[英]Sql insert using C# - Column name or number of supplied values does not match table definition
[英]SQL Server Insert Error: Column name or number of supplied values does not match table definition c#
我想使用Visual Studio 2015將數據添加到表中,但出現此錯誤:
An exception of type "System.Data.SqlClient.SqlException" occurred in System.Data.dll but was not processed in user code
Column name or number of supplied values does not match table definition.
這是我的代碼:
protected void btSignup_Click(object sender, EventArgs e)
{
String CS = ConfigurationManager.ConnectionStrings["MyDatabaseConnectionString1"].ConnectionString;
using (SqlConnection con = new SqlConnection(CS))
{
SqlCommand cmd = new SqlCommand("insert into Users values('" + tbUname.Text + "','" + tbPass.Text + "','" + tbEmail.Text + "','" + tbName.Text + "')",con);
con.Open();
cmd.ExecuteNonQuery();
}
}
這是您的代碼:
insert into User
values('" + tbUname.Text + "','" + tbPass.Text + "','" + tbEmail.Text + "','" + tbName.Text + "')"
使用insert
,應始終包括列名。 並且,將值放入查詢字符串時,應使用參數。
修復代碼后,您的問題將消失。
