Powershell参数验证问题

Question

我正在从另一个脚本中调用这样的Powershell脚本。

function test_execute_sql_2_direct_query()
  {
    & C:\Server\Scripts\PowerShellDeploy\Execute-SQL-Command.ps1 -SERVER_NAME "myserver" -SQL_COMMAND_TYPE "input" -SQL_FILE ".\select.sql" -USER_NAME "username" -PASSWORD "password" -DATABASE "accounts"
  }

当我调用该函数时，我从Powershell收到一条错误消息，提示“无法验证参数'Query'上的参数。 参数为null或为空。...'

我不太明白为什么要收到该消息？ Execute-SQL-Command脚本没有名为“ Query”的参数。 我很可能会丢失一些东西。

这是它的paramenter部分：

param(
[Parameter(
         HelpMessage="Server Name")]
[string]$SERVER_NAME = "",

[Parameter(
         HelpMessage="Database")]
[string]$DATABASE = "",

    [Parameter(
         HelpMessage="Path to .SQL File to run. Used in input file mode (not direct query mode)")]
[string]$SQL_FILE ="",  

    [Parameter(
         HelpMessage="Server Port (default = 1433)")]
[string]$SERVER_PORT = "1433",

    [Parameter(
         HelpMessage="Server Transport (default = tcp")]
[string]$TRANSPORT = "tcp", 

[Parameter(
         HelpMessage="Method of connecting to database <passthrough, credentialed>")]
[string]$CONNECT_METHOD = "passthrough",

[Parameter(
        HelpMessage="Username -- used only for credentialed login")]
[string]$USER_NAME = "username",

[Parameter(
        HelpMessage="Command type-- direct query or input file (.sql)")]
[string]$SQL_COMMAND_TYPE = "DIRECT_QUERY",

[Parameter(
        HelpMessage="SQL statement text type-- used in direct queries")]
[string]$SQL_STATEMENT = "",

[Parameter(
        HelpMessage="Password -- used only for credentialed login")]
[string]$PASSWORD = "pwd")

这是由于用户错误而引起的-实际错误来自Execute-SQL-Command.ps1中的一行-特别是Invoke-Sqlcmd cmdlet。
