This is the MySQL query, now I need this below dynamic query to execute in TERADATA SQL.
set l_sql=concat('SELECT max(',l_rid_col,'), MAX(cid) INTO #c2, #c3 FROM ',p_database,'.',p_table);
SET l_rid = #c2;
SET l_cid = #c3;
And this update query:
update table_a
set row = ifnull(l_rid, 0),
column = ifnull(l_cid, 0)
where databasename = p_database
and tablename = p_table;
But In Teradata I tried this way:
update table_a as a
from (select max(l_rid) TR, MAX(l_cid) TCC
from DEVP.employees) as b
set a.row = b.TR, a.column = b.TCC
where a.databasename = 'DEVP'
and a.tablename = 'employees';
Please remove the alias name from the LHS of the update statement.
a.colA=b.colname should be colA=b.colname
I got the answer:
update table_a from (select max(l_rid) TR, MAX(l_cid) TCC from DEVP.employees )as b
set row= b.TR , column=b.TCC where databasename='DEVP' and tablename='employees';
ISSUE: I just removed the alias name in UPDATE. finally got it.

I am trying to update data in Table: local.import_payments from Table: local.payments based on update and Inner Join queries. The query I used:
Update local.import_payments
Set local.import_payments.client_id = local.payments.payment_for_client__record_id,
local.import_payments.client_name = local.payments.payment_for_client__company_name,
local.import_payments.customer_id = local.payments.customer__record_id,
local.import_payments.customer_name = local.payment_from_customer,
local.import_payments.payment_id = local.payments.payment_id
From local.import_payments
Inner Join local.payments
Where local.payments.copy_to_imported_payments = 'true'
The client_id, client_name, customer_id, customer_name in the local.import_payments need to get updated with the values from the table local.payments based on the condition that the field copy_to_imported_payments is checked.
I am getting a syntax error while executing the query. I tried a couple of things, but they did not work. Can anyone look over the queries and let me know where the issue is
Try the following
UPDATE local.import_payments
Set local.import_payments.client_id =
local.payments.payment_for_client__record_id,
local.import_payments.client_name =
local.payments.payment_for_client__company_name,
local.import_payments.customer_id = local.payments.customer__record_id,
local.import_payments.customer_name = local.payment_from_customer,
local.import_payments.payment_id = local.payments.payment_id
FROM local.payments as lpay
WHERE lpay.<<field>> = local.import_payments.<<field>>
AND local.payments.copy_to_imported_payments = 'true'
You shouldn't to specify the schema/table for updated columns, only column names:
Do not include the table's name in the specification of a target column — for example, UPDATE table_name SET table_name.col = 1 is invalid.
from the doc
You shouldn't to use the updating table in the from clause except of the case of self-join.
You can to make your query shorter using "column-list syntax".
update local.import_payments as target
set (
client_id,
client_name,
customer_id,
customer_name,
payment_id) = (
source.payment_for_client__record_id,
source.payment_for_client__company_name,
source.customer__record_id,
source.payment_from_customer,
source.payment_id)
from local.payments as source
where
<join condition> and
source.copy_to_imported_payments = 'true'
I have History table and transaction table.....and reference table...
If status in reference table is CLOSE then take those record verify in History table if not there insert from transaction table..... wiring query like this .... checking better one... please advice.. this query can be used for huge data ?
INSERT INTO LIB1.HIST_TBL
( SELECT R.ACCT, R.STATUS, R.DATE FROM
LIB2.HIST_TBL R JOIN LIB1.REF_TBL C
ON R.ACCT = C.ACCT WHERE C.STATUS = '5'
AND R.ACCT NOT IN
(SELECT ACTNO FROM LIB1.HIST_TBL)) ;
If you're on a current release of DB2 for i, take a look at the MERGE statement
MERGE INTO hist_tbl H
USING (SELECT * FROM ref_tbl R
WHERE r.status = 'S')
ON h.actno = r.actno
WHEN NOT MATCHED THEN
INSERT (actno,histcol2, histcol3) VALUES (r.actno,r.refcol2,r.refcol3)
--if needed
WHEN MATCHED
UPDATE SET (actno,histcol2, histcol3) = (r.actno,r.refcol2,r.refcol3)
Hi i am new to oracle_sqldeveloper can you please give me the answer how to know the table structure and relationships of a database.
You can try
DESC <table_name>
Try this:
select table_name, column_name, data_type
from all_tab_columns
where table_name = <TABLE_NAME_HERE>
and owner = '<YOUR_USER_HERE_IN_CAPITAL_LETTERS>'
If you have comments on your table then to get columns' comments:
select tc.table_name, tc.column_name, tc.data_type, cc.comments
from all_col_comments cc, all_tab_columns tc
where tc.table_name = <TABLE_NAME_HERE>
and tc.owner = <OWNER_OF_TABLE_HERE>
and tc.table_name = cc.table_name
and tc.column_name = cc.column_name
and tc.owner = cc.owner
If you are logged in under owner of the table you can write this:
select table_name, column_name, data_type
from user_tab_columns
where table_name = <TABLE_NAME_HERE>
or to get columns with comments
select tc.table_name, tc.column_name, tc.data_type, cc.comments
from user_col_comments cc, user_tab_columns tc
where tc.table_name = '<TABLE_NAME_HERE>'
and tc.owner = '<YOUR_USER_HERE_IN_CAPITAL_LETTERS>'
and tc.table_name = cc.table_name
and tc.column_name = cc.column_name
To get relationships between tables user this query:
select uc1.table_name
, uc1.constraint_name
, cc1.column_name
, uc2.table_name r_table_name
, uc2.constraint_name r_constraint_name
, cc2.column_name r_column_name
from all_constraints uc1
, all_constraints uc2
, all_cons_columns cc1
, all_cons_columns cc2
where 1 = 1
and uc2.constraint_type = 'R'
and uc1.constraint_name = uc2.r_constraint_name
and cc1.table_name = uc1.table_name
and cc1.constraint_name = uc1.constraint_name
and cc2.table_name = uc1.table_name
and cc2.constraint_name = uc1.constraint_name
and uc1.owner = '<YOUR_USER_HERE_IN_CAPITAL_LETTERS>'
and uc2.owner = uc1.owner
and cc1.owner = uc1.owner
and cc2.owner = uc1.owner
order by 1
/
Columns with the "R_" prefix mean that they are foreign data (they represent foreign keys). As you can see, I used the tables with the "ALL_" prefix, to use similar tables with the "USER_" prefix, get rid of the "OWNER" section.
To know more about oracle data dictionary read this
1) type your table name.
2) right click on table name & click Open Declaration.
There are two update queries and 1st update query execute successfully but 2nd update query is not execute and show the following message:
Msg 512, Level 16, State 1, Line 10
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression. The statement has been terminated.
1st update query:
update dbo.TblPrePostApproval
set
dbo.TblPrePostApproval.PAApprovedDate = (select dbo.TblMasterInfo.AppRefDate
from dbo.TblMasterInfo
Where dbo.TblMasterInfo.Appid = dbo.TblPrePostApproval.Appid),
dbo.TblPrePostApproval.PAApprovedTenor = '36',
dbo.TblPrePostApproval.PAApprovedAmt = (select dbo.TblMasterInfo.AppReqeustAmt

2nd update query

dbo.TblPrePostApproval.PADisbBr = (select dbo.TestPost.PABr
from dbo.TestPost
where dbo.TestPost.Appid = dbo.TblPrePostApproval.AppID)
Where is my problem? Pls any one suggest me.
One of your subqueries (I guess on line 10) is returning more than one row, so it can't check to see if it equals anything, because it's a set, not a value. Just change your query to be more specific. Try adding LIMIT 0, 1 to the end of the subqueries, or TOP (1) after the the SELECT in each subquery.
Why don't you use JOINs for your update? Much easier to read and understand!
Query #1:
UPDATE ppa
SET
PAApprovedDate = info.AppRefDate,
PAApprovedTenor = '36',
PAApprovedAmt = info.AppReqeustAmt,
PADisbBr = info.AppSourceBrName
FROM
dbo.TblPrePostApproval ppa
INNER JOIN
dbo.TblMasterInfo.TblMasterInfo info ON info.Appid = ppa.Appid
Query #2:
UPDATE ppa
SET
PAApprovedDate = tp.PADate,
PAApprovedTenor = tp.PATenor,
PAApprovedAmt = tp.PAAmt,
PADisbBr = tp.PABr
FROM
dbo.TblPrePostApproval ppa
INNER JOIN
dbo.TestPost tp ON tp.Appid = ppa.AppID
Here is my situation. I know there must be a simple answer, but I am just not well versed in TSQL to know how. Below I have the main query of a stored procedure that selects the data I need. I have it working so far except that I need to call a seperate stored procedure called GetRecordMediaById where I feed it the Id from the PhotoId column, and it selects the BLOB data from the appropriate database which then needs to be its own column in the final query or replace the original PhotoId column.
I have no clue how to go about this. I've tried implementing temp tables, but I could never even get it to execute.
Here is my code:
ALTER PROCEDURE [dbo].[GetRollCallData]
#Ids VARCHAR(255),
#LexiconId INT,
#UUID UNIQUEIDENTIFIER,
#ReadOnly INT
AS
DECLARE #TableCode INT
SET #TableCode = 58
EXEC InsertInSelectionCache #Ids, #UUID, #TableCode, 0
WITH DOACTE AS(
SELECT ROW_NUMBER() OVER(PARTITION BY [File].Id ORDER BY CustomRecordsetId DESC) AS RowNumber, [File].*, FileType2Lexicon.Label as FileTypeLabel, [People].DefaultPhone, [People].InvertedName, CustomFieldValue.Value as DateofArrest
FROM FileType2Lexicon, SelectionCache, [People], [File]
INNER JOIN [CustomRecordSet]
ON [CustomRecordset].RecordId = [File].Id
INNER JOIN CustomFieldValue
ON [CustomRecordset].Id = CustomFieldValue.CustomRecordsetId
INNER JOIN [CustomField2Lexicon]
ON CustomField2Lexicon.CustomFieldId = CustomFieldValue.CustomFieldId
WHERE [File].Id = SelectionCache.RecordId
AND SelectionCache.UUID = #UUID
AND SelectionCache.TableCode = #TableCode -- this is the code for File table
AND [File].Id <> 0
AND [File].FileTypeId = FileType2Lexicon.FileTypeId
AND FileType2Lexicon.LexiconId = #LexiconId
AND [File].ClientIdString = [People].ClientIdString
AND CustomFieldValue.Value <> ''
AND CustomField2Lexicon.Label = 'Date of Arrest'),
PHOTOCTE AS(
SELECT [File].Id, CustomFieldValue.Value as PhotoId
FROM FileType2Lexicon, SelectionCache, [People], [File]
INNER JOIN [CustomRecordSet]
ON [CustomRecordset].RecordId = [File].Id
INNER JOIN CustomFieldValue
ON [CustomRecordset].Id = CustomFieldValue.CustomRecordsetId
INNER JOIN [CustomField2Lexicon]
ON CustomField2Lexicon.CustomFieldId = CustomFieldValue.CustomFieldId
WHERE [File].Id = SelectionCache.RecordId
AND SelectionCache.UUID = #UUID
AND SelectionCache.TableCode = #TableCode -- this is the code for File table
AND [File].Id <> 0
AND [File].FileTypeId = FileType2Lexicon.FileTypeId
AND FileType2Lexicon.LexiconId = #LexiconId
AND [File].ClientIdString = [People].ClientIdString
AND CustomFieldValue.Value <> ''
AND CustomField2Lexicon.Label = 'Booking Photo')
SELECT DOACTE.*, PHOTOCTE.PhotoId
FROM DOACTE
INNER JOIN
PHOTOCTE
ON DOACTE.Id = PHOTOCTE.Id
WHERE DOACTE.RowNumber = 1
EDIT:
Solution for me was to create a scalar function that resolves the Id in the BLOB database and returns the BLOB data.
SELECT DOACTE.*, dbo.GetImagebyId(PHOTOCTE.PhotoId) as Photo,
FROM DOACTE
INNER JOIN
PHOTOCTE
ON DOACTE.Id = PhotoCTE.Id
WHERE DOACTE.RowNumber = 1
You can declare a #table_variable and insert the results from "EXEC InsertInSelectionCache #Ids, #UUID, #TableCode, 0" into the table variable.
Then you can join to the #table_variable in the final query.
