Package dev.frostlake.jdbc

Class JdbcParameterMetaData

java.lang.Object

dev.frostlake.jdbc.JdbcParameterMetaData

All Implemented Interfaces:

ParameterMetaData, Wrapper

public class JdbcParameterMetaData
extends Object
implements ParameterMetaData

Minimal ParameterMetaData for the engine's PreparedStatements: reports the placeholder count. Per-parameter types are generic (OTHER) because parameters are inlined client-side as SQL literals (there is no server-side bind that would carry a declared type).
