Retrieving only the required data can reduce the size of data retrieved. For example, do not issue the following: select * from emp_table where ... If you just need the id and name, then issue the following: select id, name from emp_table where ... You should return only the rows you need. If you return ten columns when you need only two columns, you will get decreased performance, especially if the unnecessary rows include long data. Another way to reduce network traffic and improve your application performance is to reduce the size of any data being retrieved to some manageable limit by calling driver-specific methods: Statement.setMaxRows(int max): Sets the limit for the maximum number of rows that any ResultSet object can contain to the given number. If the limit is exceeded, the excess rows are silently dropped. Statement.setMaxFieldSize(): Sets the limit for the maximum number of bytes in a ResultSet column storing character or binary values to the given number of bytes. This limit applies only to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, and LONGVARCHAR fields. If the limit is exceeded, the excess data is silently discarded. For maximum portability, use values greater than 256. ResultSet.setFetchSize(int max): Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed for this ResultSet object. Statement.setFetchSize(int max): Gives the JDBC driver a hint as to the number of rows that should be fetched from the database. Another method of reducing the size of the data being retrieved is to decrease the column size. You can accomplish this by defining an optimized schema. For example, if the driver allows you to define the packet size, use the smallest packet size that will meet your needs. java code 39 generator generate code39 barcode data in java? - Stack Overflow

Generally, use the Statement object instead of the PreparedStatement object. If you plan to execute a SQL query many times with different input parameter values, then you should use the PreparedStatement object. JDBC drivers are optimized based on the perceived use of the functions being executed. Choose between the PreparedStatement object and the Statement object depending on the planned use. The Statement object is optimized for a single execution of a SQL statement. In contrast, the PreparedStatement object is optimized for SQL statements that will be executed two or more times. You should note that the overhead for the initial execution of a PreparedStatement object is high. The advantage comes with subsequent executions of the SQL statement. java qr code reader webcam, .net code 39 reader, asp.net code 39 reader, barcode code 39 word, vb.net ean 13 reader, asp.net code 39 code 39 barcode generator java Code 39 Barcode Generator for Java
