ) ELSE 39 END IS TRUE ) NOT IN ( 107 , 15 , 57 ) AS c1 ) ) ) ;
