方法详细资料

supportsIfExistsBeforeConstraintName

public boolean supportsIfExistsBeforeConstraintName()

从类复制的说明: Dialect

For dropping a constraint with an "alter table", can the phrase "if exists" be applied before the constraint name?

NOTE : Only one or the other (or neither) of this and Dialect.supportsIfExistsAfterConstraintName() should return true

覆盖:

supportsIfExistsBeforeConstraintName 在类中 Dialect

返回:

true if the "if exists" can be applied before the constraint name
