Constructor Details

AccessPlatform

public AccessPlatform()

Default constructor.

Method Details

buildClassTypes

protected Map<String,Class<?>> buildClassTypes()

Description copied from class: DatabasePlatform

Return the mapping of class types to database types for the schema framework.

Overrides:

buildClassTypes in class DatabasePlatform

buildFieldTypes

protected Hashtable<Class<?>,FieldTypeDefinition> buildFieldTypes()

Description copied from class: DatabasePlatform

Return the mapping of class types to database types for the schema framework.

Overrides:

buildFieldTypes in class DatabasePlatform

getMaxFieldNameSize

public int getMaxFieldNameSize()

INTERNAL: returns the maximum number of characters that can be used in a field name on this platform.

Overrides:

getMaxFieldNameSize in class DatabasePlatform

getTimestampFromServer

public Timestamp getTimestampFromServer(AbstractSession session,
 String sessionName)

Access do not support millisecond well, truncate the millisecond from the timestamp

Specified by:

getTimestampFromServer in interface Platform

Overrides:

getTimestampFromServer in class DatasourcePlatform

initializePlatformOperators

protected void initializePlatformOperators()

Initialize any platform-specific operators

Overrides:

initializePlatformOperators in class DatasourcePlatform

isAccess

public boolean isAccess()

Specified by:

isAccess in interface Platform

Overrides:

isAccess in class DatasourcePlatform

maximumNumericValues

public Hashtable<Class<? extends Number>,? super Number> maximumNumericValues()

Builds a table of maximum numeric values keyed on java class. This is used for type testing but might also be useful to end users attempting to sanitize values.

NOTE: BigInteger & BigDecimal maximums are dependent upon their precision & Scale

Overrides:

maximumNumericValues in class DatabasePlatform

minimumNumericValues

public Hashtable<Class<? extends Number>,? super Number> minimumNumericValues()

Builds a table of minimum numeric values keyed on java class. This is used for type testing but might also be useful to end users attempting to sanitize values.

NOTE: BigInteger & BigDecimal minimums are dependent upon their precision & Scale

Overrides:

minimumNumericValues in class DatabasePlatform

requiresNamedPrimaryKeyConstraints

public boolean requiresNamedPrimaryKeyConstraints()

This is used as some databases create the primary key constraint differently, i.e. Access.

Overrides:

requiresNamedPrimaryKeyConstraints in class DatabasePlatform

shouldUseJDBCOuterJoinSyntax

public boolean shouldUseJDBCOuterJoinSyntax()

JDBC defines and outer join syntax, many drivers do not support this. So we normally avoid it.

Overrides:

shouldUseJDBCOuterJoinSyntax in class DatabasePlatform

buildSelectQueryForIdentity

public ValueReadQuery buildSelectQueryForIdentity()

INTERNAL: Build the identity query for native sequencing.

Overrides:

buildSelectQueryForIdentity in class DatasourcePlatform

printFieldIdentityClause

public void printFieldIdentityClause(Writer writer)
                              throws ValidationException

Append the receiver's field 'identity' constraint clause to a writer.

Overrides:

printFieldIdentityClause in class DatabasePlatform

Throws:

ValidationException

supportsIdentity

public boolean supportsIdentity()

INTERNAL: Indicates whether the platform supports identity. Sybase does through IDENTITY field types. This method is to be used *ONLY* by sequencing classes

Overrides:

supportsIdentity in class DatasourcePlatform

printFieldTypeSize

public void printFieldTypeSize(Writer writer,
 FieldDefinition field,
 FieldTypeDefinition fieldType,
 boolean shouldPrintFieldIdentityClause)
                        throws IOException

Overrides:

printFieldTypeSize in class DatabasePlatform

Throws:

IOException

printFieldUnique

public void printFieldUnique(Writer writer,
 boolean shouldPrintFieldIdentityClause)
                      throws IOException

Overrides:

printFieldUnique in class DatabasePlatform

Throws:

IOException
