bind

public int bind(PreparedStatement statement,
                QueryParameters qp,
                SharedSessionContractImplementor session,
                int start)
         throws SQLException

从接口复制的说明: ParameterBinder

Bind the appropriate value into the given statement at the specified position.

指定者:

bind 在接口中 ParameterBinder

参数:

statement - The statement into which the value should be bound.

qp - The defined values for the current query execution.

session - The session against which the current execution is occuring.

start - The position from which to start binding value(s).

返回:

The number of sql bind positions "eaten" by this bind operation.

抛出:

SQLException - Indicates problems performing the JDBC bind operation.

getExpectedType

public Type getExpectedType()

从接口复制的说明: ParameterSpecification

Get the type which we are expecting for a bind into this parameter based on translated contextual information.

指定者:

getExpectedType 在接口中 ParameterSpecification

返回:

The expected type.

setExpectedType

public void setExpectedType(Type expectedType)

从接口复制的说明: ParameterSpecification

Injects the expected type. Called during translation.

指定者:

setExpectedType 在接口中 ParameterSpecification

参数:

expectedType - The type to expect.

renderDisplayInfo

public String renderDisplayInfo()

从接口复制的说明: ParameterSpecification

Render this parameter into displayable info (for logging, etc).

指定者:

renderDisplayInfo 在接口中 ParameterSpecification

返回:

The displayable info.
