问题 I do a call to an oracle stored procedure using JDBCTemplate which has an in/out parameter of STRUCT. One of the fields on this struct is a VARCHAR which gets updated depending on the stored procedure logic. However when this is returned from the call it just contains three question marks - '???'. This is possibly the work of the Riddler but it sounds more like a char encoding issue. This worked fine until we switched databases to a database that had a character encoding of WE8ISO8859P15

问题 My standalone application uses Spring JDBC. I see a lot of the following statements in System.out Mar 28, 2013 6:42:12 PM org.springframework.jdbc.core.JdbcTemplate extractReturnedResults INFO: Added default SqlReturnUpdateCount parameter named #update-count-1 How do I prevent these logs? 回答1: I got around this by skipping the undeclared results, which I don't need anyway JdbcTemplate jt = new JdbcTemplate(dataSource); jt.setSkipUndeclaredResults(true); 回答2: You can write the function call in

问题 I have the following method that I use with Spring JDBC public String getState() { String stateLink = template.queryForObject( "select state_url from state_scrape_queue where in_use = false ORDER BY scrape_timestamp NULLS FIRST LIMIT 1", (result, rowNum) -> { return result.getString("state_url"); }); return stateLink; } I can't find an example of how to do a for update with Spring JDBC. I want in_use to be set to true using for update. I need to use select for update since this application

问题 I am working on developing micro services for a monolithic application using spring boot + spring cloud + spring JDBC. Currently, the application is connecting to a single database through tomcat JNDI connection pool. We have a bottleneck here, not to change the database architecture at this point of time because of various reasons like large number of db objects,tight dependencies with other systems,etc. So we have isolated the micro services based on application features. My concern is if

问题 Can anyone give me short description about his spring class org.springframework.jdbc.core.BatchPreparedStatementSetter (JavaDoc API Link) 回答1: It's used for bulk insertion of many rows at once. This code will illustrate how it's used. Take a good look at importEmployees method, and everything should become clear. 回答2: batchUpdate can be done using JdbcTemplate batchUpdate method as follows.. public int[] batchUpdate(final List<Actor> actors) { int[] updateCounts = jdbcTemplate.batchUpdate(

Is there a complete list of all timezones? 回答1: Sorry I don't have the answer to your direct

问题 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' " +

问题 What is the main difference between Spring JDBC VS JDBC? 回答1: Let me show you some simple example using JDBC: final Connection connection = ds.getConnection(); try { final Statement statement = connection.createStatement(); try { final ResultSet resultSet = statement.executeQuery("SELECT COUNT(*) FROM Orders"); try { resultSet.next(); final int c = resultSet.getInt(1); } finally { resultSet.close(); } } finally { statement.close(); } } finally { connection.close(); } It's much better when try

问题 I have tried to configure declarative transaction management within my Spring-based web application and it refuses to cooperate with me. I have two main problems: Setting defaultAutoCommit to false on our dataSource (which we need for our application) causes all queries to rollback, with or without transactions being involved. Transactions are configured and proxy classes as well as transactional methods are created, however no transactions appear to be used. The first problem is rather
