Language Reference
AND Operator
Returns a TRUE value if each logical expression is TRUE.
SYNTAX
expression
An expression that evaluates to a logical value (TRUE or FALSE).
EXAMPLEThis procedure lists all customers with credit limits between two values (supplied by the user and stored in the variables low-credit and hi-credit). The expressions credit-limit >= low-credit and credit-limit <= hi-credit are logical expressions because each yields a true or false value. Using the AND operator to join these logical expressions results in a logical expression that follows the WHERE keyword.
