How to use IF statement inside WITH? - sql

Wasn't able to find a proper example of this (or maybe I am simply looking in wrong direction).
Depending on incoming parameter value I need to change WHERE condition for SELECT.
For example, I got parameter #bookType with value 'All' and I need to make something like this:
IF #bookType = 'All'
SELECT * FROM tBooks
WHERE BookType != 'Template' AND BookGroup='Library'
ELSE
SELECT * FROM tBooks
WHERE BookType = #bookType AND BookStatus=#bookStatus
Seems simple, but I need this IF inside WITH:
WITH Books AS (
IF...
...
), bookIds AS (
...
...
)
And this is not working because I am starting to receive 'Incorrect syntax near IF'. What exactly I am doing wrong? Or maybe it is possible to hide this IF inside WHERE statement (change where depending on parameter value)?

;
WITH Books AS (
SELECT * FROM tBooks
WHERE
(#BookType = 'All' AND BookType != 'Template' AND BookGroup='Library')
OR
(#BookType <> 'All' AND BookType = #bookType AND BookStatus=#bookStatus)
)

How to make LIKE behave case-insensitive?

I have an importedParameter which I want to search inside of a column in a SELECT.
But for now it is case-sensitive, how can I make it case-insensitive ?
I've tried multiple things: AND LOWER(columnName) LIKE LOWER(#lv_string) or AND columnName LIKE #tst_string COLLATE utf8_general_ci and some other stuff but got this error:
A Boolean expression is required in positions starting with LOWER(Q.
Sample code:
DATA(tst_string) = '%' && importedParamter && '%'.
IF anotherParameter IS NOT INITIAL.
IF importedParamter IS NOT INITIAL.
SELECT * FROM <table1> as p
INNER JOIN <table2> as q on q~column1 = p~column1
WHERE p~column2 = #anotherParameter
AND q~column2 LIKE #tst_string
INTO CORRESPONDING FIELDS OF TABLE #anotherName
ENDIF.
ENDIF.
I believe Regex is your preferred choice: LIKE_REGEXPR:
SELECT *
FROM <table1> as p
INNER JOIN <table2> as q on q~column1 = p~column1
WHERE p~column2 = #anotherParameter
AND like_regexpr( pcre = '\bparam\b', value = q~column2, CASE_SENSITIVE = 'X' ) = '1'
INTO TABLE DATA(#anotherName).
It has CASE_SENSITIVE predicate which respects (or not) the case.
Though this is available only since ABAP 7.55, so on lower releases you are out of the luck.
This code works fine for me:
SELECT *
FROM adrp
WHERE LOWER( name_first ) LIKE 'phi%'
INTO TABLE #DATA(results).
It finds my personal data entry (as well as those of another "Philipp" and of a "Philip"), even though we are all spelled with a capital P.
LIKE LOWER( 'Phi%' ) does not work, but when you can't control the input, then you can convert it to lower case before the select:
DATA(tst_string) = 'Phi%'.
TRANSLATE tst_string TO LOWER CASE.
SELECT *
FROM adrp
WHERE LOWER( name_first ) LIKE #tst_string
INTO TABLE #DATA(results).
Release: 7.54
I am not sure which release specifically allowed functions like LOWER within the WHERE clause. According to the comments, it should work since 7.51.

change where condition based on column value

I faced the following requirement. The following query is called by a procedure. The value p_pac_code is the input parameter of the procedure.
The requirement is the query should have an additional condition sp_sbsp.SUBSPCLTY_CODE!='C430 if the p_pac_code value is '008'.
For any other p_pac_code value, it should run as it is below. Is there way to do this by adding an additional condition in the WHERE clause?
As for now, I have done this using IF.....ELSE using the query two times separately depending on p_pac_code value. But I am required to find a way to do with just adding a condition to this single query.
SELECT ptg.group_cid
FROM PRVDR_TYPE_X_SPCLTY_SUBSPCLTY ptxss,
PT_X_SP_SSP_STATUS pxsst ,
pt_sp_ssp_x_group ptg,
group_x_group_store gg,
specialty_subspecialty sp_sbsp,
treatment_type tt,
provider_type pt
WHERE
pt.PRVDR_TYPE_CODE = ptxss.PRVDR_TYPE_CODE
AND tt.TRTMNT_TYPE_CODE = pxsst.TRTMNT_TYPE_CODE
AND ptxss.PRVDR_TYPE_X_SPCLTY_SID = pxsst.PRVDR_TYPE_X_SPCLTY_SID
AND tt.TRTMNT_TYPE_CODE = p_pac_code
AND TRUNC(SYSDATE) BETWEEN TRUNC(PXSST.FROM_DATE) AND TRUNC(PXSST.TO_DATE)
AND ptg.prvdr_type_code =ptxss.prvdr_type_code
AND ptg.spclty_subspclty_sid = ptxss.spclty_subspclty_sid
AND ptxss.spclty_subspclty_sid = sp_sbsp.spclty_subspclty_sid
AND ptg.spclty_subspclty_sid = sp_sbsp.spclty_subspclty_sid
AND ptg.status_cid = 2
AND ptg.group_cid = gg.group_cid
AND gg.group_store_cid = 16
AND gg.status_cid = 2;
Thanks in advance.
You can simply add a condition like this:
... and (
( sp_sbsp.SUBSPCLTY_CODE!='C430' and p_pac_code = '008')
OR
NVL(p_pac_code, '-') != '008'
)
This can be re-written in different ways, this one is quite self-explanatory
Just add:
AND NOT ( NVL( sp_sbsp.SUBSPCLTY_CODE, 'x' ) = 'C430'
AND NVL( p_pac_code value, 'x' ) = '008' )
to the where clause.
The NVL function is used so that it will match NULL values (if they exist in your data); otherwise, even though NULL does not match C430 you will still find that NULL = 'C430' and NULL <> 'C430' and NOT( NULL = 'C430' ) will all return false.
Quite easy. Add the following condition:
AND (sp_sbsp.SUBSPCLTY_CODE != 'C430' OR p_pac_code value != '008')
(don't forget the parenthesis)
Just sharing
SELECT ptg.group_cid
FROM PRVDR_TYPE_X_SPCLTY_SUBSPCLTY ptxss
WHERE
pt.PRVDR_TYPE_CODE = ptxss.PRVDR_TYPE_CODE
&&((tt.TRTMNT_TYPE_CODE = pxsst.TRTMNT_TYPE_CODE)
or (tt.TRTMNT_TYPE_CODE = pxsst.TRTMNT_TYPE_CODE))
just use the parenthesis to specify where the conditionmust implement.

CASE in WHERE clause returns Error

I'm running this code:
SELECT hID
FROM logonsHistory
WHERE aIDs NOT LIKE '%''101''%' AND
CASE src
WHEN 0 THEN
uID IN(29,41,42,45,49,50,57,73,83,107,166,349,356,367,375,376,416,471,472,473,474,481)
END
I get this error:
Incorrect syntax near the keyword 'IN'
I have no idea what's wrong.
A CASE statement is not appropriate in this case. Just use a simple OR condition:
SELECT hID
FROM logonsHistory
WHERE aIDs NOT LIKE '%''101''%'
AND (
src <> 0 -- add a COALESCE here if src can be NULL
OR uID IN(29,41,42,45,49,50,57,73,83,107,166,349,356,367,375,376,416,471,472,473,474,481)
)
... which basically is the equivalent of only applying the uID filtering if src = 0, which is what you appeared to be trying to accomplish with your query.
It sounds like you don't have to use CASE please test this
SELECT hID
FROM logonsHistory
WHERE aIDs NOT LIKE '%''101''%'
AND ( (src = 0 --scr is 0 => must have uid in the list
AND UID IN (29,41,42,45,49,50,57,73,83,107,166,349,356,367,375,376,416,471,472,473,474,481))
OR src <> 0) --else src is not 0 and there is no additional condition
i have a doubt on your not like condition have you tested it alone?
Guess this is what you are looking for
WHERE aIDs NOT LIKE '%''101''%' or
(
src = 0
AND
uID IN(29,41,42,45,49,50,57,73,83,107,166,349,356,367,375,376,416,471,472,473,474,481
)
It looks like your statement is not formatted properly. you placed a condition rather than a value to set within "When 0 then ...... END
the uID IN(29,41,42,45,49,50,57,73,83,107,166,349,356,367,375,376,416,471,472,473,474,481) you have there is a condition and shouldn't have been there
The when part of a case statement should select a single value. what you are trying to do is to check for a condition.
Or if you are checking for uid in those values, you should do
case when src = 0 then
case when uID IN (29,41,42,45,49,50,57,73,83,107,166,349,356,367,375,376,416,471,472,473,474,481)
then 'It is a Client ID'
-- add another when or else part here if required
end
else 'Not a UID and not a Client ID'
end

How to give change working of having function dynamicaly on executing an sql statement?

I'm having a Sql code like as follows
Select a.ItemCode, a.ItemDesc
From fn_BOM_Material_Master('A', #AsOnDate, #RptDate, #BranchID, #CompID)a
Left Outer Join fn_INV_AsOnDate_Stock(#StockDate, #AsOnDate, #RptDate, #BranchID, #CompID, #Finyear)b
On a.ItemCode=b.ItemCode and b.WarehouseCode<>'WAP'
and a.BranchID=b.BranchID and a.CompID=b.COmpID
Where a.ItemNatureCode = 'F' and a.BranchID = #BranchID and a.CompID = #CompID
Group by a.ItemCode, a.ItemDesc
Having sum(b.CBQty)<=0
Here the problem is that im passing an "#ShowZeroStock" value as as bit if the "#ShowZeroStock" value is '1' then Having should not be validated or (i.e: All values from the table should be returned including zero)
So How to change the query based on passed bit value "#ShowZeroStock"
I can Use "If else " condition at the top and remove having in else part, but for a lengthy query i can't do the same.
Is this the logic you want?
Having sum(b.CBQty) <= 0 or #ShowZeroStock = 1

Dynamic appending constraints in SQL query

I have this SQL
SELECT devudp1.deviceoid,devudp1.valueType
FROM DeviceUdpValues devUDP1
WHERE devudp1.udpname='TestUDP'
and <<either bdvalue or string value based on user selected value datatype>>
Here in the Query based on the devudp1.valueType I want to append below attribute
If the valueType is 3 then I want to append my above select clause with devudp1.bdvalue ='10', else it should be appended by devudp1.bdvalue = 'Hello'
So the above query when valueType is 3 will look like
SELECT devudp1.deviceoid,devudp1.valueType
FROM DeviceUdpValues devUDP1
WHERE devudp1.udpname='TestUDP'
AND devudp1.bdvalue = '10'
else it will look like
SELECT devudp1.deviceoid,devudp1.valueType
FROM DeviceUdpValues devUDP1
WHERE devudp1.udpname='TestUDP'
AND devudp1.stringValue = 'Hello'
Can anyone suggest me how to put this logic in place
Try this:
SELECT devudp1.deviceoid,devudp1.valueType
FROM DeviceUdpValues devUDP1
WHERE devudp1.udpname='TestUDP'
AND (
(<USER-SELECTED-VALUE> = 3 AND devudp1.bdvalue ='10') OR
(<USER-SELECTED-VALUE> <> 3 AND devudp1.stringvalue ='Hello')
)
