Execute sql query in sdk

I am using SAP Business One 9.2. I have a user defined table and I am using ADO.NET for executing sql query.

[code]

strQuery = "DELETE FROM [@U_RDLCH_ITEM_SERIAL] WHERE U_DC_No=10"

ExecuteQuery(strQuery)

[/code]

In the ExecuteQuery function , I have used ADO.NET for executing this query.Is there any way in sdk to execute such query ?
