我需要在C＃程序中执行一大堆SQL语句（创建一堆表，视图和存储过程）。
这些语句需要用GO语句分隔，但SqlCommand.ExecuteNonQuery()不喜欢GO语句。我想我将发布以供参考的解决方案是在GO行分割SQL字符串，并分别执行每个批处理。
有更简单/更好的方式吗？
答案 0 :(得分：99)
使用了解GO分隔符的SQL Server管理对象（SMO）。请在此处查看我的博文：http://weblogs.asp.net/jongalloway/Handling-_2200_GO_2200_-Separators-in-SQL-Scripts-2D00-the-easy-way
示例代码：
public static void Main()
{
string scriptDirectory = "c:\\temp\\sqltest\\";
string sqlConnectionString = "Integrated Security=SSPI;" +
"Persist Security Info=True;Initial Catalog=Northwind;Data Source=(local)";
DirectoryInfo di = new DirectoryInfo(scriptDirectory);
FileInfo[] rgFiles = di.GetFiles("*.sql");
foreach (FileInfo fi in rgFiles)
{
FileInfo fileInfo = new FileInfo(fi.FullName);
string script = fileInfo.OpenText().ReadToEnd();
using (SqlConnection connection = new SqlConnection(sqlConnectionString))
{
Server server = new Server(new ServerConnection(connection));
server.ConnectionContext.ExecuteNonQuery(script);
}
}
}
如果这对您不起作用，请参阅菲尔·哈克的图书馆处理：http://haacked.com/archive/2007/11/04/a-library-for-executing-sql-scripts-with-go-separators-and.aspx
答案 1 :(得分：31)
这就是我为了解决眼前问题而共同努力的方法。
private void ExecuteBatchNonQuery(string sql, SqlConnection conn) {
string sqlBatch = string.Empty;
SqlCommand cmd = new SqlCommand(string.Empty, conn);
conn.Open();
sql += "\nGO"; // make sure last batch is executed.
try {
foreach (string line in sql.Split(new string[2] { "\n", "\r" }, StringSplitOptions.RemoveEmptyEntries)) {
if (line.ToUpperInvariant().Trim() == "GO") {
cmd.CommandText = sqlBatch;
cmd.ExecuteNonQuery();
sqlBatch = string.Empty;
} else {
sqlBatch += line + "\n";
}
}
} finally {
conn.Close();
}
}
它要求GO命令在他们自己的行上，并且不会检测块注释，所以这种事情会被拆分，并导致错误：
ExecuteBatchNonQuery(@"
/*
GO
*/", conn);

您可以使用SQL Management Objects执行此操作。这些是Management Studio用于执行查询的对象。我相信Server.ConnectionContext.ExecuteNonQuery()会表现你所需要的。
答案 3 :(得分：6)
“GO”批处理分隔符关键字实际上由SQL Management Studio本身使用，因此它知道在何处终止它发送到服务器的批处理，并且它不会传递给SQL服务器。如果您愿意，甚至可以在Management Studio中更改关键字。

基于Blorgbeard的解决方案。
foreach (var sqlBatch in commandText.Split(new[] { "GO" }, StringSplitOptions.RemoveEmptyEntries))
{
sqlCommand.CommandText = sqlBatch;
sqlCommand.ExecuteNonQuery();
}

如果您不想安装SMO对象，可以使用gplex工具（参见this answer）
答案 6 :(得分：3)
如果您不想使用SMO，例如因为您需要跨平台，您也可以使用SubText中的ScriptSplitter类。
Here's C＃＆amp; VB.NET
用法：
string strSQL = @"
SELECT * FROM INFORMATION_SCHEMA.columns
GO
SELECT * FROM INFORMATION_SCHEMA.views
";
foreach(string Script in new Subtext.Scripting.ScriptSplitter(strSQL ))
{
Console.WriteLine(Script);
}
如果您遇到多行c风格的评论问题，请使用正则表达式删除评论：
static string RemoveCstyleComments(string strInput)
{
string strPattern = @"/[*][\w\d\s]+[*]/";
//strPattern = @"/\*.*?\*/"; // Doesn't work
//strPattern = "/\\*.*?\\*/"; // Doesn't work
//strPattern = @"/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/ "; // Doesn't work
//strPattern = @"/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/ "; // Doesn't work
// http://stackoverflow.com/questions/462843/improving-fixing-a-regex-for-c-style-block-comments
strPattern = @"/\*(?>(?:(?>[^*]+)|\*(?!/))*)\*/"; // Works !
string strOutput = System.Text.RegularExpressions.Regex.Replace(strInput, strPattern, string.Empty, System.Text.RegularExpressions.RegexOptions.Multiline);
Console.WriteLine(strOutput);
return strOutput;
} // End Function RemoveCstyleComments

如果您不想使用SMO路线，可以搜索并将“GO”替换为“;”和你一样的查询。请注意，将返回最后一个结果集。
答案 8 :(得分：2)
我今天通过将我的SQL从文本文件加载到一个字符串中来完成此操作。然后我使用字符串Split函数将字符串分成单独的命令，然后将这些命令分别发送到服务器。简单：）
刚才意识到你需要拆分\ nGO以防万一GO字母出现在你的任何表名中等等。猜猜我很幸运！
答案 9 :(得分：2)
我也遇到了同样的问题，我找不到任何其他方法，只是将单个SQL操作拆分为单独的文件，然后按顺序执行所有这些操作。
显然问题不在于DML命令列表，它们可以在没有GO的情况下执行; DDL的不同故事（创建，更改，删除......）

如果您不想使用SMO（这比下面的解决方案更好，但我想提供替代方案......）您可以使用此功能拆分查询。

使用以下方法拆分字符串并逐批执行
using System;
using System.IO;
using System.Text.RegularExpressions;
namespace RegExTrial

class Program
{

string sql = String.Empty;
string path=@"D:\temp\sample.sql";
using (StreamReader reader = new StreamReader(path)) {
sql = reader.ReadToEnd();
}
//Select any GO (ignore case) that starts with at least
//one white space such as tab, space,new line, verticle tab etc
string pattern="[\\s](?i)GO(?-i)";
Regex matcher = new Regex(pattern, RegexOptions.Compiled);
int start = 0;
int end = 0;
Match batch=matcher.Match(sql);
while (batch.Success) {
end = batch.Index;
string batchQuery = sql.Substring(start, end - start).Trim();
//execute the batch
ExecuteBatch(batchQuery);
start = end + batch.Length;

答案 13 :(得分：0)
我在java中遇到了同样的问题，我用一点逻辑和正则表达式来解决它。我相信可以应用相同的逻辑。首先我从slq文件读入内存。然后我应用以下逻辑。它几乎已经说过了，但我相信使用正则表达式绑定比预期新行char更安全。
String pattern = "\\bGO\\b|\\bgo\\b";
String[] splitedSql = sql.split(pattern);
for (String chunk : splitedSql) {
getJdbcTemplate().update(chunk);
}
这基本上将sql字符串拆分为sql字符串数组。正则表达式基本上是检测完整的＆＃39; go＆＃39;单词或大写的单词。然后按顺序执行不同的查询。

我遇到了同样的问题并最终通过一个简单的字符串替换解决了它，用一个分号替换了GO（;）
在使用内联注释，块注释和GO命令执行脚本时，所有似乎都正常工作

{
using (StreamReader file = new StreamReader(filePath))
using (SqlConnection conn = new SqlConnection(dbConnStr))
{
StringBuilder sql = new StringBuilder();
string line;
while ((line = file.ReadLine()) != null)
{
// replace GO with semi-colon
if (line == "GO")
sql.Append(";");
// remove inline comments
else if (line.IndexOf("--") > -1)
sql.AppendFormat(" {0} ", line.Split(new string[] { "--" }, StringSplitOptions.None)[0]);
// just the line as it is
else
sql.AppendFormat(" {0} ", line);
}
conn.Open();
SqlCommand cmd = new SqlCommand(sql.ToString(), conn);
cmd.ExecuteNonQuery();

为了避免第三方，正则表达式，内存开销和使用大型脚本的快速工作，我创建了自己的基于流的解析器。它
可以使用 - 或/ ** /

可以使用'或'
识别字符串文字set @s =
'create table foo(...);
GO
create index ...';
和其他结构，如
gO -- commented text
