This error message is worth talking about for two reasons: First, "Driver does not support this parameter" is hopelessly vague (actually misleading), and second, it represents a behavior change in either SQL Anywhere 12 or Windows 7 ODBC. In this specific case, it is no longer possible to use the UNSIGNED BIGINT data type for a SELECT column when the target database is SQL Anywhere 5, presumably because SQL Anywhere 5 does not support BIGINT. Previously, it didn't matter... if the SQL Anywhere 5 column was INTEGER, it was perfectly OK to define the SELECT column as UNSIGNED BIGINT. Somewhere along the way, the rules have been tightened up. It is STILL OK to define the proxy table column as UNSIGNED BIGINT, but you have to CAST it in the SELECT: SELECT CAST ( proxy_SYSTABLE.count AS INTEGER ) FROM proxy_SYSTABLE; In fact, the proxy table column data type is not involved at all; the following SELECT raises the same error even though it doesn't select any proxy table column at all: SELECT CAST ( NULL AS UNSIGNED BIGINT ) AS ccc FROM proxy_ttt; Again, the workaround is to change the data type in the SELECT: SELECT CAST ( proxy_SYSTABLE.count AS INTEGER ) FROM proxy_SYSTABLE; The bottom line: If you see "Driver does not support this parameter" have a look at your data types. |
