I asked this question some time ago but with the current flurry of interest in external databases I will have another go. NB no components involved here.
If I have an external datafile held on the server how do I access it (purely for lookup) from a 4D client? What I tried was to use SQL as follows: Begin SQL USE DATABASE DATAFILE 'F:\AuthCodeEXT.4DD'; select LocAuthCode_LOOKUP.OSLAUA from LocAuthCode_LOOKUP where PCD2 = :cPC_Search into :acLocAuthCodes; USE DATABASE SQL_INTERNAL; End SQL and then to release the datafile with AUTO_CLOSE. This works fine in a very low usage context. I would like to use it in a busier scenario but am concerned that the datafile would often be locked. One suggestion I saw on the NUG was to access it from the server using the "Execute on Server" property on a method and then apparently the locking is taken care of by the 4D server. Has anybody tried this arrangement in a busy database (40-50 users and additional web cleints)?
