public void sql(BindingSQLContext<U> ctx)
Binding
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.RenderContext.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
.RenderContext.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)
