一个 Swift 系统库包 (Apache, ApachePortableRuntime 和 APRUtil 的 C 语言封装)。这个包是 mod_swift 项目的一部分。

重要: 这个版本的包需要你安装 mod_swift。它会安装必要的垫片层 (shims)。

import PackageDescription

let package = Package(
  name: "MyTool",
	
  dependencies: [
    .Package(url: "git@github.com:modswift/CApache.git", from: "2.0.0"),
  ]
)

import CAPR
import CAPRUtil

let connectString = "OpenGroupware.sqlite3"
let sql = "SELECT company_id, login FROM person"

var pool         : OpaquePointer? = nil
var driverHandle : OpaquePointer? = nil
var con          : OpaquePointer? = nil
var res          : OpaquePointer? = nil

apr_pool_initialize()
apr_pool_create_ex(&pool, nil, nil, nil)
apr_dbd_init(pool)
apr_dbd_get_driver(pool, "sqlite3", &driverHandle)
apr_dbd_open(driverHandle, pool, connectString, &con)

apr_dbd_select(driverHandle, pool, con, &res, sql, 0)

var row : OpaquePointer? = nil
while true {
  let rc = apr_dbd_get_row(driverHandle, pool, res, &row, Int32(-1))
  guard rc == 0 else { break }
  
  print("record:")
  let colCount = apr_dbd_num_cols(driverHandle, res)
  for colIdx in 0..<colCount {
    let name : String
    if let cstr = apr_dbd_get_name(driverHandle, res, colIdx) {
      name = String(cString: cstr)
    }
    else {
      name = "[\(colIdx)]"
    }
		
    if let cstr = apr_dbd_get_entry(driverHandle, row, colIdx) {
      print("  \(name) = \(String(cString: cstr))")
    }
    else {
      print("  \(name) IS NULL")
    }
  }
}
