Constructor Detail

AccessPlatform

public AccessPlatform()

Method Detail

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 org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

getTimestampFromServer

public Timestamp getTimestampFromServer(org.eclipse.persistence.internal.sessions.AbstractSession session,
                               String sessionName)

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

Specified by:

getTimestampFromServer in interface org.eclipse.persistence.internal.databaseaccess.Platform

Overrides:

getTimestampFromServer in class org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform

isAccess

public boolean isAccess()

Specified by:

isAccess in interface org.eclipse.persistence.internal.databaseaccess.Platform

Overrides:

isAccess in class org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform

maximumNumericValues

public Hashtable 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 org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

minimumNumericValues

public Hashtable 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 org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

printFieldNotNullClause

public void printFieldNotNullClause(Writer writer)

Append the receiver's field 'NOT NULL' constraint clause to a writer.

Overrides:

printFieldNotNullClause in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

requiresNamedPrimaryKeyConstraints

public boolean requiresNamedPrimaryKeyConstraints()

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

Overrides:

requiresNamedPrimaryKeyConstraints in class org.eclipse.persistence.internal.databaseaccess.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 org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

buildSelectQueryForIdentity

public ValueReadQuery buildSelectQueryForIdentity()

INTERNAL: Build the identity query for native sequencing.

Overrides:

buildSelectQueryForIdentity in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

printFieldIdentityClause

public void printFieldIdentityClause(Writer writer)
                              throws ValidationException

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

Overrides:

printFieldIdentityClause in class org.eclipse.persistence.internal.databaseaccess.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 org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

printFieldTypeSize

public void printFieldTypeSize(Writer writer,
                      FieldDefinition field,
                      org.eclipse.persistence.internal.databaseaccess.FieldTypeDefinition fieldType,
                      boolean shouldPrintFieldIdentityClause)
                        throws IOException

Overrides:

printFieldTypeSize in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

Throws:

IOException

printFieldUnique

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

Overrides:

printFieldUnique in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

Throws:

IOException
