CallableStatement or Statement interfaces. Updated the post to include the code. You can add it as a build dependency or add to your local maven repo and use it as a maven dependency. Spring boot further simplifies the code by configuring Spring automatically wherever possible. DBCP avoids some complexity which can be introduced by other connection pool managers.

We are using RowCallbackHandler as we shall be processing the rows immediately. CommandLineRunner ; import org. Here I am handling only the SQLException s and masking all the others – which generally is not a good practice.

Still have no luck with PreparedStatement execution though.

That is, you cannot open a connection, explicitly begin a transaction, issue a series of separate queries within that transaction and finally roll back or commit the transaction. Evn when I try selection queries with aggregation functions, I use to get similar error. There is no significant udbc in performance between using the!

Kcb practice, this means that any single query or sequence of queries if executed in a single JDBC call will be executed in isolation without noticing the effects of other queries, and modifications made to the database will always be permanent.

I have tried to execute that as well, but the error still remains the same. ResultSet ; import mdbc. By using our site, kvb acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

The implementation builds on the lower-level javakdb APIwhich is somewhat simpler, and a kdg choice for application development when support for legacy code is not a consideration. ResultSetStatement ,! You can add it as a build dependency or add to your local maven repo and use it as a maven dependency.

IOException ; import java. In my case, using native API in not an jxbc, unfortunately. If little work is being performed per interaction via the JDBC driver, that is, few queries and each query is very quick to execute, then there is a significant advantage to using connection pooling. But whenever I try to run other queries, then the code gives me error, for example, for the following code: You can find the complete project here.

InputStreamReader ; import java. DBCP avoids some complexity which can be introduced by other connection pool managers.

It is the complete stack trace. Spring boot further simplifies the code by configuring Spring automatically wherever possible. I am able to execute the following code to select all the data from the table: JdbcTemplate ; import kcb.

I am going to use the first approach. To summarize, I am able to do only simple selection of data and nothing else.

Connection pooling Jbdc little work is being performed per interaction via the JDBC driver, that is, few queries and each query is very quick to execute, then there is a significant advantage to using connection pooling. Furthermore it offers configuration options to check the status of connections in the connection pool using a variety of strategies.
