Is it possible to search every field of every table for a particular value in Oracle?
There are hundreds of tables with thousands of rows in some tables so I know th
Here is another modified version that will compare a lower substring match. This works in Oracle 11g.
DECLARE
match_count INTEGER;
-- Type the owner of the tables you are looking at
v_owner VARCHAR2(255) :='OWNER_NAME';
-- Type the data type you are look at (in CAPITAL)
-- VARCHAR2, NUMBER, etc.
v_data_type VARCHAR2(255) :='VARCHAR2';
-- Type the string you are looking at
v_search_string VARCHAR2(4000) :='%lower-search-sub-string%';
BEGIN
FOR t IN (SELECT table_name, column_name FROM all_tab_cols where owner=v_owner and data_type = v_data_type) LOOP
EXECUTE IMMEDIATE
'SELECT COUNT(*) FROM '||t.table_name||' WHERE lower('||t.column_name||') like :1'
INTO match_count
USING v_search_string;
IF match_count > 0 THEN
dbms_output.put_line( t.table_name ||' '||t.column_name||' '||match_count );
END IF;
END LOOP;
END;

Yes you can and your DBA will hate you and will find you to nail your shoes to the floor because that will cause lots of I/O and bring the database performance really down as the cache purges.
select column_name from all_tab_columns c, user_all_tables u where c.table_name = u.table_name;
for a start.
I would start with the running queries, using the v$session
and the v$sqlarea
. This changes based on oracle version. This will narrow down the space and not hit everything.
I don't of a simple solution on the SQL promprt. Howeve there are quite a few tools like toad and PL/SQL Developer that have a GUI where a user can input the string to be searched and it will return the table/procedure/object where this is found.
SELECT * from all_objects WHERE object_name like '%your_string%';
