the old query works, the new on doesnt. the android logcat gives me error as:
Failure 1: no such column abcname. abcname is the value of a editview that im trying to get from a popup in android.
i know that the first query will insert those values in the fields, as they are given in single inverted commas. the same query, i typed in the adb shell, works. so i copied the query, and just removed the data corresponding to the field names, and inserted the variable names. on trying to run, i get the above said error.
OLD QUERY:
MapsActivity.myDB.execSQL("INSERT INTO "
+MapsActivity.TableName
+ " (name, user_comment, latitude, longitude) "
+ " VALUES ('tagName','tagComment','tagLatitude','tagLongitude');");
NEW QUERY:
MapsActivity.myDB.execSQL("INSERT INTO "
+MapsActivity.TableName
+ " (name, user_comment, latitude, longitude) "
+ " VALUES ("+tagName +",'tagComment','tagLatitude','tagLongitude');");
what is the problem?
If tagName has, e.g., the value "abc", your query will expand to ... VALUE (abc,'tagComment',.... It's missing the single quotes.
Building SQL like this give bad karma. Use SQLite's parameter-binding mechanism instead.
I recommend creating a simple active record db implementation. here is a great tutorial for a simple sqlite active record for android. This adds some extra time up front but saves you time while you develop.
wrap your double quotes with single quotes?
...('"+tagName +"',....

I have to remove the accents from the person's name, but I cannot apply the function in Talend while it works in SQL oracle.
this query works in my tDBInput component :
"SELECT '"+((String)globalMap.get("copyOfSORTIE.NOM"))+"' as nom_nom_compl,
'"+((String)globalMap.get("copyOfSORTIE.ENTETE"))+"' entete
FROM DUAL"
However, when I want to add the convert function, it doesn't work
this query does not work :
"SELECT '"+((String)globalMap.get(CONVERT("copyOfSORTIE.NOM",'US7ASCII')))+"' as nom_nom_compl,
'"+((String)globalMap.get("copyOfSORTIE.ENTETE"))+"' entete
FROM DUAL"
In my talend :
I am getting this error
What is the syntax for it to work?
Thank you!
Two things there :
I don't know the CONVERT method, but I can see that you are applying it to the key of your globalMap variable , and not the value (as if you wanted to convert "myKey" and not "myValue" which is attached to the key). Are you sure this is what you want to achieve ? if not, the syntax should be something similar to "SELECT CONVERT('"+((String)globalMap.get("copyOfSORTIE.NOM"))+"','US7ASCII') "
A useful java method implemented in talend is TalendString.removeAccents("") that you can apply directly on your talend variable, thus not using a SQL method.
I am a bit stumped with what happens here. I'm working on a challenge for an online programming course and the solution involves adding a second where statement to the sql query.
when I do this, however, python gives me a typeerror, saying "TypeError: 'NoneType' object is not subscriptable".
I'm pretty sure this is because the fetchone()[1] at the end requires a list or tuple to retrieve the ID. what I don't understand is why adding the second bit of the WHERE clause would change the type of the result.
I have checked the statement itself and it works when testing it on the database, and the first link_id statement in the code below works fine, it returns an int object but the second gives an error. It should return a similar int object.
link_id = self.cursor.execute(self.sql_select + " WHERE " + self.field + "=?", (value,)).fetchone()[1]
print("link_id type:", type(link_id))
link_id = self.cursor.execute(self.sql_select + " WHERE " + self.field + "=? AND albums.artist=?", (value, self.artist_id)).fetchone()[1]
print("link_id type:", type(link_id))
it was because self.artist_id was None. it reset when running this block of code again.
I am trying to create an insert statements that will allow the " ' " mark to be used as data, and having problems finding a reference to it. My current statement:
$sql = "INSERT INTO turnover(tail, discription, date) values ('$tail', '$discription', '$date')";
How ever when i put though this sample data i get:
INSERT INTO turnover(tail, discription, date) values ('173AB', 'No Dying MEL's tonight.', '05-14-2018')
If i remove the ' then it works fine. It seems i saw something a long time ago on it, but cannot find it.
Thanks in advance for any information that anyone can offer.
Best practice: Use prepared statements. Asuming you are using PHP: http://php.net/manual/en/pdo.prepared-statements.php
Alternatively you would apply some sort of escaping, like mysqli_real_escape_string().
Take care not to mix PDO and MySQLi functions, and do not in any case use mysql_*() functions.
INSERT INTO turnover(tail, discription, date) values ('173AB', 'No Dying MEL''s tonight.', '05-14-2018')
Trying to wrap my head around zoho creator, its not as simple as they make it out to be for building apps… I have an inventory database, and i have four fields that I call to fill a field called Inventory Number (Inv_Num1) –
First Name (First_Name)
Last Name (Last_Name)
Year (Year)
Number (Number)
I have a Custom Function script that I call through a Custom Action in the form report. What I am trying to do is upload a CSV file with 900 entries. Of course, not all of those have those values (first/last/number) so I need to bulk edit all of them. However when I do the bulk edit, the Inv_Num1 field is not updated with the new values. I use the custom action to populate the Inv_Num1 field with the values of the other 4 fields.
Heres is my script:
void onetime.UpdateInv()
{
for each Inventory_Record in Management
{
FN = Inventory_Record.First_Name.subString(0,1);
LN = Inventory_Record.Last_Name.subString(0,1);
YR = Inventory_Record.Year.subString(2,4);
NO = Inventory_Record.Number;
outputstr = FN + LN + YR + NO;
Inventory_Record.Inv_Num1 = outputstr;
}
}
I get this error back when I try to run this function
Error.
Error in executing UpdateInv workflow.
Error in executing For Each Record task.
Error in executing Set Variable task. Unable to update template variable FN.
Error evaluating STRING expression :
Even though there is a First Name for example, it still thinks there is none. This only happens on the fields I changed with Bulk Edit. If I do each one by hand, then the custom action works—but of course then the Inv_Num1 is already updated through my edit on success functions and makes the whole thing moot.
this may be one year late, you might have found the solution but just to highlight, the error u were facing was just due to the null value in first name.
you just have put a null check on each field and u r good to go.
you can generate the inv_number on the time of bulk uploading also by adding null check in the same code on and placing the code on Add> On Submt.( just the part inside the loop )
the Better option would be using a formula field, you just have to put this formula in that formula field and you'll get your inventory_number autogenerated , you can rename the formula_field to Inv Number or whaterver u want.
Since you are using substring directly in year Field, I am assuming the
year field as string.else you would have to user Year.tostring().substring(2,4) & instead of if(Year=="","",...) you have to put if(Year==null , null,...);
so here's the formula
if(First_Name=="","",First_Name.subString(0,1))+if(Last_Name =="","",Last_Name.subString(0,1)) + if(Year=="","",Year.subString(2,4)+Number
Let me know ur response if u implement this.
Without knowing the datatype its difficult to fix, but making the assumption that your Inventory_Record.number is a numeric data item you are adding a string to a number:
The "+" is used for string Concatenation - Joiner but it also adds two numbers together so think "a" + "b" = "ab" for strings but for numbers 1 + 2 = 3.
All good, but when you do "a" + 2 the system doesn't know whether to add or concatenate so gives an error.
I got a problem with this code:
string sql = "select distinct ruoli.c_tip_usr"
+ " from vneczx_ute_app_trn ruoli"
+ " join vnecyd_ent_prf ind"
+ " on ruoli.c_ent = ind.c_ent"
+ " where ruoli.c_app = :appCode"
+ " and ruoli.c_ute_mat = :matricola"
+ " and ind.t_des_ent = :indirizzo";
var ruoli = session.CreateSQLQuery(sql)
.SetString("appCode", Config.Configurator.Istance.ApplicationCode)
.SetString("matricola", user.Matricola)
.SetString("indirizzo", indirizzoCasella)
.List<string>();
This code is correctly executed, the query logged is correct, and the parameter passed correctly evaluated... but it doesn't return any result at all.
Copying the query from the debug console and executing it directly in an Oracle client application (SQL Developer), it gets 2 results (the results I expect to be right).
I found out that the problem is in the last parameter indirizzo, and should depend on the fact that it contains a special char # (indirizzo is an email address).
So I ended up using this solution:
string sql = "select distinct ruoli.c_tip_usr"
+ " from vneczx_ute_app_trn ruoli"
+ " join vnecyd_ent_prf ind"
+ " on ruoli.c_ent = ind.c_ent"
+ " where ruoli.c_app = :appCode"
+ " and ruoli.c_ute_mat = :matricola"
+ " and ind.t_des_ent = '" + indirizzoCasella + "'";
var ruoli = session.CreateSQLQuery(sql)
.SetString("appCode", Config.Configurator.Istance.ApplicationCode)
.SetString("matricola", user.Matricola)
.List<string>();
But it gives me thrills! Aren't the parameters in a query supposed to handle specifically this situation, and thus handle themselves situations with special char, and so on?
Why here a string concatenation works better that a parametric query?
Isn't there a way to force the NHibernate engine to escape some special char?
Update:
I found out how to solve this particular issue: usign the trim command on the field who raise the problem, the problem disappears.
So last line of my sql string now is:
+ " and trim(ind.t_des_ent) = :indirizzo";
I can't understand why it solves the problem thought. Not the field, nor the variable contains empty chars and copying th query on SQL Developer works in both way.
So we have some luck soving the problem, but we have no idea why now it works?
Any thoughts?
even I was facing the same issue, but your hint using TRIM for column saved my day. Since I was looking for a long time, but not able to figure it out.
Along with that, I was able solve my issue by doing the below changes as well:
We were using CHAR datatype some of the columns which used in the query where clause. This was causing the issue to fetch the data from NHibernate. We changed the data type of that column from CHAR to VARCHAR2 and even updated the data with actual size and removed the TRIM from Where clause, the TRICK WORKED!!!! :)
So, any one face this kind of issue, first check whether you are having any column with CHAR and then change to VARCHAR2.
But one more thing you have to remember is: if you are running your application from ASP.Net Development Server, close it and re-run your application. Since if the opening Asp.Net Development Server and if you make any changes to datatype that will NOT be refreshed in your oracle connection. So, better you close the ASP.Net Development server and then re run the application.
Hope my points will help somebody in future!!

You are not using parameters in a SQL query if you want SQL parameters use a SQL stored proc
