public void setOutputDefaultCatalog(boolean outputDefaultCatalog)

Specified by:

setOutputDefaultCatalog in interface Database

isDefaultSchema

public boolean isDefaultSchema(String catalog,
 String schema)

Description copied from interface: Database

If the database supports schemas, test if a given combination of catalog and schema name equals to the default catalog and schema of the current logged in user.

Specified by:

isDefaultSchema in interface Database

Parameters:

catalog - catalog name to be tested

schema - schema name to be tested

Returns:

if the database supports catalogs: true if it is the default schema, false if not. If it does not support schemas, the behaviour of this method is undefined (please call supportsSchemas first!)

Specified by:

isDefaultCatalog in interface Database

Parameters:

catalog - catalog name to be tested

unescapeDataTypeName

public String unescapeDataTypeName(String dataTypeName)

Specified by:

validate

public ValidationErrors validate()

Specified by:

supportsNotNullConstraintNames

public boolean supportsNotNullConstraintNames()

Description copied from interface: Database

Does this database treat NOT NULL as an own kind of CONSTRAINT (in addition of simply being a column property)? This will affect the CONSTRAINT clause SQL generators.

Specified by:

supportsNotNullConstraintNames in interface Database

Returns:

true if the database supports naming NOT NULL constraints, false if not.

supportsBatchUpdates

public boolean supportsBatchUpdates()

Description copied from interface: Database

Does the database support batched DML (INSERT/UPDATE/DELETE/MERGE/...) statements sent in a single call to the database?

Specified by:

supportsBatchUpdates in interface Database

Returns:

true if the database has this capability for all DML statements, false in all other cases

getMaxFractionalDigitsForTimestamp

public int getMaxFractionalDigitsForTimestamp()

Description copied from interface: Database

Determines the maximum precision (number of fractional digits) for TIMESTAMP columns for the given database. Might not always be able to give an exact answer since, for some DBMS, it depends on the actual software version if fractional digits are supported. A warning should be logged in this case.

Specified by:

getMaxFractionalDigitsForTimestamp in interface Database

Returns:

the number of allowed fractional digits for TIMESTAMP columns. May return 0.

getDefaultFractionalDigitsForTimestamp

public int getDefaultFractionalDigitsForTimestamp()

Description copied from interface: Database

When a TIMESTAMP column without the parameter "number of fractional digits" is created, what is the default value?

Specified by:

getDefaultFractionalDigitsForTimestamp in interface Database

Returns:

The default number of fractional digits for TIMESTAMP columns

requiresExplicitNullForColumns

public boolean requiresExplicitNullForColumns()

Description copied from interface: Database

Does the database require explicit NULL for nullable columns?

Specified by:

requiresExplicitNullForColumns in interface Database

Returns:

true if the database behaves incorrectly if NULL is not explicitly specified, false if it behaves like any good RDBMS should.

supportsCreateIfNotExists

public boolean supportsCreateIfNotExists(Class<? extends DatabaseObject> type)

Description copied from interface: Database

Does the database support the "if not exits" syntax?

Specified by:

supportsCreateIfNotExists in interface Database

Parameters:

type - the DatabaseObject type to be checked.

Returns:

true if the "if not exists" syntax is supported, false otherwise.
