How can I view the code of a stored procedure using sqlplus for Oracle 10g?
When I type in:
desc daily_update;
it shows me the parameter, but when I try to do the following:
select * from all_source where name = 'daily_update';
I get
no rows selected
What am I doing wrong?
check your casing, the name is typically stored in upper case
SELECT *
FROM all_source
WHERE name = 'DAILY_UPDATE'
ORDER BY TYPE, LINE;

I'm exploring cx_Oracle's JSON features within a CLOB. I have an index on the table that allows me to query for direct equality
SELECT * FROM mytable m WHERE m.jsonclob.jsonattribute = 'foo';
I'd like to be able to do the same thing with a LIKE statement.
SELECT * FROM mytable m WHERE m.jsonclob.jsonattribute LIKE 'foo.%';
This works for me with Oracle DB 12.2:
SQL> CREATE TABLE j_purchaseorder_b (po_document CLOB CHECK (po_document IS JSON)) LOB (po_document) STORE AS (CACHE);
Table created.
SQL> INSERT INTO j_purchaseorder_b VALUES ('{"userId":2,"userName":"Bob","location":"USA"}');
1 row created.
SQL> SELECT pob.po_document.location FROM j_purchaseorder_b pob where pob.po_document.location LIKE 'US%';
LOCATION

USA
For reference check the Oracle JSON manual chapter Query JSON Data.
A side note: the JSON team like recommending BLOB for storage for performance reasons. Check the doc etc etc etc.
I want to find the name of the stored procedure, package, function or trigger which is inserting data into a particular table, is there any inbuilt object so that i can use it. I am searching the name of the object from last 2 hours. Kindly help.
You cannot find the inserted PL/SQL block, but you can try out to identify the procedures/functions referring it. And increase your chances of finding.
select
proc_syn.nam,
proc_syn.referenced_owner,
proc_syn.referenced_name,
proc_syn.referenced_type,
syn_tab.table_name
from
dba_dependencies proc_syn, dba_synonyms syn_tab, dba_tables tables
where
REFERENCED_TYPE in ( 'SYNONYM','TABLE')
AND proc_syn.referenced_name = syn_tab.synonym_name
AND syn_tab.synonym_name = tables.table_name
AND syn_tab.owner = 'PUBLIC'
AND REFERENCED_NAME = 'YOUR_TABLE_NAME'
order by
proc_syn.referenced_owner, syn_tab.table_name;
The above query would return the table objects, that refer this table.
Note, this would return, when you use STATIC queries only. Any dynamic queries, is completely out of hand.
You can try by analyzing all the source of your DB with something like this:
select *
from dba_source
where upper(text) like '%TABLE_NAME%'
The pro of this approach is that you will get even dynamic code; the con is that you'll have even select, update, ...
If the table is statically referenced you can check the ALL_DEPENDENCIES view
SELECT * FROM ALL_DEPENDENCIES WHERE REFERENCED_NAME = '<your table>';
This will find all usages, not only insert
You can also search within source code:
SELECT * FROM ALL_SOURCE WHERE UPPER(TEXT) LIKE '%INSERT%<your table>%'
This will find the usage only if INSERT and your table are on the same line.
However if the command is built more dynamically then you will not find it that simply.
You can use user_source or user_dependencies table as below.
Using table user_source
select * from user_source
where upper(text) like '%<YOUR TABLE NAME in UPPER CASE>%'
You can select from user_source , all_source , dba_source depending on user you have logged in and permission that user have.
Using table user_dependencies
SELECT NAME FROM user_dependencies WHERE referenced_name = '<YOUR TABLE NAME in UPPER CASE>'
UNION
SELECT referenced_name FROM user_dependencies WHERE name = '<YOUR TABLE NAME in UPPER CASE>'
You can select from user_dependencies , all_dependencies , dba_dependencies depending on user you have logged in and permission that user have.
I have created a VIEW by joining some number of tables. I used a SP to call that VIEW and in the SP I'm filtering the data set of the view using an ID. Now I need to pass this ID to VIEW and do the filtering inside the VIEW itself. What is the way of passing this ID as a parameter to view in Oracle 10g?
Current View
CREATE OR REPLACE FORCE VIEW "MY_VIEW"
//SELECT statements goes here
FROM MY_TABLE_1, MY_TABLE_2
//TABLE JOINS
where
//FILTERS
Current Stored Procedure
CREATE OR REPLACE PROCEDURE MY_SP
(
REQUESTACCOUNTID IN NUMBER
, p_cursor out SYS_REFCURSOR
) AS
internal_flag NUMBER;
BEGIN
open p_cursor for
SELECT //SELECT THE COLUMNS
from MY_VIEW my
WHERE my.account_id = REQUESTACCOUNTID;
END MY_SP;
What I need to do is, parse the parameter REQUESTACCOUNTID to the view while selecting
this is sorted out using a package variable. More explanation can be found using this URL
I need to be able to reconstruct a table column by using the column data in DBA_TAB_COLUMNS, and so to develop this I need to understand what each column refers to. I'm looking to understand what DATA_TYPE_MOD is -- the documentation (http://docs.oracle.com/cd/B19306_01/server.102/b14237/statviews_2094.htm#I1020277) says it is a data type modifier, but I can't seem to find any columns with this field populated or any way to populate this field with a dummy column. Anyone familiar with this field?
Data_type_mod column of the [all][dba][user]_tab_columns data dictionary view gets populated when a column of a table is declared as a reference to an object type using REF datatype(contains object identifier(OID) of an object it points to).
create type obj as object(
item number
) ;
create table tb_1(
col ref obj
)
select t.table_name
, t.column_name
, t.data_type_mod
from user_tab_columns t
where t.table_name = 'TB_1'
Result:
table_name column_name data_type_mod
-----------------------------------------
TB_1 COL REF
Oracle has a PL/SQL package that can be used to generate the DDL for creating a table. You would probably be better off using this.
See GET_DDL on http://docs.oracle.com/cd/B19306_01/appdev.102/b14258/d_metada.htm#i1019414

How to get Oracle create table statement in SQL*Plus
i have a existing table called property i alter a column called overbook_percent (i change a number 2 to 3) but i want to do a source search to make sure that there is not a variable declaration that sets this to just 2 digits. how would i go about this?not sure you called this a source search.
how can i see where this table column is use?
i tried this but get no output
select text
from dba_source
where upper(text) like 'OVERBOOK_MAX'
;
I'm working on toad for oracle
may be you are looking for this:-
select owner, table_name from all_tab_columns where column_name = 'OVERBOOK_MAX';
This will search all tables with a column name OVERBOOK_MAX
For checking in stored procedures you may try this:-
SELECT DISTINCT type, name
FROM dba_source
WHERE owner = 'OWNER'
AND UPPER(text) LIKE '%OVERBOOK_MAX%';
EDIT
to search a string try this:-
SELECT owner, name, type, line, text
FROM dba_source
WHERE instr(UPPER(text), UPPER(:search_string)) > 0;
