Procedures

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

import cdata.googlespanner as mod
conn = mod.connect("ProjectId='project1';InstanceId='instance1';Database='db1';OAuthClientId='757060765381';OauthClientSecret='abc';")
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.googlespanner as mod
conn = mod.connect("ProjectId='project1';InstanceId='instance1';Database='db1';OAuthClientId='757060765381';OauthClientSecret='abc';")
cur = conn.cursor()
cmd = "SELECT * FROM sys_procedureparameters WHERE ProcedureName = 'SelectEntries'"
cur.execute(cmd)
rs = cur.fetchall()
for row in rs:
	print(row)
