Hello,

I am trying to handle a SQLite3 table with D. During my 
researchs, I discovered the lib 
https://dlang.org/phobos/etc_c_sqlite3.html.

However, for any reason, there is no code snippets or sample 
codes available there. So, I am stucked.

I have the following sample structure table:
   sql = "INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) "  \
         "VALUES (1, 'Paul', 32, 'California', 20000.00 ); " \
         "INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) "  \
         "VALUES (2, 'Allen', 25, 'Texas', 15000.00 ); "     \
         "INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY)" \
         "VALUES (3, 'Teddy', 23, 'Norway', 20000.00 );" \
         "INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY)" \
         "VALUES (4, 'Mark', 25, 'Rich-Mond ', 65000.00 );";

Can you pls provide a code snippet or some hints to the 
following job:
- Create a table with the layout above
- Iterate through the records given a basic SELECT WHERE Query

Thanks in advance, AN

Snippet how to do it using DDBC library 
https://github.com/buggins/ddbc

    import ddbc;

    string url = "sqlite:testdb.sqlite";
    // creating Connection
    auto conn = createConnection(url);
    scope(exit) conn.close();
    // creating Statement
    auto stmt = conn.createStatement();
    scope(exit) stmt.close();
    // execute simple queries to create and fill table
    stmt.executeUpdate("CREATE TABLE COMPANY (ID int, NAME 
varchar, AGE int,ADDRESS varchar, SALARY double)");
    string[] statements = [
        "INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) VALUES 
(1, 'Paul', 32, 'California', 20000.00 )",
        "INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) VALUES 
(2, 'Allen', 25, 'Texas', 15000.00 )",
        "INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) VALUES 
(3, 'Teddy', 23, 'Norway', 20000.00 )"
    ];
    foreach(sql; statements)
        stmt.executeUpdate(sql);
