OdbcParameterMetaData

classin packageklyn.databases.sql.odbc

public class OdbcParameterMetaData implements ParameterMetaData:

All Implemented Interfaces: ParameterMetaData

Parameter metadata for ODBC prepared statements.

ODBC drivers do not all expose parameter descriptors consistently, so this implementation reports the parameter count known from the SQL text and uses the values bound through the Klyn API to infer type information.

import klyn.databases.sql

# prepared = connection.prepared("select * from users where id = ?")
# print(prepared.parameterInfo.parameterCount)
