How in VB.net we can encode string for SQL

Question

For example, in sql

all ` should be replaced with `` right?

Well, is there a function built in by vb.net that does that sort of thing already?

That way I do not have to encode it.

By the way, I do not access sql database directly. Basically I am creating a text file and that text file contains raw sql statements. Most of the answers deal with accessing sql data directly.

I don't think so as I think the only case where something like this would be relevant is if you were doing inline SQL Commands without parameters.

This has a risk of SQL Injection, and therefore you should create commands like this:

Dim cmd As New SqlCommand("UPDATE [TableA] SET ColumnA=@ColumnA WHERE ID=@ID", Conn)
cmd.Parameters.Add("@ColumnA", SqlDbType.NVarChar).Value = txtColumnA.Text
cmd.Parameters.Add("@ID", SqlDbType.Int).Value = ID
cmd.ExecuteNonQuery()
