如何使用查询构建在Laravel中执行WHERE NOT

Question

Laravel query build has many where options, but I could not found a way to describe fields type timestamp that are not null but have an invalid value. eg: 0000-00-00 00:00:00

whereNull() are not working since it is not null

whereNot() is treated as a invalid field not

I want to use the native MySQL query NOT field since it match with "empty" values like 0000-00-00 00:00:00

Then, you will have to query it with IS NULL option. Check the ex :

SELECT * FROM `tablename` WHERE `columnname` IS NULL LIMIT 0 , 30

See if the following helps

$table->date('colname')->nullable(); 

$table->date('colname')->notnullable();
