I am trying to use variable in a SQL query but failed. What it the way to do this ?
var SicilNumvber = SessionCurrentUser.EMPNO;
string query = "select * from crm_visible_v where ownerid in (select sicilno from personel.pkim_kutlama#netdb_1.europe.nortel.com where cikis_tarihi is null start with sicilno = :SicilNumvber connect by prior sicilno = amir)";
Regards
Please concatenate the fixed string with the variable part as I have done below
string query := 'select * from crm_visible_v where ownerid in (select sicilno
from personel.pkim_kutlama#netdb_1.europe.nortel.com where cikis_tarihi is null
start with sicilno ='||SicilNumvber||' connect by prior sicilno = ''''amir'';
The success query is as below:
Thanks for your helps;
string query = "select * from crm_visible_v where ownerid in (select sicilno from personel.pkim_kutlama#netdb_1.europe.nortel.com where cikis_tarihi is null start with sicilno ='"+SicilNumvber+"' connect by prior sicilno = amir)";

SQL table:
SELECT id,
account_name,
parent_id
FROM
(SELECT id,
account_name,
parent_id,
CASE
WHEN id = 1 THEN #idlist := CONCAT(id)
WHEN FIND_IN_SET(parent_id, #idlist) THEN #idlist := CONCAT(#idlist, ',', id)
END AS checkId
FROM chart_of_account
ORDER BY id ASC) AS T
WHERE checkId IS NOT NULL
When I run this query in MySQL it works fine and the result is fetched perfectly, but when I run it in Laravel like this:
$accountId = DB::select('SELECT id,account_name,parent_id FROM
(SELECT id,account_name,parent_id,
CASE WHEN id = '.$account_id.' THEN #idlist := CONCAT(id)
WHEN FIND_IN_SET(parent_id,#idlist) THEN #idlist := CONCAT(#idlist,', ',id)
END as checkId
FROM chart_of_account
ORDER BY id ASC) as T
WHERE checkId IS NOT NULL');
it gives an error.
Argument 1 passed to Illuminate\\Database\\Connection::prepareBindings() must be of the type array, string given,
Try this:
$query = 'YOUR_QUERY_THE_BIG_ONE:)';
$result = DB::select($query,[]);
dd($result);
Optionally, you can use ? sign in your query wherever you are using user inputs to prevent mySQL injection issue and then provide their value in second parameter array of select function. One example would be:
$inputUserEmail = $request->input('email');
$query = 'SELECT * FROM users WHERE email=?';
$result = DB::select($query,[$inputUserEmail]);
dd($result);
I hope it gives you an idea
I have a query in a variable and I want to run it :
$sql = "select id,
title,
parent_id
from (select * from categories
order by parent_cat_id, id) base,
(select #pv := '$category_id') tmp
where find_in_set(parent_cat_id, #pv) > 0
and #pv := concat(#pv, ',', id)";
How can run it as a query ?
I was able to run the query using the DB::select function:
$categories = DB::select($sql);
dd($categories);
I am not able to use the with clause in oracle adodb connection. I have tried both wrapping the qry is a select * from (myquery) and adding a , before my with clause. All create errors.
Here is the query
`WITH TEMPa AS (select _nbr, sum(ending) as Cost from t1 group by _nbr),
TEMPB AS (select _nbr, cost,entity
from t2
where end_tms is null and sale_date is null and entity = 110)
SELECT
TEMPA._nbr
,TEMPA.cost
,TEMPb._nbr
,TEMPB._cost
,tempb.entity
,(tempb._cost - tempa.cost) as Difference
FROM TEMPA, TEMPB
WHERE TEMPA._nbr = TEMPB._nbr(+)
and tempa.cost <> tempb.cost`
Any help would be awesome!
In oracle we using select * from table_name where column_name=&value in similar way how to use ampersand in JDBC?
stmt = conn.createStatement();
String sql;
sql="select emp_name from employees"+" where emp_no=?";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()){
String emp_name=rs.getString("emp_name");
System.out.println(emp_name);
}
i wrote the above code but it is not working(showing error)
Did you read the article I provided the link to?
You use the question mark ? to point out places in your query where you want to specify a parameter, and you have to use PreparedStatement. I can't test it, but it should be something like this:
// some code to obtain the Connection object
PreparedStatement stmt = null;
String yourQuery = " SELECT emp_name FROM employees WHERE emp_no = ? ";
try {
stmt = conn.prepareStatement(yourQuery);
stmt.setLong(1, 252);
ResultSet rs = stmt.executeQuery();
while(rs.next()) {
String emp_name = rs.getString("emp_name");
System.out.println(emp_name);
}
} finally {
// close the stmt etc.
}
I'd suggest using a PreparedStatement - from memory it's something like
Connection conn = getConnection();
PreparedStatement pstmnt = conn.prepareStatement("Select * from employees where emp_no =?");
pstmnt.setLong(1,emp_no);
ResultSet rs = pstmnt.executeQuery();
but the link that #Przemyslaw Kruglej high light above will almost certainly have a good example ( I haven;t read it though ... )
If I run the SQL in Fig. 1 below, it may return something like this:
Select fname, lname from name_tbl where nam_key = :key
Without using some fancy DBA trace utility, how can I query an Oracle system table to find the value of the bind variable “:key”?
Figure 1. - List the current running sql statement.
select sid, username, sql_text
from v$session,
v$sqltext
where sql_address = address
and sql_hash_value = hash_value
order by sid, piece;
select name, value_string
from v$sql_bind_capture
where sql_id = your_query_id
Upd. or, of course:
select sql_id, value_string
from v$sql_bind_capture
where name = ':key'
