mytable values (1, ' abc ') INSERT INTO mytable values (2, ' Def ') And so on, it is advisable to change to a statement with a parameter tag that is prepared and executed repeatedly. INSERT INTO mytable values (?,?) Using parameter markers allows a series of inserts to run more than a few times faster. (using host variables in a static SQL program can also achieve similar benefits.) ) 2. Send column values to the server There are several types of optimization techniques that can be attributed t

the most common techniques that the optimizer uses to design DB2 access paths. Among the many decisions that the optimizer must make, the most important decision may be whether to use an index to implement the query. Before the optimizer makes this decision, it must first determine whether an index exists. Keep in mind that you can query any column in any table, but you can't expect to do this by simply indexing. Therefore, the optimizer must be abl

Fast-changing application environments require a flexible mechanism for storing data and passing data between different application tiers. As it turns out, JSON (Java Script Object notation) is an important technology for moving, interactive applications that reduces the overhead of pattern design and eliminates the need for data conversion. DB2 NoSQL JSON enables developers to write applications using the JSON-oriented popular query language created
