Re: [sqlite] Basic Text Bind Question
Ok, thanks for the responses. --Ulrik >I think it stops right here, because you've got fname twice. That >induces an error. You are correct, I'm not sure when I introduced that error, but thanks for pointing it out. Its not in my running code so it was either C/P error or something else dumb. -- Dr. H & Ted Ok, I see what you guys are saying. I split my code up so I create and populate the database with another set of sqlite3_exec() statements. I confirmed the database is populated with the following results: $ ./sqlite3 test.db SQLite version 3.2.1 Enter ".help" for instructions sqlite> select * from People; fname|lname John|Fullman Mike|Fullman Mike|Smith My select code is as follows: sqlite3_open( "test.db", ); size = sprintf( buf, "SELECT * FROM People WHERE lname = '?'" ); iPrep = sqlite3_prepare( database, buf, size, , 0 ); sqlite3_bind_text(statement, 1, "Fullman", 7, SQLITE_STATIC ); rc = sqlite3_step(statement); std::cout << rc << " " << SQLITE_DONE; I would expect rc to be SQLITE_ROW, but it is SQLITE_DONE. I undertand with getting multiple row back I will need to loop the sqlite3_step function later. -- Kiel W. [EMAIL PROTECTED] -- >> time is swift <<

But after you get that fixed up, you also need to leave out the quotes around the question mark. With the quotes in, this is a literal question mark, not an SQL variable. Replace the SQL you have with: "SELECT * FROM People WHERE lname = ?" __ Discover Yahoo! Use Yahoo! to plan a weekend, have fun online and more. Check it out! http://discover.yahoo.com/

It then returns a pointer to the beginning of the second statement so that you can process them all in a loop. But your code appears to omit this loop and thus is processing only the first one. It never reaches the SELECT. -- D. Richard Hipp <[EMAIL PROTECTED]>
