public DBasePlatform()

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
