MSSQL - show data per page

- This statement will return record 1 to 20.

SELECT * FROM
(
SELECT row_number() OVER (ORDER BY id) AS rownum, *
FROM example_table_a
) AS A
WHERE A.rownum BETWEEN (1) AND (20)


- If you want the next 20, your where criteria should be:

WHERE A.rownum BETWEEN (21) AND (40)


- Finally, SQL statement in your C# code will be:

public String CreateSQL(Int32 pageNo, Int32 pageSize)
{
     StringBuilder _sbSQL = new StringBuilder();
     Int32 _offset = 1+ ((pageNo-1) * pageSize);

     _sbSQL.Append(" SELECT * FROM ");
     _sbSQL.Append(" ( ");
     _sbSQL.Append(" SELECT row_number() OVER (ORDER BY id) AS rownum, * ");
     _sbSQL.Append(" FROM example_table_a ");
     _sbSQL.Append(" ) AS A ");
     _sbSQL.Append(" WHERE A.rownum BETWEEN (" + _offset +") AND (" + (_offset-1) + " + " + pageSize + ")");

     return _sbSQL.ToString();
}

SAP CPI - Loop Process Call with SuccessFactor (oData V2)

Image
This example will show you how to fetch data from SuccessFactor (oData V2 Message Protocal) with a specific page size. For example, if your data has 10,000 total records and each record consists of 20 child nodes (the result size is around 10MB), you can fetch data by 500 records per request by using Loop Process Call. # My integration process consists of 1. Content Modifier " Initial Data " which I declare property "fetchData". 2. Loop Process Call " Loop Fetch Data " which calls Local Integration Process " Fetch Data From SF ". 3. Groovy Script which writes data from property "fetchData" in an attachment format. This example will focus on step 2 - Loop Process Call & Local Integration Process. # Local Integration Process "Fetch Data from SF".  How does it work? 1. Use Request Reply to call SuccessFactor to get data 500 records per request. 2. Use Groovy Script to get some fields and return in XML format. 3. Use XML to CS...
