我的代码如下： -

My code is as follows:-

con.Open();
                string quer = "insert into Table1([Invoice Number],Date,Product,[Serail Number],Status, Amount) Select Top(1) Inventory where Product='" + TextBox10.Text + "'";
                SqlCommand cmdd = new SqlCommand(quer, con);
                cmdd.ExecuteNonQuery();
                con.Close();<pre lang="c#">

推荐答案

尝试使用

try with

string quer = "insert into Table1([Invoice Number],Date,Product,[Serail Number],Status, Amount) Select Top(1) [Invoice Number],Date,Product,[Serail Number],Status, Amount from Inventory where Product='" + TextBox10.Text + "'";

$您需要b $ b可能需要在sql select语句的第二部分中指定列名和from关键字。 baically语法将是

you need may need to specify the column names and "from" keyword in the second part of the sql select statement. baically syntax would be

-- Option 1:
INSERT INTO table1 (column names....)
SELECT TOP (1) column names....
FROM table2

-- Option 2:
INSERT TOP (1) INTO table1 (column names....)
SELECT column names....
FROM table2

你最好使用参数terized sql语句而不是连接字符串以避免sql注入攻击。

you better use parameterized sql statement rather than concatenating strings to avoid sql injection attacks.

INSERT TOP(1) INTO Table1 
SELECT * FROM Inventory where Product = '" + TextBox10.Text + "'"
