Re: [sqlite] Encryption using System.Data.SQLite.dll
Hi, I am creating an sqlite3 interface to an existing data model. For that purpose sqlite3 tables are dynamically loaded. I'm using /sqlite3_column_count/ and /sqlite3_column_table_name/ to load data into relevant tables only. Now, I am having problems with queries such as: SELECT a.column1 FROM table1 AS a, table2 AS b; however this works: SELECT a.column1, b.column1 FROM table1 AS a, table2 AS b; because /sqlite3_column_table_name /only returns columns in the result set. Is there a way to get the table names that were referenced in the query itself? Thanks in advance, bishwa ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

Consider that you might do things like SELECT 1,2,3; SELECT (a.column1 + b.column1) FROM table1 AS a, table2 AS b; so it's quite possible that values returned aren't from any table at all.

Re: [sqlite] How to find table names referenced in the query, not in the result set
You can try to use authorizer (http://www.sqlite.org/c3ref/set_authorizer.html) although it seems to me SQLite won't inform you about access to table2 in the first query.

[sqlite] SQLite Provider cannot be found error
Hello, I am trying to convert and ASP page to ASP.NET on Windows 2008 R2. The program I converted previously read in data from multiple Microsoft Access databases, looping through each directory under a directory called pub. The data in the tables is created from a software package called eMill, which sends emails in batches. The ASP page provides totals on how many emails were sent out for each letter type for that day. We are upgrading our eMill application and the new version of the software writes to SQLite databases instead of Microsoft Access db's. I have installed .NET 4.0 (dotNetFx40_Full_x86_x64.exe) on the new server, as well as System.Data.SQLite for .NET 4.0 (sqlite-netFx40-setup-bundle-x64-2010-1.0.81.0.exe), and the program is getting an error Provider cannot be found. It may not be properly installed when trying to open the SQLite databases. The only differences in this program from one that works with Microsoft Access is the provider name (System.Data.SQLite instead of Microsoft.Jet.OLEDB.4.0) and the database names (store.db3 instead of Messages.mdb). Here is a portion of the code, the complete aspx file is attached as txt: --- % dim rs,x, conn, dir conn=Server.CreateObject(ADODB.Connection) 'conn.provider=Microsoft.Jet.OLEDB.4.0 conn.provider=System.Data.SQLite conn.Mode = 1 'conn.open(server.mappath(..\pub\ folder.name \Messages.mdb)) conn.open(server.mappath(..\pub\ folder.name \store.db3)) rs=Server.CreateObject(ADODB.Recordset) The line of code that gets the error is the open of the database. I have tried many things to get rid of this error, among them: registered the System.Data.SQLite.dll, added C:\Program Files\System.Data.SQLite\2010\bin to the PATH variable, re-installed System.Data.SQLite - checked first box to create assemblies, re-installed System.Data.SQLite again - checked second box to create GAC, modified the web_config, with and without the version and publickeytoken (Version=1.0.81.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139), . Does anyone know if there is something that I need to do differently in the code to access the SQLite databases? Or is there something wrong with the environment? Could it be a permissions problem? Is there a way I can increase the debug level to get a better log of the error? (I do not currently have Visual Studio installed on the server). Any help or ideas on how to fix this would be much appreciated. Thanks!

[sqlite] Question about memory consumption of SQLite
Hi I am writing an application which creates a db in runtime (i.e. only INSERT queries are performed, indexing only by primary key...) I am running with the following pragmas: executeString(PRAGMA temp_store=MEMORY); executeString(PRAGMA journal_mode = MEMORY;); executeString(PRAGMA page_size = 8192;); executeString(PRAGMA cache_size=1;); how much memory on heap will the application consume (from SQLite point of view). at most ? is there a rule of thumb here ? (i mean, I assume that page_size* cache_size matters... but what else ?) cheers Tal ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
