![]() The process in vulnerable to errors as each time that file is opened the HSQLdb database element has to be extracted into memory, and rolled up again into a single file again when closed. AOO Base with its embedded HSQLdb 1.8 tries to emulate MS Access by zipping the two elements into a single. MS Access is designed to simplify the tasks for the user by including both the Client and Server in a single software package, and it tends to conceal from the user the underlying SQL communication between the two. The Client software provides the means by which the user communicates with the Server to enter, update or make use of that data. The Server software provides the database management system that stores the data systematically to permit its entry and retieval. Generally software for an effective relational database comprises at least two elements - a back-end or Server and a front-end or Client: very often the two are on separate computers but can equally be located on a single computer. I see Villeroy's comment in many places "Base is not a database", what do you mean by that? TO_CHAR converts the Table4 D field to CHAR that is passed to the Table5 D field The lower case 'Table*' words needed to be double quotedĢ. ![]() INSERT INTO "Table5" (A, D) SELECT A, TO_CHAR(D,'YYYY-MM-DD') FROM "Table4" ġ. The Base status bar shows: JDBC hsqldb:file:///C:\Bill\.Įdit: After visiting, this statement works! I am running a split database with macros according to DACM's post: viewtopic.php?f=83&t=61183. My question is: what is the syntax for SELECT INTO where date fields are to be copied? User lacks privilege or object not found: TABLE5 The Execute SQL Statement error I usually get is: INSERT INTO Table5 (A, #D#) SELECT A, 'D' FROM Table4 INSERT INTO Table5 (A, 'D') SELECT A, 'D' FROM Table4 INSERT INTO Table5 (A, D) SELECT A, 'D' FROM Table4 " statement work, I have tried the following commands, all unsuccessfully: I have entered the following two rows of data into Table5: I have also created Table5 with the same configuration as Table4. Putting ' around the date field was successful: "SELECT 'D' FROM Table4 "Īuto -increment statement: GENERATED BY DEFAULT AS IDENTITY ![]() After many trials I found the statement "SELECT D FROM Table4 " fails if D is a date field. In Base I want to write SQL like "INSERT INTO Table5 SELECT * FROM Table4 " i,e I want to append the contents of Table4 to Table5. Viewtopic.php?f=83&t=61183 " Create a new 'split' HSQL 2.x database" viewtopic.php?f=83&t=17567#p162653 " Avoiding data loss with built in HSQLDB" I have read comments about "HSQLDB Embedded bad choice" with soutions that I need to re-read, understand and implement so my fairly simple database project is not simple any more: I see Villeroy's comment in many places "Base is not a database", what do you mean by that? Is there any documentation you can point me to explain this comment? This limitation is a serious limitation for me but Base is free so I have to accept the bad with the good unless somebody can point me to a workable solution.

If you cannot follow the instructions ask someone with more PC skills to help you. d) and e) will recover your file as it was when you last opened or you last saved it. How to find and un-delete AOO temporary files has detailed instructions on how toĪ) use Previous Versions (W7 and later) to recover previous versions of the file (is there something similar on MacOS and Linux?) ī) recover your file as it was when you last opened or saved it, or as it was when it was last saved with AutoRecovery Ĭ) find previous versions of the file in the folder it is located in, but which have since been deleted ĭ) find any temporary files AOO wrote while you were editing the file but which have not yet been deleted Į) un-delete the temporary files AOO wrote while you were editing the file, and then deleted. Upload the broken file so it can be analysed and possibly repaired. If you had a backup it would be a matter of seconds to get back your file. It should allow to recover a previous version of the file.Īnyone not backing up important files is being extremely foolish and is asking for trouble. See the tutorial on un-deleting temporary files.
