I have an SQL 2005 database and I know that in the database there is a table which has got some xml strings in it. How can I find this table(s)?
If the fields are actually of type XML, then this query will give you what you're looking for:
select * from information_schema.columns
where DATA_TYPE = 'XML'

Run this:
select 'select distinct ''' || a.name || '.' || b.name
|| ''' from ' || b.name
|| 'where ' || b.name || ' like ''%<%/>%'' union '
from systable a
join syscolumns b on (a.id = b.id)
join systypes c on (b.type = c.xtype)
where a.type ='U' and c.name = ('CHAR', 'CHARN', 'VARCHAR', 'VARCHARN');
The first result set will have one row per character column in the database:
select distinct 'table.column' from table where column like '%<%/>%' union
Take that resultset, snip off the last union, and run the resultset as a SQL statement. It'll bring back the table name and column name for any column that has one or more rows that look XML-ish.
Edit: this is from memory; the join to systypes and the type names may be wrong, so select from systypes and check.

I have this existing query
Select
mt.First_name,
mt.Last_name as OLD_Last_name,
ot.Last_name as New_Last_name,
ot.Date as Update_Date,
from maintable as mt
JOIN othertable as ot on mt.id=ot.id
I'd like to join a new column with the following output:
[mt.First_name] [ot.Last_name], nee [mt.Last_name] changed their name on [ot.Date].
I tried using a case statement but didn't get it right.
For closure, moving #Jnevill answer from comment to actual answer:
SELECT mt.First_name || ' ' || ot.Last_name || ', nee ' || mt.last_name || ' changed their name on ' || ot.Date AS yournewcolumn, mt.First_name
, mt.Last_name as OLD_Last_name
, ot.Last_name as New_Last_name
, ot.Date as Update_Date
from maintable as mt
JOIN othertable as ot on mt.id=ot.id
Apparently OP wanted to know how to concatenate strings, which is done with ||.
I am new to Oracle and hope someone here can help me with this.
I have a Select that returns the following without row aggregation:
current output
My problem here is that I can have multiple rows for certain IDs in the first column whereas I need just one row per ID, like this:
required output
Select Distinct is not an option in my case and Listag doesn't allow enough characters for the second column.
After some research I think Xmlagg is exactly what I need here but I cannot get this to work and always get an error here so I think I am writing it wrong.
Latest error:
ORA-00931: missing identifier
Can someone show me how to write this properly ?
My query (shortened):
ALTER SESSION ENABLE PARALLEL QUERY;
SELECT
a.Id
, RTRIM(XMLAGG(XMLELEMENT("Details",
(
b.title || ' -' || c.item || ' -' || b.quantity) ORDER BY b.title)
).EXTRACT('//text()'), ' --- ') AS Details
, TO_CHAR(c.total, 'FM9,990.00') AS Sum
FROM
table1 d
/* joins */
WHERE
/* ... */
GROUP BY
a.Id
, b.title
, c.item
, b.quantity
ORDER BY
a.Id
Many thanks in advance.

Just a few things need to be moved here and there.
SELECT a.Id ,
RTRIM(XMLAGG(XMLELEMENT("Details", b.title
|| ' -'
|| c.item
|| ' -'
|| b.quantity ,' --- ' ).EXTRACT('//text()')
ORDER BY b.title),
' --- ')
AS
Details , TO_CHAR(c.total, 'FM9,990.00')
AS
SUM FROM table1 d
/* joins */
WHERE
* ... */
GROUP BY
a.Id
, b.title
, c.item
, b.quantity
ORDER BY
a.Id
I have the start of a query below which gives me dependencies of a particular table:
SELECT DISTINCT OBJECT_NAME(object_id) AS referencing_object_name
FROM sys.sql_dependencies
WHERE referenced_major_id = OBJECT_ID('TABLE_NAME_HERE')
But is there a way to alter this to show:
1) The above with a column with tablename being populated
2) The above relating to ALL tables within a set database (not just a single table as the original query shows)
3) All results on a single row
Final output looking like image below:

EDIT:
I seem to be very close with this, but last column is duplicating a single result
SELECT DISTINCT b.name, a.referenced_major_id, b.object_id,
substring((
SELECT ' || ' +OBJECT_NAME(a.object_id)
FROM sys.sql_dependencies a JOIN sys.tables b ON a.referenced_major_id = b.object_id
For XML PATH ('')
), 2, 1000) AS [TextLine]
FROM sys.sql_dependencies a JOIN sys.tables b ON a.referenced_major_id = b.object_id
ORDER BY b.name ASC
Sorry if this is a duplicate. I have searched but only find aliasing fields and tables.
I have a query:
SELECT *
FROM MyTable1 ca LEFT OUTER JOIN MyTable2 dcn ON dcn.dstrct_code = ca.dstrct_code
LEFT OUTER JOIN MyTable2 cdn ON cdn.dstrct_code = ca.cost_dstrct_cde
LEFT OUTER JOIN MyTable3 bb ON bb.supplier_code = ca.supplier_code
WHERE ca.dstrct_code = '0001'
AND ca.req_232_type = 'P'
AND ca.requisition_no = '264982 000'
AND ca.alloc_count = '01'
ORDER BY ca.alloc_count ASC
Please dont shoot me down for using * im not done with the query yet. If I execute this query I get a row of data however the tables I am selecting from all have a good number of fields and many are simularly named. So my question is... Is there anyway to select * from and append the table name to the field name so it is more obvious which field belongs to which table?
I don't think there's a way to do that directly but you can do this instead. Run a query like this:
SELECT
(case t.name when 'MyTable1' then 'ca' when 'MyTable2' then 'dcn' when 'MyTable3' then 'cdn' when 'MyTable4' then 'bb' end)
+ '.' + c.name
+ ' AS "' + t.name + '.' + c.name + '",'
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE t.name in ('MyTable1', 'MyTable2', 'MyTable3', 'MyTable4')
ORDER BY t.name
Run it, preferably with results to Text (Ctrl+T), and use the results instead of the * in your original query. You have to manually remove the comma from the last line.
If you like the approach, you could streamline the process with some dynamic SQL.
We have a large Oracle database with many tables. Is there a way I can query or search to find if there are any tables with certain column names?
IE show me all tables that have the columns: id, fname, lname, address
Detail I forgot to add: I need to be able to search through different schemas. The one I must use to connect doesn't own the tables I need to search through.
To find all tables with a particular column:
select owner, table_name from all_tab_columns where column_name = 'ID';
To find tables that have any or all of the 4 columns:
select owner, table_name, column_name
from all_tab_columns
where column_name in ('ID', 'FNAME', 'LNAME', 'ADDRESS');
To find tables that have all 4 columns (with none missing):
select owner, table_name
from all_tab_columns
where column_name in ('ID', 'FNAME', 'LNAME', 'ADDRESS')
group by owner, table_name
having count(*) = 4;
TO search a column name use the below query if you know the column name accurately:
select owner,table_name from all_tab_columns where upper(column_name) =upper('keyword');
TO search a column name if you dont know the accurate column use below:
select owner,table_name from all_tab_columns where upper(column_name) like upper('%keyword%');
The data you want is in the "cols" meta-data table:
SELECT * FROM COLS WHERE COLUMN_NAME = 'id'
This one will give you a list of tables that have all of the columns you want:
select distinct
C1.TABLE_NAME
from
cols c1
inner join
cols c2
on C1.TABLE_NAME = C2.TABLE_NAME
inner join
cols c3
on C2.TABLE_NAME = C3.TABLE_NAME
inner join
cols c4
on C3.TABLE_NAME = C4.TABLE_NAME
inner join
tab t
on T.TNAME = C1.TABLE_NAME
where T.TABTYPE = 'TABLE' --could be 'VIEW' if you wanted
and upper(C1.COLUMN_NAME) like upper('%id%')
and upper(C2.COLUMN_NAME) like upper('%fname%')
and upper(C3.COLUMN_NAME) like upper('%lname%')
and upper(C4.COLUMN_NAME) like upper('%address%')
To do this in a different schema, just specify the schema in front of the table, as in
SELECT * FROM SCHEMA1.COLS WHERE COLUMN_NAME LIKE '%ID%';
If you want to combine the searches of many schemas into one output result, then you could do this:
SELECT DISTINCT
'SCHEMA1' AS SCHEMA_NAME
,TABLE_NAME
FROM SCHEMA1.COLS
WHERE COLUMN_NAME LIKE '%ID%'
UNION
SELECT DISTINCT
'SCHEMA2' AS SCHEMA_NAME
,TABLE_NAME
FROM SCHEMA2.COLS
WHERE COLUMN_NAME LIKE '%ID%'
Here is one that we have saved off to findcol.sql so we can run it easily from within SQLPlus
set verify off
clear break
accept colnam prompt 'Enter Column Name (or part of): '
set wrap off
select distinct table_name,
column_name,
data_type || ' (' ||
decode(data_type,'LONG',null,'LONG RAW',null,
'BLOB',null,'CLOB',null,'NUMBER',
decode(data_precision,null,to_char(data_length),
data_precision||','||data_scale
), data_length
) || ')' data_type
from all_tab_columns
where column_name like ('%' || upper('&colnam') || '%');
set verify on
