I am using C# and connecting to a SQL 2000 database. I am building a dynamic query. I am adding to my where clause. I am using this in a loop to create this query and am making it a parameterized query. It worked fine here in  my office. What is wrong?  When I sent it to the customer they received this error:

Exception Searching Object :Internal Query Processor Error: The query processor ran out of stack space during query optimization.
