I want to search number of strings in the Database (type: MYSQL) and I did this:
SELECT *
FROM `rooms`
WHERE `dates` LIKE '%09/08/10%' OR '%08/08/10%'
Why doesnt it work? when I removed the part of OR '%08/08/10%' it was working well, I think I use it not good.
How should I do it?
SELECT ...
FROM rooms
WHERE dates LIKE '%09/08/10%'
Or dates LIKE '%08/08/10%'
Try like this:
SELECT *
FROM rooms
WHERE
dates LIKE '%09/08/10%'
OR
dates LIKE '%08/08/10%'

I have a simple select query on a table, but with different values in LIKE operator. Query is as follows:
SELECT *
FROM BatchServices.dbo.TaskLog
WHERE EntryTime BETWEEN '20190407' AND '20190408' AND
TaskGroup LIKE '%CSR%' AND
(LogText LIKE '%error%' OR LogText LIKE '%fail%')
This above query is fine and returning me the expected results but I don't want to have multiple LIKE in a query, so I have already tried something like
SELECT *
from BatchServices.dbo.TaskLog
WHERE taskgroup = 'csr' AND
LogText IN ( '%error%','%fail%') AND
EntryTime>'2019-04-07'
ORDER BY EntryTime ASC
This query is not giving me any results.
I am expecting a query which looks smarter than the one I have which returns result. Any help?
use like operator with OR condition
SELECT * from BatchServices.dbo.TaskLog WHERE taskgroup ='csr' AND
(LogText like '%error%' or LogText like '%fail%')
AND EntryTime>'2019-04-07'
ORDER BY EntryTime ASC
The LIKE operators are not the problem. It's the leading wild cards. Unless you cant get rid of those, your optimization options are going to be limited to making sure you have a covering index on EntryTime... That and replacing the "*" with the specific columns you need.
I am in the processing of preparing for migration to a new database system for a stock based retail store. In the current database products which have been deactivated have a leading * added to the record.
The owners do not want to bring deactivated products into the new system so this leading * is my only reference point to work from.
I need to create a SELECT query that will exclude products that have a leading * but so for to no avail.
I have tried the below
SELECT prdcod
FROM prdtbl
WHERE prodcod<>'*%';
The first 10 results returned are:
71A022
051116
070505PRO
*031620
458508
501315
*070247PE
370002
070278STU
*CO20302
I suspect I may not be able to use the * as an excluding factor
Any thoughts would be appreceated
This can be done in so many ways..
Using NOT LIKE
SELECT prdcod
FROM prdtbl
WHERE prodcod NOT LIKE '*%'
Using LEFT/SUBSTRING
SELECT prdcod
FROM prdtbl
WHERE LEFT(prodcod,1) <> '*' -- SUBSTRING(prodcod from 1 for 1) <> '*'
Note : Not Like is preferred approach if you have a Index on prodcod column
try this
SELECT prdcod
FROM prdtbl
WHERE prodcod not like '*%';
SELECT prdcod
FROM prdtbl
WHERE prodcod NOT LIKE '*%';
instead of using "<>" operator, use "not like":
Select prdcod
From prdtbl
Where prodcod not like '*%';
I'm currently making a call to an SQL database that counts all entries where the cell starts with NOI, but ends with anything else.
I thought using the below would work, but it doesn't seem to, anyone have any ideas? I know the % sign is the wildcard for foxpro, I don't know if this is the same in SQL
SELECT COUNT * FROM DIARY WHERE PTNOTE = 'NOI%'
You have to use LIKE if you want to use the wildcard characters:
SELECT COUNT(*) FROM DIARY WHERE PTNOTE LIKE 'NOI%'
(also added the parantheses around *)
You are missing parentheses:
SELECT COUNT(*)
FROM DIARY
WHERE PTNOTE = 'NOI%';
It is not the case even in Foxpro. You should use parentheses and "like":
SELECT COUNT(*) FROM DIARY WHERE PTNOTE like 'NOI%'
Welcome!
I am currently working on some C# and I encountered a rather silly issue. I need to fill ListBox with some data from database obviously. Problem is varchar filtering. I need to filter codes and display only the right ones.
Example of codes are: RRTT, RRTR, RT12, RQ00, R100, R200, R355, TY44, GG77 etc. Four digit codes.
I managed to filter only R-codes with simple select * from table1 where code_field like 'R%' but I get both R000 and RQ10 and I need to get R ones followed by numbers only.
So from example:
RRTT, RRTR, RT12, RQ00, R100, R200, R355
Only:
R100, R200, R355
Any ideas what should I add to the like 'R%'?
In SQL Server, you can make use of wildcards. Here is one approach:
where rcode like 'R___' and -- make sure code has four characters
rcode not like 'R%[^0-9]%' -- and nothing after the first one is not a number
Or:
where rcode like 'R[0-9][0-9][0-9]'
In other databases, you would normally do this using regular expressions rather than extensions to like.
here solution using like
SELECT *
FROM (
VALUES ( 'R123'),
( 'R12T' ),
( 'RT12' )
) AS t(test)
where test like 'R[0-9][0-9][0-9]'
like 'S[0-9%]'
Friend came up with the solution, thanks anyway
This is my first stakoverflow question, although I've lurked for quite a while. I'm writing a webapp in PHP/SQLite, and I'm trying to find a column name along with the following SQL query:
SELECT lexemeid FROM lexeme, sense WHERE lexeme.lexemeid =
sense.senselexemeid AND (lexeme.lexeme LIKE '%apani%' OR lexeme.variant
LIKE '%apani%' OR lexeme.affixedform LIKE '%apani%' OR sense.example
LIKE '%apani%');
Basically, I'm offering a full text lookup for a few different fields. The query above works, but I'd like to get the name of the column where my wildcard matches for each result as well. Basically I want something like the above query with the SELECT looking more like:
SELECT lexemeid, COLUMN NAME FROM...
I'd also welcome any ideas for making my SQL Query look/perform better (maybe using LIKE and IN??). I'm basically trying to join lexeme.lexemeid and sense.senselexemeid and do a wildcard lookup on a text string (in this case, "apani").
Thanks!
Assuming you only have a match in one of the columns, you could use a CASE statement.
SELECT lexemeid,
CASE WHEN lexeme.lexeme LIKE '%apani%' THEN 'lexeme'
WHEN lexeme.variant LIKE '%apani%' THEN 'variant'
...
WHEN sense.example LIKE '%apani%' THEN 'example'
END AS ColumnName
FROM ...
