搜索时从SQL结果中删除空格

Question

I have an Access database that contains fields with spaces in them. I'm trying to allow a user to search for matches but the spaces in the results are returning no information.

var dtCustomers = new DataTable();
var adapter = new OleDbDataAdapter("SELECT * FROM Devices WHERE [Serial Number]='" + textBox1.Text + "'", conn);
adapter.Fill(dtCustomers);
dataGridView1.DataSource = dtCustomers;
foreach (DataGridViewRow row in dataGridView1.Rows)
{
    row.Cells[0].Style.ForeColor = Color.Blue;
    row.Cells[28].Style.ForeColor = Color.Red;
}

The code above will return results from the database but if the database has a field that's entered as '1Z 4568 29z4h' then it won't be returned unless the user types it exactly like that. The results are displayed in a DataGridView. Is there a different query I should be using?

You can use SQL's replace function to replace all spaces in [Serial Number] column to nothing, and use textBox1.Text.Replace(' ','') to make sure the user's input doesn't have spaces too:

var dtCustomers = new DataTable();
var adapter = new OleDbDataAdapter(@"SELECT * FROM Devices WHERE replace([Serial Number], " ", "")='" + textBox1.Text.Relpace(' ','') + "'", conn);
adapter.Fill(dtCustomers);
dataGridView1.DataSource = dtCustomers;
foreach (DataGridViewRow row in dataGridView1.Rows)
{
    row.Cells[0].Style.ForeColor = Color.Blue;
    row.Cells[28].Style.ForeColor = Color.Red;
}
