当 SQL 中的语句连接多个表时，我有以下情况。 我如何将其转换为 power bi DAX

Question

case when A.status = 'ACTIVATED' and m.caller is not null then 'ACTIVE' when A.status = 'ACTIVATED' and m.caller is null and n.callingparty is not null then 'AINACTIVE' when A.status = 'ACTIVATED' and m.caller is null and n.caller is null then 'NO_USAGE'

Answer 1

Join itself should be resolved by correct relationship in your model inside powerbi.

then write your measure as:

MyMeasureName =
SWITCH (
    TRUE (),
    A[Status] = "ACTIVATED"
        && NOT ( ISBLANK ( M[Caller] ) ), "ACTIVE",
    A[Status] = "ACTIVATED"
        && ISBLANK ( M[Caller] )
        && NOT ( ISBLANK ( N[Callingparty] ) ), "AINACTIVE",
    A[Status] = "ACTIVATED"
        && ISBLANK ( M[Caller] )
        && ISBLANK ( N[Callingparty] ), "NO_USAGE",
    "Label for ELSE"
)
