Procedures
Procedures
A system table called "sys_procedures" is queried to obtain the available stored procedures that are executed:import cdata.presto as mod conn = mod.connect("Server=127.0.0.1;Port=8080;") 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.presto as mod conn = mod.connect("Server=127.0.0.1;Port=8080;") cur = conn.cursor() cmd = "SELECT * FROM sys_procedureparameters WHERE ProcedureName = 'CreateTable'" cur.execute(cmd) rs = cur.fetchall() for row in rs: print(row)
