You want to find the names of the constraints in a table in Oracle. Example We want to display the names of the constraints in the table student. Solution SELECT constraint_name, constraint_type, table_name FROM user_constraints WHERE table_name = 'STUDENT'; Here is the result: constraint...

· 如果CONSTRAINTsymbol被给出,它在数据库里必须是唯一的。如果它没有被给出,InnoDB自动创建这个名字。 InnoDB拒绝任何试着在子表创建一个外键值而不匹配在父表中的候选键值的INSERT或UPDATE操作。一个父表有一些匹配的行的子表,InnoDB对任何试图更新或删除该父表中候选键值的UPDATE或DELETE操作有所动作,这个动作...
SQLancer might attempt to insert duplicate values into a column with aUNIQUEconstraint, as completely avoiding such semantic errors is challenging. Third, any bug reported by SQLancer is expected to be a real bug, except those reported by CERT (as performance issues are not as clearly defined as...
There’s just one problem: after there’s been a deadlock, it’s too late. You don’t want to know what held locks in the past, you want to know what holds them now. The deadlock information isn’t usually helpful in finding out what transaction is blocking something from happening....
In this work, a Column-and-Constraint Generation (CCG) algorithm is proposed to tackle this challenge. More precisely, the master problem finds a candidate for Nash equilibrium and the oracle identifies whether this candidate point is indeed an equilibrium. A set of numerical experiments was ...
