sqlite odbc

The biggest feature of SQLite is that you can save various types of data to any field without worrying about the data type declared by the field. For example, you can store strings in integer fields, floating point numbers in Boolean fields, or date values in numeric fields. But there is one exception: the field defined as integer primary key can only store 64-bit integers. When saving data other than Integers to this field, an error will occur. In ad

Efficient batch data insertion: Before giving the operation steps, let's briefly describe the concept of batch insert to help you read the subsequent sample code. In fact, batch insert is not a new concept. It is supported in the C interface APIs of other relational databases, but the interface implementation method

SQLite performance optimization instance sharing, sqlite performance optimization instance The first cache database to be found in iOS development was SQLite, which was also used as the backbone in the future. In the past, SQLite was not used to read and write large amounts of data, therefore, there is not much focus o

First, Introduction: SQLite is currently the most popular open source embedded database, and many other embedded storage engine (NoSQL), such as BerkeleyDB, Membase, and so on, SQLite can well support the basic characteristics of relational databases, such as standard SQL syntax, transactions, Data tables and indexes, and so on. In fact, although SQLite has the

ObjectiveWe know that any kind of relational database management system support SQL (structured Query Language), relative to the file management system, the user does not care how the data in the database access, do not need to know the underlying storage structure, familiar with SQL, you can use the database skillfully. The introduction of SQL makes the database system need to transform SQL into internal data structure, and then connect with the underlying storage structure to achieve the user

SQLite is a lightweight database and an acid-compliant associated database management system. It is designed to be embedded and has been used in many embedded products, it occupies very low resources. In embedded devices, it may only need several hundred KB of memory.

Dynamic ODBC loading in VC When using VC, VB, Delphi, and other advanced languages to write database applications, you often need to configure ODBC data sources on the control panel. It may be difficult for users to configure ODBC data sources. Moreover, in practical applications, users often require access to different data sources in the same
