public class TableSequence
Purpose: Defines sequencing through using a SEQUENCE table.
Description This is the default sequencing mechanism. A table defaulting to SEQUENCE is used to generate unique ids. The table has a name field (SEQ_NAME) storing each sequences name, and a counter (SEQ_COUNT) storing the last sequence id generated. There will be a row in the table for each sequence object.
Field Summary | |
---|---|
protected java.lang.String |
counterFieldName
Hold the name of the column in the sequence table which specifies the sequence numeric value |
static java.lang.String |
defaultTableName
Deprecated. Use an empty string as a default sequence table name instead, that triggers usage of platform.getDefaultSequenceTableName() when the sequence is connected. |
protected java.lang.String |
nameFieldName
Hold the name of the column in the sequence table which specifies the sequence name |
protected org.eclipse.persistence.internal.helper.DatabaseTable |
table
Hold the database table |
