db2 ? SQL1024
SQL1024N A database connection does not exist.
Explanation:
There is no connection to a database. Other SQL statements cannot be
processed unless an SQL CONNECT was previously executed.
The command cannot be processed.
User response:
If the error occurred when disconnecting from the database, continue
processing. If the error occurred on another SQL statement, issue an SQL
CONNECT statement and resubmit the command or statement.
sqlcode: -1024
sqlstate: 08003
说得很清楚了，没有数据库连接，在查询或者进行数据库操作前，必须先连接到需要操作的数据库
