Answer 1

只運行這些查詢的圖2中，第一會給你列名，第二會給你你尋找的特定身份證的行。一旦獲得這些數據，使用System.Data.SqlClient.SqlConnection從這些數據創建表格應該非常簡單。

columnNamesQuery = "SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = N'YourTableName'"; 

dataQuery = "SELECT * FROM YourTableName WHERE id = 1"; 

Answer 2

select 'amt1' particulars, amt1 amount from t1 where id=1 
union 
select 'amt2' particulars, amt2 amount from t1 where id=1 
union 
select 'amt3' particulars, amt3 amount from t1 where id=1 
union 
select 'amt4' particulars, amt4 amount from t1 where id=1
