如何为sql cmd导出嵌入if语句

Question

我有一个运行并导出 CSV 文件的 SQL cmd。如何与查询中返回的字段进行比较并根据这些字段在导出中显示文本？在它有“标题”部分的地方，我想比较 2 个字段“First_Unit”和“Unit”。如果它们相等，我想添加文本“Primary”，如果它们不相等，那么我想要“Backup”。所以它在本节中，逻辑上看起来是这样的：'BWC - ' + UPPER(Complaint) + 'Primary' ELSE 'Backup' 作为标题。因此，我希望在该列中该数据的末尾出现 2 个文本。

谢谢 TJ

这是原始查询：

sqlcmd -S PDCAD -d Ver2_CAD -E -Q "select Active_Calls.Call_Number AS 'Event ID',Officer_IDs AS 'Officer Badge ID', Date_Received AS 'Officer Dispatched DateTime',Time_Complete AS 'Officer Cleared DateTime',Active_Calls.Call_Number AS 'Report Number',UPPER(Complaint) AS 'Category', '' as Tag,'BWC - ' + UPPER(Complaint) as Title,Actual_Incid_Location AS 'Street',Actual_Incid_City AS 'City', ISNULL(Actual_Incid_State,'CT') AS 'State', RIGHT('0'+CONVERT(VARCHAR,Actual_Incid_ZIP),5) AS 'ZIP Code' from Active_Calls INNER JOIN CALLUNITDATA CALLUNITDATA ON Active_Calls.Call_Number=CALLUNITDATA.Call_Number WHERE Officer_IDs <> 'NHFD' AND Officer_IDs <> 'POST53' AND Officer_IDs <> 'POST54' AND Officer_IDs <> 'POST52'  AND Officer_IDs <> 'DFD' AND Officer_IDs <> 'NFD' AND Officer_IDs <> 'DFD3' AND Officer_IDs <> 'NHFD2' AND Officer_IDs <> 'UNIT50' AND Officer_IDs <> 'NFD2' AND Officer_IDs <> 'DFD2' AND Officer_IDs <> '1129'AND Officer_IDs <> '2120' AND Officer_IDs <> '0341' AND Officer_IDs <> 'MOB.UNIT51' AND Officer_IDs <> '3540' AND Date_Received >= DATEADD(day, -4, GETDATE()) ORDER BY Date_Received" -o "C:\TaserExportFolder\MyData.csv" -h 852544 -s"," -w 700 -W

您可以像这样使用 CASE 语句：

'BWC - ' + UPPER(Complaint) + (CASE WHEN First_Unit = Unit THEN 'Primary' ELSE 'Secondary' END) As Title
