利用webService上传数据(SQL Server 上传到oracle数据库)

 客户端代码

首先定义客户端的数据库(sql Server) 中一个表

ChangeLogForSyncID uniqueidentifier Unchecked
EventID int Unchecked (自增)
Isupload bit Unchecked
OperateType int Checked (增删改)
BusinessType int Checked (具体业务)
BusinessID varchar(100) Checked (业务ID)
OperateTime datetime Unchecked

 

WebService 端定义上传数据格式(也是一个树形结构表)

public class TransportDataTable { public Busi<a href="/tag/nes/" target="_blank" class="keywords">nes</a>sType Busi<a href="/tag/nes/" target="_blank" class="keywords">nes</a>sType { get; set; } public string TableName { get; set; } public TableOperateType tableOperateType; private string[] keyFields = new string[0]; public string[] KeyFields { get { return keyFields; } set { keyFields = value; } } private string[] parentFields = new string[0]; public string[] ParentFields { get { return parentFields; } set { parentFields = value; } } private TransportColumn[] columns = new TransportColumn[0]; public TransportColumn[] Columns { get { return columns; } set { columns = value; } } private TransportDa<a href="/tag/Taro/" target="_blank" class="keywords">Taro</a>w[] rows = new TransportDa<a href="/tag/Taro/" target="_blank" class="keywords">Taro</a>w[0]; public TransportDa<a href="/tag/Taro/" target="_blank" class="keywords">Taro</a>w[] Rows { get { return rows; } set { rows = value; } } private TransportDataTable[] children = new TransportDataTable[0]; public TransportDataTable[] Children { get { return children; } set { children = value; } } public TransportDataTable() { } }

具体实现

客户端通过配置 表名,列名,主键,字表,业务类型(这里只做两种类型,同步(插入和修改是一种操作)和删除),主键在字表的名称(这里可能就是主键在字表的名称会发生变化) protected TransportDataTable CreateTable(BaseUploadCon<a href="/tag/fig/" target="_blank" class="keywords">fig</a> con<a href="/tag/fig/" target="_blank" class="keywords">fig</a>) { TransportDataTable table = new TransportDataTable(); table.KeyFields = con<a href="/tag/fig/" target="_blank" class="keywords">fig</a>.KeyFields; table.TableName = con<a href="/tag/fig/" target="_blank" class="keywords">fig</a>.TableName.ToLower(); string columns = string.Join(",",con<a href="/tag/fig/" target="_blank" class="keywords">fig</a>.ColumnName); string dbcolumns = "'" + string.Join("','",con<a href="/tag/fig/" target="_blank" class="keywords">fig</a>.ColumnName) + "'"; table.Columns = GetTransportColumn(con<a href="/tag/fig/" target="_blank" class="keywords">fig</a>.TableName,dbcolumns); if (con<a href="/tag/fig/" target="_blank" class="keywords">fig</a>.OperateType == Busi<a href="/tag/nes/" target="_blank" class="keywords">nes</a>sOperateType.Delete) table.tableOperateType = TableOperateType.Delete; else table.tableOperateType = TableOperateType.Sync; string[] busi<a href="/tag/nes/" target="_blank" class="keywords">nes</a>sIDArr = con<a href="/tag/fig/" target="_blank" class="keywords">fig</a>.Busi<a href="/tag/nes/" target="_blank" class="keywords">nes</a>sID.Split(','); string[] KeyFieldsArr = con<a href="/tag/fig/" target="_blank" class="keywords">fig</a>.KeyFields; StringBuilder sb = new StringBuilder(); for (int i = 0; i < KeyFieldsArr.Length; i++) { sb.AppendFormat("{0}='{1}'",KeyFieldsArr[i],busi<a href="/tag/nes/" target="_blank" class="keywords">nes</a>sIDArr[i]);

自动构造树形数据;构造树形数据代码在此;

 

需要注意的是oracle 和sql  日期处理不同

这里根据数据库字典查询某一个表里的所有列

private TransportColumn[] GetTransportColumn(string tableName,string columns) { ArrayList arr = new ArrayList(); string <a href="/tag/sql/" target="_blank" class="keywords">sql</a> = "select o.name as tbname,c.name as columnname,t.name as columntype" + " from sys.tables as o" + " join sys.columns as c" + " on o.object_id=c.object_id" + " join sys.types as t" + " on c.sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>_type_id=t.sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>_type_id where o.name='" + tableName + "' and c.name in (" + columns.ToLower() + ")"; using (<a href="/tag/sql/" target="_blank" class="keywords">sql</a>DataReader sdr = <a href="/tag/sql/" target="_blank" class="keywords">sql</a>Helper.ExecuteReader(CommandType.Text,<a href="/tag/sql/" target="_blank" class="keywords">sql</a>,null)) { while (sdr.Read()) { TransportColumn col = new TransportColumn(); col.fieldName = sdr["columnname"].ToString().ToLower(); col.fieldType = GetColumnType(sdr["columntype"].ToString(),col.fieldName); arr.Add(col); } } return (TransportColumn[])arr.ToArray(typeof(TransportColumn)); }
