IProcedure

Comments

When a new procedure is created, to ensure its correct work, determine the following minimum set of properties in the settings:

To execute the procedure and get results, open the repository object using the IMetabaseObjectDescriptor.Open or IMetabaseObjectDescriptor.OpenWithParam method and cast it to the ISQLCommandInstance interface. If procedure is parametric, the set of parameters for opening can be created using the IMetabaseObjectParams.CreateEmptyValues method. Parameters with the Output or Function Result type will be available in created set of parameters after executing the ISQLCommandInstance.Execute method.

On creating the Procedure object in repository, the stored procedure/function will be created on DBMS server. It can be also used with the DAL assembly resources, the example of use is given in theExecuting Stored Procedures and Functions article.

NOTE. On executing a big number of procedures and procedures with output parameters, it is recommended to use the DAL assembly resources and not the ISQLCommandInstance interface.
