INSTRUCTOR VINAY NOAH More Than One Tables Our example so far involves only one table “ products “. A practical database contains many  related  tables. + Products have suppliers. If each product has one supplier, and each supplier supplies only one product (known as  one-to-one relationship ), we can simply add the supplier’s data (name, address, phone number) into the  products  table. Suppose that each product has one supplier, and a supplier may supply zero or more products (known as  one-to-many  relationship). Putting the supplier’s data into the products  table results in duplication of data. This is because one supplier may supply many products, hence, the same supplier’s data appear in many rows. This not only wastes the storage but also easily leads to inconsistency (as all duplicate data must be updated simultaneously). The situation is even more complicated if one product has many suppliers, and each supplier can supply many products, in a many-to-many  relation

INSTRUCTOR VINAY NOAH Update Query +   + CAUTION : If the  WHERE  clause is omitted in the  UPDATE  command, ALL ROWS will be updated. Hence, it is a good practice to issue a  SELECT  query, using the same criteria, to check the result set before issuing the  UPDATE . This also applies to the  DELETE  statement in the following section. +

INSTRUCTOR VINAY NOAH Select Query + Comparison Operators For numbers ( INT ,  DECIMAL ,  FLOAT ), you could use comparison operators:  '='  (equal to),  '<>'  or  '!='  (not equal to),  '>'  (greater than),  '<'  (less than),  '>='  (greater than or equal to),  '<='  (less than or equal to), to compare two numbers. For example,  price > 1.0 ,  quantity <= 500 . CAUTION: Do not compare  FLOAT s (real numbers) for equality ( '='  or  '<>' ), as they are not precise. On the other hand,  DECIMAL  are precise. For strings, you could also use  '=' ,  '<>' ,  '>' ,  '<' ,  '>=' ,  '<='  to compare two strings (e.g.,  productCode = 'PEC').  The ordering of string depends on the so-called  collation  chosen. For example, + + String Pattern Matching –  LIKE  and  NOT LIKE For strings, in addition to f
