VMS Help  —  RDML72  Statements  BETWEEN
    Creates a record stream containing records with values that fall
    within a range you specify.

    The BETWEEN conditional expression is true (records are included
    in the stream) if the first value expression is between the
    second and third value expression, or equal to one of them.
    If you precede the BETWEEN expression with the optional NOT
    qualifier, the condition is true if there are no records within
    the range you specify with the second and third value expression.

    The BETWEEN conditional expression sorts records in ascending
    order by default. For information on sorting records see the
    entry on the SORT statement.

1  –  Examples

    The following programs demonstrate the use of the BETWEEN
    conditional expression with a numeric field. These programs form
    a record stream consisting of all the records in the relation
    CURRENT_SALARY where the field SALARY_AMOUNT contains a value
    greater than or equal to 10,000, and less than or equal to
    20,000. These programs print the last name and salary from of
    each record in the record stream.

1.1  –  C Example

    #include <stdio.h>
    DATABASE PERS = FILENAME "PERSONNEL";

    main()
    {
    READY PERS;
    START_TRANSACTION READ_WRITE;

    FOR CS IN CURRENT_SALARY
       WITH CS.SALARY_AMOUNT
       BETWEEN 10000.00 AND 20000.00
          printf ("%s %f\n", CS.LAST_NAME, CS.SALARY_AMOUNT);
    END_FOR;

    COMMIT;
    FINISH;
    }

1.2  –  Pascal Example

    program between_numeric (input,output);
    DATABASE PERS = FILENAME 'PERSONNEL';

    begin
    READY PERS;
    START_TRANSACTION READ_ONLY;

    FOR CS IN CURRENT_SALARY
       WITH CS.SALARY_AMOUNT
       BETWEEN 10000.00 AND 20000.00
          writeln (CS.LAST_NAME, CS.SALARY_AMOUNT :10:2);
    END_FOR;

    COMMIT;
    FINISH;
    end.

2.1  –  Format arguments

    value-expr             A value expression. A symbol or a string
                           of symbols used to calculate a value. When
                           you use a value expression in a statement,
                           Oracle Rdb calculates the value associated
                           with the expression and uses that value
                           when executing the statement.
