https://asterix-gerrit.ics.uci.edu/c/asterixdb/+/20644/comment/9f87439b_d33babe4?usp=email
 :
PS6, Line 435:         return expr.accept(new 
AbstractSqlppSimpleExpressionVisitor() {
> I added this for detecting and changing statements like SET u.totaltax= u. […]
Then create a variable above in the class and assign the object to it:
private final AbstractSqlppSimpleExpressionVisitor substitueVisitor = new 
AbstractSqlppSimpleExpressionVisitor () {
String originalVarName = null;
VariableExpr newVar = null;

@Override
            public Expression visit(VariableExpr varExpr, ILangExpression arg) 
throws CompilationException {
                return substituteVariableInExpression(varExpr, originalVarName, 
newVar);
....
}

and here do:
substitueVisitor.originalVarName = originalVarName;
substitueVisitor. newVar = newVar;
return expr.accept(substitueVisitor, null); // shouldn't we pass something 
instead of null?
