Powershell：PSSQLITE：复杂 SQL 不支持

Question

Powershell 版本：5.1 PSSQLITE 版本：1.1.0

我有一个 SQL 在 SQLITE 中运行。

1. 如果我通过 Squirrel SQL 连接，它工作正常
2. 如果我用 PSSQLIte 在 PS 中运行它，会弹出如下错误：

Invoke-SqliteQuery : Exception calling "Fill" with "1" argument(s): "SQL logic error or missing database
near "(": syntax error"
At line:11 char:8
+ return Invoke-SqliteQuery -DataSource $sourceDB -Query $sql
+        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Write-Error], WriteErrorException
    + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Invoke-SqliteQuery

这是否意味着 pssqlite 对 SQL 的支持有限？

这是我的完整代码供您参考：创建表

CREATE TABLE REVIEW_LOGS(
NUMBER TEXT,
TYPE TEXT,
DATE TEXT,
Reviewee TEXT,
Reviewer TEXT,
TICKET_NUMBER TEXT,
SHORT_DESCRIPTION TEXT,
DURATION INTEGER,
TOPICS_COVERED TEXT,
OUTPUT TEXT,
TO_BE_IMPROVED TEXT,
ACTION_ITEM TEXT,
Adjusted_Issue_Communication TEXT,
ASAT TEXT default current_timestamp
)   

在 SQLITE 中执行 SQL

function execute-sql
{
    Param(
            [Parameter(Mandatory=$true)]
            [String]$sql,
            [String]$sourceDB = 'c:\data\cwd\ticketlogs.db'             
    )
    
    try{
            $sql |out-file tttt.log -append
            return Invoke-SqliteQuery -DataSource $sourceDB -Query $sql 
        }catch {
            Write-Host $sql
    }
    
}

问题SQL

SELECT Metric, count, percentage FROM
(
SELECT Metric, count, percentage, rank() over(PARTITION  by Metric order by count desc) as rank
FROM(
    select Adjusted_Issue_Communication as Metric, count(*)as count , 
              round(count(*)*1.0/(select count(*) from review_logs where date between '2021-01-01'  and '2021-01-31' )*100, 2)|| '%' as percentage
            from review_logs where date between '2021-01-01' and '2021-01-31' group by 1 
    Union
    SELECT 'N/A'  as Metric, 0 as count, "0.0%" as percentage 
    Union
    SELECT 'Yes'  as Metric, 0 as count, "0.0%" as percentage 
    Union
    SELECT 'No'  as Metric, 0 as count, "0.0%" as percentage 
    )
)where rank = 1
order by Metric;

Answer 1

我也尝试使用 rank() 并且失败了。 发现为 PSSQLite 记录的此问题指出 PS5 版本正在使用旧的 sqlite 二进制文件，其中不包括排名和其他分析函数，但 PS Core 二进制文件已更新。 我在 Powershell 版本 7.1.2 和在 PS 5.1 中失败的相同命令中进行了测试

Invoke-SqliteQuery -DataSource .\email.db -Query 'select rank() over (partition by Name order by name) as Ranks from email;'

曾在 Powershell 7.1.2
