SQL Server 数据库中表名和字段名全部改为大写的批处理方法（原创）

 由于Oracle数据库中表和字段名的特殊要求，需要将表名和字段名全部改为大写，才能准确的导入到Oracle中。

我的思路是首先在通过C#语言生成批处理的存储过程，然后执行存储过程。

在SQL sever中，修改表名和字段名的SQL语句格式如下图：

一下代码为生成批处理字符串的方法，并保存到了strtest中。

        /// <summary>  
        /// 获取列名  
        /// </summary>  
        /// <param name="connection"></param>  
        /// <returns></returns>  
        public List<string> GetTables(string connection)
        {
            List<string> tablelist = new List<string>();
            SqlConnection objConnetion = new SqlConnection(connection);
            try
            {
                if (objConnetion.State == ConnectionState.Closed)
                {
                    objConnetion.Open();
                    DataTable objTable = objConnetion.GetSchema("Tables");
                    foreach (DataRow row in objTable.Rows)
                    {
                        tablelist.Add(row[2].ToString());
                    }
                }
            }
            catch
            {

            }
            finally
            {
                if (objConnetion != null && objConnetion.State == ConnectionState.Closed)
                {
                    objConnetion.Dispose();
                }

            }
            return tablelist;
        }

        /// <summary>  
        /// 获取字段  
        /// </summary>  
        /// <param name="connection"></param>  
        /// <param name="TableName"></param>  
        /// <returns></returns>  
        public List<string> GetColumnField(string connection, string TableName)
        {
            List<string> Columnlist = new List<string>();
            SqlConnection objConnetion = new SqlConnection(connection);
            try
            {
                if (objConnetion.State == ConnectionState.Closed)
                {
                    objConnetion.Open();
                }

                SqlCommand cmd = new SqlCommand("Select Name FROM SysColumns Where id=Object_Id('" + TableName + "')", objConnetion);
                SqlDataReader objReader = cmd.ExecuteReader();

                while (objReader.Read())
                {
                    Columnlist.Add(objReader[0].ToString());
                }
            }
            catch
            {

            }
            objConnetion.Close();
            return Columnlist;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string sqlstr;
            string strConn;
            strConn = "Server=PC--20101007WET\\SQLEXPRESS;Integrated Security=SSPI;Database=GxDataCollectorDB";

            List<string> dd;
            dd = GetTables(strConn);
           
            int i;
            int j;
            string strTmp = "";
            string LcaseName;
            string UcaseName;

            string strLcaseFieldName;
            string strUcaseFieldname;

            string strTest = "";

            for (i = 0; i < dd.Count; i ++ )
            {
                LcaseName = dd[i].ToString();
                List<string> cc;
                cc = GetColumnField(strConn, LcaseName);

                //重命名字段名
                for (j = 0; j < cc.Count; j ++ )
                {
                    strLcaseFieldName = cc[j].ToString();
                    strUcaseFieldname = strLcaseFieldName.ToUpper();

                    if (strLcaseFieldName != strUcaseFieldname)
                    {
                        sqlstr = "EXEC sp_rename '" + LcaseName + "." + strLcaseFieldName + "','" + strUcaseFieldname + "','COLUMN'";
                        strTest = strTest + sqlstr + "\r\n";
                    }
                }

                //重命名表名
                //LcaseName = dd[i].ToString();
                //UcaseName = LcaseName.ToUpper();
                //if (LcaseName != UcaseName)
                //{
                //    sqlstr = "EXEC sp_rename '" + LcaseName + "','" + UcaseName + "'";
                //    strTest = strTest + sqlstr + "\r\n";
                //}
            }
            MessageBox.Show("成功！");
        } 

在生成后，将以上代码拷贝到SQL Server企业管理器的查询分析器中，并选择当前数据库，具体如下图所示：

然后执行就行，以上修改表名，修改字段名类似，不在赘述了。
