title: expdp where clause errors
body: <p>I'm attempting to do an export dump based on a query clause. The table holds 2.37bil rows and i need to dump a subset of those. Here is my parfile</p>
  
  <pre><code>DIRECTORY=EXPSOURCE
  DUMPFILE=obs_fact_%u.dmp
  PARALLEL=4
  TABLES=schema1.observation_fact
  QUERY='schema1.observation_fact:"WHERE concept_cd &lt; ''ICD10CM:N93.0'';"'
  </code></pre>
  
  <p>This is producing the following error</p>
  
  <pre><code>ORA-31693: Table data object "SCHEMA1"."OBSERVATION_FACT" failed to load/unload and is being skipped due to error:
  ORA-00933: SQL command not properly ended
  </code></pre>
  
  <p>I tired wrapping the concept_cd code in quotations rather than double ' but receiving the same error. I've been researching for awhile now with no advancement.</p>
