    copied!<p>I have a WebGet that is passed one or more provider codes. For each provider code, I need to return a patient list for all inpatients where their code exists as admitting,attending or consulting provider.</p> <p>Should be:</p> <pre><code>WHERE (inpatient = 1) AND (dischargeddate IS NULL) AND ((attending = 'SMITH') OR (admitting = 'SMITH') OR (consulting = 'SMITH')) </code></pre> <p>The "for" loop is not appending the criteria to the where clause. What am I doing wrong?? </p> <p>Thanks</p> <pre><code> [WebGet] public IQueryable&lt;vw_patient&gt; GetInpatients(string providercode, string searchtext) { string[] providers = providercode.Split(new char[] { '|' }); if (string.IsNullOrEmpty(searchtext)) { var results = (from p in this.CurrentDataSource.vw_patient where p.inpatient.Equals(true) &amp;&amp; p.dischargedate.Equals(null) select p); foreach (string provider in providers) { results = results.Where&lt;vw_patient&gt;(e =&gt; e.attending.Equals(provider) || e.admitting.Equals(provider) || e.consulting.Contains(provider)); } results.OrderBy(p =&gt; p.roomloc).ThenByDescending(p =&gt; p.patientname); return results; } else { var results = (from p in this.CurrentDataSource.vw_patient where p.patientname.StartsWith(searchtext) &amp;&amp; p.inpatient.Equals(true) &amp;&amp; p.dischargedate.Equals(null) select p); foreach (string provider in providers) { results = results.Where&lt;vw_patient&gt;(e =&gt; e.attending.Equals(provider) || e.admitting.Equals(provider) || e.consulting.Contains(provider)); } results.OrderBy(p =&gt; p.roomloc).ThenByDescending(p =&gt; p.patientname); return results; } } </code></pre>
