Re: [Newbie] migrating a stored procedure from MSSQL to postgresql

As declared, your function returns TEXT, i.e. unlimited characters. <br /><tt>>>  CREATE FUNCTION
UpdateOrder(INTEGER)RETURNS <b>TEXT</b> AS</tt><p>Since your variable <br />>>  <tt>r_SKUPrice RECORD;</tt><br
/>containsa number of columns <br /><tt>>>  SELECT SKU, Price INTO r_SKUPrice</tt><br />you could create a
compositeTYPE that matches those columns <p>and <br />since your variable can contain a number of such rows, (see the
selectabove) <br />the function needs to become a set returning function <p>CREATE FUNCTION UpdateOrder(INTEGER)
