Overrides:

supports in class AbstractSqlGenerator<AddUniqueConstraintStatement>

validate

public ValidationErrors validate(AddUniqueConstraintStatement addUniqueConstraintStatement,
                                 Database database,
                                 SqlGeneratorChain<AddUniqueConstraintStatement> sqlGeneratorChain)

Description copied from interface: SqlGenerator

Validate the data contained in the SqlStatement. If there are no errors, return an empty ValidationErrors object, not a null value. Liquibase will inspect the ValidationErrors result before attempting to call generateSql.

generateSql

public Sql[] generateSql(AddUniqueConstraintStatement statement,
                         Database database,
                         SqlGeneratorChain<AddUniqueConstraintStatement> sqlGeneratorChain)

Description copied from interface: SqlGenerator

Generate the actual Sql for the given statement and database.

getAffectedUniqueConstraint

protected UniqueConstraint getAffectedUniqueConstraint(AddUniqueConstraintStatement statement)
