SQLServer數據庫每個數據庫都有INFORMATION_SCHEMA視圖，數據庫的結構信息Schema都在這里存儲。

select TABLE_NAME,TABLE_TYPE,TABLE_CATALOG,TABLE_SCHEMA from INFORMATION_SCHEMA.TABLES;

select COLUMN_NAME,DATA_TYPE,CHARACTER_MAXIMUM_LENGTH,IS_NULLABLE from INFORMATION_SCHEMA.COLUMNS t where t.TABLE_NAME = 'StoreType';

? ? ? ? private void button4_Click(object sender, EventArgs e){string sql = "";DataTable dtTmp = null;//取出表名sql = "select * from INFORMATION_SCHEMA.TABLES;";dtTmp = SQLSERVER_DB_Helper.GetDataTable(sql);foreach(DataRow dr in dtTmp.Rows){String tableName = dr["TABLE_NAME"].ToString();System.Console.WriteLine(tableName);//字段名string sql_1 = "select * from INFORMATION_SCHEMA.COLUMNS t where t.TABLE_NAME = '" + tableName + "';";DataTable dttTmp = SQLSERVER_DB_Helper.GetDataTable(sql_1);foreach (DataRow drr in dttTmp.Rows){String columnName = drr["COLUMN_NAME"].ToString();System.Console.WriteLine("\t" + columnName);}}}
