Method Detail

buildFieldTypes

protected java.util.Hashtable buildFieldTypes()

Overrides:

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

convertToDatabaseType

public java.lang.Object convertToDatabaseType(java.lang.Object value)

INTERNAL We support more primitive than JDBC does so we must do conversion before printing or binding.

Overrides:

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

setParameterValueInDatabaseCall

public void setParameterValueInDatabaseCall(java.lang.Object parameter,
                                            java.sql.PreparedStatement statement,
                                            int index,
                                            org.eclipse.persistence.internal.sessions.AbstractSession session)
                                     throws java.sql.SQLException

INTERNAL: DBase does not support Time/Timestamp so we must map to strings.

Overrides:

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

Throws:

java.sql.SQLException

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

getSelectForUpdateString

public java.lang.String getSelectForUpdateString()

Overrides:

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

isDBase

public boolean isDBase()

Specified by:

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

Overrides:

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

maximumNumericValues

public java.util.Hashtable maximumNumericValues()

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:

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

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

supportsForeignKeyConstraints

public boolean supportsForeignKeyConstraints()

Overrides:

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

supportsPrimaryKeyConstraint

public boolean supportsPrimaryKeyConstraint()

Overrides:

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