Hi,
I'm having an issue when trying to insert an object using JPA(provider: eclipselink, version: 2.5.0), jTds driver version 1.2.8 for database sql server 2012. I used SEQUENCE as generation strategy for the ID generation. Even though the sequence is created in the database the transaction is failed due to the following error:
java.sql.SQLException: Cannot insert the value NULL into column 'ID', table 'Test.dbo.TestTable'; column does not allow nulls. INSERT fails.
here is my JPA Object:
import java.io.Serializable;
import javax.persistence.AttributeOverride;
import javax.persistence.AttributeOverrides;
import javax.persistence.Column;
import javax.persistence.Embedded;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;
@Entity
@Table(name = "TestTable")
public class JPAObject implements Serializable {
private static final long serialVersionUID = 1L;
public JPAObject() {
super();
}
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "IDSQE")
@SequenceGenerator(name = "IDSQE", sequenceName = "IDSQE", allocationSize = 1)
private Integer id;
@Column(name = "DESCRIPTION")
private String description;
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
}
log:
