I have something weird in DBD::Oracle (1.44 and 1.74)
Client = 10.2.0.1.0 / AIX-5.3 - Server = 11.2.0.3.0 - 64bit / Linux
consider a field that looks like this:
{ LINK = undef,
NAME = 'D_GELD',
NAME_lc = 'd_geld',
NAME_uc = 'D_GELD',
NULLABLE = '',
PRECISION= 8,
SCALE= 0,
TYPE = 3,
TYPE_NAME= 'DECIMAL',
dbd_type = undef,
ora_est_row_width = undef,
ora_fail_over= undef,
ora_lengths = 172,
ora_rowid= undef,
ora_type = undef,
ora_types= 2
}
*sometimes* I get 126 in the PRECISION entry instead of 8
does that ring any bells?
I get 126 only if I use a where clause that addresses a field that is
first in an index on that table otherwise I get 8
I can reproduce it with this:
