Reusing a PreparedStatement

I ran findbugs on our code base and it pointed out there are two more Statements that still need to be closed. In this section of the code we run: preparedStatement = connection.prepareStatement(query); for 3 different queries, reusing preparedStatement. In the finally block we do close the resource: finally{ try{ if (resultSet != null) resultSet.close(); } catch (Exception e) { exceptionHandler.ignore(e); } try { if (preparedStatement != null) preparedStatement.close(); } catch(Exception e) { exceptionHandler.ignore(e); } Should the statement be closed before the next connection

Execute NHibernate-generated prepared statements in SQL Server Management Studio

由 丶灬走出姿态 提交于 2019-12-01 08:15:01
Configuring NHibernate to display executed SQL does what it's supposed to, but whenever a SQL string needs to be copy-pasted into SQL Server Management Studio, we have to rearrange it dramatically in order to be compatible. Before I dive into developing my own application that parses and rearranges this into a more ManagementStudio-friendly SQL, I'd like to reassert that this hasn't been done before - I'd hate to spend time on this and find out later. Is there a cheap and practicable way of converting the NH-generated prepared statement into something that's executable straight away? Thanks in

CREATE DATABASE query using java jdbc and prepared statement returns syntax error

由 旧街凉风 提交于 2019-12-01 06:31:50
问题 I am trying to get Java to create a database using JDBC but I get a syntax error, despite the query being correct. If I write the name of a database into the code explicitly, for example, it works fine. Here's my code: package mysql_manipulator; import java.sql.Connection; import java.sql.DriverManager; import java.sql.PreparedStatement; public class Create { private static final String driver = "com.mysql.jdbc.Driver", url = "jdbc:mysql://localhost", username = "dylan", password = "******";

QSqlQuery prepared statements - proper usage

由 爷，独闯天下 提交于 2019-12-01 05:51:59
问题 I'm trying to determine the proper way to use prepared statements with QSqlQuery. The docs are not very specific on this subject. void select(const QSqlDatabase &database) { QSqlQuery query(database); query.prepare("SELECT * FROM theUniverse WHERE planet = :planet"); query.bindValue(":planet", "earth"); query.exec(); } So will this snippet create a permanent prepared statement in the connection database ? Will this prepared statement persist between calls to select() , i.e. will it be saved

问题 Mysql supports prepared statements in this way: http://dev.mysql.com/doc/refman/5.0/en/sql-syntax-prepared-statements.html Is there a support for it in Zend Framework (I couldn't find it), and how to use it.

Parameterised IN Clause in prepared statement using MySql,PHP and ADODB

由 穿精又带淫゛_ 提交于 2019-12-01 05:19:35
问题 I am writing some SQL and using AdoDb to connect to my database and run the queries and so on. I am using parametrized queries and have run into a snag. Is their a way to pass an array of values to an in_clause in AdoDb/MySql for parametrization. My problem is that if I pass a prepared string as the parameter i.e. 'test','test2','test3' it does not work as the library or database auto escapes it and adds external quotes at the start and end so all the internal quotes are then auto escaped

batch preparedstatement with different sql queries

由 三世轮回 提交于 2019-12-01 05:12:06
I found existing questions similar to this one that did not actually have a clear answer to the question. A normal batch preparedstatement with one sql query would look something like this: private static void batchInsertRecordsIntoTable() throws SQLException { Connection dbConnection = null; PreparedStatement preparedStatement = null; String insertTableSQL = "INSERT INTO DBUSER" + "(USER_ID, USERNAME, CREATED_BY, CREATED_DATE) VALUES" + "(?,?,?,?)"; try { dbConnection = getDBConnection(); preparedStatement = dbConnection.prepareStatement(insertTableSQL); dbConnection.setAutoCommit(false);
