    Updating part of a column

    NeptuneTG
      I have a column in a SQL database which contains data (numbers separated by a pipe sign ex: 23|2|5) and I want to write something that will update the second number which in this case, 23|2|5, it would be 2. Can someone help me out on this?

          How about something like this:

          1) Retrieve records using query
          2) Either replace the middle value using list functions:
          #ListFirst(myColumn, "|")#|#newValue#|#ListLast(myColumn, "|")#

          or use regular expressions:
          #ReReplace(myColumn, "([0-9]*)[|]([0-9]*)[|]([0-9]*)", "/1|#myValue#|/3")#

          3) Insert value back into database

          Depending on your database, you may even be able to work your regular expression statement into your SQL.

            Normalize your database and then you can simply update the record you want.

                I finally acheived what I needed to but not by taking Dan's advice.

                Thanks Dan for your advice, but what is one to do if they are in a situation where they are working with a vendors' database and do not have the luxury to normalize their database? ( which is where I have found myself)


                Here is an example of the field i'm trying to update: LAYOUT=BOTTOM|70|30,TOP=,LEFT= 13|4|2|3|22,RIGHT=14|1|10]
                (My goal is to insert a |23 between the 13|4)

                Solution:
                <cfquery name="Rs" datasource="FusionDox">
                SELECT *
                FROM dbo.FDOX_USERINFO
                </cfquery>

                </head>

                <body>
                <cfoutput query="Rs">
                <!--- finds the postion in the string--->
                <cfset variables.pos = FIND("LEFT=13|", rs.PluginSelections, 1)> <!---the 1 is the starting position--->

                <!---once you found it load left side into myvar1 and will count 7 characters past the first position--->
                <cfset variables.myvar1 =#MID(rs.PluginSelections, 1, variables.pos + 7)#>

                <!---once you found it load right side into myvar1 and will count 7 characters past the first position--->
                <cfset variables.myvar2 = #MID(rs.pluginselections, variables.pos + 8, LEN(rs.pluginselections) - variables.pos)#>

                <!---once you have the left and the right counted apart then you just plug in the myvar3 variable--->

                <cfset variables.myvar3 = variables.myvar1 & "23|" & variables.myvar2 >

                #rs.pluginselections#  |   #variables.pos# <br />
                1: #variables.myvar1# <br />
                2: #variables.myvar2# <br />
                <b>3: #variables.myvar3#</b>
                <br />

                <cfset variables.myvar4 = Replace(rs.pluginselections, "|||", "|", "ALL")>

                <span class="style1"><strong>4: #myvar4#<br />
                </strong>
                <br />
                </span>
                <!---ONLY RUN THIS ONCE OR THE UPDATE WILL RUN THE UPDATE AGAIN--->
                <!---<cfquery name="Rs2" datasource="FusionDox">
                UPDATE FDOX_UserInfo
                set FDOX_UserInfo.PluginSelections = '#myvar3#'
                WHERE FDOX_UserInfo.userid = #rs.userid#
                </cfquery>--->
                </cfoutput>
