Create the below table using the SQLyog ‘Create Table’ option/grid, but do not type the parentheses for the CHECK condition (i.e., type the text highlighted `val` = 1 OR `val` IS NULL ).
CREATE TABLE `test` (
`id` INT(11) UNSIGNED NOT NULL AUTO_INCREMENT,
`val` INT(11)COMMENT 'abcd' CHECK (`val` = 1 OR `val` IS NULL),
PRIMARY KEY (`id`)
) ENGINE=INNODB DEFAULT CHARSET=utf8;
NB: SQLyog encloses the column level CHECK constraint's condition in parenthesis in the query generated.
Using the ‘Alter Table’ option, replace the entire column level check condition with `val` = 1. And save the changes.
It returns the syntax error since the check condition isn’t enclosed in parenthesis.
