我确信这个问题已经得到了回答,但是我无法使用搜索工具找到答案。
使用c#,我想运行一个.sql文件。sql文件包含多个sql语句,其中一些语句被分成多行。我尝试读取文件,并尝试使用ODP.NET执行文件...然而,我并不认为ExecuteNonQuery真的是为此而设计的。
所以我试着通过派生一个进程来使用sqlplus ...但是,除非我在UseShellExecute设置为true的情况下生成进程,否则sqlplus将挂起并且永远不会退出。下面是不起作用的代码。
Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "sqlplus";
p.StartInfo.Arguments = string.Format("xx/xx@{0} @{1}", in_database, s);
p.StartInfo.CreateNoWindow = true;
bool started = p.Start();
p.WaitForExit();
WaitForExit永远不会回来..。除非我将UseShellExecute设置为true。UseShellExecute的一个副作用是您无法捕获重定向的输出。

我用Microsoft.SqlServer.Management尝试了这个解决方案,但它在.NET 4.0上不能很好地工作,所以我只用.NET libs框架写了另一个解决方案。
string script = File.ReadAllText(@"E:\someSqlScript.sql");
// split script on GO command
IEnumerable<string> commandStrings = Regex.Split(script, @"^\s*GO\s*$", RegexOptions.Multiline | RegexOptions.IgnoreCase);
Connection.Open();
foreach (string commandString in commandStrings)
{
if (!string.IsNullOrWhiteSpace(commandString.Trim()))
{
using(var command = new SqlCommand(commandString, Connection))
{
command.ExecuteNonQuery();
}
}
}
Connection.Close();

这适用于Framework 4.0或更高版本。支持GO。还会显示错误消息、行和sql命令。
using System.Data.SqlClient;
private bool runSqlScriptFile(string pathStoreProceduresFile, string connectionString)
{
try
{
string script = File.ReadAllText(pathStoreProceduresFile);
// split script on GO command
System.Collections.Generic.IEnumerable<string> commandStrings = Regex.Split(script, @"^\s*GO\s*$",
RegexOptions.Multiline | RegexOptions.IgnoreCase);
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
foreach (string commandString in commandStrings)
{
if (commandString.Trim() != "")
{
using (var command = new SqlCommand(commandString, connection))
{
try
{
command.ExecuteNonQuery();
}
catch (SqlException ex)
{
string spError = commandString.Length > 100 ? commandString.Substring(0, 100) + " ...\n..." : commandString;
MessageBox.Show(string.Format("Please check the SqlServer script.\nFile: {0} \nLine: {1} \nError: {2} \nSQL Command: \n{3}", pathStoreProceduresFile, ex.LineNumber, ex.Message, spError), "Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning);
return false;
}
}
}
}
connection.Close();
}
return true;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning);
return false;
}
}
