为了摆脱这个错误,我尝试了很多方法,但我没有成功。我是新手,我试图从所有其他问题中找出答案,也尝试了一些建议,但没有奏效。

这是代码:

- (void) addObiectAsigurat
{
sqlite3 *database = nil;
sqlite3_stmt *addStmt = nil;

if(sqlite3_open([[Database getDBPath] UTF8String], &database) == SQLITE_OK) 
{

    if(addStmt == nil) {
        const char *sql = "INSERT INTO ObiectAsigurat (IdIntern, TipObiect, JSONText) Values(?, ?, ?)";
        if(sqlite3_prepare_v2(database, sql, -1, &addStmt, NULL) != SQLITE_OK)
            NSAssert1(0, @"Error while creating add statement. '%s'", sqlite3_errmsg(database));
    }

    sqlite3_bind_text(addStmt, 1, [IdIntern UTF8String], -1, SQLITE_TRANSIENT);
    sqlite3_bind_int(addStmt, 2, TipObiect); 
    sqlite3_bind_text(addStmt, 3, [JSONText UTF8String], -1, SQLITE_TRANSIENT);


    if(SQLITE_DONE != sqlite3_step(addStmt))
        NSAssert1(0, @"Error while inserting data. '%s'", sqlite3_errmsg(database));
    else {
        sqlite3_finalize(addStmt);
        sqlite3_close(database);
    }

如果我在此方法结束时使用它


}
else sqlite3_finalize(addStmt);

sqlite3_close(database);
}

那么我的错误如下所示:

Assertion failure in -[YTOObiectAsigurat addObiectAsigurat] 
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Error while inserting data. 'database is locked''
*** First throw call stack:

libc++abi.dylib: terminate called throwing an exception

如果我用这个


    sqlite3_finalize(addStmt);
    }
sqlite3_close(database);
}

我得到坏线程1:

编辑:我很容易解决了我的问题。

我没有在插入、更新、删除的方法中完成并关闭数据库,我只是重置了语句,然后将其设为 nil。在此之后,我声明了一个方法 finalize,在此我关闭数据库并最终确定语句。也许这个想法会对某人有所帮助。

  1. 确保在使用它的其他方法中关闭数据库连接。

  2. 由于您在循环中调用您的方法,因此当您需要批量插入数据时,使用数据库有更有效的方法:重建您的应用程序以循环访问 INSERT 中的值,如下所示:这只是一个示例,在此处插入正确的值

    -(void)insertValuesFromArray:(NSMutableArray *)array {
    
    sqlite3 * database;
    
    const char *dbpath = [[Database getDBPath] UTF8String];
    
    if (sqlite3_open(dbpath, &database) == SQLITE_OK)
    {
        sqlite3_exec(database, "BEGIN TRANSACTION", 0, 0, 0);
        const char *sqlStatement = "INSERT INTO ObiectAsigurat (IdIntern) Values(?)";
        sqlite3_stmt *compiledStatement;
    
        if (sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) {
            int hasError = 0;
    
            for (int i=0; i<[array count]; i++) {
                sqlite3_bind_text(compiledStatement, 1, [[array objectAtIndex:i] UTF8String], -1, SQLITE_TRANSIENT);
    
    
                if (sqlite3_step(compiledStatement) != SQLITE_DONE) {
                    hasError=1;
                    NSLog(@"Prepare-error %s", sqlite3_errmsg(database));
                }
    
                sqlite3_reset(compiledStatement);
            }
    
            sqlite3_finalize(compiledStatement);
    
            if( hasError == 0 ) {
                sqlite3_exec(database, "COMMIT", 0, 0, 0);
                NSLog(@"inserted successfully");
            }
            else {
                sqlite3_exec(contactDB, "ROLLBACK", 0, 0, 0);
                NSLog(@"can't insert:");
            }
        }
        sqlite3_close(contactDB);

一种可能性是您没有提交插入事务。搜索如何提交并尝试一些解决方案。

以下可能会有所帮助

如果您已经尝试过,请忽略....
