DB2 SQL Code

The problem with DB2 SQL Code 

One can get this issue of DB2 SQL Code while connecting their database in docker with other configurations. The code for the connection is:

type = "db2"


url = "jdbc:db2://localhost:50000/AMDB"


username = <username>


password = <password>

While running the above code one can get the following error:

Solution

A database connection is a work session that a program opens to connect to a particular database server and execute SQL statements as a particular user. 

An SQL Developer object called a database connection defines the details required to connect to a certain database as a particular user. To use SQL Developer, you must have at least one database connection—either an existing one or one you’ve built or imported.

One of the major reasons behind this error is that the object is not specified in the database as per SQL0204N.
Since it’s not a system object, this UM DIALECT user table. The view is probably used by your client tool, but the database doesn’t have it. 

Another reason can be that before starting any of the WSO2 Identity-server tools if you are configuring the WSO2 Identity Server, you must generate its metadata tables.

One of the above reasons can act as a major issue for the above error in your case as well.
