DROP SHADOW ALGORITHM 语法用于从当前逻辑库中删除影子库压测算法。
DropShadowAlgorithm ::=
'DROP' 'SHADOW' 'ALGORITHM' ifExists? algorithmName (',' algorithmName)*
ifExists ::=
'IF' 'EXISTS'
algorithmName ::=
identifier
ifExists 子句用于避免 shadow algorithm not exists 错误。DROP SHADOW ALGORITHM shadow_rule_t_order_sql_hint_0, shadow_rule_t_order_item_sql_hint_0;
DROP SHADOW ALGORITHM shadow_rule_t_order_sql_hint_0;
ifExists 子句删除影子库压测算法DROP SHADOW ALGORITHM IF EXISTS shadow_rule_t_order_sql_hint_0;
DROP、SHADOW、ALGORITHM、IF、EXISTS
