Re: [EXTERNAL] database "diff"

Hola Paul,

I wrote a set of utilities to work with databases, including one to compare .db files (dbdiff.py). I still consider them work in progress from the documentation point of view. You are welcome to use them. You can customize diff_filter() to deal with expected differences between databases generated by different tools. We had that problem when moving from capfast to tdct (where '.NPP' was converted to 'NPP', for instance).

Hi Paul,

 

I have attached a simple perl file which sorts db records. To compare two db files, sort one and redirect output file file1 then sort the other and redirect to file2. Then compare file1 to file2. The perl script also reports (via STDERR) duplicate records, carriage returns and unprintable characters that it finds.

 

Extension is .txt to satisfy outlook.

Subject: [EXTERNAL] database "diff"

 

We're converting our (~200) databases from gdct to vdct.  After we drag around the records in vdct to visually arrange the linked records, we want to perform a final check to compare the original and the vdct records. We plan to write a text processing program/script to do this,  but...

 

Has anyone made a tool to compare the records and their fields in two database files?  Is there a utility (in the IOC) to dump a database report that we can compare (before/after)?  Does the old dbreport extension provide reports that list a record's field information that we can compare?

 

 

We're doing this because gdct doesn't run on Linux (right?).

 

Thanks,
