【问题描述】:
我有以下代码:
const string Sql =
@"select distinct [name]
from tblCustomers
left outer join tblCustomerInfo on tblCustomers.Id = tblCustomerInfo.CustomerId
where (tblCustomer.Name LIKE '%@SEARCH%' OR tblCustomerInfo.Info LIKE '%@SEARCH%');";
using (var command = new SqlCommand(Sql, Connection))
{
command.Parameters.AddWithValue("@SEARCH", searchString);
...
}
这个不行,我也试过了:
const string Sql =
@"select distinct [name]
from tblCustomers
left outer join tblCustomerInfo on tblCustomers.Id = tblCustomerInfo.CustomerId
where (tblCustomer.Name LIKE @SEARCH OR tblCustomerInfo.Info LIKE @SEARCH );";
using (var command = new SqlCommand(Sql, Connection))
{
command.Parameters.AddWithValue("@SEARCH", "'%" + searchString + "%'");
...
}
但这也不起作用。出了什么问题?有什么建议吗?
