背景：1.前台：JQUERY 提交数据
2.后台：OWIN C# 处理接收数据
3.数据库： postgresql
============================================
问题描述： 后台接收到前台的数据，拼装一个 SQL 语句
update wbs_data
set work_data=‘{"proName":"科研GOOD","proCode":"科研项目001","unitProName":"No1","drawingNo":"734116","proAddress":"大庆",
"partsComponents":"让胡路锅底",
"checkContent":"<p><br/> 这是一测试图片<img src=\"/upload/8096b2b7d0a20cf4cd425f7a7f094b36adaf995e.jpg\" alt=\"\"
width=\"200\" height=\"200\" /> <br/></p>",
"checkOpinion":"检查意见：<br/>1.好<br/>2.很好<br/>3.非 常好","materialDocs":"原材料质量文件：<br/>1.测试文件1<br/>2.测试文件2",
"monitor":"","deputy":"","superEngineer":"","techLeader":"","date1":"","date2":"","date3":""}‘,work_state=1
where pwbs_id=124
我在后台C# 用 Npgsql
public static string executeSQL(string strSQL)
{
Console.WriteLine("{0}", strSQL);
string returnValue = string.Empty;
NpgsqlConnection connection = new NpgsqlConnection(getConnectionString());
NpgsqlCommand command = new NpgsqlCommand();
command.Connection = connection;
command.CommandText = strSQL;
try
{
connection.Open();
command.ExecuteNonQuery();
//returnValue = "{\"SUCCESS\":\"执行操作：‘" + strSQL + "‘成功！\"}";
Console.WriteLine("{0}","--------------------you are lucky----------------");
returnValue = "{\"SUCCESS\":\"操作成功！\"}";
}
catch (Exception err)
{
returnValue = "{\"ERROR\":\"发生以下错误：" + err.Message.ToString() + "\"}";
}
finally
{
connection.Close();
}
return returnValue;
}
执行时总是报错：invalid input syntax for type json
奇怪的是，当我把这个拼装的SQL语句放在后台服务上PSQL 运行时，居然还通过了！
why??????
