This article shows you how to iBATIS.NET multi-parameter SQL statement configuration, the content is concise and easy to understand, absolutely can make your eyes bright, through the detailed introduction of this article, I hope you can get something.

As I am not very proficient in iBATIS.NET, but also in learning while working practice, so the iBATIS.NET series of articles will not have a certain degree of consistency

These articles should be the accumulation of some knowledge about iBATIS.NET that I usually have. Let's get to the point:

When we use iBATIS.NET to manipulate data, we are sure to encounter SQL statement parameters

When we have a parameter, the XML mapping file for iBATIS is as follows:

< statement id= "getProduct" parameterClass= "System.Int32" > select * from PRODUCT where PRD_ID = # value# < / statement >

When we have multiple parameters, the XML is as follows:

< statement id= "getProduct" parameterClass= "System.Collections.IDictionary" > select * from PRODUCT where PRD_CAT_ID = # catId# and PRD_CODE = # code# < / statement >

A Hashtable must be assigned to him in the code, and the Hashtable has two keys, catId and code, so be careful to be case-sensitive.

When we execute the stored procedure, the xml is as follows:

First define the parameter definition set

< parameterMaps > < parameterMap id= "insertperson" class= "Person" > < parameter property= "FirstName" column= "PER_FIRST_NAME" / > < parameter property= "LastName" column= "PER_LAST_NAME" / > < / parameterMap > < / parameterMaps >

Then define the operation
