Build 22.0.8388

Procedures

Procedures

A system table called "sys_procedures" is queried to obtain the available stored procedures that are executed:

import cdata.adls as mod
conn = mod.connect("Schema=ADLSGen2;Account=MyStorageAccount;FileSystem=MyBlobContainer;AccessKey=myAccessKey;")
cur = conn.cursor()
cmd = "SELECT * FROM sys_procedures"
cur.execute(cmd)
rs = cur.fetchall()
for row in rs:
	print(row)

Parameters

The input parameters of any stored procedure are similarly obtained from the "sys_procedureparameters" system table:

import cdata.adls as mod
conn = mod.connect("Schema=ADLSGen2;Account=MyStorageAccount;FileSystem=MyBlobContainer;AccessKey=myAccessKey;")
cur = conn.cursor()
cmd = "SELECT * FROM sys_procedureparameters WHERE ProcedureName = 'DownloadFile'"
cur.execute(cmd)
rs = cur.fetchall()
for row in rs:
	print(row)
