Hi Experts,

 

 Environment: Using PowerBuilder 2022 Build 1900 (SQL Server 2019)

 I am coding a smart search (but stuck) on a data window filter:

 I have a window with top simple search datawindow (just like single line edit where i am entering the text) and bottom portion i have a results grid datawindow (displaying the results).

 The bottom results datawindow displays columns like → Name, File Number, Location, etc...

  I want to enter search like any special character (~, `, !, @, #, $ etc) and display results that match any of the columns with any matched characters.

  I have trouble filtering single quotes and double quotes (rest all special characters are working fine).

  ► I want to keep building the expression: ◄

   ls_searchtext = entered a single quote 

  ►/*filter by name */

   ls_Filter = "( lower(name) like '"+ ls_searchtext +"'" + ")"

   li_Filter = dw_results.Filter()

   ls_current_filter = dw_results.object.datawindow.table.filter 

  ►/*filter by file number*/ 

    ls_Filter = ls_current_filter + " OR ( "  +  "lower(file_number) like '"+ ls_searchtext +"'" + " )"

   li_Filter = dw_results.Filter()

  ►/*filter by location*/ 

     ls_current_filter = dw_results.object.datawindow.table.filter
     ls_Filter = ls_current_filter + " OR ( " + "lower(location) like '"+ ls_searchtext +"'" + " )"

     li_Filter = dw_results.Filter()

 ► more columns.

    The issue is with using single quotes and double quotes i get error message → "Missing close paranthesis"

    how do i search in any of the columns value with a single quote or double quotes using filter expression.

    For example → I want to search for a word called → "it's" and filter results that matches → "it's" or could be a name like "Mc' Arthur"

   What is the additional escape characters that i have to use for single quotes or double quotes while filtering results (i have tried ~~~' and other   combinations like \'  but no luck). Is there any other smarter way to do this or code examples.

    Any help greatly appreciated.

 

 Thanks in Advance

 Suresh
