Method Detail

supportsIfExistsBeforeConstraintName

public boolean supportsIfExistsBeforeConstraintName()

Description copied from class: 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

Overrides:

supportsIfExistsBeforeConstraintName in class Dialect

Returns:

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