Procedure Parameters
The ProcedureParameters schema collection describes the stored procedure parameters.
Retrieving Stored Procedure Parameter Metadata
The ProcedureParameters schema collection contains information about the parameters of stored procedures.
To retrieve the ProcedureParameters schema collection, call the GetSchema method of the JiraAssetsConnection class. Access the metadata in the DataTable object returned. The following example retrieves parameter information for all stored procedures:
C#
String connectionString = "User=MyUser;APIToken=myApiToken;Url=https://yoursitename.atlassian.net"; using (JiraAssetsConnection conn = new JiraAssetsConnection(connectionString)) { conn.Open(); DataTable table = conn.GetSchema("ProcedureParameters"); foreach (DataRow row in table.Rows) { foreach (DataColumn col in table.Columns) { Console.WriteLine(col.ColumnName + "=" + row[col]); } } }
VB.NET
Dim connectionString As [String] = "User=User=MyUser;APIToken=myApiToken;Url=https://yoursitename.atlassian.net" Using conn As New JiraAssetsConnection(connectionString) conn.Open() Dim table As DataTable = conn.GetSchema("ProcedureParameters") For Each row As DataRow In table.Rows For Each col As DataColumn In table.Columns Console.WriteLine(col.ColumnName + "=" + row(col)) Next Next End Using
