When i write "IN(1,2,4,5,6,7,8,9,10)" inside of the procedure, i get correct result but when i add the id variable in the "IN", the results are incorrect. I made a function on mysql but its still not working, what can i do?
Strings (broadly, variable values) don't interpolate in statements. vKatID IN (id) checks whether vKatID is equal to any of the values listed, which is only one: the value of id. You can create dynamic queries using PREPARE and EXECUTE to interpolate values:
set #query = CONCAT('SELECT COUNT(*) AS toplam
FROM videolar
WHERE vTarih = CURDATE() AND vKatID IN (', id, ') AND vDurum = 1;')
PREPARE bugun FROM #query;
EXECUTE bugun;
You could use FIND_IN_SET( ) rather than IN, for example:
SELECT COUNT(*) AS toplam
FROM videolar
WHERE vTarih = CURDATE()
AND FIND_IN_SET( vKatID, id ) > 0
AND vDurum = 1
Sets have limitations - they can't have more than 64 members for example.
Your id variables is a string (varchar) not an array (tuple in SQL) ie you are doing the this in (in java)
String id = "1,2,3,4,5,6,7"
you want
int[] ids = {1,2,3,4,5,6,7}
So in your code
set id = (1,2,3,4,5,6,7,8,9,10)
I cannot help you with the syntax for declaring id as I don't know. I would suggest to ensure the code is easily updated create a Table with just ids and then change your stored procedure to say
SELECT COUNT(*) AS toplam
FROM videolar
WHERE vTarih = CURDATE() AND vKatID IN (SELECT DISTINCT id FROM idtable) AND vDurum = 1;
Hope this helps.

I have a complex SQL query where I have a few cases that use END AS variableName. I then use variableName to do some logic and then create a new variable which I want in the output result. However when I run the query, all the END AS variableNames that I have used are also outputted in the results.
Is there a way that I can exclude these variables as I only want the final variable that uses these variableNames.
Thanks
EDIT, here is a query explaining my problem
SELECT DISTINCT
mt.src_id AS “SRC_ID”,
CASE
WHEN mt.cd = ‘TAN’ THEN
(
(
SELECT SUM(src_amt)
FROM source_table st
WHERE mt.id = st.id
AND st._cd = ‘TAN’
AND st.amt_cd = ‘ABL’)
)
END AS src_amt
FROM MAIN_TABLE mt
WHERE
mf.dt >= 2021-12-12
AND SRC_AMT > 10
I need SRC_AMT to be used as some sort of logic but when I run the query, it prints out in the output as it's own column. I want to ignore this variable
you can wrap the whole thing into a new select-statement:
select SRC_ID from ( <entire previous query here> )
I'm reading and executing sql queries from file and I need to inspect the result sets to count all the null values across all columns. Because the SQL is read from file, I don't know the column names and thus can't call the columns by name when trying to find the null values.
I think using CTE is the best way to do this, but how can I call the columns when I don't know what the column names are?
WITH query_results AS
(
<sql_read_from_file_here>
)
select count_if(<column_name> is not null) FROM query_results
If you are using Python to read the file of SQL statements, you can do something like this which uses pglast to parse the SQL query to get the columns for you:
import pglast
sql_read_from_file_here = "SELECT 1 foo, 1 bar"
ast = pglast.parse_sql(sql_read_from_file_here)
cols = ast[0]['RawStmt']['stmt']['SelectStmt']['targetList']
sum_stmt = "sum(iff({col} is null,1,0))"
sums = [sum_sql.format(col = col['ResTarget']['name']) for col in cols]
print(f"select {' + '.join(sums)} total_null_count from query_results")
# outputs: select sum(iff(foo is null,1,0)) + sum(iff(bar is null,1,0)) total_null_count from query_results
I am getting array from front end to perform filters according that inside the SQL query.
I want to apply a LIKE filter on the array. How to add an array inside LIKE function?
I am using Angular with Html as front end and Node as back end.
Array being passed in from the front end:
[ "Sports", "Life", "Relationship", ...]
SQL query is :
SELECT *
FROM Skills
WHERE Description LIKE ('%Sports%')
SELECT *
FROM Skills
WHERE Description LIKE ('%Life%')
SELECT *
FROM Skills
WHERE Description LIKE ('%Relationship%')
But I am getting an array from the front end - how to create a query for this?
In SQL Server 2017 you can use OPENJSON to consume the JSON string as-is:
SELECT *
FROM skills
WHERE EXISTS (
SELECT 1
FROM OPENJSON('["Sports", "Life", "Relationship"]', '$') AS j
WHERE skills.description LIKE '%' + j.value + '%'
)
Demo on db<>fiddle
As an example, for SQL Server 2016+ and STRING_SPLIT():
DECLARE #Str NVARCHAR(100) = N'mast;mode'
SELECT name FROM sys.databases sd
INNER JOIN STRING_SPLIT(#Str, N';') val ON sd.name LIKE N'%' + val.value + N'%'
-- returns:
name
------
master
model
Worth to mention that input data to be strictly controlled, since such way can lead to SQL Injection attack
As the alternative and more safer and simpler approach: SQL can be generated on an app side this way:
Select * from Skills
WHERE (
Description Like '%Sports%'
OR Description Like '%Life%'
OR Description Like '%Life%'
)
A simple map()-call on the words array will allow you to generate the corresponding queries, which you can then execute (with or without joining them first into a single string).
Demo:
var words = ["Sports", "Life", "Relationship"];
var template = "Select * From Skills Where Description Like ('%{0}%')";
var queries = words.map(word => template.replace('{0}', word));
var combinedQuery = queries.join("\r\n");
console.log(queries);
console.log(combinedQuery);
This is driving me crazy. I want to do simple comparison of a column and a variable but it just doesn't work. The QUERY 1 in following code returns me my value when i do a simple select, but i use the resulting variable in my 2nd query it just doesn't work..
It looks sooooo simple but I've been working on this for hours. The complete sql proc is
The big confusing thing is that if I replace v_bbg_symbol with some hard coded 'Value' (like 'FEDL01') it gives a correct answer for Query 2, but when I use the variable v_bbg_symbol it just doesn't work any more
Declare
v_bbg_symbol VARCHAR2(50);
V_OLD_INS_NAME Varchar2(50);
Begin
--QUERY 1
SELECT BBG_SYMBOL into v_bbg_symbol FROM quotes_external WHERE ID = 1;
--Gives output - 'FEDL01'
DBMS_OUTPUT.PUT_LINE('I got here:'||v_bbg_symbol||' is my value');
-QUERY 2
SELECT NAME INTO V_OLD_INS_NAME FROM INSTRUMENT
JOIN CURVE_INSTRUMENT ON
INSTRUMENT.INSTRUMENT_ID = CURVE_INSTRUMENT.INSTRUMENT_ID
JOIN GENERIC_INSTRUMENT ON
CURVE_INSTRUMENT.GENERIC_INSTRUMENT_ID = GENERIC_INSTRUMENT.GENERIC_INSTRUMENT_ID
WHERE CURVE_INSTRUMENT.CURVE_SNAPSHOT_ID =
(SELECT MAX(CURVE_INSTRUMENT.CURVE_SNAPSHOT_ID) FROM CURVE_INSTRUMENT)
AND GENERIC_INSTRUMENT.INSTRUMENT_NAME = v_bbg_symbol;
--ORACLE ERROR 'No Data Found'
DBMS_OUTPUT.PUT_LINE('I got here:'||V_OLD_INS_NAME||' is the new value');
END;
The first 'SELECT' gives me value which i select INTO a variable 'v_bbg_symbol', but when I use the same variable 'v_bbg_symbol' in my 2nd QUERY it pretends as if there is no value passed and does not return any result. If I give static value of 'v_bbg_symbol' i.e. ('FEDL01' in this case) in my 2nd QUERY, the results come as expected.
Please help..
Here is your query, with table aliases to facilitate following it:
SELECT NAME INTO V_OLD_INS_NAME
FROM INSTRUMENT i JOIN
CURVE_INSTRUMENT ci
ON i.INSTRUMENT_ID = ci.INSTRUMENT_ID JOIN
GENERIC_INSTRUMENT gi
ON ci.GENERIC_INSTRUMENT_ID = gi.GENERIC_INSTRUMENT_ID
WHERE ci.CURVE_SNAPSHOT_ID = (SELECT MAX(ci.CURVE_SNAPSHOT_ID) FROM CURVE_INSTRUMENT ci) and
gi.INSTRUMENT_NAME = v_bbg_symbol;
What this says is that the maximum ci.curve_snapshot_id is not for the instrument that is associated with v_bbg_symbol. I think you want a correlated subquery:
SELECT NAME INTO V_OLD_INS_NAME
FROM INSTRUMENT i JOIN
CURVE_INSTRUMENT ci
ON i.INSTRUMENT_ID = ci.INSTRUMENT_ID JOIN
GENERIC_INSTRUMENT gi
ON ci.GENERIC_INSTRUMENT_ID = gi.GENERIC_INSTRUMENT_ID
WHERE ci.CURVE_SNAPSHOT_ID = (SELECT MAX(ci2.CURVE_SNAPSHOT_ID)
FROM CURVE_INSTRUMENT ci2
WHERE ci2.instrument_id = i.instrument_id
) and
gi.INSTRUMENT_NAME = v_bbg_symbol;
I'm currently struggling on how to execute my query on a Table object in Zend and get a Rowset in return. Reason I need particularly THIS is because I'm modifying a code for existing project and I don't have much flexibility.
Query:
SELECT *
FROM `tblname` ud
WHERE ud.user_id = some_id
AND
(
(ud.reputation_level > 1)
OR
(
(SELECT COUNT( * )
FROM `tblname` t
WHERE t.user_id = ud.user_id
AND t.category_id <=> ud.category_id
AND t.city_id <=> ud.city_id
) = 1
)
)
Is there a way to describe this query using Select object?
Previous SQL solution was very simple and consisted of one WHERE clause:
$where = $this->getAdapter()->quoteInto("user_id = ?",$user_id);
return $this->fetchAll($where);
I need to produce same type of the result (so that it could be processed by existing code) but for more complicated query.
Things I've tried
$db = Zend_Db_Table::getDefaultAdapter();
return $db->query($sql)->fetchAll();
---------------- OR ----------------------
return $this->fetchAll($select);
---------------- OR ----------------------
return $this->_db->query($sql)->fetchAll();
But they either produce arrays instead of objects or fail with Cardinality violation message.
I would appreciate any help on how to handle SQL text queries in Zend.
$dbAdapter = Zend_Db_Table::getDefaultAdapter();
//change the fetch mode becouse you don't like the array
$dbAdapter->setFetchMode(Zend_Db::FETCH_OBJ);
$sql = "you're long sql here";
$result = $dbAdapter->fetchAll($sql);
Zend_Debug::dump($result);
exit;
For a list of all fetch modes go to Zend_Db_Adapter
To write you're query using Zend_Db_Select instead of manual string , look at Zend_Db_Slect
