I am trying to concatenate several columns of a person's name into one column and ultimately into a temporary table. I am unable to get the ISNULL function to work correctly.
I have tried using ISNULL to effectively say "if this column is blank, then just ignore it". I've read about a command called ISBLANK but that doesn't seem to work on my version of SQL Server.
SELECT
co.serialnumber, co.envelopesalutation,
co.title + ' ' + LEFT(co.firstname, 1) + ' ' + ISNULL(LEFT(co.otherinitial, 1), '') +
' ' + co.keyname + ' ' + ISNULL(co.POSTNOMINAL, '') [Correct]
INTO
TEMPENVSALUTATION
FROM
contact co
WHERE
co.contacttype = 'Individual'
AND co.title IN ('Mr', 'Mrs', 'Ms', 'Miss', 'Mx', 'Dr')
I expect, for example, that someone with co.title of Mr, a co.firstname of Jon, no co.otherinitial a co.keyname of Smith and no co.postnominal to appear in the TEMPENVSALUTATION table as Mr J Smith
What I'm actually getting is only people who have a co.otherinitial appearing e.g. Mr S D Smith.

I am looking to subtract two string columns from another string column.
I have acheived this in the past in Oracle using the below
SELECT
C.MANUFACTURER,
C.MODEL_GROUP,
REGEXP_REPLACE(C.VARIANT, '^'||C.MANUFACTURER || ' +' || C.MODEL_GROUP) "VAR DESC",
C.VARIANT
FROM STD_BI.RL2_CONTRACTS_VW C
I now need to acheive the same in MS SQL any suggestions would be appreciated.
"Subtract" is surely a misnomer here. The OP appears to want to remove a string at the beginning of another string.
From this point on, I am assuming that MANUFACTURER and MODEL_GROUP do not contain any regular expression wildcard characters.
There is a challenge with multiple spaces. If there are not too many, then you can do. For instance, this handles one or two spaces:
SELECT C.MANUFACTURER, C.MODEL_GROUP,
(CASE WHEN C.VARIANT LIKE C.MANUFACTURER + ' ' + C.MODEL_GROUP + '%'
THEN STUFF(C.VARIANT, 1, LEN(C.MANUFACTURER + ' ' + C.MODEL_GROUP), '')
WHEN C.VARIANT LIKE C.MANUFACTURER + ' ' + C.MODEL_GROUP + '%' AND
THEN STUFF(C.VARIANT, 1, LEN(C.MANUFACTURER + ' ' + C.MODEL_GROUP), '')
ELSE C.VARIANT
END) as [VAR DESC],
C.VARIANT
FROM STD_BI.RL2_CONTRACTS_VW C;
EDIT:
Here is a more complete solution:
SELECT C.MANUFACTURER, C.MODEL_GROUP,
(CASE WHEN C.VARIANT LIKE C.MANUFACTURER + ' %' + C.MODEL_GROUP + '%' AND
C.VARIANT NOT LIKE C.MANUFACTURER + ' %[^ ]%' + C.MODEL_GROUP + '%'
THEN STUFF(LTRIM(STUFF(C.VARIANT, 1, LEN(C.MANUFACTURER), '')), 1, LEN(C.MODEL_GROUP), '')
ELSE C.VARIANT
END) as [VAR DESC],
C.VARIANT
FROM STD_BI.RL2_CONTRACTS_VW C;
This tests for just spaces between the two strings (the not like is checking for something other than a space). The replacement is then in three steps -- remove the manufacturer, then the spaces, then the model group.
I have spent some time on this one as much for my own satisfaction and in addition to the answer above, I have come up with the following which also generates the correct answer.
SUBSTRING(FV.VARIANT, LEN(FV.MANUFACTURER + ' ' + FV.MODEL_RANGE + ' ') + 1 , LEN(FV.VARIANT))
My problem was kinda easier to solve, I just needed to remove "xxxx" (the first 4 characters) at the start of a column from some rows:
UPDATE coluna SET columToEdit = SUBSTRING(columToEdit, 5, 200);
I am trying to build a distinct string in a query, which works unless one of the values is NULL. I've tested removing LOCATION_ADDR_LINE_2, and the query will work just fine. When I do not SELECT DISTINCT, I find that LOCATION_ADDR_LINE_2 values are NULL. How can I gather these values in the SELECT DISTINCT even if NULL?
SELECT DISTINCT(LOCATION_ADDR_LINE_1 + ', ' + LOCATION_ADDR_LINE_2 + ', ' + LOCATION_CITY + ', ' + LOCATION_WORK_STATE) AS Addresses
FROM OracleReport
WHERE (LOCATION_ADDR_LINE_1 LIKE '%1135 Auto%' OR LOCATION_ADDR_LINE_1 LIKE '%199 Easy%')
Returns:
Addresses
NULL
SELECT DISTINCT(LOCATION_ADDR_LINE_1 + ', ' + LOCATION_CITY + ', ' + LOCATION_WORK_STATE) AS Addresses
FROM [OperationReport].[dbo].[OracleReport]
WHERE (LOCATION_ADDR_LINE_1 LIKE '%1135 Auto%' OR LOCATION_ADDR_LINE_1 LIKE '%199 Easy%')
Returns:
Addresses
1135 Auto...
189-199 Easy...
Assuming you don't mind text,,text,... (empty string) when a value is NULL...
SELECT DISTINCT(coalesce(LOCATION_ADDR_LINE_1,'') + ', ' +
coalesce(LOCATION_ADDR_LINE_2,'') + ', ' +
coalesce(LOCATION_CITY,'') + ', ' +
coalesce(LOCATION_WORK_STATE,'')) AS Addresses
FROM OracleReport
WHERE (LOCATION_ADDR_LINE_1 LIKE '%1135 Auto%'
OR LOCATION_ADDR_LINE_1 LIKE '%199 Easy%')
Coalesce will take the first non-null value and return it. It requires consistent data types and will early exit once the first non-null value in a series is encountered. (more details Oracle Differences between NVL and Coalesce)
I have a stored procedure that is getting information from my employee table and returning the data.
There are 3 columns that are used:
B.[SiloDesc] + ' (' + B.[TitleDesc] + ') ' + B.[SkillSetDesc] as SkillSetDesc,
My issue is, if one of those happens to be null, it wont display any of the data. What is the best way to have it include the data regardless of if one of those fields are null.
You could use coalesce() or isnull() for each individual column... or you could simply use...
CONCAT ( string_value1, string_value2 [, string_valueN ] )
Takes a variable number of string arguments and concatenates them into a single string. It requires a minimum of two input values; otherwise, an error is raised. All arguments are implicitly converted to string types and then concatenated. Null values are implicitly converted to an empty string.
A.: Remove the parentheses when TitleDesc is null:
select concat(B.[SiloDesc], ' (' + B.[TitleDesc] + ')', ' ' + B.[SkillSetDesc])
Because of the way null is treated in sql, the expression ' (' + null + ')' results in null which concat() will treat as an empty string... which is kind of nice as it effectively removes the parentheses if the value is null.
B.: Keep the parentheses regardless:
select concat(B.[SiloDesc], ' (', B.[TitleDesc], ') ', B.[SkillSetDesc])
Samples:
select concat('john', ' (' + null + ')', ' adams') -- john adams
select concat('john', ' (test)', ' ' + null) -- john (test)
select concat('john', ' (the man)', ' adams') -- john (the man) adams
isnull(B.[SiloDesc], '')
+ ' (' + isnull(B.[TitleDesc], '') + ') '
+ isnull(B.[SkillSetDesc], '') as SkillSetDesc,
In table pics I have 3 different rows, where surname, name and middle name are stored.
In query I need to glue them to one string:
pics.e_family + ' ' + pics.e_name + ' ' + pics.e_sname AS fio
All works perfectly, but one entry don't have middle name at all (no mistake, its really so). And in fio I get NULL. Is there any possibility to modify code, or make additional check if one or more of the rows are null, replace it with space symbol or just show remain rows?
If you mean columns instead of rows, you can use COALESCE or ISNULL:
pics.e_family + ' ' + COALESCE(pics.e_name, '') + ' ' + pics.e_sname AS fio
I'm trying to get a row with the concatenation of a welders names.
This is what i've got:
SELECT jsd1.JuntaSoldaduraID,
REPLACE(RTRIM((SELECT s1.Nombre + ' ' + s1.ApPaterno + ' ' +
s1.ApMaterno + '' + CAST('' AS VARCHAR(MAX)) + ' '
FROM JuntaSoldaduraDetalle jsd
INNER JOIN Soldador s1 on s1.SoldadorID = jsd.SoldadorID
WHERE (jsd1.JuntaSoldaduraID = jsd.JuntaSoldaduraID)
and (jsd.TecnicaSoldadorID = 2)
FOR XML PATH (''))),' ',', ') AS NombreSoldador
FROM JuntaSoldaduraDetalle jsd1
INNER JOIN Soldador s
ON s.SoldadorID = jsd1.SoldadorID
GROUP BY jsd1.JuntaSoldaduraID
I'm able to get the information that i want but with a little problem.
What I want is "John Smith, David Rogers, Peter Simons" etc.. in other words, full names separated by commas.
But i'm receiving "John, smith, David, Rogers, Peter, Simons"..
Any help appreciated.
Thanks in advance.
Your REPLACE will replace all spaces with a comma. Instead, make the comma part of your query and use STUFF to remove the first occurrence of the comma. You might also want to incorporate the use of COALESCE in case any of the name fields are NULL.
SELECT jsd1.JuntaSoldaduraID,
STUFF((SELECT ', ' + COALESCE(s1.Nombre + ' ','')
+ COALESCE(s1.ApPaterno + ' ','')
+ COALESCE(s1.ApMaterno,'')
FROM JuntaSoldaduraDetalle jsd
INNER JOIN Soldador s1
on s1.SoldadorID = jsd.SoldadorID
WHERE jsd1.JuntaSoldaduraID = jsd.JuntaSoldaduraID
and jsd.TecnicaSoldadorID = 2
FOR XML PATH ('')),1,2,'') AS NombreSoldador
FROM JuntaSoldaduraDetalle jsd1
INNER JOIN Soldador s
ON s.SoldadorID = jsd1.SoldadorID
GROUP BY jsd1.JuntaSoldaduraID
You are replacing single spaces in the result with a comma and a space.
What is the result if you remove the REPLACE from the query?
