Body
(n+1) select problem which I am not able to resolve. I am joining tables with non-PK column. My schema <blockquote> Records Record_Id (PK) Carrier_Number Audit_Details AuditId(PK) Carrier_Number </blockquote> There is a one-to-many relationship between Records and Audit_Details. My records.hbm.xml <pre><code><set lazy="true" name="auditDetails" sort="unsorted" table="AUDIT_DETAILS" inverse="true"> <key column="Carrier_Number" not-null="true" property-ref="carrierRefNumber"/> <one-to-many class="com.package.AuditDtls" /> </set> </code></pre> My auditDetails.hbm.xml <pre><code><many-to-one class="com.package.Records" fetch="join" name="Records" column="Carrier_Number" not-null="true" property-ref="carrierNumber" lazy="false"/> </code></pre> This produces a query like <pre><code>select this_.CARRIER_NUMBER as CARRIER1_2_2_, abc1_.CARRIER_NUMBER as CARRIER8_3_0_, otm4_.CARRIER_NUMBER as CARRIER1_2_1_, from RECORDS this_ inner join AUDIT_DETAILS abc1_ on this_.CARRIER_NUMBER=abc_.CARRIER_NUMBER left outer join RECORDS otm4_ on abc1_.CARRIER_NUMBER=otmp4_.CARRIER_NUMBER where this_.LOAD_ID=? select auditde0_.CARRIER_NUMBER as CARRIER8_1_ from AUDIT_DTLS auditde0_ where auditde0_.CARRIER_NUMBER=? </code></pre> I have tried changing to fetch="select" , changing lazy="false" and lazy="no-proxy" but nothing has worked so far. I am not sure if this problem is because of joining two tables with nonPK column. Would appreciate any suggestions.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
