本文介绍了Oracle数据库中ORA-01002 fetchoutofsequence错误的原因及解决方法。该错误通常发生在尝试从活动集获取数据时未成功执行解析和执行调用的情况下。文章提供了通过调整程序代码来避免此错误的具体步骤。

ORA-01002 fetch out of sequence

Cause In a host language program, a FETCH call was issued out of sequence. A successful parse-and-execute call must be issued before a fetch. This can occur if an attempt was made to FETCH from an active set after all records have been fetched. This may be caused by fetching from a SELECT FOR UPDATE cursor after a commit. A PL/SQL cursor loop implicitly does fetches and may also cause this error.
Action Parse and execute a SQL statement before attempting to fetch the data.

程序代码里面

在conn = ConnectionHelper.getDefaultConnection();后加
conn.setAutoCommit(false);
