R2-1.6.2 String% — String constant followed by the “%” or “*” wild character. A wildcard character can also be
used by itself to match everything. Use a wildcard character only at the end of the string constant.
R2-1.6.3 nested-propositional-expression — AND|OR propositional-formula [nested-propositional-formula]
NOTE 1: A semicolon is required at the end of SQL statements. The ‘;’ indicates the SQL statement is complete.
NOTE 2: Parentheses can be used in the usual way to group expressions and establish precedence.
NOTE 3: Floating-point comparisons are approximate. Testing for equality with floating point values is not recommended.

NOTICE: This related information is not an official part of SEMI E125 and was derived from the work of the
originating committee. This related information was approved for publication by full letter ballot procedures.
R3-1 Examples
R3-1.1 This clause specifies that all values of “voltage” that are less than or equal to 50 are valid (i.e., it evaluates
true for all values of voltage less than or equal to 50).
WHERE voltage <= 50;
R3-1.2 The following clauses specifies that all values of “voltage” that are between 0 and 50 (inclusive) are valid.
WHERE voltage >= 0 AND voltage <= 50;
R3-1.3 The clause specifies that all values of “voltage” that are 50 and less or 100 and greater (inclusive) are valid.
WHERE voltage <= 50 OR voltage >= 100;
R3-1.4 The following clause specifies that only “voltage” values of 1, 2, 4, 8 and 16 are valid.
WHERE voltage = 1 OR voltage = 2 OR voltage = 4 OR voltage = 8 OR voltage = 16;
R3-1.5 The following clause specifies that any “voltage” value that is not 1, 2, 4, 8 or 16 is valid.
WHERE voltage <> 1 AND voltage <> 2 AND voltage <> 4 AND voltage <> 8 AND voltage <> 16;

PARAMETER REPORTING PERIOD CONSTRAINTS
NOTICE: This related information is not an official part of SEMI E125 and was derived from the work of the
originating committee. This related information was approved for publication by full letter ballot procedures.
R4-1 Examples
R4-1.1 The constraint definition below specifies that the supported reporting period for “voltage” is any continuous
value between 0.01 seconds and 60 seconds.
WHERE voltage.ReportingPeriod > .01 AND voltage.ReportingPeriod < 60;
R4-1.2 The constraint definition below specifies that the supported reporting period for “voltage” is any integer
multiple (from 1 to 6000) of a fundamental period of 0.01 seconds.
WHERE voltage.ReportingPeriod = ( n*.01) AND n > 1 AND n < 6000;
R4-1.3 The constraint definition below specifies that the supported reporting period for “voltage” is any of the
discrete values 0.05 seconds, 0.07 seconds, 0.1 seconds, or 1.5 seconds.
WHERE voltage.ReportingPeriod = .05 OR voltage.ReportingPeriod =.07 OR voltage.ReportingPeriod =
.1 OR voltage.ReportingPeriod = 1.5
