    <p>I have a button in my windows forms which UPDATES every table. However, I am getting error SQLException was unhandled. Incorrect syntax near '='.</p> <p>This is my code in Update Button:</p> <pre><code> public void btnUpdate_Click(object sender, EventArgs e) { foreach (DataGridViewRow row in dataGridView1.Rows) { try { //MessageBox.Show(row.Cells[7].FormattedValue.ToString()); System.Data.SqlClient.SqlConnection sqlConnection1 = new System.Data.SqlClient.SqlConnection("server=Test\\Test; Integrated Security=true; Database=Testing;"); System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand(); cmd.CommandType = System.Data.CommandType.Text; cmd.CommandText = "UPDATE dbo.JobStatus SET ShipTrackingNumber = '" + row.Cells[7].FormattedValue.ToString() + "' WHERE jobtableid = " + row.Cells[5].FormattedValue.ToString(); cmd.CommandText = "UPDATE dbo.JobStatus SET ShipMethodTransmitted = '" + row.Cells[8].FormattedValue.ToString() + "' WHERE jobtableid = " + row.Cells[5].FormattedValue.ToString(); cmd.CommandText = "UPDATE dbo.JobStatus SET DateShipTransmitProcessed = '" + row.Cells[9].FormattedValue.ToString() + "' WHERE jobtableid = " + row.Cells[5].FormattedValue.ToString(); cmd.CommandText = "UPDATE dbo.JobStatus SET ShipmentProcessedBy = '" + row.Cells[10].FormattedValue.ToString() + "' WHERE jobtableid = " + row.Cells[5].FormattedValue.ToString(); cmd.CommandText = "UPDATE dbo.JobStatus SET Critical = '" + row.Cells[11].FormattedValue.ToString() + "' WHERE jobtableid = " + row.Cells[5].FormattedValue.ToString(); cmd.CommandText = "UPDATE dbo.JobStatus SET ShipTransmitStatus = '" + row.Cells[13].FormattedValue.ToString() + "' WHERE jobtableid = " + row.Cells[5].FormattedValue.ToString(); cmd.Connection = sqlConnection1; sqlConnection1.Open(); cmd.ExecuteNonQuery(); sqlConnection1.Close(); } catch (Exception e) { MessageBox.Show("Update Failed!!!"); } } } </code></pre> <p>Can anyone tell me what is wrong with these statements? Thanks!</p>

    1. COThat code will only update ShipTranmitStatus; because you are replacing the CommandText on each line with new CommandText. You can update all the fields in 1 UPDATE statement instead of 6 separate ones. Also you should use SQLParameters to supply the values to your Command.

    2. COAlso, are row.Cells[5].FormattedValue.ToString() column names? if not, they will need to be wrapped in single quotes like the first block was.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
