我花了一点时间，对 Matt Roberts / Wangzq 解决方案进行了小修改，没有 DECLAREs 部分，您可以在 .NET Fiddle 或 download LINQPad 5 file 上试用。
输入：
exec sp_executesql N'UPDATE MyTable SET [Field1] = @0, [Field2] = @1',N'@0 nvarchar(max) ,@1 int',@0=N'String',@1=0
输出：
UPDATE MyTable SET [Field1] = N'String', [Field2] = 0
代码：
using System;
using System.Linq;
using System.Text.RegularExpressions;
public class Program
{
public static void Main()
{
var sql = @"exec sp_executesql N'UPDATE MyTable SET [Field1] = @0, [Field2] = @1',N'@0 nvarchar(max) ,@1 int',@0=N'String',@1=0";
Console.WriteLine(ConvertSql(sql));
}
public static string ConvertSql(string origSql)
{
var re = new Regex(@"exec*\s*sp_executesql\s+N'([\s\S]*)',\s*N'(@[\s\S]*?)',\s*([\s\S]*)", RegexOptions.IgnoreCase); // 1: the sql, 2: the declare, 3: the setting
var match = re.Match(origSql);
if (match.Success)
{
var sql = match.Groups[1].Value.Replace("''", "'");
//var declare = match.Groups[2].Value;
var setting = match.Groups[3].Value + ',';
// to deal with comma or single quote in variable values, we can use the variable name to split
var re2 = new Regex(@"@[^',]*?\s*=");
var variables = re2.Matches(setting).Cast<Match>().Select(m => m.Value).ToArray();
var values = re2.Split(setting).Where(s=>!string.IsNullOrWhiteSpace(s)).Select(m => m.Trim(',').Trim().Trim(';')).ToArray();
for (int i = variables.Length-1; i>=0; i--)
{
sql = Regex.Replace(sql, "(" + variables[i].Replace("=", "")+")", values[i], RegexOptions.Singleline);
}
return sql;
}
return @"Unknown sql query format.";
}
}
