視覺工作室2013獲得關鍵字'表'附近的錯誤語法

Question

我正在建立一個網站使用Visual Studio 2013，我堅持讓用戶註冊，一旦提交細節存儲在數據庫中，經理可以登錄並查看所有註冊的帳戶。但我越來越

Error:System.Data.SqlClient.SqlException (0x80131904): Incorrect syntax near the keyword 'Table'. at System.Data.SqlClient.SqlConnection. 

BTW表是我存儲註冊帳戶數據的數據庫表的名稱。

任何幫助被佔用！

這是提交按鈕

Answer 1

另一件事的代碼就是爲什麼你需要檢查IsPostBack？

第一個Table在SQL將是一個Table語法。
如果必須使用的語法名稱....

的Microsoft SQL Server
修改您的SQL查詢從table到[table]

應該工作..

有你在SQL Management Studio中運行你的代碼？
我相信，如果你嘗試insert或select使用查詢

語法名稱必須的添加[]

Answer 2

我們不能在SQLSERVER使用表作爲表名， 改變你會打你的錯誤表名，它會起作用，不要忘記在查詢中也改變你的表名。

String insertQuery = "insert into changethistablename (Name, Date of birth, Yoga experience, Health issues, Email address, Telephone number, Password) values (@Name, @dob, @exp, @health, @email, @phone, @password)"; // inserts into table and declares data as variables// 
String checkuser = "select count(*) from changethistablename where Name= '"+ nameBox.Text +"'"; // checks wether the name entered is in the database already // 

Answer 3

兩件事情：

1）您使用表作爲表名。由於它已經是SQL中的關鍵字，所以請更改此名稱。雖然您可以使用以下命令：

Insert into [Table].... 

2）您的列名稱包含空格，所以它可能會導致一些錯誤。如果列名包含空格，請在列名周圍使用括號。

String insertQuery = "insert into Table (Name, [Date of birth], [Yoga experience], [Health issues], [Email address], [Telephone number], Password) values (@Name, @dob, @exp, @health, @email, @phone, @password)";
