建表语句：

CREATE TABLE table_test (
id bigint unsigned NOT NULL AUTO_INCREMENT COMMENT 'auto id',
column1 varchar(50) NOT NULL DEFAULT '' COMMENT 'column1',
column2 varchar(50) NOT NULL DEFAULT '' COMMENT 'column2',
column3 varchar(150) NOT NULL DEFAULT '' COMMENT 'column3',
column4 varchar(255) NOT NULL DEFAULT '' COMMENT 'column4',
column5 varchar(20) NOT NULL DEFAULT '' COMMENT 'column5',
ctime datetime NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT 'ctime',
mtime datetime NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT 'mtime',
PRIMARY KEY (id),
KEY idx_column2 (column2),
KEY idx_column3 (column3)
) ENGINE = InnoDB DEFAULT CHARSET = utf8mb4 COLLATE = utf8mb4_unicode_ci COMMENT = 'this is a test table';
