I need help . Here's the code . I want to vote from the table to pull out all the names , and to introduce them across the chart .
I tried to use * but it does not work :)
$sql="SELECT * FROM glasanje where ime='*'
if you want to extract only the names (ime), you have to put it in the SELECT statement, try this way:
SELECT ime
FROM glasanje
SELECT * means that you want to see all the columns, SELECT ime just the column ime.
The WHERE clause is used to select a subset of rows, for example if you want just the people with name Filip, you can write WHERE ime ='Filip'
Anyway these are a basic SQL functionality, I think you should try to study it a bit.

i am working on a table that includes a filter function.
For the filter i use a form where i enter the parameters.
Those are added to a string which is my SQL query.
So far it works fine.
There is oine input field where multiple parameters canbe added.
The plan is to seperate them with ; .
For example 520;521;522
My plan was to use str_replace to convert this in to sql Code.
For example
$str = str_replace(";", "" OR ", "520;521;522");
Results in to:
SELECT * FROM MaschinenVorgangslisteMitHV WHERE (VorgangNr LIKE '%520%' or '%522%' or '%523%')
But some how this code does not show the expected results.
I only get results for '%520%'
How do i need to adjust this query in order to have the sql query working?
$str = str_replace(";", "" OR ", "520;521;522");
Results in to:
SELECT * FROM MaschinenVorgangslisteMitHV WHERE (VorgangNr LIKE '%520%' or '%522%' or '%523%')
In another input field i search for names.
Here the query looks like this...
SELECT * FROM MaschinenVorgangslisteMitHV WHERE (Bearbeiter LIKE '%Heine%' OR Bearbeiter LIKE '%Wolf%' OR Bearbeiter LIKE '%Maiwald%')
This works fine!
The multiple like should be written as,
SELECT *
FROM MaschinenVorgangslisteMitHV
WHERE VorgangNr REGEXP '520|522|523';
I believe you need to add VorgangNr LIKE after every OR.
I'm having issue with my study project for creating database in MySQL.
I've imported data using LOAD to my created table from a CSV file. Now when I'm executing select * from mytable everything show up perfectly, but when I execute select * from bi_jogging.routes as r where r.Creator_Email="jhenderson7c#bbb.org"
I get nothing.
The email is there, I've tried different syntax options but it seems to be something else, I suspect something with the varchar format, I really have nothing in mind.
For other tables it works fine and others not.
You can try using the query:
select * from bi_jogging.routes as r where r.Creator_Email like "%jhenderson7c#bbb.org%"
If like operator shows the result then there may be white spaces in the email, please double check..
For join try this:
select * from bi_jogging.routes as r join bi_jogging.buddies as b
on b.Email like '%r.Creator_Email%'
I think it should work. Again check with same code.
select * from bi_jogging.routes as r where r.Creator_Email='jhenderson7c#bbb.org'
if [select * from mytable] this works ,then try to copy the email from result and paste it in where clause.
There may be conflicts between quotes.
your table entry contains quotes???
check properly. i think you have quotes in your table entry,so when you try this,
select * from bi_jogging.routes as r where r.Creator_Email like "%jhenderson7c#bbb.org%"
'%' sign matches with any character and you will get the result.
Inside the tablejhenderson7c#bbb.org and "jhenderson7c#bbb.org" are completely different.
I found spaces in the mysql tables after few emails, so I guess that was it. burned 8 hours on this one, thank you all. I could not find the spaces at the end of the mail by looking at it, I had to hit backspace to see that only after two hits the last char is deleted
this helped me : UPDATE bi_jogging.results set Mail_Found = TRIM(Replace(Replace(Replace(Mail_Found,'\t',''),'\n',''),'\r',''));
I am having issues with my MySQL syntax. I would like to run a select query where either one of two options are true. However the following code does not work.
SELECT * FROM games WHERE genre="indie" OR title="indie"
I have been fooling around and look at other threads and have found out how to use OR to check the same column for multiple entries but not a way to check different columns for the same entries. When I do:
SELECT * FROM games WHERE genre="indie"
The query works fine. Any help would be greatly appreciated.
The only way I see this really would't work, is if you've mistyped the name of the column 'title' (if the second query you wrote works)
The assumptions about the case sensitivity are wrong, since the second query returns something, the first should return at least the same rows as the second one
In MySQL " " works just as ' ', so this assuption was wrong too.
If you post more information, it would be easier to help you
Maybe you ignoring the upper/lower case? Also use like
You can use this:
SELECT * FROM games WHERE (LOWER(genre) like 'indie') OR (LOWER(title) like 'indie')
I have a lot of tables in my data base all with same structure. I want to select from all tables without having to list them all like so:
SELECT name FROM table1,table2,table3,table4
And I tried but this doesn't work:
SELECT name FROM *
Is there a way to select all tables in a database without listing each table in the query?
i am working on a online file browser, each directory has its own table
It is very unuseful due to one reason: when you have about 200 files (this situation is real, yeah?) you have about 200 tables. And if there are about thousand files in each directory.. etc. In some time you will either have slow processing while selecting from your database either have to buy more server resources.
I think you should change your database structure: just begin from adding parent_folder_id column to your table, after this you can put all your rows (files and directories -- because directory is a file too -- here you can add type column to determine this) into the one table.
As far as I know there are no such wildcards to select from *all tables. I would recommend writing a view and then call that view instead (it will save you writing out the names every time) – VoodooChild
That means you should not have a lot of tables with same structure at all.
But just one table with a field to distinguish different kinds of data, whatever it is.
Then select all would be no problem.
I found a solution, but I would still like to know if there is a simpler way or a better solution.
But here's what I came up with:
$tables = mysql_query("show tables");
$string = '';
while ($table_data = mysql_fetch_row($tables)){
$string.=$table_data[0].',';
}
$ALL_TABLES = substr($string,0,strlen($string)-1);
$sql="SELECT name FROM $ALL_TABLES ";
Sounds like you want to UNION together each table, so you get the results as if they were one big table. You'll need to write out the query in full like
SELECT * FROM table1 UNION SELECT * FROM table2 UNION ... SELECT * FROM tableN
Copy & paste may be your friend here.
I'm curious as to why you have lots of different tables with the same structure?
You can generate SELECT by cursor like this code
and find all result step by step in sql server:
--Author: Ah.Ghasemi
Declare #Select sysname;
DECLARE A CURSOR
FOR Select 'select ' + '*' + ' from ' + name
from sys.tables
--Where name like 'tbl%'
Order by name
OPEN A
FETCH NEXT FROM A INTO #Select
While (##FETCH_STATUS <>-1)
Begin
exec sp_executesql #Select
FETCH NEXT FROM A INTO #Select;
End
close A
Deallocate A
Please let us know if the problem is not resolved.
I hope you for the best
The following doesn't work, but something like this is what I'm looking for.
select *
from Products
where Description like (#SearchedDescription + %)
SSRS uses the # operator in-front of a parameter to simulate an 'in', and I'm not finding a way to match up a string to a list of strings.
There are a few options on how to use a LIKE operator with a parameter.
OPTION 1
If you add the % to the parameter value, then you can customize how the LIKE filter will be processed. For instance, your query could be:
SELECT name
FROM master.dbo.sysobjects
WHERE name LIKE #ReportParameter1
For the data set to use the LIKE statement properly, then you could use a parameter value like sysa%. When I tested a sample report in SSRS 2008 using this code, I returned the following four tables:
sysallocunits
sysaudacts
sysasymkeys
sysaltfiles
OPTION 2
Another way to do this that doesn't require the user to add any '%' symbol is to generate a variable that has the code and exceute the variable.
DECLARE #DynamicSQL NVARCHAR(MAX)
SET #DynamicSQL =
'SELECT name, id, xtype
FROM dbo.sysobjects
WHERE name LIKE ''' + #ReportParameter1 + '%''
'
EXEC (#DynamicSQL)
This will give you finer controller over how the LIKE statement will be used. If you don't want users to inject any additional operators, then you can always add code to strip out non alpha-numeric characters before merging it into the final query.
OPTION 3
You can create a stored procedure that controls this functionality. I generally prefer to use stored procedures as data sources for SSRS and never allow dynamically generated SQL, but that's just a preference of mine. This helps with discoverability when performing dependency analysis checks and also allows you to ensure optimal query performance.
OPTION 4
Create a .NET code assembly that helps dynamically generate the SQL code. I think this is overkill and a poor choice at best, but it could work conceivably.
Have you tried to do:
select * from Products where Description like (#SearchedDescription + '%')
(Putting single quotes around the % sign?)
Dano, which version of SSRS are you using? If it's RS2000, the multi-parameter list is
not officially supported, but there is a workaround....
put like this:
select *
from tsStudent
where studentName like #SName+'%'
I know this is super old, but this came up in my search to solve the same problem, and I wound up using a solution not described here. I'm adding a new potential solution to help whomever else might follow.
As written, this solution only works in SQL Server 2016 and later, but can be adapted for older versions by writing a custom string_split UDF, and by using a subquery instead of a CTE.
First, map your #SearchedDescription into your Dataset as a single string using JOIN:
=JOIN(#SearchedDedscription, ",")
Then use STRING_SPLIT to map your "A,B,C,D" kind of string into a tabular structure.
;with
SearchTerms as (
select distinct
Value
from
string_split(#SearchedDescription, ',')
)
select distinct
*
from
Products
inner join SearchTerms on
Products.Description like SearchTerms.Value + '%'
If someone adds the same search term multiple times, this would duplicate rows in the result set. Similarly, a single product could match multiple search terms. I've added distinct to both the SearchTerms CTE and the main query to try to suppress this inappropriate row duplication.
If your query is more complex (including results from other joins) then this could become an increasingly big problem. Just be aware of it, it's the main drawback of this method.
