c# - 使用 C# 在 SQL Server 上执行 sql 文件

Question

我正在尝试创建一种在 SQL Server 数据库上运行 .sql 文件的方法。

我的代码是:

SqlConnection dbCon = new SqlConnection(connstr);
FileInfo file = new FileInfo(Server.MapPath("~/Installer/JobTraksDB.sql"));
StreamReader fileRead = file.OpenText();
string script = fileRead.ReadToEnd();
fileRead.Close();

SqlCommand command = new SqlCommand(script, dbCon);
try
{
    dbCon.Open();
    command.ExecuteNonQuery();
    dbCon.Close();
}
catch (Exception ex)
{
    throw new Exception("Failed to Update the Database, check your Permissions.");
}

但我不断收到有关“关键字‘GO’附近语法不正确”的错误消息我的 SQL 文件是这样开始的:(从 SQL Management Studio 生成)

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[Job_Types](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [Name] [varchar](50) NOT NULL,
 CONSTRAINT [PK_JobTypes] PRIMARY KEY CLUSTERED 
(
    [ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
SET ANSI_PADDING OFF
GO

我应该如何执行这个脚本？

Answer 1

我们是这样做的:

    protected virtual void ExecuteScript(SqlConnection connection, string script)
    {
        string[] commandTextArray = System.Text.RegularExpressions.Regex.Split(script, "\r\n[\t ]*GO");

        SqlCommand _cmd = new SqlCommand(String.Empty, connection);

        foreach (string commandText in commandTextArray)
        {
            if (commandText.Trim() == string.Empty) continue;
            if ((commandText.Length >= 3) && (commandText.Substring(0, 3).ToUpper() == "USE"))
            {
                throw new Exception("Create-script contains USE-statement. Please provide non-database specific create-scripts!");
            }

            _cmd.CommandText = commandText;
            _cmd.ExecuteNonQuery();
        }

    }

使用一些文件读取功能加载脚本的内容。
