[sqlite] sqlite3_prepare = SQLITE_BUSY????

[Daniel van Ham Colchete]

Hello people!

First of all:
SQLITE 3.3.6 with Gentoo Linux (updated)

I was trying to understand why would a sqlite3_prepare return
SQLITE_BUSY. I read the code at prepare.c and tokenize.c but I didn't
find anything.

When can a sqlite3_prepare (with a "select * from table where field1=?
and field2=?") returns SQLITE_BUSY?

Best regards,
