我已执行上述查询,但收到错误:
{System.Data.OleDb.OleDbException: Syntax error. in query expression
'Select [UserID] from UserDetails'
我的示例代码如下:
OleDbCommand cmd1 = new OleDbCommand("Insert into UserCompanyDetails([UserID],[CompanyID]) values (" + "Select [UserID] from UserDetails" + "," + "Select @@identity" + ");", conn);
conn.Open();
cmd1.ExecuteNonQuery();
conn.Close();
为什么我收到此错误?
答案 0 :(得分:0)
您应该将子查询放在括号中:
"Insert into UserCompanyDetails([UserID],[CompanyID]) values ((Select [UserID] from UserDetails),(Select @@identity))"
答案 1 :(得分:0)
另一种方法:
尝试将以下查询的结果保存在各自数据类型的变量中。
Select [UserID] from UserDetails
Select @@identity
然后,您只需在主查询字符串
中使用这些变量即可
