如何在sqlite + juce中創建表格和插入數據

Question

請問如何在sqlite中創建數據庫。請告訴我如何在sqlite + C++中創建表格和插入數據。幫助互聯網。請給我一些例子，以便我能夠理解。

Answer 1

這是我如何做到這一點：

char *sql; 
int rc = 0; 

File *fptr_db = new File(DBPath); 

if(fptr_db->existsAsFile()) 
{ 

} else { 
    sqlite3_initialize(); 
    rc = sqlite3_open_v2(DBPath.toRawUTF8(), &pDb, SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE, NULL); 
    if (rc != SQLITE_OK) { 
     sqlite3_close(pDb); 
     exit(-1); 
    } 
    sql = "CREATE TABLE IF NOT EXISTS Users (Id integer PRIMARY KEY NOT NULL, GroupId integer NOT NULL, Name VARCHAR(40) NOT NULL COLLATE NOCASE, Password VARCHAR(200) COLLATE NOCASE, Address VARCHAR(200) COLLATE NOCASE, PostalCode VARCHAR(20), Vat VARCHAR(30), BI INT, LastSale DATE, Limits DECIMAL(12,6), Commission DECIMAL(12,6), BirthDate DATE, Phone VARCHAR(20), MobilePhone VARCHAR(20), Email VARCHAR(200) COLLATE NOCASE, Obs VARCHAR, DefaultSerieId integer NOT NULL); "; 
    rc = sqlite3_prepare_v2(pDb, sql, -1, &query, NULL); 
    if (rc != SQLITE_OK) exit(-1); 
    rc = sqlite3_step(query); 
    if (rc != SQLITE_DONE) exit (-1); 

    sql = "INSERT INTO [Users] ([Id], [GroupId], [Name], [Password], [DefaultSerieId]) VALUES (1, 0, 'Paulo', '1234', 0)"; 
    rc = sqlite3_prepare_v2(pDb, sql, -1, &query, NULL); 
    if (rc != SQLITE_OK) exit(-1); 
    rc = sqlite3_step(query); 
    if (rc != SQLITE_DONE) exit (-1); 

    sql = "INSERT INTO [Users] ([Id], [GroupId], [Name], [Password], [DefaultSerieId]) VALUES (2, 0, 'Antonio', '', 0)"; 
    rc = sqlite3_prepare_v2(pDb, sql, -1, &query, NULL); 
    if (rc != SQLITE_OK) exit(-1); 
    rc = sqlite3_step(query); 
    if (rc != SQLITE_DONE) exit(-1); 

    sqlite3_finalize(query); 

    sqlite3_close(pDb); 
    sqlite3_shutdown(); 
} 

效果很好，DBPATH是包含數據庫的路徑和名稱爲敲定的字符串。例如： String DBPath =「C：\ database.db」;
