The error is not occurring until later, the first time you
try to access the database using the dbcomm object.

[sqlite] Impossible to "catch locked state" (SQLite 3.5.6 & TCL)
I'm afraid, I've discovered a bug: there's no possibility to "catch" the
error "database is locked". Even, when one's trying something like:
#v+
if { [catch {sqlite3 dbcomm $fullPathToDatabaseFile} err] } {
puts $err
}
#v-
There'll be no $err output, because - as it seems - "catch" won't return
a value > 0. There'll be following lines printed on the console instead:
database is locked
while evaluating {source ./main.tcl}

Re: [sqlite] [C] Linker Error
Hi Folks Thanks for your answers. I already had the latest build, and i linked the lib correctly with my Linker. I found the solution in the meantime. It was quite easy actually: I only had to manually add the -ldl option to my linker and all worked fine. Thanks anyway for your support :) Kind regards Severin -- Severin A.

Looks like you need to include the shared library archive into your LIB list.

It is a single file of C code named sqlite3.c. Compile it and statically link it with your application. But even then, you're going to get the same linker errors because you have omitted the "-ldl" option when you link. -- D.

[sqlite] [C] Linker Error
Hi folks I tried to include sqlite3 in my current C Project. I downloaded the precompiled library sqlite-3.5.6.so and put it in my project.

Re: [sqlite] Odd problem with select on large table
Hi James, > / > sqlite3 test.db `select name from PerfTest1 where name = > "key5000"' > > does work. I know this because if I query for "key500" I get back > that row. It may work, but it's still wrong ;-) You should use single quotes for literals, which is correct SQL syntax. SQLite should give an error for double quotes unless it's a column or table name. SQLite doesn't generate an error, unfortunately, because it allows for some cross compatibility with MSSQL or something that permits double quoted literals. That allowance, however, is not standard SQL and causes a host of problems. I'm hoping it will be removed from SQLite.
