Informix Error Messages and Error Codes From Error 559 to 561
Informix Error Code -559 Cannot create a synonym on top of another synonym.
This CREATE SYNONYM statement names another synonym. Making a chain of synonyms is not supported. See the discussion of error -218 for a way to list the names of all synonyms. To have a second synonym with the same meaning as the first, find out the meaning of the other synonym. Then make a new synonym to refer to the same base table. To see the base table for a given synonym, query systables and syssyntable as follows, substituting the name of the synonym:
SELECT T.tabname synonym, S.* FROM systables T, syssyntable S
WHERE T.tabname = name AND T.tabid = S.tabid
If btabid is defined in the resulting display, the synonym refers to a table in that current database with that tabid; otherwise, it refers to an external database.
Informix Error Code -560 Synonym with tabid number not found in systables.
Either the systables or syssyntable system catalog, or an index on one of these, has been corrupted. Run the bcheck or secheck utility. Be prepared to drop and re-create all synonyms.
Informix Error Code -561 Sums and averages cannot be computed on datetime values.
This statement applies an aggregate function such as SUM to a column that has the type DATETIME. The function is not defined on this data type since arithmetic is not. Review the use of aggregate functions. You will have to revise the query.
