用xml作参数一次插入多条数据

1.存储过程方法：

declare @customers xml
set @customers='<cus bpNo=''15'' MNo=''商户ID1'' MName=''商户名称1'' /><cus bpNo=''15'' MNo=''商户ID2'' MName=''商户名称2'' />'

INSERT control.tb_ExternalEnterprise(BPNo,EnterpriseId,EnterpriseName)
SELECT R.c.value('@bpNo','CHAR(6)'),R.c.value('@MNo','VARCHAR(50)'),
R.c.value('@MName','NVARCHAR(30)')
FROM @customers.nodes('cus') R(c)

2.sql语句方法：

INSERT tb_ExternalEnterprise(BPNo,EnterpriseId,EnterpriseName)
SELECT b.*
FROM (select cast('<cus bpNo=''15'' MNo=''商户ID1'' MName=''商户名称1''/>
<cus bpNo=''15'' MNo=''商户ID2'' MName=''商户名称2'' />' as xml) a)t
cross apply(select R.c.value('@bpNo','CHAR(6)') as bpNo,
R.c.value('@MNo','VARCHAR(50)') as MNo,
R.c.value('@MName','NVARCHAR(30)') as MName
from t.a.nodes('cus') R(c)) b

System.Text.StringBuilder sb = new System.Text.StringBuilder("'");
for (int i = 0; i < count; i++)
{
sb.AppendFormat("<cus bpNo='{0}' />", i.ToString());//Guid.NewGuid().ToString());
}
sb.Append("'");
