Question

I’m using Classic ASP/MySQL to insert a long user input in to my database, generated from a rich text editor. The column is set to LONG-TEXT.

Being new to parameterized queries (prepared statements), I am not sure of the data length to use for this particular query.

This is my ‘Add Parameter’ statement for a simple VARCHAR query:

Const ad_varChar = 200
Const ad_ParamInput = 1

Set newParameter = cmdConn.CreateParameter("@firstName", ad_varChar, ad_ParamInput, 50, firstName)
cmdConn.Parameters.Append newParameter

As you can see, I used the value 50 for the data length. What do I use for a long-text column, where the users data length is unknown? It could be 50, or it could be 8000!

Answer 1

Use length of itself?

Set newParameter = cmdConn.CreateParameter("@firstName", ad_varChar, ad_ParamInput, Len(firstName), firstName)
