Problembeschreibung: | |
When you attempt to offload a query to the Informix Warehouse Accelerator including an expression like cast(max(x0.time_value) as date) < TODAY - 2 you will receive an error 26402 for the offload attempt. Depending on the setting of use_dwa a fallback to the Informix server will be attempted or the query execution will be aborted. There will be an assertion shown in the messages file of the server running the Informix Warehouse Accelerator which will include this information: A query parsing error with description 'An assertion 'false' failed. Additional info: Cast not possible at TEMPORAL_SUBTRACT: {TEMPORAL_SUBTRACT:T0: {CAST:T10: 819:10:02/26/2015:T2(10,819): } SINT16:2:T7: } ' | |

When you specify UNITS for 2 in this example then you can prevent this offload failure. So with cast(max(x0.time_value) as date) < TODAY - 2 UNITS DAY the query should again be successfully offloaded. | |
