Question

在C＃中运行此XML SQL时发生错误。缺什么？它在SQL Server管理工作室中运行良好，但在c＃中没有。

protected DataTable ServiceCodes(string orderColumn = default(string), bool orderAscending = true)
{
    string sql = @" SELECT DISTINCT(Split.a.value('.', 'VARCHAR(100)')) AS Data  
                             FROM  
                             (
                                 SELECT CAST('<M>' + REPLACE(Text09, ',', '</M><M>') + '</M>' AS XML) AS Data  
                                 FROM  Assets
                                 WHERE Category = 'Service'
                             ) AS A CROSS APPLY Data.nodes ('/M') AS Split(a) ORDER BY Data";

    return DatabaseConnection.ExecuteDataTable(sql, 120000);
}

我认为您Text09列中有一些特殊字符。试试这个：

SELECT DISTINCT(Split.a.value('.', 'VARCHAR(100)')) AS Data  
FROM  
(
 SELECT CAST('<M>' + replace((select Text09 + '' for xml path('')), ',', '</M><M>') + '</M>' AS XML) AS Data  
 FROM  Assets
 WHERE Category = 'Service'
) AS A CROSS APPLY Data.nodes ('/M') AS Split(a) ORDER BY Data
