Question

我想使用第二个table_A的（AcresDist1，txtAcresDist1，txtAcresDist1Total）XML列的新值更新table_B。

列P_XML属于XML类型。我知道如何一次更新单个列，但我想知道如何使用单个更新语句更新XML中的多个列。谢谢

SQL代码：

UPDATE S
SET
   P_XML.modify( N'replace value of (/FormValue/f1152_F1/Field[(id/text())[1]="AcresDist1"]/value/text())[1] with sql:column(''T.AcresDist1'')' )
 , P_XML.modify( N'replace value of (/FormValue/f1152_F1/Field[(id/text())[1]="txtAcresDist1"]/value/text())[1] with sql:column(''T.txtAcresDist'')' )
 , P_XML.modify( N'replace value of (/FormValue/f1152_F1/Field[(id/text())[1]="txtAcresDist1Total"]/value/text())[1] with sql:column(''T.txtAcresDist1Total'')' )
FROM   
    Table_A AS S
INNER JOIN 
    Table_B AS T ON s.P_NO = t.P_Number
                 AND s.FAC_RID = t.Fac_RID;

以下是请求的示例xml。谢谢。
