方法详细资料

prepare

void prepare(CallableStatement statement,
             int i)
      throws SQLException

Prepare for execution.

参数:

statement - The statement about to be executed

i - The parameter index for this registration (used for positional)

抛出:

SQLException - Indicates a problem accessing the statement object

getHibernateType

Type getHibernateType()

Access to the Hibernate type for this parameter registration

指定者:

getHibernateType 在接口中 QueryParameter<T>

返回:

The Hibernate Type

isPassNullsEnabled

boolean isPassNullsEnabled()

If no value is bound for this parameter registration, is the passing of NULL to the JDBC CallableStatement for that parameter enabled? This effectively controls whether default values for the argument as defined in the database are applied or not.

指定者:

isPassNullsEnabled 在接口中 ProcedureParameter<T>

返回:

true indicates that NULL will be passed to the JDBC driver, effectively disabling the application of the default argument value defined in the database; false indicates that the parameter will simply be ignored, with the assumption that the corresponding argument defined a default value.

isPassNullsEnabled()

getSqlTypes

int[] getSqlTypes()

Access to the SQL type(s) for this parameter

返回:

The SQL types (JDBC type codes)

extract

T extract(CallableStatement statement)

Extract value from the statement after execution (used for OUT/INOUT parameters).

参数:

statement - The callable statement

返回:

The extracted value
