PowerShell不引用数组元素

Question

我创建了数组example.org。如果我执行$SQL_output循环，则会显示内容

foreach

输出

foreach ($j in $SQL_output){
    write-host $j
}

当我将它添加到SQL语句

时

118543
44021
84992
46888

字符串扩展为

$SQL_UPDATE = "BEGIN
                  IF NOT EXISTS (SELECT 1
                                 FROM dbo.Stats
                                 WHERE Date_of_Download = CAST(GETDATE() AS DATE))
                  BEGIN
                      INSERT INTO dbo.Stats (Date_of_Download, Windows_SEP_11, Mac_SEP_11, Windows_SEP_12, Mac_SEP_12)
                      VALUES (CAST(GETDATE() AS DATE), $SQL_output[0],$SQL_output[1],$SQL_output[2],$SQL_output[3])
                  END
              END
"

如何解决？

Answer 1

用$（SQL_output [x]）

替换$ SQL_output [x]

$SQL_UPDATE = "BEGIN
              IF NOT EXISTS (SELECT 1
                             FROM dbo.Stats
                             WHERE Date_of_Download = CAST(GETDATE() AS DATE))
              BEGIN
                  INSERT INTO dbo.Stats (Date_of_Download, Windows_SEP_11, Mac_SEP_11, Windows_SEP_12, Mac_SEP_12)
                  VALUES (CAST(GETDATE() AS DATE), $($SQL_output[0]),$($SQL_output[1]),$($SQL_output[2]),$($SQL_output[3]))
              END
          END
