Method Summary

java.sql.Timestamp	getTimestampFromServer(oracle.toplink.publicinterface.Session session, java.lang.String sessionName) Access do not support millisecond well, truncate the millisecond from the timestamp
boolean	isAccess()
java.util.Hashtable	maximumNumericValues() Builds a table of maximum numeric values keyed on java class.
java.util.Hashtable	minimumNumericValues() Builds a table of minimum numeric values keyed on java class.
void	printFieldNotNullClause(java.io.Writer writer) Append the receiver's field 'NOT NULL' constraint clause to a writer.
boolean	requiresNamedPrimaryKeyConstraints() This is used as some databases create the primary key constraint differently, i.e.
boolean	shouldUseJDBCOuterJoinSyntax() JDBC defines and outer join syntax, many drivers do not support this.

Method Detail

getTimestampFromServer

public java.sql.Timestamp getTimestampFromServer(oracle.toplink.publicinterface.Session session,
                                                 java.lang.String sessionName)

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

Overrides:

getTimestampFromServer in class DatabasePlatform

isAccess

public boolean isAccess()

Overrides:

isAccess in class DatabasePlatform

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 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 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 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
