I am using the Spring NamedParameterJdbcTemplate to fetch some values from a table. For some reason, the query runs very slow in my Java app as opposed to running the same query on SQL Management Studio. I also noticed in the profiler, the prepared statements don't get reused. If I run the same query in my JAVA app multiple times, I see different prepared statements being executed. So, not sure why the statements are not getting reused. Is the performance slow because I am using a IN clause in my query? Here is my sample java code StringBuilder vQuery = new StringBuilder(); vQuery.append("

I cannot figure out why I am getting "Invalid column name" here. We have tried a variant of the sql directly in Oracle, and it works fine, but when I try it using jdbcTemplate then something is wrong. List<Dataholder> alleXmler = jdbcTemplate.query("select p.applicationid, x.datadocumentid, x.datadocumentxml " + "from CFUSERENGINE51.PROCESSENGINE p " + "left join CFUSERENGINE51.DATADOCUMENTXML x " + "on p.processengineguid = x.processengineguid " + "where x.datadocumentid = 'Disbursment' " + "and p.phasecacheid = 'Disbursed' ", (rs, rowNum) -> { return Dataholder.builder() .applicationid(rs

Is there Java library like Spring JDBC Template, with same quality of code and documentation and similar data access exceptions hierarchy , but without dependancies on other Spring modules (core/beans/context modules according to http://mvnrepository.com/artifact/org.springframework/spring-jdbc/3.0.6.RELEASE )? Spring-jdbc has direct dependency to the following libraries: spring-core , spring-beans and spring-tx . The rest of the dependencies are optional, so you don't need them actually. If these dependencies are already a lot for you, then you might have a look at Apache DbUtils . A minor

I am developing springboot-springsession-jdbc-demo . When I simply run the code I get the following error. It looks to me some property must need to set in application.properties in order create the schema/tables before hand. Required configuration is already in placed and still it gives error. The code is present in https://github.com/sivaprasadreddy/spring-session-samples The error for reference: org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [DELETE FROM SPRING_SESSION WHERE LAST_ACCESS_TIME < ?]; nested exception is com.mysql.jdbc.exceptions

How to use ResultSetExtractor to retrieve data from database? here I am using oracle 10g as back end. In case of searching an Employee details from Employee Table which one is better to use ResultSetExtractor or RowMapper ? One can also use closures (lambdas) as row mapping routine since java 8: String sql = "select first_name, last_name from PERSON where id = ?"; public Person jdbcTemplate.query(sql,(rs)->{return new Person(rs.getString("first_name"), rs.getString("last_name"));}, int id); First method param is your query, second - your mapper - Person(String, String) constructor is needed.
