I have a bunch of SQL statements to execute on a database. (I'm doing things that Rails doesn't provide methods for, as far as I know: creating views, adding foreign keys, etc. It's mostly for non-Rails interaction with the data.) In essence, I'm doing the following: sql = "statement_1; statement_2; statement_3; etc;" ActiveRecord::...

Dear fellow members, It's nice to find such a useful site with genius members. I have been trying to find a solution for this SQLITE problem for a while now. Google didn't help me, except in finding this website. The SQL query works fine on the MSAccess version of the same database. Here's my SQL statement - which didn't work for me. ...
It's impossible to sqlite3_bind_text a table name because sqlite3_prepare_v2 fails to prepare a statement such as: SELECT * FROM ? ; I presume the table name is needed to parse the statement, so the quoting needs to happend before sqlite3_prepare_v2.

I've used sqlite a lot with Ruby, and love it, but this is my first time using it with PHP. Basically, in order to get SQlite3 to be able to insert into the db...
