fr.insalyon.citi.golo.compiler.ir.AssignmentStatement
org.teiid.query.sql.proc.AssignmentStatement

This class represents an assignment statement in the storedprocedure language. It extends the Statement that could part of a Block. This statement holds references to the variable and it's value which could be an Expression or a Command.

      List<GoloCompilationException.Problem> problems = expected.getProblems();
