Hi,
Please help me with the best way to change the datatype of a column in a
all tables in DB from bigint to varchar. Please consider the following
facts.
1) Do not cross post to multiple lists.
2) What is the purpose behind this change?
* DB Size - 75 TB
* Number of tables - ~100
* Some tables are partitioned and some are not partitioned.
* All partitioned tables are big in size.
* For reference, the largest partition size is 4 TB, similarly the
size of 10-12 partitions ranges between 1 to 4 TB.
* We have indexes and FK on tables.
* Physical Replication is configured with 2 standby DBs.
