I am using MySQL with ASP.NET/VB. In a table I use GUID instead of int identifiers. All goes as planned until I try to update a specific row, where I get a syntax error in the statement below:
Dim q As String = "UPDATE documents SET date_document = #date_document, document_type = #document_type, sender = #sender, receiver = #receiver, description = #description, document_number = #document_number, pages = #pages, handled_date = current_timestamp, handled_user_id = #handled_user_id, error_code = #error_code) WHERE id = #id"
My GUID parameter:
.Parameters.Add("#id", MySqlDbType.Guid, 16).Value = myguid
And the error:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') WHERE id = '8873442f-2f0b-4372-ac08-8388220c6eca'' at line 1
Any ideas on what's going on?
You're chasing down the wrong issue. What character does your error syntax begin with? It starts off as ') Where id = ...
You're assuming it's the id. It's not. That works fine. The first character is a closing parenthesis. That's the clue. There is no opening parenthesis. Remove the ) because you don't need it with an update statement.

I tried running this sql
UPDATE table
SET read = 1
WHERE col1_id = 2
AND col3_id = 1;
and it return an error (error in your sql syntax)
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'read = 1 WHERE team_notification_id = 2 AND listener_id = 1' at line 1
But when I used thesame WHERE and AND :), in a SELECT statement no error was returned.
SELECT *
FROM read
WHERE col1_id = 2
AND col3_id = 1
please what did I do wrong, I am no seeing it.
After keyword UPDATE there should be a table name. If your table has actually name table (that's a bit strange) you should escape it to let MySQL know it's not a keyword "table" but actual table name.
The same thing is about read.
Both table and read are MySQL keywords (the full list is here http://dev.mysql.com/doc/refman/5.7/en/keywords.html) so if it's your actual table and column names then you should escape it.
Better to escape all table and column names to prevent issues like that.
Escaping in MySQL is done with backtick symbol ` so your query will looks like:
UPDATE `table`
SET `read` = 1
WHERE `col1_id` = 2
AND `col3_id` = 1;
UPDATE tablename
SET `field_name` = 1
WHERE col1_id = 2
AND col3_id = 1;
UPDATE table
SET [read] = 1
WHERE col1_id = 2
AND col3_id = 1;
I keep getting this syntax error in my MySQL code within a PHP file. I'm simply trying to increment/add to the value already in the table with this time variable. If anyone could help me out I'd greatly appreciate it.
PHP:
$sql = "UPDATE Aircraft
SET MaintenanceFlightTime = (MaintenanceFlightTime + $MaintenanceDuration),
WHERE AircraftID = $AircraftID";
Error:
UPDATE Aircraft SET MaintenanceFlightTime = (MaintenanceFlightTime + 00:10:00), WHERE AircraftID = 8
You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ':10:00), WHERE AircraftID = 8' at line 2
You cannot just add a string like '01:01:01' to a time column but you can use ADDTIME()
$MaintenanceDuration = '00:10:00';
$sql = "UPDATE Aircraft
SET MaintenanceFlightTime = ADDTIME(MaintenanceFlightTime, '$MaintenanceDuration')
WHERE AircraftID = $AircraftID";
I'm using MySqlCommand for perform query insert in my vb.net application, now I've this query:
UPDATE primo_appointments SET
book_datetime = #parameter1,
start_datetime = #parameter2,
end_datetime = #parameter3,
notes = #parameter4,
hash = #parameter5,
is_unavailable = #parameter6
WHERE hash = xqA5jdsFBLPTrvy5kKHfgXBZdv9Hs2Ld
AND lastUpdated = 12-01-2016 15:53:47.3978486
when I do: .ExecuteNonQuery() this error appear:
you have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '15:53:47.3978486' at line 1.
What is wrong?
Your lastUpdated and hash is not enclosed in single quotes which is the cause of your error.
The fix for this is not to enclose it in quotes, but to use a parameter for these values as well as the others:
UPDATE primo_appointments SET
book_datetime = #parameter1,
start_datetime = #parameter2,
end_datetime = #parameter3,
notes = #parameter4,
hash = #parameter5,
is_unavailable = #parameter6
WHERE hash = #oldHashString
AND lastUpdated = #lastUpdatedDate
When you use a parameterised list, you don't have to remember whether a field needs to be surrounded by quotes or not - this is handled for you. It also protects you from SQL injection attacks.
your varchar should between 2 ', you query should be:
UPDATE primo_appointments SET book_datetime = #parameter1,
start_datetime = #parameter2, end_datetime = #parameter3,
notes = #parameter4, hash = #parameter5, is_unavailable = #parameter6
WHERE hash = 'xqA5jdsFBLPTrvy5kKHfgXBZdv9Hs2Ld'
AND lastUpdated = '12-01-2016 15:53:47.3978486'
here's the generated query:
UPDATE namelist
SET 'submitterName' = 'Jim'
,'actorName' = 'dingle'
,'setYear' = '1103'
,'country' = 'tanata'
,'blink' = 'on'
,'crush' = 'on'
,'initialize' = 'on'
,'entered' = 'on'
,'stuck' = 'on'
,'catapult' = 'on'
,'ruck' = 'on'
WHERE id = 31
it generates this (less than helpful) error:
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near (query snippet) at line 1
for the life of me, i can't spot where the problem is. yes, column names match, yes
TIA for helping out.
WR!
You have used single quotes before and after columns in the query, replace those single quotes with backquotes.
So the query like
UPDATE namelist
SET `submitterName`='Jim',
`actorName`='dingle',
`setYear`='1103',
`country`='tanata',
`blink`='on',
`crush`='on',
`initialize`='on',
`entered`='on',
`stuck`='on',
`catapult`='on',
`ruck`='on'
WHERE id=31;
user ` instead of '
like this
UPDATE namelist SET `submitterName`='Jim',`actorName`='dingle',`setYear`='1103',`country`='tanata',`blink`='on',`crush`='on',`initialize`='on',`entered`='on',`stuck`='on',`catapult`='on',`ruck`='on' WHERE id=31
i have a form and onClick listener i want to update some data on my database exception says that i have a syntax error but when i execute query at mysql console it works here is my code all variables are checked
String temp = itemList.getModel().getElementAt(itemList.getSelectedIndex()).toString();
PreparedStatement pt = supplies.con.prepareStatement("update prods set pquant = pquant + ? where pname = ?");
pt.setInt(1, Integer.parseInt(empsalary.getText()));
pt.setString(2, temp);
supplies.pst.executeQuery(temp);

As the compiler mentioned, there is indeed a Syntax error in your SQL query. Try:
String temp = itemList.getModel().getElementAt(itemList.getSelectedIndex()).toString();
PreparedStatement pt = supplies.con.prepareStatement("update prods set pquant = #0 + 21" + "'variableForPquant'" "where pname = #1" + "'variableForPname'");
pt.setInt(1, Integer.parseInt(empsalary.getText()));
pt.setString(2, temp);
supplies.pst.executeQuery(temp);
You need to use quotes when you are using variables in your SQL query. I believe it is either
"'variableName'" or '"variableName'"
I found my error i declare a variable pt and i execute the query from the statement that is empty pst i change to pt.executeUpdate(); and its ok now
