Static Imports
org.jooq.SQLDialect.FIREBIRD, org.jooq.impl.ClobBinding.NO_SUPPORT_NULL_LOBS, .DefaultExecuteContext.localConnection, .DefaultExecuteContext.localTargetConnection, .Tools.asInt
A binding that takes binary values but binds them as Blob to at the JDBC level.

This is useful for workarounds for bugs in Oracle, like ORA-01461: can bind a LONG value only for insert into a LONG column (see [#4091])

sqlback to summary
public final void sql(BindingSQLContext<byte[]> ctx) throws SQLException

Implements org.jooq.Binding.sql.

Doc from org.jooq.Binding.sql.

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.

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

Parameters
ctx:BindingSQLContext<byte[]>

The context object containing all argument objects.
