PeopleCode to AutoIncrement an AlphaNumeric Transaction Number

I have code to auto-increment an alphanumeric field, using SQL calls. It is specific to a 4-character field, but can easily be adapted to different length fields.

SQLExec("SELECT decode(substr(oldvalue,2,3),'ZZZ', TRANSLATE(UPPER(SUBSTR(oldvalue,1,1)),'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ', '123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ0'),substr(oldvalue,1,1)) ||decode(substr(oldvalue,3,2),'ZZ',TRANSLATE(UPPER(SUBSTR(oldvalue,2,1)), '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ', '123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ0'),substr(oldvalue,2,1))||decode(substr(oldvalue,4,1),'Z', TRANSLATE(UPPER(SUBSTR(oldvalue,3,1)), '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ', '123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ0'),substr(oldvalue,3,1))||TRANSLATE(UPPER(SUBSTR(oldvalue,4,1)), '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ', '123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ0') FROM dual, (select :1 as oldvalue from dual)", &priorvalue, &newvalue);
If &newvalue = "0000" Then
   &bOverrun_Error = True;
End-If;

Re: PeopleCode to AutoIncrement an AlphaNumeric

Larry as your SQL works fine I'm just curious on what kind of requirement derived such code. I find it odd to increment an alpha numeric character :) - none the less, your SQL works perfect.

Re: AutoIncrement an AlphaNumeric Transaction Number

Have an alphanumeric field, ACTIVITY_ID. Was given requirements to create a Mass Add page, allowing user to auto-generate a large number of Project_Activity rows given a starting point within an alphanumeric range, along with the # of new rows desired, along with other common field values. Tried to get user to agree to only numeric incrementing, but they insisted upon alphanumeric. Go figure.

Re: PeopleCode to AutoIncrement an AlphaNumeric Transaction Num

In Inventory the MSR no gets generated automatically.
Could that PeopleCode logic will also work for your requirement?
