Informix Error Messages and Error Codes From Error 8102 to 8105
Informix Error Code -8102 There may be only one AFTER or BEFORE GROUP OF clause for any single column specified in the ORDER BY command.
The report contains more than one AFTER GROUP OF clause for a certain column or more than one BEFORE GROUP OF clause. Only one of each can name a given column. However, you can combine the statements from the multiple clauses into a single clause.
Informix Error Code -8103 In order for the BEFORE or AFTER GROUP OF clause to function properly, the column specified in the clause must also have been specified as a sort column in the ORDER BY command. If the sort column is subscripted, the column in the BEFORE or AFTER GROUP OF clause must be also.
Make sure that the control columns are specified identically in both the ORDER BY statement and the GROUP OF clauses.
Informix Error Code -8104 Group aggregates can only be used in an AFTER GROUP OF clause.
Aggregate values over a group are accumulated while the rows of the group are being processed, so they are not available until the end of the group is seen. Therefore, the report cannot refer to them except in an AFTER GROUP OF clause.
Informix Error Code -8105 Aggregates may not be used within another aggregate. Nor may aggregates be used within the WHERE clause of another aggregate.
Aggregate functions cannot be nested, primarily because the value of the inner aggregate is not known while the outer aggregate is being accumulated. Rewrite aggregate expressions to refer only to columns and simple expressions on columns. In an AFTER GROUP OF clause, you can save the aggregate value from one group of rows in a variable in order to use it to compute an aggregate over a subsequent group.
