Using dynamic statements is as simple as inserting some conditional tags around the dynamic parts of your SQL. Note An alternate getter syntax exists for boolean type properties.

TransactionManager element configured for global transactions Java.

Therefore all parameters and results must be an Object at intervirw highest level. Where as iBatis is easy to develop and easy to call procedures and functions, no need to struggle for mapping and other things. NET is used to explicitly specify the database column type of the parameter to be set by this property.


The full classname or an alias must be specified. The properties can be loaded from the classpath use the resource attribute or from any valid URL use the url attribute.

A full discussion of the Java classpath is beyond the scope of this document. Here is a simple example:. This is simple indeed, but not ideal if you have a number of statements that must execute as a single unit of work i.

In each case, a parameterObject also may be passed. The jdbcType attribute Java or dbType attribute.

Supported database types for Parameter Maps and Result Maps 3. How does intterview work? This is particularly useful in development, when you might make a change to a Data Map definition and want to see it take effect without restarting a debugging session.

Mapped Statements support caching through reference to a Cache Model element.
