sql - 如何将列表作为参数从powershell插入到SqlPlus

问题描述

我在文件中有一个这样的查询：

脚本.sql

select * 
from test_table
where name in (&1)

这是我正在尝试进行的查询示例

我用一个像这样的power shell脚本执行它：

$names = '''Name1'', ''Name2'''
$params = '"' + $names + '"'
sqlplus -silent $username/$password@$tnsalias "@script.sql" $params

请注意，$names有一个可变的名称列表

但是当脚本执行时，参数会像这样替换：

former : where name in (&1)
new    : where name in (Name1)

当然，SQL 会引发错误。

为什么它会像这样替换参数？

我怎样才能实现我想做的事情，所以第一个参数是将在where name in(&1)子句中使用的字符串列表。我的目标是 sql 将是 where name in ('Name1', 'Name2')

如果有帮助，SQL 将在 Oracle 11 上执行。

解决方案

powershell 示例

$username_dba = "system"
$password_dba = "manager"
$tnsalias_db = "es"
$names = "'''Name1'',''Name2'', ''X'''"
$params = '"' + $names + '"'
$sqlfile = "@sqltest.sql"

Write-Host  $names
Write-Host  $params

C:\oracle\instantclient_11_2\sqlplus  $username_dba/$password_dba@$tnsalias_db  $sqlfile  $params

输出powershell：

C:\upwork\stackoverflow\param_sql>powershell .\sql_param.ps1
'''Name1'',''Name2'', ''X'''
"'''Name1'',''Name2'', ''X'''"
