    <p>HQL query against a PostgreSQL database:</p> <pre><code>var checkLines = _Session.CreateQuery( @"select lines from FinancialStatement statement inner join fetch statement.FinancialStatementLines lines where statement.FinancialStatementId = :statementId and lines.TransactionType = :transactionType and length(lines.CheckNumber) &gt; 0") .SetParameter("statementId", statement.FinancialStatementId) .SetParameter("transactionType", TransactionTypes.Debit) .List&lt;FinancialStatementLine&gt;(); </code></pre> <p>The query looks OK to me, but I am a newbie at HQL. Can someone tell me what I'm doing wrong? I'm assuming the problem is with the HQL, please let me know if you think I need to look elsewhere.</p> <p><strong>THE PLOT THICKENS</strong></p> <p>Upon examining the query created by the above HQL, I discover it looks like this:</p> <pre><code>select financials1_.LineId as LineId14_, financials1_.FinancialStatementId as Financia2_14_, financials1_.APPaymentID as APPaymen3_14_, financials1_.EffectiveDate as Effectiv4_14_, financials1_.Amount as Amount14_, financials1_.TransactionType as Transact6_14_, financials1_.CheckNumber as CheckNum7_14_, financials1_.Description as Descript8_14_, financials1_.VendorDescription as VendorDe9_14_, financials1_.FinancialStatementId as Financia2_, financials1_.LineId as LineId from FinancialStatements financials0_ where financials0_.FinancialStatementId=:p0 and financials1_.TransactionType=:p1 and length(financials1_.CheckNumber)&gt;0 </code></pre> <p>...now, WTF? The <code>select</code> clause aliases don't exist in the <code>from</code> clause, which explains the error, but not, of course, why the error exists.</p> <p>How can I work around this?</p>

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.
