Problem When we add default constraint on a field it is automatically assigned a name in following format Format: DF__tablename__PARTOFFIELDNAME__HASHCODE Example: DF__scheduled__CREAT__00DF2177 DF__scheduled__MODIF__01D345B0Format: DF__tablename__PARTOFFIELDNAME__HASHCODE Example: DF__scheduled__CREAT__00DF2177 DF__scheduled__MODIF__01D345B0 HashCode part of the format is different on each database so we can’t just find the name of constraint and use that in our alter script. That’s when …
