Good evening people.

I'm trying to create a simple table via MySQl Navigator.
The table il structured in this way

dt_amt  Date            Not Null        Primary Key
oper    INT             Not Null        Primary Key
amount  Decimal(3,3)    Null            ---

but when I choose "fire" it shows me a "multiple primary key defined"
message and doesn't make me create the table.

Isn't MySql able to handle multiple primary key or it's a navigator bug?

You cannot define multiple primary keys using PRIMARY KEY. The name of a PRIMARY KEY is PRIMARY, and you'd end up with two indexes having the same name.

To work around this, use a UNIQUE index instead for one of them.

In the same day I can receive data from different operators.

Thanks in advance D.
