hello @mlilius , CHARACTER SET grammar should be supported in this feature follows https://dev.mysql.com/doc/refman/5.7/en/cast-functions.html . see examples : "SELECT CAST('test' AS CHAR CHARACTER SET utf8 COLLATE utf8_bin);" |

This will not handle all versions of CAST but will handle a simple case like CAST(pct*100 AS int)
The query mentioned in #9 was used as the test.
select concat(dsw_cluster_name,',',logic_pod_name) as event_obj, concat(dsw_cluster_name,',',logic_pod_name, ' PFC STORM. 详情: ', '流量突跃 ', cast(FLOW_RX_BPS_RATE100 as int), '%(RX)', '; ', cast(FLOW_TX_BPS_RATE100 as int), '%(TX)', '; PFC 突增 ', cast(PFC_RX_PPS_RATE*100 as int), '%(RECV)') as brief from SOURCE_BASIC_EVENT_POD_FLOW_AND_PFC_TREND where win_end >= '2020-05-19 21:14:12' and win_end < '2020-05-20 21:14:12' and PFC_RX_PPS_RATE >= 100 and (FLOW_RX_BPS_RATE <= -0.2 and FLOW_TX_BPS_RATE <= -0.2)
