Interrogate the columns of all tables

Hello
I called A, B, C... upto z. of these 26 paintings of paintings, 15 tables have the column common name "AAA". Now, I want to find the names of the tables in which there is a column name "AAA". for example, if this column name 'AAA' is present in the tables B, F, G,... Y(15 tables). The query should display all the table names. Here, in this example we donot know what table is the name of the column "AAA". We find the tables where is the name of the column "AAA"?

Thanks in advance...

Let me know if you have any confusion with my question.

Hello

What exactly do you do?

If you want to display the tables containing these columns, you can query the view data dictionary USER_TAB_COLS (or ALL_TAB_COLS, or, if you have privileges, DBA_TAB_COLS).

For example:

SELECT table_name, column_name

Of user_tab_cols

WHERE nom_de_colonne IN ('DNAME', 'FNAME', 'FIRST_NAME', 'LAST_NAME', 'LNAME') - or else

ORDER BY table_name, column_name

If you are running this as a different user than the ADMIN you will also need to add the schema name.
```
EXECUTE IMMEDIATE 'SELECT COUNT(*) FROM ' ||t1.owner||'.'||t1.table_name|| ' WHERE ' ||t1.column_name || ' = :1' INTO cnt USING v_data;
```
The error could be any strange names of tables or columns. For example, if they contain spaces in the name.
If you have names, then all identifieres must be placed in "."

+ untested example +.

I added a new column with an alias "get data". This new column will display "NO" is the entire column is zero and 'YES' if there is even a value not null in the column. But caution is that statistics table must be updated to get the correct results.

Your idea is good, you missed only to use the correct table name:

SELECT DBMS_METADATA.get_ddl ('TABLE', table_name)
FROM user_tables;

How to hide the column in a table in the adf.

I created the table of the ADF and surround it in the collection of panels, the data in the table from the bean to support variable. Depending on the State, there are a few columns that must hide with the user. I used visible = "false", where the false value will come from backing bean. However the user to the table always have the ability to display the column. Is there any one to hide the column with the user at all times. Fixing the code example:
< af:column sortable = "false" headerText = "column1" id = "c13" visible = "false" >
"" < af:outputText value = "{row.columns1} ' id ="ot13"/ >
< / af:column >

Can be parallelized Alter the dimensions of the column to change tables
Hi all

Can be parallelized Alter tables to the dimensions of the column to change.

I was able to set the explain plan of parallelized command CREATE INDEX and CREATE TABLE STATEMENTS and view the plan of the explain command.
But when I try to apply the market in PARALLEL for an ALTER TABLE to change column size, explain the plan is a failure.

Ex:
EXPLAIN THE PLAN TO ALTER / * + PARALLEL (10) * / EMP_BLKP_1 TABLE MODIFY ENAME VARCHAR2 (40);
ORA-00900: invalid SQL statement

But when I run the alter even outside the plan to explain that it works very well. But I don't know if parallelism is applied for that change the order.

Receive your answer.

Thank you

InStr/substr logic to update the column in a table db 9i / 10g / 11g
Hi all

I have a table Test_table with email_address column.
Please update the table and remove
[email protected] and
[email protected]
email_address column.

Current values of the Email_address column

[email protected], ken. [email protected], [email protected], [email protected]
2.Ken. [email protected], [email protected], [email protected]; [email protected]
3 ken. [email protected], [email protected], [email protected], [email protected]

The new value must be
1 ken. [email protected], [email protected]
Ken 2. [email protected], [email protected], [email protected]
3 ken. [email protected], [email protected]

If email_address to remove is the first email address in the column
Then, remove the first comma too, otherwise delete the comma above and email address.

I created a C1 cursor, but I know is not the logic to use to get the new value
Any help will be greately appreciated.

Declare
Cursor c1 is select rowid, email_address
From Test_table
Where (at the top (email_address) like ('% [email protected]%'))
GOLD (superior (email_address) like '% [email protected]%');
V_new_email varchar2 (200);
BEGIN
FOR rec IN C1 LOOP
-do not know how to handle V_new_email to be able to update the table with the current values.
V_new_email: = - some function instr/substr here

Update Test_table
Define email_address = V_new_email
Where rowid = rec.rowid;

END OF LOOP
END;

Thank you
