@Deprecated(forRemoval=true)
public DefaultBinding(Converter<T,U> converter)

Deprecated, for removal: This API element is subject to removal in a future version.

- 3.11 - [#6631] - Use binding(Converter) instead.

DefaultBinding

public DefaultBinding(Binding<T,U> delegate)

Method Details

binding

public static final <T,
U> Binding<T,U> binding(Converter<T,U> converter)

Get the internal default binding for a Converter.

binding

public static final <T> Binding<T,T> binding(DataType<T> dataType)

Get the internal default binding for a DataType.

converter

public Converter<T,U> converter()

Description copied from interface: Binding

A converter that can convert between the database type and the custom type.

While the Converter property of a binding is not optional (Converter.fromType() and Converter.toType() are needed by jOOQ's internals), the conversion implementation (i.e. Converter.from(Object) and Converter.to(Object)) isn't strictly required if implementations don't rely on it. If these conversion implementations are non-functional, it is advised to hint at this fact in Converter.fromSupported() and Converter.toSupported().

Specified by:

converter in interface Binding<T,U>

sql

public void sql(BindingSQLContext<U> ctx)
         throws SQLException

Description copied from interface: Binding

Generate SQL code for the bind variable.

Implementations should generate SQL code onto BindingSQLContext.render(), given the context's bind variable located at BindingSQLContext.value(). Examples of such SQL code are:

• "?": Default implementations can simply generate a question mark.
  
  
• "123": Implementations may choose to inline bind variables to influence execution plan generation.
  
  Context.paramType() contains information whether inlined bind variables are expected in the current context.
  
  
• "CAST(? AS DATE)": Cast a database to a more specific type. This can be useful in databases like Oracle, which map both DATE and TIMESTAMP SQL types to Timestamp.
  
  Context.castMode() may contain some hints about whether casting is suggested in the current context.
  
  
• "?::json": Vendor-specific bind variables can be supported, e.g. SQLDialect.POSTGRES's JSON data type.

Implementations must provide consistent behaviour between Binding.sql(BindingSQLContext) and Binding.set(BindingSetStatementContext), i.e. when bind variables are inlined, then they must not be bound to the PreparedStatement in Binding.set(BindingSetStatementContext)

Specified by:

sql in interface Binding<T,U>

Parameters:

ctx - The context object containing all argument objects.

Throws:

SQLException - Implementations are allowed to pass on all SQLExceptions to the caller to be wrapped in DataAccessExceptions.

register

public void register(BindingRegisterContext<U> ctx)
              throws SQLException

Description copied from interface: Binding

Register a CallableStatement's OUT parameter.

Specified by:

register in interface Binding<T,U>

Parameters:

ctx - The context object containing all argument objects.

Throws:

SQLException - Implementations are allowed to pass on all SQLExceptions to the caller to be wrapped in DataAccessExceptions.

set

public void set(BindingSetStatementContext<U> ctx)
         throws SQLException

Description copied from interface: Binding

Set a PreparedStatement's IN parameter.

Specified by:

set in interface Binding<T,U>

Parameters:

ctx - The context object containing all argument objects.

Throws:

SQLException - Implementations are allowed to pass on all SQLExceptions to the caller to be wrapped in DataAccessExceptions.

set

public void set(BindingSetSQLOutputContext<U> ctx)
         throws SQLException

Description copied from interface: Binding

Set a SQLOutput's IN parameter.

Specified by:

set in interface Binding<T,U>

Parameters:

ctx - The context object containing all argument objects.

Throws:

SQLException - Implementations are allowed to pass on all SQLExceptions to the caller to be wrapped in DataAccessExceptions.

get

public void get(BindingGetResultSetContext<U> ctx)
         throws SQLException

Description copied from interface: Binding

Get a ResultSet's OUT value.

Implementations are expected to produce a value by calling BindingGetResultSetContext.value(Object), passing the resulting value to the method.

Specified by:

get in interface Binding<T,U>

Parameters:

ctx - The context object containing all argument objects.

Throws:

SQLException - Implementations are allowed to pass on all SQLExceptions to the caller to be wrapped in DataAccessExceptions.

get

public void get(BindingGetStatementContext<U> ctx)
         throws SQLException

Description copied from interface: Binding

Get a CallableStatement's OUT value.

Implementations are expected to produce a value by calling BindingGetStatementContext.value(Object), passing the resulting value to the method.

Specified by:

get in interface Binding<T,U>

Parameters:

ctx - The context object containing all argument objects.

Throws:

SQLException - Implementations are allowed to pass on all SQLExceptions to the caller to be wrapped in DataAccessExceptions.

get

public void get(BindingGetSQLInputContext<U> ctx)
         throws SQLException

Description copied from interface: Binding

Get a SQLInput's OUT value.

Implementations are expected to produce a value by calling BindingGetSQLInputContext.value(Object), passing the resulting value to the method.

Specified by:

get in interface Binding<T,U>

Parameters:

ctx - The context object containing all argument objects.

Throws:

SQLException - Implementations are allowed to pass on all SQLExceptions to the caller to be wrapped in DataAccessExceptions.
