I'm working on a project that has a search engine. AS we know in MS ACCESS we could use "*" in Queries under Criteria field to retrieve all records.
In SQL Server I need the same technique. I have tried different LIKE with WHERE Clauses. But I still didn't get the exact result I want.
In this project I have 3 textboxes (Category, Item, Location). If the user leaves any of them empty. I want to retrieve all the records.
I need something like this:
string t1,t2,t3;
if(!String.IsNullOrEmpty(txtCategory.Text))
t1=txtCategory.Text;
else
t1="*";
if(!String.IsNullOrEmpty(txtItem.Text))
t2=txtItem.Text;
else
t2="*"
if(!String.IsNullOrEmpty(txtLoc.Text))
t2=txtLoc.Text;
else
t3="*";

-
// in a function i have this :
SELECT * FROM Table_Items WHERE Category='"+t1+"' AND Item='"+t2+"' AND Location='"+t3+"'"
in ms sql server you can use the same technique but instead of * you should use %.
for examples:
%: means any
a%: all strings that start with a
%z: all strings that end with z
SO, your code should look like something as below:
// codes here
t3="%";
WHERE ColumnName LIKE t3
or
Where ColumnName LIKE '%'
I hope that will help you.
Change your * to the %
... Where Category Like "'+t1+"' and Item Like '"+t2+"' ...

Is it possible to define an array in the vars section and use it inside the SQL syntax of a model?
Something like this
dbt_project.yml:
vars:
active_country_codes: ['it','ge']
model.sql
SELECT ...
FROM TABLE WHERE country_code IN ('{{ var("active_country_codes") }}')
I've tried with a single value, i.e:['it'], and works but if I add another it starts failing.
I am using the SQL Server Data connector.
The query that you are writing is correct. You just need to pass the variable as a string with a comma also as a string character.
vars:
active_country_codes: 'it'',''ge'
You can do something like this :
SELECT ...
FROM TABLE WHERE country_code IN ('{{ var("active_country_codes") }}')
And it will create query for you like this:
SELECT ...
FROM TABLE WHERE country_code IN ('it,'ge')
I have tested this and it's working fine. I'm using Bigquery Connection but it shouldn't matter as it's dbt generation.
My educated guess is that the result of {{ var("active_country_codes") }} is to insert a comma separated string. In that case, you'll need a string splitting function. You will have to roll your own if you haven't already, unless you have SQL Server 2016 or later. Then you can use string_split. Below is code using it. I use the exists approach as opposed to in due to performance.
select ...
from table t
where exists (
select 0
from string_split('{{ var("active_country_codes") }}', ',') ss
where t.country_code = ss.value
)
I would use:
vars:
var_name: "'one','two','three'"
where field_name in ({{ var("var_name") }})
Looks a little bit clearer than:
active_country_codes: 'it'',''ge'
So, I have Hibernate 5.3.1 in a project which connects to different enginees (MySql, Oracle, PostgreSQL and MS SQL), so I can't use native queries.
Let's say I have 3 records in a table, which all of them have the same datetime, but I need to group them only by date (not time). For example, 2019-12-04;
I execute this query:
SELECT
CONCAT(year(tx.date_), month(tx.date_), day(tx.date_)),
iss.code,
COUNT(tx.id)
FROM
tx_ tx
JOIN
issuer_ iss
ON
tx.id_issuer = iss.id
GROUP BY
CONCAT(year(tx.date_), month(tx.date_), day(tx.date_)), iss.code
But, when I test it connected to SQL SERVER 2017, instead of return 20191204, it's returning 2035. In Oracle and MySQL is working fine.
Anyone has any idea why is this happen? I've tried different ways, like use + instead of CONCAT but the result is the same.
I've also tried to extract them for separate (without concat), and they have been returning correct. The problem is, I need to group them by the complete date.
And just for the record, the field is declared as datetime2 in DDBB
How about simply adding them, instead of using CONCAT.
(year(tx.date_)*10000 + month(tx.date_)*100 + day(tx.date_)*1) AS datenum
Thus, try this:
SELECT
CAST((year(tx.date_)*10000 + month(tx.date_)*100 + day(tx.date_)*1) AS string) AS datenum,
iss.code
FROM tx_ tx
JOIN issuer_ iss
ON tx.id_issuer = iss.id
GROUP BY year(tx.date_), month(tx.date_), day(tx.date_), iss.code
Thanks for the hint Gert Arnold gave me. I just didn't realize that the query was adding like if they were numbers in MSSQL.
Finally, I manage to make it work in the 4 RDBMS casting to string first
SELECT
CONCAT(CAST(year(tx.date_) AS string), CAST(month(tx.date_) AS string), CAST(day(tx.date_) AS string)),
iss.code
FROM
tx_ tx
JOIN
issuer_ iss
ON
tx.id_issuer = iss.id
GROUP BY
CONCAT(year(tx.date_), month(tx.date_), day(tx.date_)), iss.code
I tried also casting to TEXT, but it throws exception in MySQL
Why use concat() to begin with?
Assuming Hibernate takes care of converting the non-standard year(), month() and day() functions, then the following should work on any DBMS
SELECT year(tx.date_), month(tx.date_), day(tx.date_), iss.code
FROM tx_ tx
JOIN issuer_ iss ON tx.id_issuer = iss.id
GROUP BY year(tx.date_), month(tx.date_), day(tx.date_), iss.code
İ have a problem with contains function, when i search with like '%ZAM%' operator, it finds all word that contains ZAM like ZAMANLAMA AZAMI ZAM and etc.. but when I use fts index contains function, it just find ZAM ZAMANLAMA but it doesnt find AZAMI or 123ZAM789. I have also tried CONTAINS (YourColumn, ' "ZAM" ' ) but it doesn't work. Please help me , fts is very fast but it could not find all contains like '%%' operator what should I do ?
You can use "*" before in contain syntax same as like operator . but you need to use double quote before and after the search string.
Try this query once.
SELECT *
FROM YourTable
WHERE CONTAINS(YourColumn,'"*ZAM*"');
(OR)
select * from YourTable where YourColumn like '%ZAM%'
I'm trying to form a SQL query, using SQL Server 2014 without creating a function. I do not have permissions on the database to create functions so I have to do it with a query only.
I have a column named Test with the example value of:
Accounting -> Add Missing functionality in Payable -> Saving a blank Missing row
I want my query to return the information (of varying length) between the two arrows (->). I have tried the right, left, substring, charindex and patindex functions and various combinations of each.
Basically the query needs to be SUBSTRING(Test, CHARINDEX(' -> ', TEST) +3, <some length here>)
The length is the part I'm having a hard time figuring out. I need the full length minus the first part before and including the first -> which evaluates to:
Add Missing functionality in Payable -> Saving a blank Missing row
From that result, I need to remove everything after and including the ->, which would then leave me with:
Add Missing functionality in Payable
At the end of the day, I want to split this one column up into 3 like so:
Domain | Feature | Test
------------------------------------------------------------------------------
Accounting | Add Missing functionality in Payable | Saving a blank Missing row
Can anyone show me how to do this query, without having to write a function? Any suggestions would be greatly appreciated as I have been working on this one portion of the query for the better part of 4 hours now. Thank you in advance for your help. Have a great day!!
I tried the following query and it is woking fine for me:
DECLARE #X as varchar(1000)
SET #X = 'Accounting -> Add Missing functionality in Payable -> Saving a blank Missing row'
SELECT SUBSTRING(#X,1,CHARINDEX('->',#X) - 1) AS Domain,
SUBSTRING(#X,CHARINDEX('->',#X) + 2,LEN(SUBSTRING(#X,CHARINDEX('->',#X) + 2,LEN(#X))) - LEN(SUBSTRING(#X,LEN(#X) - CHARINDEX('>-',REVERSE(#X)) ,LEN(#X)))) AS Feature,
SUBSTRING(#X,LEN(#X) - CHARINDEX('>-',REVERSE(#X)) + 2 ,LEN(#X)) AS Test
You have to use this query:
SELECT SUBSTRING([Test],1,CHARINDEX('->',[Test]) - 1) AS Domain,
SUBSTRING([Test],CHARINDEX('->',[Test]) + 2,LEN(SUBSTRING([Test],CHARINDEX('->',[Test]) + 2,LEN([Test]))) - LEN(SUBSTRING([Test],LEN([Test]) - CHARINDEX('>-',REVERSE([Test])) ,LEN([Test])))) AS Feature,
SUBSTRING([Test],LEN([Test]) - CHARINDEX('>-',REVERSE([Test])) + 2 ,LEN([Test])) AS Test
FROM MyTable --Replace MyTable with your table name
Is there a (supposedly) simple way to get an exact match when using the replace function in SQL Server 2012? (I'm open to other searching possibilities as well, of course)
For example, I'm using the following code to grab all the objects in a DB containing 'texter' in it at some point:
select OBJECT_NAME(object_id) name,
OBJECT_DEFINITION(object_id) code,
type
into #tester
from sys.objects
where OBJECT_DEFINITION(object_id) LIKE '%texter%'
This doesn't seem to differentiate between .texter, #texter or stupidtexter.
and so if I use:
update #tester
set code = REPLACE(code, 'texter', 'bluenose')
where code LIKE '%texter%'
It's going to replace any variant of 'texter' with 'bluenose'
Let's assume I only want to replace the ' texter' and '.texter' versions of this and nothing else (noting that within each object it is possible that #texter or stupidtexter may also be present in the object code).
Is there a way I can differentiate between the variants of 'texter', #texter and stupidtexter?
Thanks
The solution was:
replace(REPLACE(code, '.texter', 'bluenose'), ' texter', 'bluenose')
Thanks to Sean Lange for the answer!
