Summary0003521: Create Table First is creating table with all columns as primary key instead of none
DescriptionIn the case of source_node_database_tables do not have any primary keys and some fields of the source_node_database_tables are empty, target_node_database_tables are created successfully when initial load firstly, but Symmetric can not insert automatically values into target_node_database_tables.

part of target_node symmetric.log:

Steps To Reproducesource node:
1.Oracle database type
2.Tables of needing to synchronzie do not have any primary keys and some fields of the tables are empty in the oracle database

target node:
1.MariaDB/MySQL database type the MariaDB/MySQL database, it has not the source_node_database_tables of needing to synchronzie


has duplicate 0003529 closed Symmetric needs to insert successfully null value into target_node_database_tables when initial load firstly

You tried to sync a null value to the "id" column, which is defined as not nullable, so the database rejects the row. What did you expect to happen?

Thanks for the quick response!

In the case of source tables(need to sync) do not have any primary keys and some columns are null, I want to sync a null value to the "id" column or other column,which is defined as nullable, can you reach it?

In the case, I know that symmetric will create primary key for each filed of target tables when the symmetric create target table .

Will change the default behavior in 3.10.

If a table does not have a PK SymmetricDS will try to create a target table with all columns used in the PK. This allows
loads to run multiple times without duplicate data. The first time would insert, additional runs would fall back to updates and
since the target has a PK now it will not duplicate. In your case though you have tables with too large of columns to use all cols
in PK. You can set the following parameter to create the target without PKs as the source. However you will need to use the delete first
on the table reload request to ensure every time data is loaded into the target it is deleted or truncated so that duplicates to not occur.

Make this the default going forward:
