IBM ISERIES SC41-5210-04 - Manual (Page 109)

Records are selected if the data in the field
BALDUE is less than or equal to the data in the field CRLIMIT.
When you test for RANGE, the contents of the field must be within the range of two values (greater than
or equal to the first value but less than or equal to the second) for the record to be selected. On the Select
Records display, you must specify two values in the Value column, and you must separate them by a
blank. If the first value is greater than the second value for a record, that record will not be selected.
For example, you want to select records only for the months of February through August. The field named
MONTH is a numeric field, and it contains a 1 to represent January, a 2 to represent February, a 3 to
represent March, and so on. On the Select Records display, you would specify:
Select Records
Type comparisons, press Enter. Specify OR to start each new group.
Tests: EQ, NE, LE, GE, LT, GT, RANGE, LIST, LIKE, IS, ISNOT...
AND/OR Field Test Value (Field, Number, or ’Characters’)
MONTH_________ RANGE 2 8___________________________
____ ______________ _____ ______________________________
____ ______________ _____ ______________________________
To use the GT, GE, LT, LE, and RANGE tests for SBCS character fields and values, you may need to
know the collating sequence. The collating sequence determines what characters are greater than or less
than others. If you do not select a different one, the hexadecimal collating sequence is used and:
v Most special characters are less than letters.
v Lowercase letters are less than uppercase.
v Letters are less than numbers.
For example, the characters A, 8, &, and b would sort from low to high as follows:
&
b
A
8
For more information about selecting or defining a collating sequence, see Chapter 9, “Selecting a collating
sequence in Query for iSeries”.
Testing for values in a list (LIST NLIST) in Query for iSeries
Use the LIST, NLIST tests to determine if the content of a field is equal or not to one of the values that
you list in the Value column on the Select Records display.
Note: See “CCSID and record selection tests in Query for iSeries” on page 253 for information on
CCSIDs and how they affect the Select Records display.
When you compare a field with a list, the record is selected if the contents of the field exactly match one
of the values you specify. The values you specify in the list:
v Must be numeric constants if you are comparing a numeric field with them.
v Must be SBCS character constants if you are comparing an SBCS character field with them.
v Must be SBCS, DBCS-only, or DBCS-open character constants if you are comparing a bracketed-DBCS
field with them. (If the field being tested is a DBCS-only field, the constant can only be a DBCS-only
constant.)
v Must be DBCS-graphic character constants if you are comparing a DBCS-graphic character field with
them.
v Must be separated by blanks.
v Cannot be field names.
