方法详细资料

sqlType

int sqlType()

toString

String toString(T value)
         throws HibernateException

抛出:

HibernateException

fromStringValue

T fromStringValue(String xml)
           throws HibernateException

抛出:

HibernateException

nullSafeGet

T nullSafeGet(ResultSet rs,
              String name,
              SharedSessionContractImplementor session)
       throws HibernateException,
              SQLException

Get a column value from a result set by name.

参数:

rs - The result set from which to extract the value.

name - The name of the value to extract.

session - The session from which the request originates

返回:

The extracted value.

抛出:

HibernateException - Generally some form of mismatch error.

SQLException - Indicates problem making the JDBC call(s).

get

Object get(ResultSet rs,
           String name,
           SharedSessionContractImplementor session)
    throws HibernateException,
           SQLException

Get a column value from a result set, without worrying about the possibility of null values.

参数:

rs - The result set from which to extract the value.

name - The name of the value to extract.

session - The session from which the request originates

返回:

The extracted value.

抛出:

HibernateException - Generally some form of mismatch error.

SQLException - Indicates problem making the JDBC call(s).

set

void set(PreparedStatement st,
         T value,
         int index,
         SharedSessionContractImplementor session)
  throws HibernateException,
         SQLException

Set a parameter value without worrying about the possibility of null values. Called from Type.nullSafeSet(java.sql.PreparedStatement, java.lang.Object, int, boolean[], org.hibernate.engine.spi.SharedSessionContractImplementor) after nullness checks have been performed.

参数:

st - The statement into which to bind the parameter value.

value - The parameter value to bind.

index - The position or index at which to bind the param value.

session - The session from which the request originates

抛出:

HibernateException - Generally some form of mismatch error.

SQLException - Indicates problem making the JDBC call(s).
