<p>我用你的测试数据,进行测试,脚本如下,加载没有问题:</p><p></p><p>LOAD TABLE d_tax_kind<br/>(</p><p>TAX_KIND_KEY '|',<br/>TAX_KIND_CODE '|',<br/>TAX_KIND_NAME '|',<br/>TAX_ITEM_CODE '|',<br/>TAX_ITEM_NAME '|',<br/>TAX_FLAG&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; '|',<br/>EFFECTIVE_DATE '|' null(''),<br/>END_DATE&nbsp;&nbsp;&nbsp; '\x0d\x0a' null('')<br/>)<br/>FROM 'c:\d_tax_kind.out' <br/>ESCAPES OFF<br/>QUOTES Off <br/>format ASCII<br/>WITH CHECKPOINT ON;</p><p><font color="#f73809">需要注意的问题:</font></p><p><font color="#f73809">ASCII变长数据加载时,字段分割符号和行分隔符一般需要描述,</font></p><p><font color="#f73809">你的脚本重复描述了字段分隔符,没有描述行分隔符。</font></p><p></p><p></p>
