Linq query using contains is not working
<p>I would like to use a query in LINQ and use a function that works like "LIKE" in TSQL.
For example:</p>

<pre><code> SELECT salary 
 FROM employees 
 WHERE last_name LIKE 'R%';
</code></pre>

<p>I am trying to make a query in LINQ to an Oracle DB. The query seems to work very well when I am not using .Contains() and when I add it I get 0 records back.
I am not sure if Contains() is the correct method to do this. 
Here is my LINQ code:</p>

<pre><code> var queryOracle = (from TS in dbOracle.BI_TYPE_SERVICE
                                join MS in dbOracle.BI_MTR_SRV on TS.BI_ACCT equals MS.BI_ACCT
                                join SL in dbOracle.BI_SRV_LOC on MS.BI_SRV_LOC_NBR equals SL.BI_SRV_LOC_NBR
                                join C in dbOracle.BI_CONSUMER on TS.BI_ACCT equals C.BI_ACCT
                                join P in dbOracle.BI_PERSONAL on C.BI_CUST_NBR equals P.BI_CUST_NBR
                                join STR in dbOracle.BI_SRV_STAT_REF on TS.BI_SRV_STAT_CD equals STR.BI_SRV_STAT_CD
                               where  P.BI_FORMAT_NAME.Contains("Tom")

                              ServiceStatCD = TS.BI_SRV_STAT_CD,
                              ServiceStatus = STR.BI_SRV_STAT_DESC,
