In the recent release of iBatisnet1.5, the major change was to support some features of. NET 2.0. After the update, some new changes are also found:
1. the detection of configuration files is more rigorous. After the update, you will find that errors may occur in the original version, but errors will not be detected due to unused configuration sections, an error is prompted during the initialization of the new version.
2. I used selectKey in this way.
<SelectKey property = "FID" resultClass = "int" type = "post">
SELECT @ identity as # value #
</SelectKey>
Although the "#" number should not be added before and after the value, such configuration may be correctly executed in the original version (no errors will occur in the past ). However, in the new version, an empty reference exception occurs. The result of troubleshooting is that "#" is added before and after the value. If you want to use it like this, pay special attention to where the value keyword needs to be added "#" and where it does not need to be added
