[Qgis-user] manually change FID/OID

[José Pedro Santos]

I don't understand exactly why you want to change the ID number but be careful doing that, like Stefano said and correctly, you can corrupt the all table.

Maybe I misunderstood what are you trying to do, just be aware that manually modifying FID or OID in a shapefile or geoDb feature class is likely to corrupt them.

Hi,



no, i want to do it the other way arround. the problem is that i want to change the FID value, which is generated by arcgis or qgis automatically (the grey numbers in the first column). i have already a column with id values. i want to assign the FID/OID with their values.

Hi Christian,



Why you don't create a new column with the ID values that you want? If

you want to edit some columns or rows you can use the Field Calculator.

Hi,



i have the following problem: If i export a postgis db with qgis it

mixes up the rows. On the first position in the attribute table is a

value with id 2400 but should be 0 or 1

e.g.

       id      objectname

0 | 2400 | name 2400  ...

1 | 828   | name 828   ...



When i inspect the database, everything seems to be ok, as the line with

id =1 shows up on the top position and id is set as primary key.

Has anybody an idea how i can get my table back in the right order or

how to manually update the FID/OID with my id values?



I need that for an geotools importer which reads the FID and i cant

change the import parameters.



Thanks christian
