PutDatabaseRecord processor error: "Record does not have a value for the PrimaryKey column 'HOST' "

[#1]

Hi,

I am getting error "Record does not have a value for the PrimaryKey column 'HOST' " when I update a data in source db table. This issue is happening when destination DB table's name: 'user' or 'users'. It is working fine when destination table's name is change to 'report_user'

(I mean when we change the table name 'user'or 'users' to something else which is not used as mysql internal  table)

 I am not sure why it is trying to insert or update on internal mysql table as I am giving the destination DBName and tableName.

Can anyone suggest how can we fix this issue without changing the destination table name?

Seems like it's not using the schema name field when building the insert statement.   Are you specifying the database to use in your DBCP connection pool service?  

Although user/users are reserved words in mysql, so I would expect problems with that name.   Possibly creating the table wrapping the name in back ticks might work.

Are you specifying the database to use in your DBCP connection pool service?  -> yes

I solve this issue. I have given Catalog Name : destinationDBName and Make empty schema Name value in putdatabase  record processor. Now I am able to perform insert , update and delete action source to destination 'user' table.

Thanks,
