  - get
```
public static ValueResultSet get(ResultSet rs)
```
    Create a result set value for the given result set. The result set will be wrapped.
    
    参数:
    
    rs - the result set
    
    返回:
    
    the value
  - getCopy
```
public static ValueResultSet getCopy(ResultSet rs,
                                     int maxrows)
```
    Create a result set value for the given result set. The result set will be fully read in memory. The original result set is not closed.
    
    参数:
    
    rs - the result set
    
    maxrows - the maximum number of rows to read (0 to just read the meta data)
    
    返回:
    
    the value
  - getType
```
public int getType()
```
    从类复制的说明: Value
    
    Get the value type.
    
    指定者:
    
    getType 在类中 Value
    
    返回:
    
    the type
  - getPrecision
```
public long getPrecision()
```
    从类复制的说明: Value
    
    Get the precision.
    
    指定者:
    
    getPrecision 在类中 Value
    
    返回:
    
    the precision
  - getDisplaySize
```
public int getDisplaySize()
```
    从类复制的说明: Value
    
    Get the display size in characters.
    
    指定者:
    
    getDisplaySize 在类中 Value
    
    返回:
    
    the display size
  - getString
```
public String getString()
```
    从类复制的说明: Value
    
    Get the value as a string.
    
    指定者:
    
    getString 在类中 Value
    
    返回:

  - compareSecure
```
protected int compareSecure(Value v,
                            CompareMode mode)
```
    从类复制的说明: Value
    
    Compare the value with another value of the same type.
    
    指定者:
    
    compareSecure 在类中 Value
    
    参数:
    
    v - the other value
    
    mode - the compare mode
    
    返回:
    
    0 if both values are equal, -1 if the other value is smaller, and 1 otherwise
  - equals
```
public boolean equals(Object other)
```
    从类复制的说明: Value
    
    Check if the two values have the same hash code. No data conversion is made; this method returns false if the other object is not of the same class. For some values, compareTo may return 0 even if equals return false. Example: ValueDecimal 0.0 and 0.00.
    
    指定者:
    
    equals 在类中 Value
    
    参数:
    
    other - the other value
    
    返回:
    
    true if they are equal
  - hashCode
```
public int hashCode()
```
    指定者:
    
    hashCode 在类中 Value
  - getObject
```
public Object getObject()
```
    从类复制的说明: Value
    
    Get the value as an object.
    
    指定者:
    
    getObject 在类中 Value
    
    返回:
    
    the object
  - getResultSet
```
public ResultSet getResultSet()
```
    覆盖:
    
    getResultSet 在类中 Value
  - set
```
public void set(PreparedStatement prep,

```
    从类复制的说明: Value
    
    Set the value as a parameter in a prepared statement.
    
    指定者:
    
    set 在类中 Value
    
    参数:
    
    prep - the prepared statement
    
    parameterIndex - the parameter index
  - getSQL
```
public String getSQL()
```
    从类复制的说明: Value
    
    Get the SQL expression for this value.
    
    指定者:
    
    getSQL 在类中 Value
    
    返回:
    
    the SQL expression
  - convertPrecision
```
public Value convertPrecision(long precision,
                              boolean force)
```
    从类复制的说明: Value
    
    Convert the precision to the requested value. The precision of the returned value may be somewhat larger than requested, because values with a fixed precision are not truncated.
    
    覆盖:
    
    convertPrecision 在类中 Value
    
    参数:
    
    precision - the new precision
    
    force - true if losing numeric precision is allowed
