【问题描述】：

我正在尝试将一个变量从我的 Powershell 脚本传递到 SQLPlus。

我已将变量定义为 $csvStorage（文件夹“csv_files”的文件路径）：

Powershell 脚本：

# Set file path to C:\xxxx\xxxx\xxxx\xxxx\csv_files
$filePath = Split-Path -Path $directory -Parent
$csvStorage = Join-Path $filePath -ChildPath "csv_files"

然后我将它作为参数传递给 SQL 脚本：

Powershell 脚本：

# Run sql_queries.sql whilst passing C:\xxxx\xxxx\xxxx\xxxx\csv_files\ into the SQL script
$queryTables = "/c sqlplus $dbUsername/$dbPassword@$dbServiceName @$filePath $csvStorage"
&$sqlPlus $queryTables

最后，在我的 SQL 中使用 '&1' 引用了该变量：

SQL 脚本：

set null null
set heading on
set pagesize 50000
set termout on

spool &1\hc_actual_vs_shadow_inv.csv

SELECT *
FROM hc_actual_vs_shadow_inv
/
spool off
/
exit

但是，查询没有被执行，也没有输出 .csv 文件。但我看不出我做错了什么。任何帮助将不胜感激。

谢谢

【问题讨论】：

$sqlPlus的内容是什么？

@Tomalak $sqlPlus = "cmd.exe"

此脚本执行指定目录下的所有sql文件，并在指定目录下创建单独的csv文件。 github.com/dmitrydemin1973/powershell-oracle/blob/master/… 例如 .\run_export_all_tables.ps1 -username SCOTT -password tiger -connect_string ORCL -sql_path C:\export\sql\ -csv_path C:\export\csv\
