Question

When running the following prepare statement for a SQLite3 db-selecct query I get a SQLLite Error 21 “Library routine called out of sequence“:

sqlite3             *lDb;
sqlite3_stmt           *lStmt;
NSNumberFormatter     *lNbrFmt = [[[NSNumberFormatter alloc] init] autorelease];

// Define SQL statement 
NSString *lSql = @"SELECT section, language, title, description"
@"                        selector-x-pos, selector-y-pos, gps-x-pos, gps-y-pos"
@"                   FROM sections"
@"               ORDER BY section ASC";

lSqlResult = sqlite3_prepare_v2(lDb, [lSql UTF8String], -1, &lStmt, NULL);
NSLog(@"%@", [NSString stringWithUTF8String:sqlite3_errmsg(lDb)]);

What am I doing wrong?

Answer 1

Uopon further investigation I found my mistake. I should have first opened the db before running the prep statement.

The code should look like this:

sqlite3             *lDb;
sqlite3_stmt           *lStmt;
NSNumberFormatter     *lNbrFmt = [[[NSNumberFormatter alloc] init] autorelease];

// Define SQL statement 
NSString *lSql = @"SELECT section, language, title, description"
@"                        selector-x-pos, selector-y-pos, gps-x-pos, gps-y-pos"
@"                   FROM sections"
@"               ORDER BY section ASC";

if(sqlite3_open([[fileMethods databasePath] UTF8String], &lDb) == SQLITE_OK) {
    lSqlResult = sqlite3_prepare_v2(lDb, [lSql UTF8String], -1, &lStmt, NULL);
    NSLog(@"%@", [NSString stringWithUTF8String:sqlite3_errmsg(lDb)]);
