问题描述
我已经将一些数据从模式 A(表 x)导出到 XML，我正在读取 XML 并将数据插入到模式 B(表 y)中.在 20000 条记录之后插入数据时，它说
I have exported some data from schema A (table x)to XML and I am reading the XML and inserting the data into schema B(table y). while inserting the data after 20000 records it says
com.ibm.db2.jcc.am.SqlSyntaxErrorException: [jcc][t4][20111][11366][3.63.75] The value of a host variable is too large for its corresponding use. Host variable=1. ERRORCODE=-4461, SQLSTATE=42815
com.ibm.db2.jcc.am.BatchUpdateException: [jcc][t4][102][10040][3.63.75] Batch failure.
该批次已提交，但该批次的单个成员至少发生了一次异常.
The batch was submitted, but at least one exception occurred on an individual member of the batch.
我比较了表 x 和表 y 中对应列的数据类型，它们是相同的.源和目标中的标识(自动增量)col 和 LONG VARCHAR 都是 BIGINT..
I compared the data types of the corresponding columns in table x and table y they are the same. It is BIGINT for the identity(Auto increment) col and LONG VARCHAR in both source and destination..
请帮助解决此问题.
推荐答案
我曾经遇到过类似的问题.我解决了将队列大小添加到 XML 中的问题.在我的情况下是这样的:
I had a similar problem one time. I solved it adding to the XML the queue size. In my case was something like this:
<task>
<name>Ventas MCC</name>
<queueSize>100</queueSize>
<queueNames>trashQueue</queueNames>
<queryTasks>
<queryTask>...</queryTask>
</queryTasks>
</task>
使用 queueSize 批量启动查询.
With the queueSize the queries was launched in batch.
