Mapping JDBC Types to Java Types (SAP Library - SAP NetWeaver Composition Environment Library)

Mapping JDBC Types to Java Types

The conceptual mapping between JDBC types and Java types is shown in the following table. The Open SQL programmer should consider this mapping when writing code. For example, if a value in the database is SMALLINT, a short should be the data type used as output or input host variable of a SQL statement.
