SQL 服务器迁移 2008 到 2016 - raiserror 语法错误

Question

我们要从 SQL Server 2008 迁移到 2016。我正在识别错误，我在触发器中收到以下错误：

Incorrect syntax near '51001'.

我查看了 Microsoft 网站上的 Raiserror 文档，但没有帮助。下面是SQL。任何帮助将不胜感激。

IF (SELECT count(*) FROM dbo.u_sample_concrete ref, deleted
WHERE  ref.lab_cd =  deleted.lab_id) > 0
BEGIN
    RAISERROR 51001 ''Trigger td_tblLAB on table dbo.tblLAB:  Primary key values found in table dbo.u_sample_concrete (lab_cd).  Delete restricted; the transaction is being rolled back.''
    ROLLBACK TRANSACTION
    RETURN
END

Answer 1

Microsoft Documentation 确实表明您的陈述有 4 个错误。

参数必须在方括号内 raiserror().
使用 msd_id (51001) 时需要 4 个参数 - 您提供的是 2.
参数之间用逗号分隔,.
您将字符串用双引号引起来，而它应该是单引号。

RAISERROR (51001, -1,- 1, 'Trigger td_tblLAB on table dbo.tblLAB:  Primary key values found in table dbo.u_sample_concrete (lab_cd).  Delete restricted; the transaction is being rolled back.')

注意：现在最好使用 throw 而不是 raiserror。

使用正确的语法添加到@DaleK 的答案中，问题 RAISERRROR 语法早已过时。 IIRC，它在 20 年前被弃用（在 SQL Server 2000 版本中）并在 SQL Server 2012 中完全删除。

下面是一个 powershell 脚本，它使用 T-SQL Script DOM (also available with the Dacfx NuGet package) 来识别具有无效语法的现有 T-SQL 模块。不过，它不会捕获动态 SQL 中的问题。

$connectionString = "Data Source=.;Initial Catalog=YourDatabase;Integrated Security=SSPI"

try {

    $query = @"
SELECT 
      QUOTENAME(OBJECT_SCHEMA_NAME(object_id)) + N'.' + QUOTENAME(OBJECT_NAME(object_id)) AS ObjectName
    , OBJECTPROPERTY(object_id, 'ExecIsQuotedIdentOn') AS ExecIsQuotedIdentOn
    , definition 
FROM sys.sql_modules;
"@

    Add-Type -Path "C:\Program Files (x86)\Microsoft SQL Server0\DAC\bin\Microsoft.SqlServer.TransactSql.ScriptDom.dll"

    $connection = New-Object Data.SqlClient.SqlConnection($connectionString)
    $command = New-Object Data.SqlClient.SqlCommand($query, $connection)
    $connection.Open()
    $reader = $command.ExecuteReader()
    while ($reader.Read()) {

        # use TSqlParser appropriate for your SQL Server version
        $parser = New-Object Microsoft.SqlServer.TransactSql.ScriptDom.TSql130Parser($reader["ExecIsQuotedIdentOn"])
        $parseErrors = New-Object Collections.Generic.List[Microsoft.SqlServer.TransactSql.ScriptDom.ParseError]
        $scriptReader = New-Object IO.StringReader($($reader["definition"]))

        Write-Host "Parsing $($reader["ObjectName"]) ..."
        [void]$parser.Parse($scriptReader, [ref]$parseErrors)
        if($parseErrors.Count -ne 0) {
            Write-Host "Parsing errors for object $($reader["ObjectName"]): $($parseErrors | ConvertTo-Json)" -ForegroundColor Yellow
        }

    }
    $connecton.Close()
}    
catch {
    throw
}
