I am reading a table in Oracle:<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Select &nbsp; t1.CLAIM_NO<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; , t1.KICKOUT_CODE<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;, t1.cert_no<br />
&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; , t1.cost_center<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;, t1.arrv_date<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; From Table1;<br />
<br />
I would like to select only those records where there is only one row where t1.claim_no, t1.cert_no are the same.<br />
<br />
Does anyone know how/if this can be coded as a single query?

Experts,

I am reading a table in Oracle:
	Select   t1.CLAIM_NO
                              , t1.KICKOUT_CODE
	            , t1.cert_no
 	            , t1.cost_center
	            , t1.arrv_date
	 From Table1;

I would like to select only those records where there is only one row where t1.claim_no, t1.cert_no are the same.

Does anyone know how/if this can be coded as a single query?

Selecting only those records where there is only one row - Oraclw query

Oracle is an object-relational database management system. It supports a large number of languages and application development frameworks. Its primary languages are SQL, PL/SQL and Java, but it also includes support for C and C++. Oracle also has its own enterprise modules and application server software.

Oracle Database

SQL (Structured Query Language) is designed to be used in conjunction with relational database products as of a means of working with sets of data. SQL consists of data definition, data manipulation, and procedural elements. Its scope includes data insert, query, update and delete, schema creation and modification, and data access control.
