Direct Known Subclasses:

SqlDefaultType, SqlGenericType

public abstract class SqlMetaType
extends java.lang.Object

Method Detail

setResult

public abstract void setResult(java.lang.Object resultInstance,
                               java.lang.String attributeName,
                               java.lang.Object resultValue,
                               boolean ingoreError)
                        throws SqlRuntimeException

Initializes the attribute of the result class with output values from SQL query execution.

Parameters:

resultInstance - the instance of the result class

attributeName - the name of the attribute in the result class

resultValue - Query execution output value

ingoreError - ignore inproper output value handling

Throws:

SqlRuntimeException - in the case of any problem with output values handling

setParameter

public abstract void setParameter(org.hibernate.Query query,
                                  java.lang.String paramName,
                                  java.lang.Object inputValue,
                                  java.lang.Class<?> inputType,
                                  boolean ingoreError)
                           throws SqlRuntimeException

Bind an input value to a named query parameter.

Parameters:

query - the object-oriented representation of a Hibernate query

paramName - the name of the parameter

inputValue - the possibly-null parameter value, a dynamic input value

ingoreError - ignore inproper input value handling

Throws:

SqlRuntimeException - in the case of any problem with input values handling
