Hello,
I must be missing something obvious, but I can't figure out how to
compile/install the tcl bindings. I've been trying to install
sqlite-3.3.5 for the last few hours.
According to http://www.sqlite.org/quickstart.html, in order to use
the tcl interface I need this line in my tcl script:
Hi Len,

Here is what I have found: If I open a mem DB with sqlite3_open

Is it possible to use the LIKE operator with a prepared statement?
I'm trying to build a query that uses binding for the text in the LIKE
operation as follows:

Provided your new database has the features you are using it is simple.
For example we use Sqlite and PostgreSQL and transferring between them
is simple. Even the application program API is similar so a conditional
compile in the programs takes care of that and links appropriately.

Are you sure that $dbh0>(sqlite_version) returns the same thing as
executing the following SQL:
select sqlite_version();
I don't use perl, so I'm not sure how you actually execute the query.
One other possibility, you may have a wrapper that is statically
linked to an older library and

Sqlite works very well for web applications unless they are large and
very busy. It is easy to manage and backup and performs well.
For a larger scale operation PostgreSQL would be a better choice than
MySql. If you design your application with care you could switch from

Hi Lenster,
For a Web application you are probably better off with MySQL, it runs as
a seperate process and handles multiple threads really well. I'm
