Updating Salesforce data with a SQL Server cursor

Easysoft customers use our Salesforce ODBC driver to work with Salesforce data in SQL Server. The following example shows how to update a Salesforce record from SQL Server by using a cursor:

  1. Configure a linked server that connects to Salesforce.
  2. Change the Linked Server > Linked Server Properties > Server Options > RPC Out setting to True.
  3. Adapt and then execute the following SQL: 
    -- This example changes the name of an account to 'GenePoint Inc'.
DROP TABLE Account
SELECT * INTO ACCOUNT FROM OPENQUERY(SFLINKEDSERVER,'SELECT ID, NAME FROM Account
                                     WHERE Id=''001i000000AOq3DAAT''')
SELECT * FROM ACCOUNT
UPDATE ACCOUNT SET [Name]='GenePoint Inc'
SELECT * FROM ACCOUNT

DECLARE @Id NVARCHAR(18)
DECLARE @Name NVARCHAR(255)
DECLARE @SQL NVARCHAR(MAX)

DECLARE LocAccCur CURSOR FOR SELECT Id, REPLACE([Name],'''', '''''') FROM Account
OPEN LocAccCur
FETCH NEXT FROM LocAccCur INTO @Id, @Name
WHILE @@FETCH_STATUS = 0
BEGIN
    PRINT 'Id : ' + @Id
    PRINT 'Name : ' + @Name
    SELECT @SQL='UPDATE Account SET [Name]='''+@Name+''' WHERE Id='''+@Id+''''
    EXEC(@SQL) at SFLINKEDSERVER
    FETCH NEXT FROM LocAccCur INTO @Id, @Name
END
CLOSE LocAccCur
DEALLOCATE LocAccCur
