I wanna comment all columns of all tables where the column have Foreing key with one especific table.
I know comment one by one, but they are many fields
SELECT
'COMMENT ON COLUMN ' as command1,
SYS.ALL_TAB_COLUMNS.OWNER,
'.' as command2,
SYS.ALL_TAB_COLUMNS.TABLE_NAME,
'.' as command3,
SYS.ALL_TAB_COLUMNS.COLUMN_NAME,
' is ''#Enumeration=boleano' as coment_to_add,
SYS.ALL_COL_COMMENTS.COMMENTS,
''';' as command5
FROM
SYS.ALL_TAB_COLUMNS
INNER JOIN SYS.ALL_COL_COMMENTS ON SYS.ALL_TAB_COLUMNS.COLUMN_NAME = SYS.ALL_COL_COMMENTS.COLUMN_NAME AND SYS.ALL_TAB_COLUMNS.TABLE_NAME = SYS.ALL_COL_COMMENTS.TABLE_NAME AND SYS.ALL_TAB_COLUMNS.OWNER = SYS.ALL_COL_COMMENTS.OWNER
WHERE
SYS.ALL_TAB_COLUMNS.OWNER LIKE '$MY_OWNER'
The result exported to txt file is the script;

I want to fetch all databases and its related tables and columns information. Obviously I can do it from metastore. But I don't have access to it . So is there any other way instead of querying each database one by one.
you'd need python but i did it with this:
databases = run_hive_query('show schemas')
databases = list(databases.database_name)
schema = {'DB':[],
'Table':[],
'Column':[],
'DataType':[]}
for db in databases:
tables = run_hive_query( 'show tables from ' +db)
tables = list(tables.tab_name)
for tb in tables:
try:
columns = (run_hive_query('desc ' + db+'.'+tb))
print(db + ' '+ tb)
except:
print('failed'+db + ' '+ tb)
try:
for x in range(columns.shape[0]):
schema['DB'].append(db)
schema['Table'].append(tb)
schema['Column'].append(columns.iloc[x][0])
schema['DataType'].append(columns.iloc[x][1])
except:
print('failed'+db + ' '+ tb)
You should be able to run the following commands. I guess you could script it up to run across all databases and all tables
SHOW DATABASES;
SHOW TABLES;
DESCRIBE <table_name>;
I have a below SQL query running in one of my project. I am struggling to understand the "as" concept here. In the result "user_key" and "user_all" are appearing as empty. Where as at the front end "user_all" is the combination of "rx.ord_by_userid" + "rx.ord_by_inst_id,"
SELECT rx.rx_id,
rx.pt_visit_id,
rx.pt_id,
pt_visit.date_time_sch,
' ' as print_dea_ind,
' ' as phys_rx_label,
rx.ord_by_userid,
rx.ord_by_inst_id,
' ' as user_key,
pt_visit.visit_inst_id,
' ' as user_all,
' ' as tp_agt_ind,
FROM rx LEFT OUTER JOIN tx_pln ON rx.tp_name = tx_pln.tp_name AND rx.tp_vers_no = tx_pln.tp_vers_no, pt_visit
WHERE ( pt_visit.pt_visit_id = rx.pt_visit_id ) and
( pt_visit.pt_id = rx.pt_id ) and
( ( rx.pt_id = :pt_id ) and
( rx.rx_id = :rx_id ) )
Thanks.
I think when they query database, they need two fields called "user_key" and "user_all" with empty value for some purpose. However, in the front end, they need to display column "user_all" with the combination of "rx.ord_by_userid" + "rx.ord_by_inst_id" because of business rule.
The meaning of "AS" is just setting the alias of any field which is needed to have a new name. In this situation, new columns "user_key" and "user_all" are set with empty value.
AS just provides the field in the data set a name, or in SQL terms, an alias. In PB, this is usually done so that the DataWindow gives it a consistent, easy name. That is all that AS does.
The other part of your mystery is how these get populated with non-blank values. You were assuming this was done in the SQL with AS, but we can assure you that is not the case. Most likely, this value is being set in a script that fires in the client after the Retrieve() (if I were to bet, I'd bet a script on the DataWindow control, maybe RetrieveRow or RetrieveEnd).
I have a quote ID field in a table (PING) that has the following format: "XX" (which is just a lead off to the quote number) followed by the USERID "YYYY" and then the Cart_ID "ZZZZ". Both of the second fields come from another table (Cart). I need to join Cart to the first table. These 2 fields are the only way to join them, but I can't figure out how to join 2 fields to 1 field from another table. Obviously code below won't work, but is for illustration.
join PROD..CART on Cart.CART_ID and Cart.USERID = CW_PING.QuoteID
Try this:
join PROD..CART on CONCAT(Cart.CART_ID,Cart.USERID) = CW_PING.QuoteID
This was the final solution:
join PROD_QQ..CART on 'QQ' + (right('0000000000' + CAST (Cart.USERID as varchar),4) + (right( '0000000000' + CAST (Cart.CART_ID as varchar),6)))
try:
join PROD..CART on [Cart.CART_ID + Cart.USERID] = CW_PING.QuoteID
Morning All,
Im not to sure how i need to solve my following query... I have the following query which pulls back the desired records in SQL server...
SELECT agenda.AgendaItemNumber,Agenda.AgendaName, AgendaType.AgendaTypeDescription, userdetails.fullName
FROM Agenda
JOIN AgendaType ON AgendaType.AgendaTypeID=Agenda.AgendaTypeID
JOIN UserDetails ON Agenda.AgendaID = Userdetails.AgendaID
WHERE agenda.AgendaTypeID = '2'
AND AgendaItemNumber = AgendaItemNumber
AND AgendaName = AgendaName
AND AgendaTypeDescription = AgendaTypeDescription
AND AgendaItemNumber >= '3'
The above query works but i need to enhance this slightly. It pulls back the following results, which essentially are duplicate records except for the 'fullname' column...
What i would like to do is be able to add some extra code to this query so that when i run the query i am able to display one record for each 'AgendaItemNumber' and for it to concat both of the fullnames for this record. However i have additional AgendaItemsNumbers in this table that only have 1 x user fullname assigned to them. its just these few records within the image file i need to do something clever with.
Maybe there is a better way to complete this task?
Many thanks in advance. Any queries please dont hesitate to ask.
Regards
Betty
SELECT agenda.AgendaItemNumber,
Agenda.AgendaName,

The XML extension in SQL-Server allows you to concatenate multiple rows into a single row. The actual intention of the extension is so you can output as XML (obviously), but there are some nifty tricks that are byproducts of the extensions. In the above query, if there were a column name in the subquery (FullName) it would output as <FullName>Joe Bloggs1</FullName><FullName>Joe Bloggs2</FullName>, because there is no column name it simply concatenates the rows (not forming proper XML). The PATH part allows you to specify an additional node, for example if you use PATH('Name') in the above you would get <Name>;Joe Bloggs</Name><Name>;Joe Bloggs2</Name> If you combine Path with a column name you would get Joe Bloggs.
Finally the STUFF just removes the semicolon at the start of the list.
I’m trying to run this SQL using get external.
It works, but when I try to rename the sub-queries or anything for that matter it remove it.
I tried as, as and the name in '', as then the name in "",
and the same with space. What is the right way to do that?
Relevant SQL:
SELECT list_name, app_name,
(SELECT fname + ' ' + lname
FROM dbo.d_agent_define map
WHERE map.agent_id = tac.agent_id) as agent_login,
input, CONVERT(varchar,DATEADD(ss,TAC_BEG_tstamp,'01/01/1970'))
FROM dbo.maps_report_list list
JOIN dbo.report_tac_agent tac ON (tac.list_id = list.list_id)
WHERE input = 'SYS_ERR'
AND app_name = 'CHARLOTT'
AND convert(VARCHAR,DATEADD(ss,day_tstamp,'01/01/1970'),101) = '09/10/2008'
AND list_name LIKE 'NRBAD%'
ORDER BY agent_login,CONVERT(VARCHAR,DATEADD(ss,TAC_BEG_tstamp,'01/01/1970'))
You could get rid of your dbo.d_agent_define subquery and just add in a join to the agent define table.
Would this code work?
select list_name, app_name,
map.fname + ' ' + map.lname as agent_login,
input,
convert(varchar,dateadd(ss,TAC_BEG_tstamp,'01/01/1970')) as tac_seconds
from dbo.maps_report_list list
join dbo.report_tac_agent tac
on (tac.list_id = list.list_id)
join dbo.d_agent_define map
on (map.agent_id = tac.agent_id)
where input = 'SYS_ERR'
and app_name = 'CHARLOTT'
and convert(varchar,dateadd(ss,day_tstamp,'01/01/1970'),101) = '09/10/2008'
and list_name LIKE 'NRBAD%'
order by agent_login,convert(varchar,dateadd(ss,TAC_BEG_tstamp,'01/01/1970'))
Note that I named your dateadd column because it did not have a name. I also tried to keep your convention of how you do a join. There are a few things that I would do different with this query to make it more readable, but I only focused on getting rid of the subquery problem.
I did not do this, but I would recommend that you qualify all of your columns with the table from which you are getting them.
To remove the sub query in the SELECT statement I suggest the following:
SELECT list_name, app_name, map.fname + ' ' + map.lname as agent_login, input, convert(varchar,dateadd(ss, TAC_BEG_tstamp, '01/01/1970))
FROM dbo.maps_report_list inner join
(dbo.report_tac_agent as tac inner join dbo.d_agent_define as map ON (tac.agent_id=map.agent_id)) ON list.list_id = tac.list_id
WHERE input = 'SYS_ERR' and app_name = 'CHARLOTT' and convert(varchar,dateadd(ss,day_tstamp,'01/01/1970'),101) = '09/10/2008'
and list_name LIKE 'NRBAD%' order by agent_login,convert(varchar,dateadd(ss,TAC_BEG_tstamp,'01/01/1970'))
I used parentheses to create the inner join between dbo.report_tac_agent and dbo.d_agent_define first. This is now a set of join data.
The combination of those tables are then joined to your list table, which I am assuming is the driving table here. If I am understand what you are trying to do with your sub select, this should work for you.
As stated by the other poster you should use table names on your columns (e.g. map.fname), it just makes things easy to understand. I didn't in my example because I am note 100% sure which columns go with which tables. Please let me know if this doesn't do it for you and how the data it returns is wrong. That will make it easier to solve in needed.
