Question

此查询有问题吗？

"UPDATE tb_EmployeeMasterList SET [EmployeeID] = " + txt_EmpId.Text +", [LastName] = '" + txt_LN.Text + "', [FirstName] = '" + txt_FN.Text + "', [MiddleName] = '" + txt_MN.Text + "', [PositionOrSkill] = '" + txt_PorS.Text + "', [BasicSalary] = " + txt_Basic.Text + ", [Allowance] = " + txt_Allow.Text + ", [Total] = " + total + ", [EPAproposedBonus] = " + txt_Bonus.Text + ", [Remarks] = '" + txt_Remarks.Text + "' WHERE ([LastName] = '" + LN + "' AND [FirstName] = '" + FN + "');"

我继续单独在该查询上获取语法错误。

Answer 1

似乎缺少一对单引号：

"UPDATE tb_EmployeeMasterList SET [EmployeeID] = " + txt_EmpId.Text +",

应该是：

"UPDATE tb_EmployeeMasterList SET [EmployeeID] = '" + txt_EmpId.Text +"',

Answer 2

尝试触发不带括号的WHERE语句

"UPDATE tb_EmployeeMasterList SET [EmployeeID] = " + txt_EmpId.Text +", [LastName] = '" + txt_LN.Text + "', [FirstName] = '" + txt_FN.Text + "', [MiddleName] = '" + txt_MN.Text + "', [PositionOrSkill] = '" + txt_PorS.Text + "', [BasicSalary] = " + txt_Basic.Text + ", [Allowance] = " + txt_Allow.Text + ", [Total] = " + total + ", [EPAproposedBonus] = " + txt_Bonus.Text + ", [Remarks] = '" + txt_Remarks.Text + "' WHERE [LastName] = '" + LN + "' AND [FirstName] = '" + FN + "';"

Answer 3

如果total，LN和FN值来自变量而不是文本框，那么语法就可以了，但Textbox会在它们之后添加.Text，否则会出现语法错误。
