Of STORES and Files |

Jeff Cook Aspect Systems Ltd | Hi
I know how to create a STORE e.g. apmDM.EDBSession.Execute ('CREATE STORE "ExportFiles" AS LOCAL PATH ''ExportFilesStore'''); .... and I can use a SaveDialog to get the filename and path to where a file needs to go. And I can export my data to a STORE as I can't go directly to a path/filename e.g. apmDM.EDBMemory.Execute('EXPORT TABLE "' + sTempFileName + '" TO "' + apmDM.EDBEngine.QuotedSQLStr (ExtractFileName(SaveDialog.FileName)) + '" IN STORE "ExportFiles" ' + sl.CommaText /* column names */ + ' FORMAT DELIMITED INCLUDE HEADERS'); BUT how do I copy the file from a STORE to the path from my SaveDialog? I suppose I could create a new STORE each time with the path from the SaveDialog and drop the STORE without deleting the data. In a multiuser environment, I'd then have to create a unique STORE name for this process. Is that the answer or there a smarter way? Also, with wider relevance, how do I know if a STORE already exists. The STORE is at a higher level than an individual database, so 'SELECT * FROM Information.??? WHERE Name ..." isn't going to work. Is there a HigherInformation table hiding somewhere? I could use a try/except block to detect an attempted duplicate "CREATE STORE", but is there a nicer way?

Yes, you could create a new store or use SaveStoreFileToStream and then save to file. Or if it is a local store then query the Configuration DB for the store and path and copy the file using regular file copy methods. > Also, with wider relevance, how do I know if a STORE already exists.

You'd have to query Configuration database (Stores table): http://www.elevatesoft.com/manual?action=viewtopic&id=edb2sql&topic=Configuration_Database Raul |

Save to stream then save the stream to a file - simple! > Or if it is a local store then query the Configuration DB for the store > and path and copy the file using regular file copy methods. > > You'd have to query Configuration database (Stores table): > > http://www.elevatesoft.com/manual?action=viewtopic&id=edb2sql&topic=Configuration_Database > OK, great, now I'm off and running - I must have skipped this database when reading up on EDB. Heaps of good stuff in here. Cheers Jeff -- Jeff Cook Aspect Systems Ltd www.aspect.co.nz |

<< BUT how do I copy the file from a STORE to the path from my SaveDialog? >> Is the path always local on the client ? If so, then you would use this method: http://www.elevatesoft.com/manual?action=viewmethod&id=edb2&product=delphi&version=7&comp=TEDBSession&method=SaveStoreFileToStream The EDB Manager also has source code that even shows you how to do a "direct edit" on a store file by saving the store file to the temp directory using the above method, doing a checksum, shell-executing the file, re-doing the checksum, and then saving the file back to the store on the EDB Server.
