The SQL From clause is the source of a rowset to be operated upon in a Data Manipulation Language (DML) statement.

FROM is an SQL reserved word in the SQL standard. The FROM clause is used in conjunction with SQL statements, and takes the following general form: SQL-DML-Statement FROM table_name WHERE predicate
