Re: [sqlite] library routine called out of sequence
Assuming that you are calling reset after each use of a prepared statement and/or that the error occurs on the very first bind... This sounds like in the working case the statements are prepared, bound, and then reset by the same thread each time these steps are done, but perhaps in the non-working case the statements are prepared in one thread and then bound in different threads (perhaps even on the first call to bind). I think that might be your issue. Which version of SQLite are you using, and what OS? Is thread support compiled in to your SQLite instance? Also, could two threads be attempting to bind the same statement at the same time? -Original Message- From: sqlite-users-boun...@sqlite.org [mailto:sqlite-users-boun...@sqlite.org] On Behalf Of Sreekumar TP Sent: Friday, December 23, 2011 9:06 AM To: General Discussion of SQLite Database Subject: Re: [sqlite] library routine called out of sequence Hi, yes, I know.

I am 99% certain that it is the very first call. unless the step and reset executed once before.(the bind , step, reset is in a loop). I will double check this. Sreekumar ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

If difference between working and non-working is reusing statements then it's probably not the first bind, but first after statement was already executed.

Hi , I have a strange problem. I do the following in sequence - 1. open database 2. set pragmas 3.create table 4. prepare a paremetrised statement ( SELECT ..) 5. bind values to the statement 6. step At 5, I get the error "library routine called out of sequence".

It is not a bug - it is a limitation. Aggregate functions are not reentrant. Changing this for the step function appears to be just two lines of code. Probably it two additional lines of code to do the same for the finalizer function. Testing the change to verify that it works and does not introduce new bugs, however, will likely take a few hundred lines of test code and corresponding time.

Re: [sqlite] library routine called out of sequence
My answer wasn't complete. If you populate a database using sqlite3 and exit sqlite3 the DB is closed. To access it from a C program you have to first open it with sqlite3_open. Sqlite is not an SQL server but instead a library which is linked into every application. Think of it just as a smart file and treat it as you would opening and closing a file in your programs.

The sqlite3 program automatically opens the database and holds it open. It will create one if it is missing. The DB stays open until you exit Sqlite3.

[sqlite] library routine called out of sequence
Good morning. I just subscribed to the list. I've been using Sqlite for an year without problems, but recently I have to face up quite often with the error "library routine called out of sequence" and it seems I can't solve it definitely. I'll explain better: I'm programming under Linux (I'm not very skilled in Linux) and using 2.8.5 library version (july 2003) after downloading 2.8.5.tar.gz file from your site. In practice I produced the library files libsqlite.a, libsqlite.la, libsqlite.lai, libsqlite.so, libsqlite.so.0, libsqlite.so.0.86 using the flag THREADSAFE = 1. My program contains 4 threads all accessing the same database Sqlite, a file called MwpCom.sql, composed by many tables. Every thread updates or makes sql inserts in his own tables, but, as I wrote, all the tables belong to same file MwpCom.sql. During my first tests I used to share between the 4 threads the pointer returned by sqlite_open() , to tell the truth I used many sqlite_open() so I shared many pointers, all pointing to the same file Sqlite. I always obtained the error "library routine called out of sequence" while trying to access any table. Later, reading some hints about Sqlite concurrency, I discovered that this way of using pointers was wrong, so I changed my code in order not to share the pointers anymore (every thread now has his own connections, alias his own sqlite_open()), and things improved immediately. But unfortunately sometimes one of the 4 threads, while attempting to access his tables, gives "library routine called out of sequence". I don't know what to do. If I restart my program for a while it runs ok, so I think the database isn't corrupted, but first or later, i get the error. Can you suggest me something? Should I try with the last release of libraries (2.8.15) ? I hope you can help me. Thank you in advance.
