2. The method of claim 1 , further comprising: selecting a second candidate value; evaluating, by the computing device via the component, the parametric pattern query against the database with a second parameter set to the second candidate value, wherein the parametric pattern query further includes the second parameter; adjusting, by the computing device, the second candidate value; and the repeating the evaluating the parametric pattern query against the database with the parameter set to the adjusted candidate value further comprising the second parameter set to the adjusted second candidate value.
3. The method of claim 2 , wherein the parametric pattern query is a SQL query of the form: 
 SELECT * from T WHERE p # T.c OPERATOR p2 # 2 T.c where T represents a table of the database that includes the column, and where p is the parameter, and where # represents an arithmetic expression, and where T.c represents the column, and where OPERATOR represents a logical operator, and where p 2 is the second parameter, and where # 2 represents a second arithmetic expression.
