使用AND逻辑而非OR的多值参数

Question

My report uses a multi-value parameter string to search through a block of text. We want the ability to only return results that meet all the values entered for this string. For example: Only return rows that have "Biopsy", "Prostate", AND "Lateral" values.

How can I accomplish this?

I'm not sure if crystal report accepts that condition (REGEXP_LIKE). Btw... You have to send the parameters one by one, for example:

Dim p As New Report
p.parameter1 = txtParameter1.Text
p.parameter2 = txtParameter2.Text
p.parameter3 = txtParameter3.Text
p.show()

Then in report

Public parameter1 As String
Public parameter2 As String
Public parameter3 As String

If String.IsNullOrWhiteSpace(parameter1) Then
    "report-object".SetParameterValue("Parameter in Query", "'%'")
Else
    "report-object".SetParameterValue("Parameter in Query", "'" + parameter1 + "%'")
End If
.
.

I usually use this code for that.. and well in your command object, you only need a simple AND to match the parameters.
