[gdal-dev] shapefile field size

[Clay, Bruce]

Follow on to earlier message.

 

I removed the SetLength and SetPrecision from the field specification
and things are working now.  ArcMap thinks the integer fields are
Doubles with length of 11 and precision of 11 but the values do not
appear to be truncated so that is a good thing

 

It just seems odd that the OCI driver accepted the size but the
shapefile driver did not.

Subject: [gdal-dev] shapefile field size

 

I have an OGR based application that I am having problems with data
storage

 

Several fields are OFTInteger and several are OFTReal

 

When I write a dataset using the OCI driver the integer fields all store
valid information.

 

When I write a dataset using the Shapefile driver the integer fields
appear to be truncated to shorts. They are defined with a field width of
4 bytes.  It almost looks like the data is stored as ASCII because only
the 4 most significant digits are actually saved in the shapefile.

 

Is this the intended operation or is there some extra flag that I need
to set when I switch between creating an Oracle table and a shapefile?
