The attempt was made to specify a parameter in a <SELECT COLUMN>.
A COMPARISON PREDICATE of the format <PARAMETER SPEC> <COMP OP> <PARAMETER SPEC> occurs within the SEARCH CONDITION.
A COMPARISON PREDICATE, IN PREDICATE or QUANTIFIED PREDICATE specifies a comparison between a parameter and a SUBQUERY.
User Action:
Replace the parameter with a constant.
It is useful to check such a condition within the application. If this is not possible, replace one of the two parameters with a constant, a column name, or an <EXPRESSION> which does not solely contain parameters.
Replace the parameter with a constant or integrate it into a function (e.g. SUBSTR) so that the data type of the parameter becomes clear.
