StatementUtil() |
| Modifier and Type | Method and Description |
|---|---|
static <T> T |
executeQuery(PreparedStatement ps,
RsHandler<T> rsh)
执行查询
|
static int |
executeUpdate(PreparedStatement ps,
Object... params)
用于执行 INSERT、UPDATE 或 DELETE 语句以及 SQL DDL(数据定义语言)语句,例如 CREATE TABLE 和 DROP TABLE。
|
static PreparedStatement |
fillArrayParam(PreparedStatement ps,
Object... params)
填充SQL的参数。
|
static PreparedStatement |
fillParams(PreparedStatement ps,
Iterable<?> params)
填充SQL的参数。
|
static PreparedStatement |
fillParams(PreparedStatement ps,
Iterable<?> params,
Map<Integer,Integer> nullTypeCache)
填充SQL的参数。
|
static Long |
getGeneratedKeyOfLong(Statement ps)
获得自增键的值
此方法对于Oracle无效(返回null) |
static List<Object> |
getGeneratedKeys(Statement ps)
获得所有主键
|
static <T> T |
getGeneratedKeys(Statement statement,
RsHandler<T> rsHandler)
获取主键,并使用
RsHandler 处理后返回 |
static int |
getTypeOfNull(PreparedStatement ps,
int paramIndex)
获取null字段对应位置的数据类型
有些数据库对于null字段必须指定类型,否则会插入报错,此方法用于获取其类型,如果获取失败,使用默认的 Types.VARCHAR |
