Method Detail

get

public X get(ResultSet rs,
             String columnLabel)
      throws SQLException

Description copied from interface: TypeHandler

从结果集里获取一个字段的值

Specified by:

get in interface TypeHandler<X>

Parameters:

rs - 结果集

columnLabel - 列名

Returns:

字段值

Throws:

SQLException

get

public X get(ResultSet rs,
             int columnIndex)
      throws SQLException

Description copied from interface: TypeHandler

从结果集里获取一个字段的值

Specified by:

get in interface TypeHandler<X>

Parameters:

rs - 结果集

columnIndex - 索引

Returns:

字段值

Throws:

SQLException

get

public X get(CallableStatement cs,
             int parameterIndex)
      throws SQLException

Specified by:

get in interface TypeHandler<X>

Throws:

SQLException

get

public X get(CallableStatement cs,
             String parameterName)
      throws SQLException

Specified by:

get in interface TypeHandler<X>

Throws:

SQLException

set

public Object set(PreparedStatement ps,
                  Object value,
                  int index)
           throws SQLException

Description copied from interface: TypeHandler

为缓冲语句设置值

一个值可以被设置到多个占位符中

Specified by:

set in interface TypeHandler<X>

Parameters:

ps - 缓冲语句

value - 值

index - 占位符位置，从 1 开始

Returns:

实际被设置到Statement中的值。

Throws:

SQLException
