Examples: SELECT Statements - Teradata Database - Teradata Vantage NewSQL Engine

The following SELECT statements are syntactically correct in Teradata SQL. The first statement does not reference any tables, so a FROM clause is unnecessary. This syntax is a Teradata extension to the ANSI SQL:2011 standard.

     SELECT DATE, TIME;

     SELECT x1,x2
     FROM t1,t2
     WHERE t1.x1=t2.x2;

     SELECT x1
     FROM t1
     WHERE x1 IN (SELECT x2
                  FROM t2);
