3285975 - UPDATE of a bit columns for an existing DOL table returns wrong result - SAP ASE

• UPDATE of a bit column for an existing DOL table returns wrong result.

• For example, if you run the following SQL on the MYTABLE table with two columns BITCOL1 and BITCOL2 defined as BIT datatype and not nullable:
  
  

  select * from MYTABLE where MYID = 2000000000017224
  go
  update MYTABLE set BITCOL1 = 1, BITCOL2=0 where MYID = 2000000000017224
  go
  select * from MYTABLE where MYID = 2000000000017224 and BITCOL1 = 1 and BITCOL2=0
  go 

  the UPDATE query says (1 row affected), but no row qualifies the next SELECT query.
