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.

I need to insert createdate column twice with two different datatypes one with the datatype defined in the table itself and another in char datatype.
I can insert it by changing the alias name of createdate column but can't insert with same alias name which i need.
so help me out to get correct way of doing it.
My query:
SELECT DISTINCT TE.id, T.debatchqueuelink, TE.transactionlink,
EC.errorclassification, TE.errorvalue,
EC.errorparameter, TE.classificationlink, TE.description,
TE.createdate AS createdate, TO_CHAR(TE.createdate, 'MM/dd/yyyy') AS createdate,
TE.status, TE.rebutt, TE.rebuttedstatus, BQ.appbatchnumber,
BQ.scanbatchnumber, BQ.clientlink, BQ.locationlink, T.patientid,
(DEUD.firstname|| ' ' ||DEUD.lastname) AS deusername, DEUD.email AS deuseremail,
(QCUD.firstname|| ' ' ||QCUD.lastname) AS qcusername, TE.inactive,
TE.decomment
INTO table373
FROM qctransactionerror TE
INNER JOIN errorclassification EC ON EC.id = TE.classificationlink
INNER JOIN qctransaction T ON T.id = TE.transactionlink
INNER JOIN batchqueue BQ ON T.debatchqueuelink = BQ.id
INNER JOIN batchqueue QCBQ ON T.qcbatchqueuelink = QCBQ.id
INNER JOIN userdetail QCUD ON QCBQ.assignedto = QCUD.id
INNER JOIN userdetail DEUD ON BQ.assignedto = DEUD.id
WHERE TE.inactive='t'
AND TE.status IN ('ERROR','QCCORRECTED')
LIMIT 0
The actual error message I am getting is:
Duplicate column:column "createdate" specified more than once
I am converting SQL stored procedure to PostgreSQL stored function. In this stored function inside Update there is From clause.
I want to know how to use From inside Update? Because I am getting error table name "account" specified more than once
CREATE OR REPLACE FUNCTION ETL_Insert_ModifyData( instID numeric)
RETURNS void
LANGUAGE 'sql'
AS $$
--Account
UPDATE account
SET namount = stg_account.namount,
slocation = stg_account.sLocation,
ndept_id = stg_account.ndept_id ,
account.naccount_cpc_mapping_id = stg_account.naccount_cpc_mapping_id
FROM account
INNER JOIN stg_account ON account.naccount_id = stg_account.naccount_id
INNER JOIN department ON stg_account.ndept_id = department.ndept_id
INNER JOIN accountcpcmapping ON stg_account.naccount_cpc_mapping_id = accountcpcmapping.naccount_cpc_mapping_id
WHERE account.ninst_id = instID
AND department.ninst_id = instID
AND accountcpcmapping.ninst_id = instID
--print 'Account completed '
$$
Move the JOIN condition with account table and stg_account to WHERE clause. Also, you need not refer to account in the SET.
Further, prefer shorter aliases (like one or 2 letters) rather than using complete table names.
UPDATE account
SET
namount = stg_account.namount,
slocation = stg_account.sLocation,
ndept_id = stg_account.ndept_id ,
naccount_cpc_mapping_id = stg_account.naccount_cpc_mapping_id
FROM stg_account
INNER JOIN department ON stg_account.ndept_id = department.ndept_id
INNER JOIN accountcpcmapping ON
stg_account.naccount_cpc_mapping_id = accountcpcmapping.naccount_cpc_mapping_id
WHERE account.naccount_id = stg_account.naccount_id
AND account.ninst_id = instID
AND department.ninst_id = instID
AND accountcpcmapping.ninst_id = instID
Trying to insert into a table from other two tables with a loop
DECLARE #RowCount INT
SET #RowCount = (SELECT Max(FogTopicsID) FROM FSB_FogTopics )
DECLARE #I INT
SET #I = 1
WHILE (#I <= #RowCount)
BEGIN
DECLARE #FogID INT, #StudentID INT, #TopicID INT, #ProcessStudentId INT
SELECT #FogID = FogID, #StudentID = StudentID, #TopicID = TopicsID
FROM FSB_FogTopics
WHERE FogTopicsID = #I
SELECT #ProcessStudentId = ProStudentId
FROM FSB_ProcessStudents
WHERE ProcessId = #FogID AND StudentId = #StudentID
INSERT INTO FSB_ProcessTopics( [ProcessStudentId], [TopicId])
VALUES (#ProcessStudentId, #TopicID)
SET #I = #I + 1
END
but I get an error
Must Declare the Scalar Variable #ProcessStudentId
As pointed out by forklift's comment - You can use proper set based solution instead of horrible loop like so;
INSERT FSB_ProcessTopics( [ProcessStudentId], [TopicId])
SELECT
s.ProStudentId,
f.TopicsId
FROM FSB_FogTopics f
INNER JOIN FSB_ProcessStudents s
ON f.FogId = s.ProcessId
AND f.StudentId = s.StudentId
While I realise this doesn't answer your question per-say, this is a better way to do it and should eliminate the need to solve your problem...
You probably have non-continuous Ids - So you have 1,2,4 as Ids but your code is trying to dind 1,2,3,4
You don't need loops to do this (you should almost never need to use loops in SQL for anything). You can do your INSERT in a single statement:
Insert FSB_ProcessTopics
(ProcessStudentId, TopicId)
Select P.ProStudentId, T.TopicsId
From FSB_FogTopics T
Join FSB_ProcessStudents P On P.ProcessId = T.FogId
And P.StudentId = T.StudentId
Do this as a single statement:
INSERT FSB_ProcessTopics(ProcessStudentId, TopicId)
SELECT ProStudentId, TopicsID
FROM FSB_FogTopics ft JOIN
FSB_ProcessStudents ps
ON ft.StudentID = ps.StudentId AND sps.ProcessId = ft.FogiId;
This should replace the cursor, the loop, everything.
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.
I need to delete some rows from table where indexes are equal indexes in table variable
declare #m_table as table
(
number NUMERIC(18,0)
)
...
inserting some rows into #m_table
...
DELETE ct FROM [dbo].[customer_task] ct
inner join project_customer pc on pc.id_customer = #m_table.number
inner join customer_user cu on cu.id_project_customer = pc.id
WHERE ct.id_csr_user = cu.id AND ct.id_status = 1;
but this code generates an error: Must declare the scalar variable "#m_table" How to solve that ?
You probably have a 'GO' (a batch separator) in those '...'
Variable declarations do not span batches.
The error means that SQL is expecting you to treat #m_table like a standard table, rather than a scalar (int, bit, etc.) variable. Perhaps something like this will work?
DELETE ct FROM [dbo].[customer_task] ct
WHERE ct.id_csr_user IN (
SELECT cu.id FROM customer_user cu
INNER JOIN project_customer pc ON pc.id = cu.id_project_customer
WHERE pc.id_customer IN (SELECT number FROM #m_table.number)
) AND ct.id_status = 1;
