CREATE TEMPORARY TABLE v0 ( v2 INT AS ( ( USER ( ) LIKE 'x' ) ) , v1 INT ) ; |
SELECT SECOND ( least ( 88873112.000000 , 'x' ) ) FROM v0 ORDER BY UPPER ( v2 ) ; |
SELECT v1 FROM v0 AS v0 ORDER BY v1 ; |
SHOW VARIABLES WHERE unhex ( STR_TO_DATE ( '' , 24 ) ) / 73964752.000000 ; |
ALTER TABLE v0 ADD v0 CHAR DEFAULT 'x' NOT NULL ; |
CREATE INDEX v3 ON v0 ( v3 DESC ) ; |
