Informix will throw an exception when a unique index is explictily created on
the primary key columns
-----------------------------------------------------------------------------------------------------
Key: OPENJPA-605
URL: https://issues.apache.org/jira/browse/OPENJPA-605
Project: OpenJPA
Issue Type: Bug
Reporter: Fay Wang
When an entity is defined as following (unique index annotation on the primary
key field. In this situation):
@Entity
@Table(name="AddressBean")
public class AddressBeanAno implements IAddressBean, Serializable {
@EmbeddedId
@Index(name="street_index",unique=true)
@Column(length=30)
private AddressPK street;
Informix will issue an error:
Caused by: org.apache.openjpa.lib.jdbc.ReportingSQLException: Index already
exists on column. {stmnt 1440372186 CREATE UNIQUE INDEX street_index ON
AddressBean (street)} [code=-350, state=S0011]

Per Informaix SQL syntax guide (Create Index section):
You can not add a unique index to a column or column list that a primary -key
constraint on it. The reason is that defining the column or column list as the
primary key causes the database server to create a unique internal index on the
column or column list. So you cannot create another unique index on this column
or column list with CREATE INDEX statement.
