Update of /cvs-repository/Products/DCOracle2
In directory cvs.zope.org:/tmp/cvs-serv29767
NULL column handling fixes for problems reported by Christopher Jenkins.
dco2 will keep datatypes on Nulls for rebinds, instead of snaping to SQLT_STR.
DCOracle2 scans columns on executemany() to determine to reprepare the statement
and get the a non-None value for making a type determination.
=== Products/DCOracle2/CHANGELOG 1.35 => 1.36 ===
o Changed ZOracleDA to promote OracleDate objects to DateTime
objects in Zope (based on string representation).
+ o Fixed some NULL handling bugs reported by Chistopher Jenkins
+ which showed up with date ops -- a subsequent BIND (rexecuting
+ a previously prepared statement) with a None/NULL would have
+ been bound to a string type (dty 5) now will preserve prior dty.
+ Also, DCOracle2 executemany() scans for NULL columns and forces
+ reprepares when a column contains all NULLs to flush out cached
+ bind types (and sets the statement for a reprepare NEXT time
+ through as well since the NULLs will snap to dty 5 on prepare,
+ which is wrong when the real type comes around). Also skips
+ None for type determination.
