I need to query a number field from a table, and the value to query, is comming from a BuildRowsetFromString. Whenever I try to query, I get this error:

Failed to convert parameter value from a String to a Int32. Input string was not in a correct format.

How can I convert the string BuildRowsetFromString generates, to a number?

    Please can you provide an example of how you are using BuildRowsetFromString()? – Eliot Harper Sep 6 '16 at 2:47

I don't think so AmpScript can covert string to int. You have to use SSJS with a combination of AmpScript to convert string to int.

Also, use JavaScript parseInt function in SSJS like below.

SET @FirstNumber = "10"

    <script runat=server>


    var firstNumber = Variable.GetValue("@FirstNumber");
    var secondNumber = 10;
    var add = secondNumber+parseInt(firstNumber);



Output: 20


The returned result is of type String, try to parse by using integer.valueof(s); and check before if it's different from NULL.

  • I get this error: The function call uses an unrecognized function name. Function Name: integer.valueof – Paulo Manrique Sep 5 '16 at 15:26
