SybaseDatabase

public SybaseDatabase()

Method Details

getShortName

public String getShortName()

Description copied from interface: Database

Returns an all-lower-case short name of the product. Used for end-user selecting of database type such as the DBMS precondition.

getPriority

public int getPriority()

getDefaultPort

public Integer getDefaultPort()

getDefaultDatabaseProductName

protected String getDefaultDatabaseProductName()

Specified by:

getDefaultDatabaseProductName in class AbstractJdbcDatabase

supportsDDLInTransaction

public boolean supportsDDLInTransaction()

Sybase does not support DDL and meta data in transactions properly, as such we turn off the commit and turn on auto commit.

Specified by:

supportsDDLInTransaction in interface Database

Overrides:

supportsDDLInTransaction in class AbstractJdbcDatabase

Returns:

True if the database supports DDL within a transaction, otherwise false.

getSystemViews

Description copied from interface: Database

Returns whether this database support initially deferrable columns.

supports

public boolean supports(Class<? extends DatabaseObject> object)

Description copied from interface: Database

Whether this database supports the specified object type. It is invoking the deprecated methods to ensure that extensions are not broken, but once those are removed it will return only true

Parameters:

object - the object type to check
