我目前正在尝试通过OPAM安装CREATE TABLE V_Test AS
SELECT * FROM (select Label, Average from Test)
PIVOT (
SUM(Average) AS sum_average FOR (Label) IN (
'S03_CreatePlansdadsada' as CreatePlans,
'S03_CreatePlan_T01_NavigateTosdsadsaded' as T01_NavigateTo,
'S03_CreatePlan_T03_abcdefgmanagementsdasda' as T03_Managements,
'S03_CreatePlan_T16_SetStatusToOngoingasdasda' as T16_SetStatusToOng,
'S03_CreatePlan_T17_Ldsdssdadsadas' as T17_Lsd
)
) p;
