c# - Approach for performing XSLT transformation on SQL Server -

-

i trying perform xslt transformation converting xml different xml format. using xslt extension objects perform data mapping operations during transformation.

i have mentioned cut down version of xml formats below. there mapping table maps supplier product code productid in system. while transforming use extension objects such mapping operations.

this works till time big xml document couple of 1000's of detail nodes in it. in such scenario extension object have performance impact.

i wondering whether can shift xslt transformation sql server , handle data mapping operation @ db level rather making individual db call extension objects?

source xml document

<suppliersdocument>   <supplierproducts>     <product>       <productcode>a001</productcode>       <uom>kg</uom>     </product>     <product>       <productcode>a002</productcode>       <uom>ml</uom>     </product>     <product>       <productcode>a003</productcode>       <uom>ea</uom>     </product>   </supplierproducts> </suppliersdocument>

target xml document

<mydocument>   <products>     <product>       <productid>998998</productid>       <unitofmeasurementid>1</unitofmeasurementid>     </product>     <product>       <productid>885855</productid>       <unitofmeasurementid>2521</unitofmeasurementid>     </product>     <product>       <productid>225235</productid>       <unitofmeasurementid>5542</unitofmeasurementid>     </product>   </products> </mydocument>

if you're not doing so, should in ssis, not in sql server itself.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
