POS: Execute stored procedure

This blog post will show you some ways to execute stored procedures from POS using standard API: SqlStoredProcedure and DBUtil from DataAccess DLL.


Let’s imagine we need to execute stored procedure [dbo].[TESTPROCEDURENAME] with 2 input parameters: param1 and param2.


A. Execute Stored procedure that returns data rows


In this case stored procedure returns the set of records.


using LSRetailPosis.DataAccess;

using LSRetailPosis.Settings;

 

SqlStoredProcedure sqlStoredProcedure = new SqlStoredProcedure("[dbo].[TESTPROCEDURENAME]");

sqlStoredProcedure.Add("@param1", param1Value);

sqlStoredProcedure.Add("@param2", param2Value);

 

var dbUtil = new DBUtil(ApplicationSettings.Database.LocalConnection);

 

using (DataTable dataTable = this.DBUtil.ExecuteStoredProcedureWithData(sqlStoredProcedure))

{

    foreach (DataRow dataRow in dataTable.Rows)

    {

        //process data returned by procedure

    }

}


B. Execute Stored procedure that returns scalar value


In this case stored procedure returns single (scalar) value: number, string, date, etc.


using LSRetailPosis.DataAccess;

using LSRetailPosis.Settings;

SqlStoredProcedure sqlStoredProcedure = new SqlStoredProcedure("[dbo].[TESTPROCEDURENAME]");

sqlStoredProcedure.Add("@param1", param1Value);

sqlStoredProcedure.Add("@param2", param2Value);

 

var dbUtil = new DBUtil(ApplicationSettings.Database.LocalConnection);

var result = this.DBUtil.ExecuteStoredProcedureWithDataScalar(sqlStoredProcedure));

 

//now you need to convert result to appropriate type (bool, string, int, etc.)
