问题 I have PL/SQL table-type and procedure as below. It is just part of code. While populating PL/SQL table type variable I am getting exception. CREATE OR REPLACE TYPE OBJ_EMPLOYEE AS OBJECT ( EMPID NUMBER(12) , EMPLOYEENAME VARCHAR2(100) , /* more attributes */ STATUS VARCHAR2(20) , UPDTDATE DATE , ); CREATE OR REPLACE TYPE TAB_EMPLOYEE IS TABLE OF OBJ_EMPLOYEE; CREATE OR REPLACE PROCEDURE sp_getEmpDetails ( p_ErrorCode_o OUT VARCHAR2, p_ErrorMsg_o OUT VARCHAR2 ) IS TEMP_EMPLOYEE TAB_EMPLOYEE :

问题 This question already has an answer here : Oracle get checksum value for a data chunk defined by a select clause (1 answer) Closed 2 years ago . We need to be able to compute table hashes for an external environment and compare it to pre-computed hash from an internal environment. The use of this is to ensure that data in the external environment is not tampered by a "rogue" database administrator. Users insist this feature . Currently, we do this by computing the individual hashes of each

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 have a table with many partitions range. I need to get the name of all partition when I give a date. For eg: if I input date 20/09/2014, it should list all partitions before that given date. create or replace function get_part_name(p_date in date) return varchar2 is d date; retp varchar2(30); mind date:=to_date('4444-01-01','yyyy-mm-dd'); str varchar2(32000); cursor c is select high_value, partition_name p from user_tab_partitions where table_name='TEST'; begin for r in c loop str := r.high

问题 I want to write a SQL query which accepts a bind variable (say :NUM) and its output consists of one column & :NUM number of rows, each row having its row number. i.e. if we pass :NUM as 7, the output should be: VAL ==== 1 2 3 4 5 6 7 There shouldn't be any actual DB tables in query and no PL/SQL code should be used. i.e. only dual should be used in the query Is there any way to achieve this? 回答1: You could use: WHERE ROWNUM <= :NUM ...but the table has to contain row equal or greater to the
