sql - powershell读取多行sql

Question

我目前有一个如下所示的 powershell 脚本：

$Query = "SELECT 
         t1.BSM_NM
        ,t1.D_DTM AS MAXDATETIME
        ,t1.TECHNOLOGY
        ,t1.VOICEDATA
        ,CASE
            WHEN t1.VOICEDATA = 'VOICE'
                 AND
                   (
                     t1.CUST_BLK_CNT/t1.ATT_CNT >= t2.MAJOR_VOICE_BLOCK AND t1.CUST_BLK_CNT/t1.ATT_CNT < t2.CRITICAL_VOICE_BLOCK
                     OR
                     t1.DRP_CALL_CNT/t1.ATT_CNT >= t2.MAJOR_VOICE_DROP AND t1.DRP_CALL_CNT/t1.ATT_CNT < t2.CRITICAL_VOICE_DROP
                     OR
                     t1.AXS_F_CNT/t1.ATT_CNT >= t2.MAJOR_VOICE_AXSFAIL AND t1.AXS_F_CNT/t1.ATT_CNT < t2.CRITICAL_VOICE_AXSFAIL
                   )
            THEN 1
            WHEN t1.VOICEDATA = 'DATA'
                 AND
                   (
                     t1.CUST_BLK_CNT/t1.ATT_CNT >= t2.MAJOR_VOICE_BLOCK AND t1.CUST_BLK_CNT/t1.ATT_CNT < t2.CRITICAL_DATA_BLOCK
                     OR
                     t1.DRP_CALL_CNT/t1.ATT_CNT >= t2.MAJOR_VOICE_DROP AND t1.DRP_CALL_CNT/t1.ATT_CNT < t2.CRITICAL_DATA_DROP
                     OR
                     t1.AXS_F_CNT/t1.ATT_CNT >= t2.MAJOR_VOICE_AXSFAIL AND t1.AXS_F_CNT/t1.ATT_CNT < t2.CRITICAL_DATA_AXSFAIL
                   )
            THEN 1
            WHEN t1.VOICEDATA = 'VOICE'
                 AND
                   (
                     t1.CUST_BLK_CNT/t1.ATT_CNT >= t2.CRITICAL_VOICE_BLOCK
                     OR
                     t1.DRP_CALL_CNT/t1.ATT_CNT >= t2.CRITICAL_VOICE_DROP
                     OR
                     t1.AXS_F_CNT/t1.ATT_CNT >= t2.CRITICAL_VOICE_AXSFAIL
                   )
            THEN 2
            WHEN t1.VOICEDATA = 'DATA'
                 AND
                   (
                     t1.CUST_BLK_CNT/t1.ATT_CNT >= t2.CRITICAL_DATA_BLOCK
                     OR
                     t1.DRP_CALL_CNT/t1.ATT_CNT >= t2.CRITICAL_DATA_DROP
                     OR
                     t1.AXS_F_CNT/t1.ATT_CNT >= t2.CRITICAL_DATA_AXSFAIL
                   )
            THEN 2
            ELSE 0
         END MAJORCRITICAL
        FROM DS3R_FH_ALL_TRIGGER_VIEW t1
        INNER JOIN
        ZDMSN.DS3R_1XRTT_TRIGGERS_THRESHOLD t2
        ON
        t1.BSM_NM = t2.BSC_NM
        AND
        t1.TECHNOLOGY = t2.TECHNOLOGY
        WHERE t1.BSM_NM = 'ARL1' and t1.D_DTM = (SELECT MAX(D_DTM) FROM DS3R_FH_1XRTT_BTS_LVL_KPI WHERE BSM_NM = 'ARL1')"      

$data_set = new-object system.data.dataset
$adapter = new-object system.data.oracleclient.oracledataadapter ($Query, $Connection)
[void] $adapter.Fill($data_set)
$table = new-object system.data.datatable
$table = $data_set.Tables[0]
$bsmNM = $data_set.Tables[0].Rows[0].BSM_NM
$maxDT = $data_set.Tables[0].Rows[0].MAXDATETIME
$majorC = $data_set.Tables[0].Rows[0].MAJORCRITICAL
$table | Select MAJORCRITICAL 
  {  
    if ($majorC -match "*2*" -and $majorC -match "*1*")
    if ($majorC -match "*1*" )
    if ($majorC -match "*2*")

结果是这样回来的：

它没有错误，但它似乎没有做我想做的事。如果 MAJORCRITICAL 列中的任何行的值为 1，我希望它执行第二个 if 语句，如果一行中有 1，另一行有 2，我希望它执行第一个 if陈述。代码运行，但 if 语句没有运行......

Answer 1

您只查看示例中的第一行，因为您没有这样做foreach或类似。

此外，您需要使用(alias )$_来引用当前项目foreach%
