Kuv twb pom tej yam ua tau txawv txawv thiab ruaj tes-encoding RdbCommandText nyob hauv ib co piv txwv ntawm cov (xws li lwm cov ntaub ntawv MSDN).

Kuv xav taw tes rau cov tuaj tshiab rau BDC tias commands yuav muab qhwv hauv ib CDATA lossis nyob rau "natural lawv" daim ntawv. Li ntawd, qhov kev siv ua tau txawv txawv:

<Khoom Lub npe="RdbCommandText" Hom="System.String">
  QHO dbo.MCRS_SETTLEMENT.ID, dbo.MCRS_SETTLEMENT.Settlement los ntawm dbo.MCRS_SETTLEMENT 
    QHOV TWG (tus ID &gt;= @MinId) THIAB (tus ID &LT;= @MaxId)
</Khoom>

uas muaj yeej yuav zoo dua tuaj li no:

<Khoom Lub npe="RdbCommandText" Hom="System.String">
<![CDATA[
QHO dbo.MCRS_SETTLEMENT.ID, dbo.MCRS_SETTLEMENT.Settlement los ntawm dbo.MCRS_SETTLEMENT
QHOV TWG (tus ID >= @MinId) THIAB (tus ID <= @MaxId)
]]>
</Khoom>
