SQL Is it possible to incorporate a SELECT with a REPLACE? - sql

I'm using MS SQL Server 2019
I have a string in a table (tblJobCosts) that has its own ID like this:
TextID jobText
1 Total Cost for job is £[]. This includes VAT
How do I update the value stored in the brackets based on the value from another table?
The end result would look like this:
Total Cost for job is £500. This includes VAT
I thought I could incorporate a SELECT with a REPLACE but this does not seem possible:
DECLARE #JobNum INT = 123;
UPDATE dbo.JobCosts
SET jobText = REPLACE (jobText,'[]',
SELECT JH.jobCost
FROM dbo.JobHead AS JH
WHERE (JH.JobNo = #JobNum)
) AND TextID = 1
If I run the above I receive the error:
Incorrect syntax near the keyword 'SELECT'.
Is it possible to incorporate a SELECT with a REPLACE?

I think that you cannot call a select statement in the replace function.
I would try something like that:
UPDATE dbo.JobCosts
SET jobText = REPLACE (jobText,'[]',k.the_cost) from
( SELECT JH.jobCost as the_cost
FROM dbo.JobHead AS JH
WHERE (JH.JobNo = #JobNum)
)k
where TextID = 1

You need to recreate your query and make sure to follow the flow of the clauses properly, please check the next two links to get a better understanding :
[ORA-00936: missing expression tips]
How do I address this ORA-00936 error?
Answer: The Oracle oerr utility notes this about the ORA-00936 error:
ORA-00936 missing expression
Cause: A required part of a clause or expression has been omitted. For example, a SELECT statement may have been entered without a list of columns or expressions or with an incomplete expression. This message is also issued in cases where a reserved word is misused, as in SELECT TABLE.
Action: Check the statement syntax and specify the missing component.
The ORA-00936 happens most frequently:
1 - When you forget list of the column names in your SELECT statement.
2. When you omit the FROM clause of the SQL statement.

I hope this can help you.
You cannot use a simple select query like this. You have to use a PL/SQL block like below -
DECLARE NUM_CNT NUMBER := 0;
BEGIN
SELECT Count(1)
INTO NUM_CNT
FROM wf_item_activity_statuses_v t
WHERE t.activity_label IN ('WAITING_DISB_REQ',
'LOG_DDE',
'LOG_SENDBACK_DDE')
AND t.item_key IN(SELECT r.i_item_key
FROM wf_t_item_xref r
WHERE r.sz_appl_uniqueid = '20400000988');
IF NUM_CNT = 0 THEN
delete
from t_col_val_document_uploaded p
WHERE p.sz_application_no = '20400000988'
AND p.sz_collateral_id = 'PROP000000000PRO1701'
AND p.i_item_key = '648197'
AND p.i_document_srno = '27';
ELSIF NUM_CNT = 1 THEN
DELETE
FROM t_col_val_document_uploaded p
WHERE p.sz_application_no = '20400000988'
AND p.sz_collateral_id = 'PROP000000000PRO1701'
AND p.i_document_srno = '28' )
END IF;
END;

DB2 SQL function returning multiple values when I am expecting only one

I am trying to get the location of the last time an item was moved via sql function with the code below. Pretty basic, I'm just trying to grab the max date and time. If I run the sql as a regular select and hard code an item number in ATPRIM I get only one location. But if I create this function and then try to run it and then pass the function an item number I get every occurrence in the history file instead of just the MAX which would be the most recent. Also I have tried a Select Distinct and that did not do anything for me.
ATOGST = Item Location
ATPRIM = Item
ATDATE = Date
ATTIME = Time
CREATE FUNCTION ERPLXU/F#QAT1(AATPRIM VARCHAR(10))
RETURNS CHAR(50)
LANGUAGE SQL
NOT DETERMINISTIC
BEGIN DECLARE F#QAT1 CHAR(50) ;
SET F#QAT1 = ' ' ;
SELECT ATOGST
INTO F#QAT1 FROM ERPLXF/QAT as t1
WHERE ATPRIM = AATPRIM
AND ATDATE = (SELECT MAX(ATDATE) FROM ERPLXF/QAT AS T2
WHERE T2.ATPRIM = AATPRIM)
AND ATTIME = (SELECT MAX(ATTIME) FROM ERPLXF/QAT AS T3
WHERE T3.ATPRIM = AATPRIM
AND T3.ATDATE = T1.ATDATE) ;
RETURN F#QAT1 ;
END
EDIT:
So what I am trying to do is get that location and I got it to work on my iSeries in strsql but the problem is we use a web application called Web Object Wizard (WoW) which lets us use sql to make reports that are more user friendly. Below is what I was trying to get to work but the subquery in the select does not work in WoW so that is where I was trying create a function which we know works in other applications.
SELECT distinct t1.atprim, atdesc, dbtabl, dbdtin, dblife, dblpdp,
dbcost, dbbas, dbresv, dbyrdp, dbcurr,
(select atogst
from erplxf.qat as t2
where t1.atprim = t2.atprim and atdate = (select max(atdate) from
erplxf.qat as t3 where t2.atprim = t3.atprim) and attime = (select
max(attime) from erplxf.qat as t4 where t1.atprim = t4.atprim and
t1.atdate = t4.atdate)
) as #113_ToLoc
FROM erplxf.qat as t1 join erplxf.qdb on atassn = dbassn
where dbrcid = 'DB'
and dbcurr != 0
So instead of that subquery at the end of the select it would just be
, erplxu.f#qat1(atprim) as #113_ToLoc
Try this:
CREATE FUNCTION ERPLXU/F#QAT1(AATPRIM VARCHAR(10))
RETURNS CHAR(50)
LANGUAGE SQL
RETURN
SELECT ATOGST
FROM ERPLXF/QAT
WHERE ATPRIM = AATPRIM
ORDER BY ATDATE DESC, ATTIME DESC
FETCH FIRST 1 ROW ONLY;

How to get rid of Cursor and use UPDATE with SELECT

I believe that the cursor used in this code is the reason for some major performance issues, however I am new to TSQL.
Following script runs on SQL SERVER 2008. I am trying to redo it so I use JOIN statements instead, however I have not been able to do so successfully.
DECLARE AIRAMSDET CURSOR FOR
SELECT BILL, RECIEPT, NAME
FROM Client_Table
WHERE IsProcessed = 1
AND TYPE IN ('Sub','First_Time','Old') AND LEN(BILL) > 1
OPEN AIRAMSDET
FETCH AIRAMSDET into #VARBILL, #VARRECIEPT, #VARNAME
WHILE ##Fetch_Status = 0
BEGIN
UPDATE archieve
SET entry = left(#VARBILL + '- '+ #VARNAME)
WHERE archiveID = #VARBILL
END
It should be something like following
UPDATE ARCHIEVE
SET ENTRY = CT.BILL + '-' + CT.NAME
FROM CLIENT_TABLE CT
WHERE
ARCHIEVE.ARCHIVEID = CT.BILL
AND CT.ISPROCESSED = 1
AND CT.TYPE IN ('Sub','First_Time','Old') AND LEN(BILL) > 1
I have not included LEFT() as its use in your query wasn't very clear. Left takes an integer_expression as its second parameter while you are passing ##VARNAME which most likely is a VARCHAR. Please add that as you deem fit.

Oracle SQL Adding IF statement

I have a pretty simple question me thinks. I've been looking on the internet, but haven't been able to find anything. I am trying to add an IF statement basically to my Oracle sql.
UPDATE PS_Z_TREND_NOW_TBL a
SET STATUS = (
SELECT COUNT(SEC.IS_AW_AUTH_NAME)
FROM PS_IS_AW_SECURITY sec
WHERE sec.IS_AW_AUTH_NAME LIKE '%Manager%'
I want to update STATUS so that if COUNT(SEC.IS_AW_AUTH_NAME) is greater than 0 it will insert 'M'. How would I write this?
With Case statements.
UPDATE PS_Z_TREND_NOW_TBL a
SET STATUS = ( CASE WHEN COUNT(SEC.IS_AW_AUTH_NAME) > 0 then 'M'
ELSE null END )
FROM PS_IS_AW_SECURITY sec
WHERE sec.IS_AW_AUTH_NAME LIKE '%Manager%'

conditional handling of update sql script depending on input parameter

I am new to SQL and using Oracle 11. I need to write a sql script which uses different update command based on whether the input param is null or not null.
I need something like this
['&' followed by the parameter name is the way i see parameters being used in other such
script for our project]
IF &PRG_ID IS NULL
UPDATE PROGRAM_TABLE P SET HANDLED_IND = 'Y' WHERE EXISTS
(SELECT 1 FROM HANDLED_PROGRAM H WHERE H.PROGRAM_ID = P.PROGRAM_ID);
ELSE
UPDATE PROGRAM_TABLE P SET HANDLED_IND = 'Y' WHERE
P.PROGRAM_ID = &PRG_ID AND EXISTS
(SELECT 1 FROM HANDLED_PROGRAM H WHERE H.PROGRAM_ID = P.PROGRAM_ID);
END IF;
Something like (is not tested):
UPDATE PROGRAM_TABLE P SET HANDLED_IND = 'Y' WHERE EXISTS
(SELECT 1 FROM HANDLED_PROGRAM H WHERE H.PROGRAM_ID = P.PROGRAM_ID)
AND (&PRG_ID IS NULL OR P.PROGRAM_ID = &PRG_ID);
But take into account this change may lead to the performance degradation for the case when PRG_ID has definite value.
