ASP/MySQL - Parameterized Query(s) - mysql

Question

In my example code below, you can see that I have been trying to suss-out parameterized queries in ASP and MySQL.
I am doing something wrong here and would like to know what it is. In my example, you can see two queries. If I leave off the last query (under the '//////// line), this script works. As soon as I add the last query, I get the following error:
"Multiple-step OLE DB operation generated errors. Check each OLE DB
status value, if available. No work was done."
I'm really not sure what I am doing wrong. I googled the error and it said something about data types but it didn't register in my empty head!
Am I declaring the parameters (.createParameter) in the right place, as I'm processing multiple queries? Do they have to be declared before all the queries?
My Code
Set connContent = Server.CreateObject("ADODB.Connection")
connContent.ConnectionString="...blah..blah..blah..."
connContent.Open
Set cmdContent = Server.CreateObject("ADODB.Command")
Set cmdContent.ActiveConnection = connContent
cmdContent.Prepared = True
Const ad_varChar = 200
Const ad_ParamInput = 1
Const ad_Integer = 3
Const ad_DBDate = 133
Const ad_DBTimeStamp = 135
theNumber = 23
theText = "Hello there!"
theDate = "2011-10-15"
SQL = " INSERT INTO testTable (integerCol) VALUES (?); "
Set newParameter = cmdContent.CreateParameter("#theNumber", ad_Integer, ad_ParamInput, 50, theNumber)
cmdContent.Parameters.Append newParameter
cmdContent.CommandText = SQL
cmdContent.Execute
' ////////////
SQL = " INSERT INTO testTable (varCharCol) VALUES (?); "
Set newParameter = cmdContent.CreateParameter("#theText", ad_varChar, ad_ParamInput, 50, theText)
cmdContent.Parameters.Append newParameter
cmdContent.CommandText = SQL
cmdContent.Execute
UPDATE:
Well I got both queries to work but I had to set another command object and active connection, shown below. Although it works, is this the right thing to do with my type of connection? Do I need to set the command object to nothing after each query then?
' ////////////
Set cmdContent = Server.CreateObject("ADODB.Command")
Set cmdContent.ActiveConnection = connContent
SQL = " INSERT INTO testTable (varCharCol) VALUES (?); "
Set newParameter = cmdContent.CreateParameter("#theText", ad_varChar, ad_ParamInput, 50, theText)
cmdContent.Parameters.Append newParameter
cmdContent.CommandText = SQL
cmdContent.Execute

Answer 1

I believe your problem is because both insert statements are using the same command object. Because of that, the second command will have both parameters in it and that is what I believe causes the exception you are seeing.
To fix the problem, add:
Set cmdContent = Server.CreateObject("ADODB.Command")
Set cmdContent.ActiveConnection = connContent
after your //// comment and things should start working.
