Problem with Excel to SQL Import

I have attached code that reads a row at a time from an excel spreadsheet and writes it to a SQL table, checking wheater the record first exists in the table before writing. I am getting an error .

The SQL table has the first column set as an autoincrementing identity field. I am not writing to that field. Only the fields after it.
The error is occurring near the bottom of the code on the line:  cmd.ExecuteNonQuery().
Error is :  The name "Hispanic" is not permitted in this context. Valid expressions are constants, constant expressions, and (in some contexts) variables. Column names are not permitted.

Any help would be appreciated.

See code......

Write your SQL out to the console or to a message box. Let's see wha the string looks like.

HoggZillaCommented:
Based on what I see, you need the inserted values in single quotes.

I corrected the quotes but getting syntax error. Can you take a look ?
cmd.CommandText = ("INSERT INTO [Test] (JPSID, Ethnicity, MaleFemale, " & _
 "Race, DOB, SubjectName, FirstName, MiddleName, LastName, Suffix, Address1, Address2, " & _
 "City, Zip, HomePhone, CellPhone, WorkPhone, RelativePhone, EMailAddress, Verify") & _
                    " VALUES('" & CurrWS.Cells(i, "A").Value & "','" & CurrWS.Cells(i, "B").Value & "', '" & _

What error are you receiving. Can you print or display the SQL statement before it tries to execute. Let's see what is trying to run.

wsenterAuthor Commented:
I tried to use debug.print(cmd.CommandText.ToString)  No work.

Can you suggest how to ?

HoggZillaCommented:
Put the commandText into a variable and write the variable to a message box.

IUFITSCommented:
I would consider using a parameterized statement if I were you for mulitple reasons.  First, it will handle the quotes for you.  Second, it will help minimize the risk of anyone either using SQL injection techniques or simply messing the query up because of the text they include in the spreadsheet.  An added bonus is that you can prepare it and the SQL Server will cache your execution plan so it may run faster the next time you run it.  Even if you don't accept this answer, I highly recommend you do it.  :)   Further, you can reuse that command and just change the values of the parameters which is handy if you're doing a loop inserting statements for example, you don't have to rebuild the SQL each time.
I'll include a basic example that sets one up and then you can see it executes like you normally would:
 
 


Dim sql As String = "Select * From MyTableName " & _
		" Inner Join SecondTable On SecondTable.Guid = MyTableName.Id " & _
		"        Where Id = @Id And LastName = @LastName"
 
Dim cmd As New SqlCommand(sql, _connection)
cmd.Parameters.Add("@Id", SqlDbType.Int, 4)
cmd.Parameters.Add("@LastName", SqlDbType.VarChar, 20)
 
cmd.Prepare()
 
cmd.Parameters("@Id").Value = Id
cmd.Parameters("@LastName").Value = "Smith"
 
Dim dr As SqlDataReader = cmd.ExecuteReader

"Put the commandText into a variable and write the variable to a message box. "

It never would work because the error was generated within the SQL statement itself. I figured it out and fixed it myself but thanks for your input.
