You can use the ALL_OBJECT view for including only Tables as follows:
SELECT
ATT.OWNER,
ATT.TABLE_NAME,
ATT.COLUMN_NAME
FROM
ALL_TAB_COLUMNS ATT JOIN ALL_OBJECTS AO
ON ATT.TABLE_NAME = AO.OBJECT_NAME AND ATT.OWNER = AO.OWNER
WHERE
DATA_TYPE IN (
'VARCHAR2',
'VARCHAR',
'NCHAR',
'NVARCHAR2'
)
AND AO.OBJECT_TYPE = 'TABLE'
You could join your query on all_objects and check that the object type is a table:
SELECT owner,
table_name,
column_name
FROM all_tab_columns atc
JOIN all_object ao ON atc.table_name = ao.object_name AND
atc.owner = ao.owner
WHERE data_type IN ('VARCHAR2', 'VARCHAR', 'NCHAR', 'NVARCHAR2') AND
object_type = 'TABLE'

I'm running the below which once executed, an error is reported telling me that EST_ONE_ROW_MB is an invalid identifier.
I've been advised I perhaps need to get the dynamic SQL part running as a stand alone query to begin with as an initial troubleshooting exercise but I'm a bit stumped in terms of how to write a sub-query here that will produce the desired output and eliminate the error.

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 this could take a very long time to query. But the only thing I know is that a value for the field I would like to query against is 1/22/2008P09RR8.
<
I've tried using this statement below to find an appropriate column based on what I think it should be named but it returned no results.
SELECT * from dba_objects
WHERE object_name like '%DTN%'
There is absolutely no documentation on this database and I have no idea where this field is being pulled from.
Any thoughts?
Quote:
I've tried using this statement below

SELECT * from dba_objects WHERE
object_name like '%DTN%'
A column isn't an object. If you mean that you expect the column name to be like '%DTN%', the query you want is:
SELECT owner, table_name, column_name FROM all_tab_columns WHERE column_name LIKE '%DTN%';
But if the 'DTN' string is just a guess on your part, that probably won't help.
By the way, how certain are you that '1/22/2008P09RR8' is a value selected directly from a single column? If you don't know at all where it is coming from, it could be a concatenation of several columns, or the result of some function, or a value sitting in a nested table object. So you might be on a wild goose chase trying to check every column for that value. Can you not start with whatever client application is displaying this value and try to figure out what query it is using to obtain it?
Anyway, diciu's answer gives one method of generating SQL queries to check every column of every table for the value. You can also do similar stuff entirely in one SQL session using a PL/SQL block and dynamic SQL. Here's some hastily-written code for that:
SET SERVEROUTPUT ON SIZE 100000
DECLARE
match_count INTEGER;
BEGIN
FOR t IN (SELECT owner, table_name, column_name
FROM all_tab_columns
WHERE owner <> 'SYS' and data_type LIKE '%CHAR%') LOOP
EXECUTE IMMEDIATE
'SELECT COUNT(*) FROM ' || t.owner || '.' || t.table_name ||
' WHERE '||t.column_name||' = :1'
INTO match_count
USING '1/22/2008P09RR8';
IF match_count > 0 THEN
dbms_output.put_line( t.table_name ||' '||t.column_name||' '||match_count );
END IF;
END LOOP;
END;
/
There are some ways you could make it more efficient too.
In this case, given the value you are looking for, you can clearly eliminate any column that is of NUMBER or DATE type, which would reduce the number of queries. Maybe even restrict it to columns where type is like '%CHAR%'.
Instead of one query per column, you could build one query per table like this:
SELECT * FROM table1
WHERE column1 = 'value'
OR column2 = 'value'
OR column3 = 'value'
...
;
I did some modification to the above code to make it work faster if you are searching in only one owner.
You just have to change the 3 variables v_owner, v_data_type and v_search_string to fit what you are searching for.
SET SERVEROUTPUT ON SIZE 100000
DECLARE
match_count INTEGER;
-- Type the owner of the tables you are looking at
v_owner VARCHAR2(255) :='ENTER_USERNAME_HERE';
-- 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) :='string to search here...';
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 '||t.column_name||' = :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;

I know this is an old topic. But I see a comment to the question asking if it could be done in SQL rather than using PL/SQL. So thought to post a solution.
The below demonstration is to Search for a VALUE in all COLUMNS of all TABLES in an entire SCHEMA:
Search a CHARACTER type
Let's look for the value KING in SCOTT schema.
SQL> variable val varchar2(10)
SQL> exec :val := 'KING'
PL/SQL procedure successfully completed.
SQL> SELECT DISTINCT SUBSTR (:val, 1, 11) "Searchword",
2 SUBSTR (table_name, 1, 14) "Table",
3 SUBSTR (column_name, 1, 14) "Column"
4 FROM cols,
5 TABLE (xmlsequence (dbms_xmlgen.getxmltype ('select '
6 || column_name
7 || ' from '
8 || table_name
9 || ' where upper('
10 || column_name
11 || ') like upper(''%'
12 || :val
13 || '%'')' ).extract ('ROWSET/ROW/*') ) ) t
14 ORDER BY "Table"
15 /
Searchword Table Column
----------- -------------- --------------
KING EMP ENAME
SQL>
Search a NUMERIC type
Let's look for the value 20 in SCOTT schema.
SQL> variable val NUMBER
SQL> exec :val := 20
PL/SQL procedure successfully completed.
SQL> SELECT DISTINCT SUBSTR (:val, 1, 11) "Searchword",
2 SUBSTR (table_name, 1, 14) "Table",
3 SUBSTR (column_name, 1, 14) "Column"
4 FROM cols,
5 TABLE (xmlsequence (dbms_xmlgen.getxmltype ('select '
6 || column_name
7 || ' from '
8 || table_name
9 || ' where upper('
10 || column_name
11 || ') like upper(''%'
12 || :val
13 || '%'')' ).extract ('ROWSET/ROW/*') ) ) t
14 ORDER BY "Table"
15 /
Searchword Table Column
----------- -------------- --------------

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.
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;

I modified Flood's script to execute once for each table rather than for every column of each table for faster execution. It requires Oracle 11g or greater.

-- The string to be searched for (case-insensitive)
v_search_string varchar2(4000) := 'FIND_ME';
-- Store the SQL to execute for each table in a CLOB to get around the 32767 byte max size for a VARCHAR2 in PL/SQL
v_sql clob := '';

(select table_name from all_tab_columns where owner = all_tables.owner and data_type like '%' || upper(v_data_type) || '%')
order by table_name) loop
v_counter := 0;
v_sql := '';
for cur_columns in (select column_name from all_tab_columns where
owner = v_owner and table_name = cur_tables.table_name and data_type like '%' || upper(v_data_type) || '%') loop

v_sql := v_sql || ' or ';

I was having following issues for #Lalit Kumars answer,
ORA-19202: Error occurred in XML processing
ORA-00904: "SUCCESS": invalid identifier
ORA-06512: at "SYS.DBMS_XMLGEN", line 288
ORA-06512: at line 1
19202. 00000 - "Error occurred in XML processing%s"
*Cause: An error occurred when processing the XML function
*Action: Check the given error message and fix the appropriate problem
Solution is:
WITH char_cols AS
(SELECT /*+materialize */ table_name, column_name
FROM cols
WHERE data_type IN ('CHAR', 'VARCHAR2'))
SELECT DISTINCT SUBSTR (:val, 1, 11) "Searchword",
SUBSTR (table_name, 1, 14) "Table",
SUBSTR (column_name, 1, 14) "Column"
FROM char_cols,
TABLE (xmlsequence (dbms_xmlgen.getxmltype ('select "'
|| column_name
|| '" from "'
|| table_name
|| '" where upper("'
|| column_name
|| '") like upper(''%'
|| :val
|| '%'')' ).extract ('ROWSET/ROW/*') ) ) t
ORDER BY "Table"
/
I would do something like this (generates all the selects you need).
You can later on feed them to sqlplus:
echo "select table_name from user_tables;" | sqlplus -S user/pwd | grep -v "^--" | grep -v "TABLE_NAME" | grep "^[A-Z]" | while read sw;
do echo "desc $sw" | sqlplus -S user/pwd | grep -v "\-\-\-\-\-\-" | awk -F' ' '{print $1}' | while read nw;
do echo "select * from $sw where $nw='val'";
done;
done;
It yields:
select * from TBL1 where DESCRIPTION='val'
select * from TBL1 where ='val'
select * from TBL2 where Name='val'
select * from TBL2 where LNG_ID='val'
And what it does is - for each table_name from user_tables get each field (from desc) and create a select * from table where field equals 'val'.
if we know the table and colum names but want to find out the number of times string is appearing for each schema:
Declare
owner VARCHAR2(1000);
tbl VARCHAR2(1000);
cnt number;
ct number;
str_sql varchar2(1000);
reason varchar2(1000);
x varchar2(1000):='%string_to_be_searched%';

if rec3.ct <> 0 then

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.
There are some free tools that make these kind of search, for example, this one works fine and source code is available:
https://sites.google.com/site/freejansoft/dbsearch
You'll need the Oracle ODBC driver and a DSN to use this tool.
Modifying the code to search case-insensitively using a LIKE query instead of finding exact matches...
DECLARE
match_count INTEGER;
-- Type the owner of the tables you want to search.
v_owner VARCHAR2(255) :='USER';
-- Type the data type you're looking for (in CAPS). Examples include: VARCHAR2, NUMBER, etc.
v_data_type VARCHAR2(255) :='VARCHAR2';
-- Type the string you are looking for.
v_search_string VARCHAR2(4000) :='Test';
BEGIN
dbms_output.put_line( 'Starting the search...' );

IF match_count > 0 THEN
dbms_output.put_line( t.table_name ||' '||t.column_name||' '||match_count );

|| COLUMN_NAME || '") LIKE UPPER(''%' || :val || '%'')' ).EXTRACT ('ROWSET/ROW/*')))
ORDER BY "Table";
The Oracle LIKE condition allows wildcards to be used in the WHERE clause of a SELECT, INSERT, UPDATE, or DELETE statement.
%: to match any string of any length
Eg-
SELECT last_name
FROM customer_tab
WHERE last_name LIKE '%A%';
-: to match on a single character
Eg-
SELECT last_name
FROM customer_tab
WHERE last_name LIKE 'A_t';
I have a oracle script to convert table structure from Oracle to Redshift kind of below,
WITH TABLE_SCRIPT AS (
SELECT
TABLE_NAME,
COLUMN_NAME,
CASE
WHEN DATA_TYPE= 'DATE' THEN 'DATE'
WHEN DATA_TYPE= 'DATETIME' THEN 'TIMESTAMP'
WHEN DATA_TYPE LIKE 'TIMESTAMP%' THEN 'TIMESTAMP'
WHEN DATA_TYPE= 'LONG' THEN 'TEXT'
WHEN DATA_TYPE= 'NCHAR' THEN 'NCHAR(' || DATA_LENGTH || ')'
WHEN DATA_TYPE= 'NVARCHAR' THEN 'NVARCHAR(' || DATA_LENGTH || ')'
FROM ALL_TAB_COLUMNS
WHERE
OWNER= 'SMART_DS'
AND TABLE_NAME = 'BATCH'
ORDER BY DATA_TYPE,COLUMN_ID
)
SELECT 'CREATE TABLE '||MAX(TABLE_NAME) ||' (' as text FROM TABLE_SCRIPT
UNION ALL
SELECT ' '||COLUMN_NAME||' '||REDSHIFT_COLUMN_DEFINITION || ', ' AS TEXT FROM TABLE_SCRIPT
UNION ALL
SELECT ' );' AS TEXT FROM dual
When I run this script it has to run perfectly. My problem is ' , ' should not come at the end of second row, how to change that?
CREATE TABLE VERSION
(
RELEASE_ID DOUBLE PRECISION NOT NULL ,
VERSION_ID DOUBLE PRECISION NOT NULL ,
)
N.B. you missed out the end of your case statement in your table_script subquery, so I had to guess what it should be.
You can do this by using listagg, which removes the need to have separate union all'd select statements:
WITH table_script AS
(SELECT owner,
table_name,
column_name,
data_type,
CASE
WHEN data_type = 'DATE' THEN 'DATE'
WHEN data_type = 'DATETIME' THEN 'TIMESTAMP'
WHEN data_type LIKE 'TIMESTAMP%' THEN 'TIMESTAMP'
WHEN data_type = 'LONG' THEN 'TEXT'
WHEN data_type = 'NCHAR' THEN 'NCHAR(' || data_length || ')'
WHEN data_type = 'NVARCHAR' THEN 'NVARCHAR(' || data_length || ')'
ELSE
data_type
END redshift_column_definition,
column_id
FROM all_tab_columns
WHERE owner = 'SMART_DS'
AND table_name = 'BATCH')
SELECT 'create table ' || owner || '.' || table_name || ' (' || chr(10) || listagg(column_name || ' ' || redshift_column_definition, ',' || chr(10)) within GROUP(ORDER BY column_id) || chr(10) || ' );' AS text
FROM table_script
GROUP BY owner,
table_name
ORDER BY owner,
table_name;
Example output:
create table SYS.ALL_IDENTIFIERS (
OWNER VARCHAR2,
NAME VARCHAR2,
SIGNATURE VARCHAR2,
TYPE VARCHAR2,
OBJECT_NAME VARCHAR2,
OBJECT_TYPE VARCHAR2,
USAGE VARCHAR2,
USAGE_ID NUMBER,
LINE NUMBER,
COL NUMBER,
USAGE_CONTEXT_ID NUMBER
);
You'll note that I have added owner into the mix; this means you can create all the create table scripts in one go.
If you won't to use ListAgg. I Can suggest you to this query below, I tried it and it worked fine:
WITH
TABLE_SCRIPT
AS
( SELECT TABLE_NAME,
COLUMN_NAME,
(CASE
WHEN DATA_TYPE = 'DATE'
THEN
'DATE'
WHEN DATA_TYPE = 'DATETIME'
THEN
'TIMESTAMP'
WHEN DATA_TYPE LIKE 'TIMESTAMP%'
THEN
'TIMESTAMP'
WHEN DATA_TYPE = 'LONG'
THEN
'TEXT'
WHEN DATA_TYPE = 'NCHAR'
THEN
'NCHAR(' || DATA_LENGTH || ')'
WHEN DATA_TYPE = 'NVARCHAR'
THEN
'NVARCHAR(' || DATA_LENGTH || ')'
ELSE
DATA_TYPE
END) REDSHIFT_COLUMN_DEFINITION
,
ROWNUM
RankOfCol
FROM ALL_TAB_COLUMNS
WHERE OWNER = 'SMART_DS' AND TABLE_NAME = 'BATCH'
ORDER BY rankofcol, DATA_TYPE, COLUMN_ID)
(SELECT 'CREATE TABLE ' || MAX (TABLE_NAME) || ' (' AS TEXT
FROM TABLE_SCRIPT
UNION ALL
SELECT ' ' || COLUMN_NAME ||' '||REDSHIFT_COLUMN_DEFINITION || ' ' AS TEXT FROM TABLE_SCRIPT WHERE rankofcol = 1
UNION ALL
SELECT ', ' || COLUMN_NAME || ' '||REDSHIFT_COLUMN_DEFINITION ||' ' AS TEXT FROM TABLE_SCRIPT WHERE rankofcol > 1
UNION ALL
SELECT ' );' AS TEXT FROM DUAL);
Hope this can help you.
I have below Select query which will generate delete statements to delete all objects in schema.
select 'DROP '||OBJECT_TYPE||' '||OWNER||'.'||OBJECT_NAME
|| case when OBJECT_TYPE = 'TABLE'
then ' CASCADE CONSTRAINTS PURGE' else '' end
||';'
from all_objects
where OWNER = 'RATOR_MONITORING';
I want to create batch file and suppose that instead of generating delete statements separetly I can create may be cursor or something and save it in batch file and run the batch file to delete all contents in schema. How to do it?
You can find many script in the Internet. Neither of them work on 100%. There can we various gotchas. Like scheduler chains or materialized view groups.
This is the one I use (it is also inspired by one I found in the Internet)
set serveroutput on size unlimited
declare
v_ItemCount integer;
begin
SELECT count(*)
INTO v_ItemCount
FROM ALL_OBJECTS AO
WHERE AO.OWNER = '&USER'
AND AO.OBJECT_TYPE NOT IN ('INDEX', 'LOB')
AND AO.OBJECT_NAME NOT LIKE 'BIN$%';
while (v_ItemCount > 0) loop
for v_Cmd in (SELECT 'drop ' || AO.OBJECT_TYPE || ' ' || '"'||AO.OWNER||'"'|| '.' || '"'||AO.OBJECT_NAME||'"' ||
DECODE(AO.OBJECT_TYPE,
'TABLE',
' CASCADE CONSTRAINTS',
'') as DROPCMD,
AO.OWNER,
AO.OBJECT_TYPE,
AO.OBJECT_NAME
FROM ALL_OBJECTS AO
WHERE AO.OWNER = '&USER'
AND AO.OBJECT_TYPE NOT IN ('INDEX', 'LOB')
AND AO.OBJECT_NAME NOT LIKE 'BIN$%')
loop
begin
if v_Cmd.OBJECT_TYPE = 'SCHEDULE' then
DBMS_SCHEDULER.DROP_SCHEDULE(v_Cmd.OWNER||'.'||v_Cmd.OBJECT_NAME, true);
ELSIF v_Cmd.OBJECT_TYPE = 'JOB' then
DBMS_SCHEDULER.DROP_JOB(v_Cmd.OWNER||'.'||v_Cmd.OBJECT_NAME, true);
ELSIF v_Cmd.OBJECT_TYPE = 'PROGRAM' then
DBMS_SCHEDULER.DROP_PROGRAM(v_Cmd.OWNER||'.'||v_Cmd.OBJECT_NAME, true);
else
execute immediate v_Cmd.dropcmd;
end if;
dbms_output.put_line(v_Cmd.dropcmd);
exception
when others then
null; -- ignore errors
end;
end loop;
SELECT count(*)
INTO v_ItemCount
FROM ALL_OBJECTS AO
WHERE AO.OWNER = '&USER'
AND AO.OBJECT_TYPE NOT IN ('INDEX','LOB')
AND AO.OBJECT_NAME NOT LIKE 'BIN$%';
end loop;
execute immediate 'purge dba_recyclebin';
end;
Here is the script
begin
for i in (select * from dba_objects where owner = 'SO' and object_type <> 'TABLE')
loop
execute immediate 'drop ' || i.object_type || ' ' || i.object_name;
end loop;
for j in (select * from dba_objects where owner = 'SO' and object_type = 'TABLE')
loop
execute immediate 'drop ' || j.object_type || ' ' || j.object_name || ' cascade constraints';
end loop;
end;

Here we go i have compiled a shell to perform the Purge Schema. Let me know if this helps.

This is fu function:
create or replace
FUNCTION pk_max_value(t_name VARCHAR) RETURN NUMBER
is
rws number;
pk_column_name varchar(300);
sql_text VARCHAR(2048);
BEGIN
sql_text := 'SELECT cols.column_name ' ||
'FROM all_constraints cons, all_cons_columns cols ' ||
'WHERE cols.table_name = ' || t_name ||
' AND cons.constraint_type = ' || 'chr(39) P chr(39) ' ||
'AND cons.constraint_name = cols.constraint_name ' ||
'AND cons.owner = cols.owner ' ||
'ORDER BY cols.table_name, cols.position;';
execute immediate sql_text into pk_column_name;
sql_text := 'SELECT MAX(' || pk_column_name || ') FROM ' || t_name;
EXECUTE IMMEDIATE sql_text INTO rws;
RETURN rws;
END;
when I execute this, Oracle gives me an answer:
SQL command not properly ended.
Can somebody tell me, where is my fall?
First sql_text should not end with ;
And should be:
sql_text := 'SELECT cols.column_name
FROM all_constraints cons, all_cons_columns cols
WHERE cols.table_name = '''||t_name||'''
AND cons.constraint_type = ''P''
AND cons.constraint_name = cols.constraint_name
AND cons.owner = cols.owner
ORDER BY cols.table_name, cols.position';
Obs: this function will fail when PK type is not NUMBER.
Obs2: the t_name should come uppercase...
