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 need some help with the query below - I am trying to pull information regarding price and multiply with the quantity & insert the sum into the table. So far I have,
update passenger_baggage
SET passenger_baggage.total_baggage_cost=passenger_baggage.passenger_baggage_quantity*baggage_type.baggage_type_cost
FROM passenger_baggage INNER JOIN baggage_type
ON passenger_baggage.passenger_baggage_id = baggage_type.baggage_type_id
WHERE passenger_id = "3";
and getting this error
#1064 - 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 'FROM passenger_baggage INNER JOIN baggage_type ON
passenger_baggage.passenge...' at line 3
Expecting the query to multiply the two values & insert the total.
There is no FROM clause in an UPDATE query.
Try with this modified query:
update passenger_baggage
INNER JOIN baggage_type
ON passenger_baggage.passenger_baggage_id = baggage_type.baggage_type_id
SET passenger_baggage.total_baggage_cost = passenger_baggage.passenger_baggage_quantity * baggage_type.baggage_type_cost
WHERE passenger_id = "3";
Try this:
UPDATE passenger_baggage, baggage_type
SET passenger_baggage.total_baggage_cost = passenger_baggage.passenger_baggage_quantity * baggage_type.baggage_type_cost
WHERE passenger_baggage.passenger_baggage_id = baggage_type.baggage_type_id AND passenger_id = "3";
Saw an example from the MySQL doc (https://dev.mysql.com/doc/refman/8.0/en/update.html)
Dim Def_Command_MySQL1 As MySql.Data.MySqlClient.MySqlCommand
Def_Command_MySQL1.Parameters.Clear()
Def_Command_MySQL1.CommandText = "SET #OutID = 10;"
or
Def_Command_MySQL1.CommandText = "UPDATE ID_Max1 SET IdMax = IdMax + 1 , #OutID = IdMax + 1 where TypeID>1"
Def_Command_MySQL1.Parameters.Add(New SqlParameter("#OutID", SqlDbType.Int)).Value = 41
Def_Command_MySQL1.Parameters("#OutID").Direction = ParameterDirection.Output
Def_Command_MySQL1.ExecuteNonQuery()
IDMax_Update = Def_Command_MySQL1.Parameters("#OutID").Value
Err.Description "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 '41 = 10' at line 1" String
or
Error = 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 '1=IdMax + 1 where TypeID>1' at line 1
First you set AllowUserVariables on True(Default is False in your connection string see https://dev.mysql.com/doc/connector-net/en/connector-net-6-10-connection-options.html
second get rid of the parameter code, because you replace mysql user defined variables #OutID with an actual value, which results in your error message.
With
SET #OutID = 10;"
You set in mysql a user defined variable #OutID to the numer 10.
But in general, following code add two parameters to a insert query
Def_Command_MySQL1.CommandText = "INSERT INTO myTable (myColumn1, myColumn2) VALUES (#C1, #C2)"
Def_Command_MySQL1.Parameters.AddWithValue("#C1", 1)
Def_Command_MySQL1.Parameters.AddWithValue("#C2", 2)
Def_Command_MySQL1.ExecuteNonQuery()
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);
Error

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
$produpd = "UPDATE tblnavpc SET tblnavpc.ChildName = tblnav.NavName " .
"FROM tblnav WHERE tblnavpc.CID = tblnav.NavID";
This is the error I get"
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 'FROM tblnav
WHERE tblnavpc.CID = tblnav.NavID' at
line 1
I know keys aren't named greatly but I just trying to fix this one problem, I didn't name the tables.
You don't have a FROM clause in an update:
UPDATE tblnavpc
INNER JOIN tblnav ON tblnavpc.CID = tblnav.NavID
SET tblnavpc.ChildName = tblnav.NavName
"From" cannot be used with update statements.
Should be
$produpd = "UPDATE tblnavpc SET tblnavpc.ChildName = tblnav.NavName " .
"WHERE tblnavpc.CID = tblnav.NavID";
