Next, implement a Data App (Python script) to read data from Db2 and e.g. write that data into tables in the data warehouse. Example:

import ibm_db

try:
    conn = ibm_db.connect(
        "DATABASE=SAMPLE;"
        "HOSTNAME=1.2.3.4;"
        "PORT=448;"
        "PROTOCOL=SOCKETS;"
        "UID=APLPELIQAN;"
        f"PWD={pq.get_secret('IBM Db2 Password')};",
    )

    st.success("Connected to IBM Dd2 successfully!")

    sql = "SELECT * FROM MYTABLE FETCH FIRST 10 ROWS ONLY"

    stmt = ibm_db.exec_immediate(conn, sql)

    rows = []

    result = ibm_db.fetch_assoc(stmt)
    while result:
        rows.append(result)
        result = ibm_db.fetch_assoc(stmt)

    st.write(rows)

    ibm_db.close(conn)

except Exception as e:
    st.error(f"Connection failed: {str(e)}")
