Oracle

问题 Hi All I am using spring simple JDBC template to call the oracle procedure the below are my code. The procedure create or replace PROCEDURE get_all_system_users( pi_client_code IN VARCHAR2, po_system_users OUT T_SYSTEM_USER_TAB, po_error_code OUT NUMBER, po_error_description OUT VARCHAR2) IS ctr NUMBER; sysUser SYSTEM_USER_OBJ; BEGIN ctr:=0; po_system_users:= t_system_user_tab(); end The Spring Dao class public class ManualSaleStoredProcedureDao { private SimpleJdbcCall getAllSytemUsers;

问题 UPDATE View the edits if you care to see the long original question. This is the clearer short version of the question... I need to see if GroupA (not always GroupA , this changes each loop iteration) exists in a [list,varray,temp table, whatever] of 200 or so groups. How I store those 200 groups is totally in my control. But I want to store them in a construct that lends itself to the FASTEST "existence" checking because I will have to check this list MANY times within a loop against

问题 I need to find dependencies between functions/procedures(defined inside package bodies) and tables which they use. I've tried all_dependencies but it works only on the package-level, not the inner function/procedure-level. Is there any possibilty to find this dependencies using e.g. all_source ? Thanks in advance for your help. 回答1: It is not possible to find the dependencies between procedures (in a package) and tables. There are several tools to examine dependencies. As you've already

问题 I am looking to return a table of results from an Oracle function. Using a cursor would be easiest, but the application I have to work this into will not accept a cursor as a return value. The alternative is to create a type (likely wrapped in a package) to go along with this function. However, it seems somewhat superfluous to create several types (I have 4+ functions to write) just so I can return table results. Is there an alternative that I am missing? 回答1: UPDATE: See the first comment

问题 I am new to Oracle, installed the Oracle today the 11g Express Edition. Then I installed Java SDK, and then the free Oracle SQL Developer. I connected with system account and created a username and table as defined below. I don't exactly know how Oracle works, I think instead of database name, usernames are used. So below are details. Username/Connection/Database = CustomSearch Table = Reservation_General_2 There are some columns inside that table and some data. but the point is I cant

问题 I'm working with an Oracle database. I can do this much: import pandas as pd import pandas.io.sql as psql import cx_Oracle as odb conn = odb.connect(_user +'/'+ _pass +'@'+ _dbenv) sqlStr = "SELECT * FROM customers" df = psql.frame_query(sqlStr, conn) But I don't know how to handle bind variables, like so: sqlStr = """SELECT * FROM customers WHERE id BETWEEN :v1 AND :v2 """ I've tried these variations: params = (1234, 5678) params2 = {"v1":1234, "v2":5678} df = psql.frame_query((sqlStr,params
