Examples of javax.jdo.Query.declareVariables()

javax.jdo.Query.declareVariables()
Declare the unbound variables to be used in the query. Variables might be used in the filter, and these variables must be declared with their type. The unbound variable declaration is a String containing one or more unbound variable declarations separated with semicolons. It follows the syntax for local variables in the Java language. @param variables the variables separated by semicolons.
