Answer 1

You will see this error if the search condition was entered with an invalid or missing relational operator.
You need to include a valid relational operator such as
  =, !=, ^=, <>, >, <, >=, <=, ALL, ANY, [NOT] BETWEEN, EXISTS, [NOT] IN, IS [NOT] NULL, or [NOT] LIKE in the condition. in the sql statement.
Can you throw some more light on how are you designing your project?
