Syntax
DQMATCHPARSED (parsed-char, 'match-definition' <,sensitivity> <,'locale'> )
Required Arguments
- parsed-char
-
specifies a character
constant, variable, or expression that contains the value that is
the name of the parsed-definition that is associated with the match
definition.
To determine the name
of the associated parse definition, use the DQMATCHINFOGET function.
To determine the tokens that are enabled by that parse definition,
use the DQPARSEINFOGET function.
- match-definition
-
specifies the name
of the match definition. The definition must exist in the locale that
is used.
Optional Arguments
- sensitivity
-
specifies an integer
value that determines the amount of information in the returned match
code. Valid values range from 50 to 95. The default value is 85. A
higher sensitivity value inserts more information in the match code.
In general, higher sensitivity values result in a greater number of
clusters, with fewer members per cluster. Input values must be more
similar to receive the same match codes.
- locale
-
specifies a character
constant, variable, or expression that contains the locale name.
Default:The default locale is the first locale in the locale
list. If no value is specified, the default locale is used.
Example: DQMATCHPARSED Function
The following example
returns a match code for the parsed name of an individual. The amount
of information in the match code is high.
data _null_;
length nameIndividual matchCode $ 20 parsedName $ 200;
nameIndividual='Susan B. Anthony';
parsedName=dqParse(nameIndividual, 'name', 'enusa');
matchCode=dqMatchParsed(parsedName, 'name', 90, 'enusa');
run;
