Using mssql(6.3.1) and node(14.15.1).
Query works when I use the template literal as shown in the documentation.
This was my query within template literal and it works. (DB names aren't variables here)
await sql.query`
INSERT
INTO
DB.DB.notes (updated_date,
updated_user,
note_description,
work_order_id,
created_date ,
created_user)
values(
${normalizedDate},
${username} ,
${note_description},
${wo_id},
${normalizedDate} ,
${username} )
`;
But when I try to replace the DB with variables let's say ${DB}, it is throwing error.
First it was saying
RequestError: Incorrect syntax near "."
and after that I got
RequestError: Incorrect syntax near "17" (it started from 14 and it's incremented to 17)
This is the documentation, and I have tried a ConnectionPool class, .query('/**query**/'), but none worked for me.
Please suggest what is wrong here.
The syntax you're using in your query generates a parameterised query.
It is not possible to paramaterise "identifiers" in queries. See Can I parameterize the table name in a prepared statement?

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 using BigQuery, Standard SQL, and I want to dynamically change parts of the FROM clause, such as the project id. I have been looking for a solution for this the last 3 years - the problem has been that parameters cannot be used as inputs in the FROM clause. The benefit would be to create a stored procedure, where the project id can be passed in as an argument and can query the appropriate project. The projects would have the same datasets and table names - this would be our way of building a Master query for easy development and implementation. Instead of changing 15 clients' views, we can change the Stored Procedure once and it will push out the changes to all clients' views. However, I have always gotten hung up on dynamically changing the FROM clause!
For example:
DECLARE ProjectId STRING DEFAULT 'test_project';
SELECT col_1 FROM `#ProjectId.Dataset.Table`;
would always error out due to parameters not being able to be used in the FROM clause. However, I saw a related post on using dynamic SQL to overcome this obstacle. I've been looking into the EXECUTE IMMEDIATE function within BigQuery, as this is what has been cited to be a solution. From that post I attempted to implement in several ways:
Attempt #1:
DECLARE ProjectId STRING DEFAULT 'test_project';
EXECUTE IMMEDIATE CONCAT(
"SELECT * FROM ", #ProjectId, ".DataSet.`Table` " )
^ This gives an error "Query error: Undeclared query parameters at [2:19]"
Attempt #2:
EXECUTE IMMEDIATE CONCAT(
"SELECT * FROM ", #ProjectId, ".DataSet.`Table` " )
USING 'my-project' as ProjectId, 'my-dataset' as DataSet;
^ which gives the error "Query error: Undeclared query parameters at [1:19]"
Third and final attempt was to try declaring the parameter within the EXECUTE IMMEDIATE:
EXECUTE IMMEDIATE CONCAT(
"DECLARE ProjectId STRING DEFAULT 'test_project'; ",
"SELECT * FROM ", #ProjectId, ".DataSet.`Table` " )
USING 'my-project' as ProjectId, 'my-dataset' as DataSet;
^ which, you guessed it, results in the same error "Query error: Undeclared query parameters at [1:19]"
I am reaching out to see if anybody has had success with this? I see the value in the Dynamic SQL statements, and have read the documentation and some examples, but it still doesn't seem to work when trying to dynamically change the FROM clause. Any help is much appreciated, willing to try whatever is thrown out - excited to learn what can be done!
Just remove #:
DECLARE ProjectId STRING DEFAULT 'test_project';
EXECUTE IMMEDIATE CONCAT(
"SELECT * FROM ", ProjectId, ".DataSet.`Table` " )
I am trying to insert into my database, and the only problem I can find is the sql not being correct somehow. I tried searching up the errors, but they are confusing at to what they are.
$pdo = new PDO("mysql:host=$dbhost;dbname=$dbvideos;", $dbusername, $dbpassword);
$sql = "INSERT INTO Video ('Channel ID', 'Name', 'VideoDescription', 'VideoLocation') VALUES (:chanID, :vidName, :vDesc, :vLoc)";
$stmt = $pdo->prepare($sql);
$stmt->execute(array(":chanID"=>$_POST['selectedChannel'], ":vidName"=>$_POST['videoName'], ":vDesc"=>$_POST['viddesc'], ":vLoc"=> $VideoLocation));
print_r($stmt->errorInfo());
With error output:
Array ( [0] => 42000 [1] => 1064 [2] => 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 'ID, Name, VideoDescription,VideoLocation) VALUES ('1', 'Testing Video', 'This is' at line 1 )
I pre-checked the variables (types match database, and they exist and with validation on previous page). The connection works fine. So SQL is the only error I can find.
I understand having no space in names- that one slipped my mind (I am usually on top of that, even when saving files). Some how removing the space and removing ' quotes made it work. (I originally used ' quoted because I saw some people use it so I though it would fix the problem).
Thank You Ryan Vincent.
This question already has an answer here:
Syntax error due to using a reserved word as a table or column name in MySQL
(1 answer)
Closed 8 years ago.
I've been staring at this thing for a while now and I can't seem to figure out what the syntax error is. I've been in this situation before and last time it was something so unbelievably simple I felt stupid afterwards. But here's to another attempt:
//update database
$q = "
UPDATE
users
SET
id='$edit_id',
name='$edit_name',
bdm='$edit_bdm',
add='$edit_add',
pc='$edit_pc',
location='$edit_outletL',
style='$edit_outletS',
coName='$edit_coName',
coNum='$edit_coTel',
coEmail='$edit_coEmail',
password='$edit_pass'
WHERE
id='$query_title'
";
$edit_query = mysql_query($q) or die("Database Query Error: ". mysql_error());
Database Query 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 'add='Llancadle, Nr Barry', pc='CF62 3AQ', location='rural', style='food', coName' at line 1
You neeed to backquote add since it is a keyword:
`add` = ...
I think add is a reserved word in MySQL.
your problem is that "add" is a MySQL reserved word. See: http://dev.mysql.com/doc/refman/5.0/en/reserved-words.html. If you have a column named "add", escape it like this:
//update database
$edit_query = mysql_query("UPDATE users SET id='$edit_id', name='$edit_name', bdm='$edit_bdm', `add`='$edit_add', pc='$edit_pc', location='$edit_outletL', style='$edit_outletS', coName='$edit_coName', coNum='$edit_coTel', coEmail='$edit_coEmail', password='$edit_pass' WHERE id='$query_title'") or die("Database Query Error: ". mysql_error());
as bobby noted in a comment, add is a mysql reserved word
`add`='$edit_add'
will tell mysql you are talking about a column
Here's a very easy question for someone :)
Trying to update an SQL column with the following:
UPDATE [NameOfTable]
SET [HtmlContent] = 'a href="/sell-your-boat/"'
WHERE HtmlID = 123456
But am getting the following error message: Incorrect syntax near '/'.
I know it's because I need to escape the / character but hitting my head against the wall trying to find the answer because I am aware it's probably very simple!
Thank you
You don't need to escape slashes in a string in SQL. The only chracter that you need to escape is apostrophe (').
There is nothing wrong with the query that you are showing, so the only explanation is that the code that you are actually running does not look like that.
It doesn't make sense to have HTML-encoded quotation marks around a href attribute, so my guess is that the HTML code actually looks something like this:
<a href='/sell-your-boat/'>
Any apostrophes in the text would have to be encoded as double apostrophes when you put it in a string literal in the SQL code.
I don't know where the query is executed from, but a parameterised query would be preferrable if possible, as then you don't have to escape the text yourself, you just assign the text to the property value.
Like all the comments above, youd don't need to escape the /
I just did a quick sql test in sql server 2005 and didn't get an error message (see below)
We'll probably need more information than what you provided. Are you running this in Management studio, or is this sql being called in a .NET application, etc...
create table test (htmlid int, htmlcontent varchar(516))
insert into test select 123456 as htmlid, 'test' as htmlcontent
update test
set htmlcontent = 'a href="/sell-your-boat/"'
where htmlid = 123456
select * from test where htmlid = 123456
drop table test
my output
123456 a href="/sell-your-boat/"
