    Description

      Impala regexp_replace function appears to collide with prepared values only when attemping to replace apostrophe.

      select impala.regexp_replace(string_column,char(39),concat('&apos',char(59)))
      from some_impala_table
      where date_key = concat(substring('2016-01-15',1,7),'-01')
      and customer_id = 112

      Error:

      org.teiid.runtime.client.TeiidClientException: java.lang.RuntimeException: Remote org.teiid.core.TeiidProcessingException: TEIID30504 warehouse: 500051 TEIID11008:TEIID11004 Error executing statement(s): [Prepared Values: ['2016-01-01'] SQL: SELECT regexp_replace(g_0.`string_column`, '\'', ''') FROM some_impala_table g_0 WHERE g_0.`process_date_key` = ?
