Question

Using a SELECT statement I query a database and get back a result in the format: name1,name2,name3

Depending on the database entry this result could have any number of names: name1,name2…name(n)

I would like to use this data to query another database like so:

SELECT Name, SerialNo, Model FROM InstrumentTable where ID=1 and InstName IN name1,name2,name3

In order to do this I need to convert name1,name2,name3 to (‘name1′,’name2′,’name3’)

I have tried splitting the String into an array of Strings

    Dim ref1s As String = cmdf1.ExecuteScalar()
    Dim fields() As String = Nothing
    fields = ref1s.Split(",")

and then concatenating them in an array

For i As Integer = 0 To fields.Count - 1
     MsgBox(String.Concat("'", fields(i), "'"))
 Next

but I haven’t been able to figure out how to do it yet.

Adding the brackets at the start and end of the string shouldn’t be a problem just adding the quotes to each name and separating them with a comma is the issue.

Can anyone help me with this?

Answer 1

You got a bit previous

For i As Integer = 0 To fields.Count - 1
  fields[i] = String.Concat("'",fields[i],"'")
Next

Then

strValue = fields.Join(',')
