Good day,
In DBeaver db manager we are able to transfer data directly from query to a table created by us. We right click>execute>export to a table.
Can anyone help me to do the same in oracle developer environment.
Here I have created a table in the same connection,and want to store query results into table.
Thank you
Right click on your table.
Choose Table - Copy.
Give it a name, and check 'Include Data'
You can see the code we're about to run by clicking on the SQL panel.
declare
l_sql varchar2(32767);
c_tab_comment varchar2(32767);
procedure run(p_sql varchar2) as
begin
execute immediate p_sql;
end;
begin
run('create table "HR".BEERS_COPY as select * from "HR"."BEERS" where '||11||' = 11');
begin
select comments into c_tab_comment from sys.all_TAB_comments where owner = 'HR' and table_name = 'BEERS' and comments is not null;
run('comment on table HR.BEERS_COPY is '||''''||REPLACE(c_tab_comment, q'[']', q'['']')||'''');
for tc in (select column_name from sys.all_tab_cols where owner = 'HR' and table_name = 'BEERS')
loop
for c in (select comments from sys.all_col_comments where owner = 'HR' and table_name = 'BEERS' and column_name=tc.column_name)
loop
run ('comment on column HR.BEERS_COPY.'||tc.column_name||' is '||''''||REPLACE(c.comments, q'[']', q'['']')||'''');
end loop;
end loop;
EXCEPTION
WHEN OTHERS THEN NULL;
end;
end;
So basically a CTAS + we grab the comments for you.

I am new to Oracle database, got a task to write several selects, but I do not get somethow principle, how it works (or better to say does not work). Could you please help me to find a mistake and probably you have a link to some info or converter that helps such writings.
v_sql := 'SELECT ''DROP TABLE ''||object_name||'' as
select *
FROM all_objects
WHERE object_name LIKE '''%''|| v_date ||''%'''
and object_type = ''TABLE''
and owner =''||v_owner||''';
Are you trying to generate DROP statements for a specific user? Start with the below anonymous block and add to it.
--Generate DROP statements for all tables for a user.
declare
v_owner varchar2(128) := user;
begin
for objects in
(
select distinct 'DROP TABLE "'||owner||'"."'||object_name||'"' v_sql
from all_objects
where object_type = 'TABLE'
and owner = v_owner
order by v_sql
) loop
dbms_output.put_line(objects.v_sql);
end loop;
end;

I have a 9 digit number, say "234234234", is there a way to find or check its appearance in my database, like in which particular schema or procedure does it fall? and list out all the tables and columns which has that value in pl/sql developer
This query only searches in stored objects that user is allowed to access (procedure, function, package, ...). You could refer to this
Not sure if there is one way to search for that value in all database table.
SELECT *
FROM all_source
WHERE text LIKE '%234234234%';
--AND owner = 'SCHEMA_NAME';
The below block identifies the given string's presence across all the tables in your DB.
declare
num_rows number;
sql_text varchar2(250);
sql_info varchar2(100);
begin
dbms_output.enable(1000000);
for x in (select table_name, column_name from dba_tab_columns
where data_type in ('VARCHAR','VARCHAR2','CHAR')
and owner <> 'SYSTEM')
loop
sql_text:='select count(*) into :num_rows from SYSTEM.'||x.table_name||' where '||x.column_name||' like ''%234234234%''';
-- dbms_output.put_line (sql_text);
execute immediate sql_text into num_rows;
if num_rows>0
then
sql_info:='Table: '||x.table_name||' contains the string';
dbms_output.put_line (sql_info);
end if;
end loop;
end;

I have a table with a column containing SQL query (select statements only) in BLOB format.
I'm trying to figure out a way to analyse the SQL queries, and check which tables each SQL queries will be accessing.
Anyone done anything similar?
My thought right now is to create a PLSQL loop that:
Converts the BLOB to text to get the SQL query
Execute an explain plan for the query
Look at the result of the explain plan, and get all the lines with TABLE ACCESS
Edit: I'm on Oracle Database 11g Release 11.2.0.4.0 - 64bit if that helps, and have read-only access to the database, so I'll need to create a solution that's not intrusive to the DB.
This could be another simpler method.
Create dynamic views for those SQLs in the BLOB field.
EXECUTE IMMEDIATE 'CREATE OR REPLACE VIEW YOUR_VIEW_NAME AS '||
utl_raw.cast_to_varchar2(dbms_lob.substr(blob_field));
Query user_dependencies to get the referenced table names.
SELECT referenced_name AS table_name
FROM user_dependencies
WHERE type = 'VIEW'
AND NAME = 'YOUR_VIEW_NAME'
AND referenced_type = 'TABLE';
So, here is how I have done it:
DECLARE
b BLOB;
c CLOB;
n NUMBER;
BEGIN
-- << loop_through_table >>
FOR o IN (SELECT TRIM(LABEL) lbl, REQUEST req FROM REQUEST_TABLE) LOOP
b := o.req;
IF ((b is null) OR (LENGTH(b)=0)) THEN
DBMS_OUTPUT.PUT_LINE(o.lbl || ' : No query found');
CONTINUE;
END IF;
-- Convert the BLOB to text to get the SQL query
DBMS_LOB.CREATETEMPORARY(c,TRUE);
n:=1;
-- << loop_through_blob >>
WHILE (n+32767<=LENGTH(b)) LOOP
DBMS_LOB.WRITEAPPEND(c,32767,UTL_RAW.CAST_TO_VARCHAR2(DBMS_LOB.SUBSTR(b,32767,n)));
n:=n+32767;
END LOOP;
DBMS_LOB.WRITEAPPEND(c,length(b)-n+1,UTL_RAW.CAST_TO_VARCHAR2(DBMS_LOB.SUBSTR(b,length(b)-n+1,n)));
-- Execute explain plan
execute immediate 'EXPLAIN PLAN SET STATEMENT_ID=''temp1'' FOR ' || c;
-- Look at the result of the explain plan, and get all the lines of OBJECT_TYPE='TABLE'
-- << loop_through_plan >>
FOR p IN ( SELECT OBJECT_NAME FROM PLAN_TABLE WHERE STATEMENT_ID='temp1' AND OBJECT_TYPE='TABLE') LOOP
DBMS_OUTPUT.PUT_LINE(o.lbl || ', ' || p.OBJECT_NAME);
END LOOP;
execute immediate 'DELETE FROM PLAN_TABLE WHERE STATEMENT_ID=''temp1'' ';
END LOOP;
DBMS_OUTPUT.PUT_LINE('-- Completed --');
END;
I have a table that contains a list of table names.
I would like to search each of these tables one by one to see if they contain a particular element (the primary key, specified at the start of the script).
I would like to return a list of all of the tables that this element is present in (ideally distinct).
I'm fairly new to this PL/SQL "not just a query" stuff. so i apologise in advance for the attrocious attempt you are about to see, but hopefully it illustrates what i'm going for:
PROCEDURE CHECK_FOR_ELEMENTS
BEGIN
DECLARE
ELEMENT_KEY varchar(5):=X78ehryfk;
RNUM_MAX int :=167;
----create output table for script
create or replace table ALL_TABLES CONTAINING_&ELEMENT_KEY
(ELEMENT_KEY VARCHAR(255),
TABLE_NAME varchar(255))
/
commit;
---begin loop over rnum;
FOR rnum_counter in 1..&RNUM_MAX
LOOP
--define this statement as variable TABLE_NAME_VAR
select table_name from (select * from (select table_name, rownum as rnum
from all_tables
where owner = 'RMS'
and table_name like 'ABC%'
and table_name not like '%STG'
and table_name not like '%BKP'
and num_rows>0
order by num_rows desc)
where rnum = rnum_counter
)INTO TABLE_NAME_VAR
;
----run below to collect row, if it exists, from table being searched
SQL_STMT:='INSERT INTO ALL_TABLES CONTAINING_&ELEMENT_KEY
SELECT distinct key,'||TABLE_NAME_VAR||' as UMF from
'||TABLE_NAME_VAR||
' where key like 'ELEMENT_KEY-%'
execute immediate SQL_STMT;
commit;
---insert row into table created for output
END LOOP
---loop over all tables
END;
The main error message i get is that TABLE_NAME_VAR is not a valid table name within the dynamic SQL statement. I've googled a bit and i now understand you can't use variables to input table names in this way.
Any help is greatly appreciated!
Thankyou!
Here, I tried to clean it up for you. Let me know if you still get errors.
create or replace PROCEDURE CHECK_FOR_ELEMENTS is
ELEMENT_KEY varchar2(14):='X78ehryfk';
RNUM_MAX int :=167;
TABLE_NAME_VAR varchar2(30);
SQL_STMT varchar2(4000);
BEGIN
----create output table for script
begin
execute immediate 'drop table ALL_TABLES_WITH_' || element_key;
exception when others then null;
end;
execute immediate 'create table ALL_TABLES_WITH_' || element_key || '
(ELEMENT_KEY VARCHAR2(255), -- does this need to be 255 characters?
TABLE_NAME varchar2(30))';
--- implicit cursor loop
FOR rnum_row in (select table_name, rownum as rnum
from all_tables
where owner = 'RMS'
and table_name like 'ABC%'
and table_name not like '%STG'
and table_name not like '%BKP'
and num_rows>0
order by num_rows desc)
LOOP
if rnum_row.rnum > RNUM_MAX
then exit;
end if;
TABLE_NAME_VAR := rnum_row.table_name;
----run below to collect row, if it exists, from table being searched
SQL_STMT:='INSERT INTO ALL_TABLES_WITH_' || element_key || '
(ELEMENT_KEY, TABLE_NAME)
SELECT distinct key, :1 as UMF from
'||TABLE_NAME_VAR||
' where key like :2';
execute immediate SQL_STMT using TABLE_NAME_VAR, element_key || '-%';
---insert row into table created for output
END LOOP;
commit;
---loop over all tables
END CHECK_FOR_ELEMENTS;

I found many such questions but the answers where all using Stored Procedures.
I want an answer that uses purely a query in Oracle Sql Developer.
I have a value 'CORE_AO0001031_70_EMail_1' but not sure in which table. The number of tables and the data inside them are very huge.
Doesn't matter if the query is huge and will take time to execute. Is there any such query?
The reason for my asking a query is, I don't have privilege to create a Stored Procedure and I won't be given that privilege. Please help me with a query.
With an SQL you can't, as the queries are going to be dynamic. You have to execute a PL/SQL atleast.
Note: This is a Costly operation!
You can still attempt a full download of all you tables as spooling, and make PERL search into all files. In that case, you need a lot of disk space, but less harm(Just better than the Pl/SQL) to the database
