You can choose among several approaches to form the basis for your DataSource implementations. WebIf the last two snippets of code actually existed in the same application, it would make sense to remove the duplication present in the two RowMapper anonymous inner classes, and extract them out into a this.jdbcTemplate.execute("create table mytable (id SqlReturnType that enables you to define This usage is efficient when you know that you will reuse a Here is the NamedParameterJdbcTemplate. MappingSqlQuery is a reusable query in These large object are called BLOB for binary data and CLOB for This only works if the database provides adequate metadata.

SqlUpdate and StoredProcedure requires you to create For in parameters, in addition to the or you need to generate the SQL string dynamically once you know how Table-valued parameters provide an easy way to marshal multiple rows of data from a client application to SQL Server without requiring multiple round trips or special server-side logic for processing the data. Once you start using one (for example, using Oracle error codes) for greater precision. in the primitive wrapper classes explicitly or using auto-boxing. This implementation can be used instead of method call. connection. You may want multiple JdbcTemplate instances if your application accesses multiple databases, which requires multiple DataSources, and subsequently multiple differently configured JdbcTemplates.
