使用jdbc接口PreparedStatement.executeBatch()向oracle中批量执行sql时候,出现异常ArrayIndexOutOfBoundsException,具体信息如下:

java.lang.ArrayIndexOutOfBoundsException: -32413
    at oracle.jdbc.driver.OraclePreparedStatement.setupBindBuffers(OraclePreparedStatement.java:2672)
    atoracle.jdbc.driver.OraclePreparedStatement.executeBatch(OraclePreparedStatement.java:10688)
    atcom.keyi.xxx.dal.xx.importFile(PublicCustomerImportDao.java:107)


看样子是oralcejdbc驱动内部setupBindBuffers方法中出现了数组越界异常,但是是什么原因导致的此异常出现,一直没有搞清楚。在网上找到一个帖子,通过他的思路得到了解决方案。


帖子内容如下:


The 10g driver apparently keeps a global serialnumber for all parameters in the entire batch, with a "short"variable. So you can have at most 32768 parameters in the batch. I was havingthe same exception because I have a INSERT statement with 42 parameters and mybatches can be as big as 1000 records, so 42000 > 32768 and this overflowsto a negative index. I reduced the batch factor to 100 to be safe, and all iswell. I guess your update DML should have a larger number of parameters perrecord, right? (My diagnostic of the bug is just deduction from the symptoms)

大体的意思是,oracle的preparedStatement批量执行sql时,对参数个数是有上限的(针对不同版本的oracle驱动,这个上限对不同的可能是不同的),这个参数个数的含义指addBatch的次数*每条sql中的参数个数。对于Oracle 10g的驱动来说,这个值可能是32768,所以编程时,addBatch的次数*每条sql中的参数个数应该小于这个值,否则报错。


按照这个思路,将addBatch的数量减少,使每次executeBatch的参数值小于32768,发现异常解决。
