Method Detail

buildClassTypes

protected java.util.Hashtable buildClassTypes()

Overrides:

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

buildFieldTypes

protected java.util.Hashtable buildFieldTypes()

Overrides:

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

getTimestampFromServer

public java.sql.Timestamp getTimestampFromServer(org.eclipse.persistence.internal.sessions.AbstractSession session,
                                                 java.lang.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

initializePlatformOperators

protected void initializePlatformOperators()

Initialize any platform-specific operators

Overrides:

initializePlatformOperators 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 java.util.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 java.util.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(java.io.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
