Sql server 2008 - 用于插入大量数据的性能调整功能(Sql server 2008 - performance tuning features for insert large amount of data)

我必须将大量数据插入表中。 sqlserver 2008(与2005相比)是否有任何新功能可以在这种情况下提高性能?

对样式表进行一些更改后,它将执行以下操作:

因为每个SubLevel输出中应该有一行, SubLevel首先迭代到SubLevel。 使用ancestor::LevelSubLevel访问其他信息。 尝试:

<xsl:stylesheet version="1.0" 
                  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
                   >
    <xsl:output method="text" omit-xml-declaration="yes" indent="no"/>
    <xsl:template match="/">
      <xsl:text>PayReceive,CommodityName,StartDate,ClientPV</xsl:text>
      <xsl:text>&#xA;</xsl:text>
      <xsl:for-each select="//SubLevel">
        <xsl:value-of select="ancestor::Level/@PayReceive"/><xsl:text>,</xsl:text>
        <xsl:value-of select="ancestor::Level/@CommodityName" /><xsl:text>,</xsl:text>

        <xsl:value-of select="@StartDate"/><xsl:text>,</xsl:text>
        <xsl:value-of select="@ClientPV"/>
        <xsl:text>&#xA;</xsl:text>
      </xsl:for-each>
    </xsl:template>
  </xsl:stylesheet>

With some changes to your stylesheet it will do:

Because there should be a line in output for each SubLevel, iterate first to SubLevel. Access additional information from SubLevel with ancestor::Level. Try:

<xsl:stylesheet version="1.0" 
                  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
                   >
    <xsl:output method="text" omit-xml-declaration="yes" indent="no"/>
    <xsl:template match="/">
      <xsl:text>PayReceive,CommodityName,StartDate,ClientPV</xsl:text>
      <xsl:text>&#xA;</xsl:text>
      <xsl:for-each select="//SubLevel">
        <xsl:value-of select="ancestor::Level/@PayReceive"/><xsl:text>,</xsl:text>
        <xsl:value-of select="ancestor::Level/@CommodityName" /><xsl:text>,</xsl:text>

        <xsl:value-of select="@StartDate"/><xsl:text>,</xsl:text>
        <xsl:value-of select="@ClientPV"/>
        <xsl:text>&#xA;</xsl:text>
      </xsl:for-each>
    </xsl:template>
  </xsl:stylesheet>
