正在做一個(gè)獵頭系統(tǒng),今天遇到了一個(gè)問題,異常信息如下:

在網(wǎng)上查了一下原來是驅(qū)動(dòng)的問題,網(wǎng)友給了說明和解決方案:
（1）如果你采用jdbc-odbc驅(qū)動(dòng)。那么只能告訴你，你必須按照查詢的順序去獲取順序的字段。如果打亂順序，或重復(fù)查詢同一列，將會(huì)獲取null或拋出上面的異常。
（2）如果你采用weblogic jdriver驅(qū)動(dòng)。那么將不支持jdbc2.0 method。
（3）如果你采用MS自己的JDBC驅(qū)動(dòng)。那么在查詢語(yǔ)句中不包含blob或clob字段（就是Image和Text類型）的時(shí)候，查詢是支持re-read方式的，可以非順序查詢。但是一旦包含的blob或clob字段。那么就必須按照順序查詢，且不支持重復(fù)查詢。
解決這個(gè)問題建議換個(gè)功能全點(diǎn)的驅(qū)動(dòng)，要不就不要用blob或clob類型的字段。
