org.hibernate.MappingException: Unable to find column with logical name

Question

hi my tables are as follows:

1- medical_company:

• medical_company_id foreign key on account_entity ta

Answer 1

This error is telling you that there is no column on the medical_company table called medical_company_id. The column on medical_company is just called id.

Answer 2

For those who ran into this problem and are using globally_quoted_identifiers, this helped me:

Change

@JoinColumns({
    @JoinColumn(name = "new_col_1", referencedColumnName = "ref_col_1"),
    @JoinColumn(name = "new_col_2", referencedColumnName = "ref_col_2")
})

To

@JoinColumns({
    @JoinColumn(name = "new_col_1", referencedColumnName = "`ref_col_1`"),
    @JoinColumn(name = "new_col_2", referencedColumnName = "`ref_col_2`")
})

Notice the backtick wrapping the referencedColumnName value.

Answer 3

I would remove the referencedColumnName attribute in MedicalCompany because you are naming the primary key field of AccountEntity. I think it is only necessary if you if it references a non-primary-key field.

@JoinColumn(name = "medical_company_id", referencedColumnName = "account_entity_id")
