Constructor Detail

HanaExecutionFactory

public HanaExecutionFactory()

Method Detail

start

public void start()
           throws TranslatorException

Description copied from class: ExecutionFactory

Initialize the connector with supplied configuration

Overrides:

start in class JDBCExecutionFactory

Throws:

TranslatorException

getHibernateDialectClassName

public String getHibernateDialectClassName()

Overrides:

getHibernateDialectClassName in class JDBCExecutionFactory

getSupportedFunctions

public List<String> getSupportedFunctions()

Description copied from class: ExecutionFactory

Get list of all supported function names. Arithmetic functions have names like "+".

Overrides:

getSupportedFunctions in class JDBCExecutionFactory

See Also:

for a listing of system pushdown functions. Note that not all system functions are listed as some functions will use a common name such as CONCAT vs. the || operator, and other functions will be rewritten and not pushed down, such as SPACE.
Note: User defined functions should be specified fully qualified.

supportsCompareCriteriaEquals

public boolean supportsCompareCriteriaEquals()

Description copied from class: ExecutionFactory

Support indicates connector accepts criteria of form (element = constant)

Overrides:

supportsCompareCriteriaEquals in class JDBCExecutionFactory

supportsInCriteria

public boolean supportsInCriteria()

Description copied from class: ExecutionFactory

Support indicates connector accepts criteria of form (element IN set)

Overrides:

supportsInCriteria in class JDBCExecutionFactory

translateLimit

public List<?> translateLimit(Limit limit,
                              ExecutionContext context)

Description copied from class: JDBCExecutionFactory

Return a List of translated parts (LanguageObjects and Objects), or null if to rely on the default translation.

Overrides:

translateLimit in class JDBCExecutionFactory

Returns:

a list of translated parts

getMetadata

public void getMetadata(MetadataFactory metadataFactory,
                        Connection connection)
                 throws TranslatorException

Description copied from class: ExecutionFactory

Implement to provide metadata to the metadata for use by the engine. This is the primary method of creating metadata for dynamic VDBs.

Overrides:

getMetadata in class JDBCExecutionFactory

connection - may be null if the source is not required

Throws:

TranslatorException - to indicate a recoverable error, otherwise a RuntimeException

See Also:

ExecutionFactory.isSourceRequiredForMetadata()

getMetadataProcessor

public MetadataProcessor<Connection> getMetadataProcessor()

Description copied from class: ExecutionFactory

Get a MetadataProcessor for the translator to read the metadata. Typically this will return a new instance.

Overrides:

getMetadataProcessor in class JDBCExecutionFactory

Returns:

supportsOnlyLiteralComparison

public boolean supportsOnlyLiteralComparison()

Overrides:

supportsOnlyLiteralComparison in class ExecutionFactory<DataSource,Connection>

Returns:

true if only Literal comparisons (equality, ordered, like, etc.) are supported for non-join conditions.

getSQLConversionVisitor

public SQLConversionVisitor getSQLConversionVisitor()

Description copied from class: JDBCExecutionFactory

Create the SQLConversionVisitor that will perform translation. Typical custom JDBC connectors will not need to create custom conversion visitors, rather implementors should override existing JDBCExecutionFactory methods.

Overrides:

getSQLConversionVisitor in class JDBCExecutionFactory

Returns:

the SQLConversionVisitor

translate

public List<?> translate(LanguageObject obj,
                         ExecutionContext context)

Hana doesn't provide min/max(boolean)

Overrides:

translate in class JDBCExecutionFactory

Returns:

list of translated parts

translateLiteralBoolean

public String translateLiteralBoolean(Boolean booleanValue)

Description copied from class: JDBCExecutionFactory

Subclasses should override this method to provide a different sql translation of the literal boolean value. By default, a boolean literal is represented as: '0' or '1'.

Overrides:

translateLiteralBoolean in class JDBCExecutionFactory

Parameters:

booleanValue - Boolean value, never null

Returns:

Translated string
