Interface Routine<T>

All Superinterfaces:

QueryPart, Serializable

All Known Implementing Classes:

AbstractRoutine

public interface Routine<T>
extends QueryPart

A routine is a callable object in your RDBMS.

Callable objects are mainly stored procedures and stored functions. The distinction between those two object types is very subtle and not well defined across various RDBMS. In general, this can be said:

Procedures:

• Are called as callable statements
• Have no return value
• Support OUT parameters

Functions

• Can be used in SQL statements
• Have a return value
• Don't support OUT parameters

But there are exceptions to these rules:

• DB2, H2, and HSQLDB don't allow for JDBC escape syntax when calling functions. Functions must be used in a SELECT statement
• H2 only knows functions (without OUT parameters)
• Oracle functions may have OUT parameters
• Oracle knows functions that mustn't be used in SQL statements
• Oracle parameters can have default values (to support this, jOOQ renders PL/SQL instead of the JDBC escape syntax)
• Postgres only knows functions (with all features combined)
• The Sybase JDBC driver doesn't handle null values correctly when using the JDBC escape syntax on functions
• etc...

Hence, with #852, jOOQ 1.6.8, the distinction between procedures and functions becomes obsolete. All stored routines are simply referred to as "Routine".

Method Detail

getSchema

Schema getSchema()

Get the routine schema

getName

String getName()

The name of this routine

getPackage

Package getPackage()

The container package of this stored procedure or function.

This is only supported in the SQLDialect.ORACLE dialect.

Returns:

The container package of this object, or null if there is no such container.

getReturnParameter

Parameter<T> getReturnParameter()

The parameter representing this routine's getReturnValue()

Returns:

The return parameter or null if this routine doesn't have a return value.

See Also:

getParameters()

getOutParameters

List<Parameter<?>> getOutParameters()

A list of OUT parameters passed to the stored procedure as argument. This list contains all parameters that are either OUT or INOUT in their respective order of appearance in getParameters().

Returns:

The list of out parameters

See Also:

getParameters()

getInParameters

List<Parameter<?>> getInParameters()

A list of IN parameters passed to the stored procedure as argument. This list contains all parameters that are either IN or INOUT in their respective order of appearance in getParameters().

Returns:

The list of in parameters

See Also:

getParameters()

getParameters

List<Parameter<?>> getParameters()

Returns:

A list of parameters passed to the stored object as argument

execute

int execute(Configuration configuration)
     throws DataAccessException

Execute the stored object using a Configuration object

Throws:

DataAccessException - if something went wrong executing the query

execute

int execute()
     throws DataAccessException

Execute the stored object on an underlying connection

Throws:

DataAccessException - if something went wrong executing the query

setValue

<Z> void setValue(Parameter<Z> parameter,
                  Z value)

Set the routine's IN value for an IN parameter.

set

<Z> void set(Parameter<Z> parameter,
             Z value)

Set the routine's IN value for an IN parameter.

getValue

<Z> Z getValue(Parameter<Z> parameter)

Returns:

The routine's OUT value for an OUT parameter.

get

<Z> Z get(Parameter<Z> parameter)

Returns:

The routine's OUT value for an OUT parameter.

getReturnValue

T getReturnValue()

Returns:

The routine's return value (if it is a function)

getResults

Results getResults()

Returns:

The routine's results (if available)
