- Alfred Newman (31/81) Nov 01 2016 Hello Vadim,
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

So, I am stucked.etc.c.sqlite3 is just a C wrapper, take a look at C examples for sqlite3. The D docs don't usually include documentation for simple C wrappers. If you want a proper D library for sqlite3, try d2sqlite3 from dub. IMO it's really easy to use and works really well. Your example using d2sqlite3: auto stmt = db.prepare("INSERT INTO COMPANY (ID, NAME, AGE, ADDRESS, SALARY) VALUES (:id, :name, :age, :address, :salary)"); stmt.inject(1, "Paul", 32, "California", 20000); stmt.inject(2, "Allen", 25, "Texas", 15000); stmt.inject(3, "Teddy", 23, "Norway", 20000); stmt.inject(4, "Mark", 25, "Rich-Mond", 65000);
