View source for Updating Shipping Rates

It's possible to update the shipping rates in CMS without installing an update. This can be done with SQL inputs using the files that the installer uses. Statements are below. The files referenced here must be obtained from Dev or can be pulled from the %temp% directory (e.g. C:\Users\RUSSHO~1\AppData\Local\Temp\{8C2B21D6-A9F2-4AD9-89A0-162571D179E8}) after an install has started.

<source lang="tsql">
DELETE FROM SHIPRATES;
INPUT INTO SHIPRATES FROM C:\TEMP\SHIPRATES.DAT;

DELETE FROM SHIPDEFAULTS;
INPUT INTO SHIPDEFAULTS (shipdefaultsid,description,defaultvalue) FROM C:\TEMP\SHIPDEFAULTS.CSV

WARNING: The latter query will overwrite any rates manually set in CMS Setup so you should confirm the user has not explicitly set those rate overrides before running the SQL.
</source>

Note that CMS updates may contain other related updates like new shipping methods, changes to existing shipping options, and/or shipping integration changes that would not be encompassed by these rate only inputs.
