SQL DELETE statement syntax

问题

Trying to execute a delete query and getting the following error

Syntax error (missing operator) in query expression 'cname VALUES @cname'.

code

Dim conn As OleDbConnection = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & My.Settings.strFileName)
conn.Open()
Dim cmdText = "DELETE FROM products WHERE cname VALUES @cname"
Dim cmd As OleDbCommand = New OleDbCommand(cmdText, conn)
With cmd.Parameters
  .Add(New OleDbParameter("@cname", DataGridView1.Item("cname", i).Value))
End With
Dim dt As New DataTable("products")
cmd.ExecuteNonQuery()
conn.Close()
conn = Nothing

回答1:

The way you wrote your delete statement is not correct.

You should write it like this:

Dim cmdText = "DELETE FROM products WHERE cname = @cname"

回答2:

You need an operator

DELETE FROM products WHERE cname = @cname

回答3:

And to delete all record from a table with a specific ID, you just have to;

deleteMore:
DELETE TOP(100) TableName WHERE toDelete='17'
IF @@ROWCOUNT != 0
    goto deleteMore:

This will delete the first 100 records, and repeatedly until all records with 17 are gone.
