When attempting to run this query in Node.JS/Express using MySQL, I get an error.
Without the line "created DATETIME,\n" the code works perfectly. When including that line, or any variation of it (such as trying to attempt to put a default date of the current time), it also says the exact same error.
"You have an error in your SQL syntax; check the ... (redacted) ... for the right syntax to use near '' at line 4"
var create_elements =
"CREATE TABLE elements(\n" +
"id INT NOT NULL AUTO_INCREMENT,\n" +
"googleID VARCHAR(60),\n" +
"created DATETIME,\n"
"title VARCHAR(300),\n" +
"body TEXT,\n" +
"type ENUM('blog', 'issue'),\n" +
"PRIMARY KEY (id)\n" +
");";
There is no plus sign after your new string snippet containing the DATETIME line, so the resulting string does not contain the remaining elements or closing parenthesis and is syntactically invalid.

I'm attempting to execute a simple query that inserts two names, "self.player1", and "self.player2" as VARCHAR datatypes into a table on a MySQL server version 8.0.31. When I call a custom-built function called "execute_query()" provided below, I receive the following error in my terminal:
Error: '1054 (42S22): Unknown column 'Jo' in 'field list''
Function Definition of "execute_query()":
def execute_query(self, query):
''' This function takes SQL queries stored
in Python as strings and passes them
to the "cursor.execute()" method to
execute them on the server'''
cursor = self.connection.cursor()
try:
cursor.execute(query)
self.connection.commit() # Implements commands detailed in SQL queries
print(query + "Query successful")
except Error as err:
print(f"Error: '{err}'")
The names of the attributes are "player_1" and "player_2", and the values to be inserted are assigned to variable names "self.player1", and "self.player2" as shown below.
query = "USE " + self.db_obj.db_name + ";"
self.db_obj.execute_query(query)
query = "INSERT INTO `match`(player_1, player_2) VALUES (" + self.player1 + "," + self.player2 + ");"
It is important to mention that the issue is not with the "execute_query()" function as I have been able to successfully execute other queries. Additionally, I have run through numerous other similar issues on this discussion forum and have tried dropping triggers, changing secure file priviliges, and hardcoding the value of my entries into the query as opposed to concatenating the values to other strings to produce the resultant query, and have not had any luck.
The design of the table, match is provided below (Note: I was not able to write out the contents of this query to a text file using the following command:
SELECT * FROM `match`
INTO OUTFILE "test.txt";
as I received this error:
The MySQL server is running with the --secure-file-priv option so it cannot execute this statement
The query that I used to generated the table in the image below is:
DESCRIBE `match`;
Your error says : Error: '1054 (42S22): Unknown column 'Jo' in 'field list''.
The word 'Jo' in the error is not a field name but a player name. You need to modify your query to :
query = "INSERT INTO `match`(player_1, player_2) VALUES ('" + self.player1 + "','" + self.player2 + "');"
Since string values need to be between single quotes.
when trying to update my mysql database-column with following sql command
UPDATE db.vendor_horses SET image='{"images":["' + image + '"]}';
I get following error:
UPDATE db.vendor_horses SET image='{"images":["' + image + '"]}' Error Code: 1292. Truncated incorrect DOUBLE value: '{"images":["' 0.00028 sec
I can't figure out what's wrong..
in mysql + is not valid concatenation sign. (MySQL concatenation operator)
you should use CONCAT function.
UPDATE db.vendor_horses SET image= CONCAT('{"images":["', image, '"]}';
I have a column in a text-file with dates like this: 20131207.
I and trying to convert the date like this but everything I have tried has failed.
Here is my code: I have modified it many times to fix this problem.
(LEN(TRIM(MyDate)) < 8) || (TRIM(MyDate) == " ") ||
(ISNULL(MyDate)) ? NULL(DT_DBDATE) :
(DT_DBDATE)(SUBSTRING(TRIM(MyDate),1,4) + "-" +
SUBSTRING(TRIM(MyDate),5,2) + "-" + SUBSTRING(TRIM(MyDate),7,2))
Where am I going wrong?
I checked Retain Null Values in the Flat Source Task.
Update: Here is the error message:
The conditional operation failed.
The "Rename Columns (My_Table)" failed because error code 0xC0049063 occurred,
and the error row disposition on "Rename Columns (My_Table).Outputs[Derived
Column Output].Columns[MyDate]" specifies failure on error. An error occurred
on the specified object of the specified component. There may be error
messages posted before this with more information about the failure.
I need to convert the data in the text file to date, from 20131207 to 2013-12-07 but I want to insert null if the data in the text file is less then 8 in length or cannot be converted to date.
try this:
add a new flat file source then add a derived column then in expression do this
`LEFT(date,4) + "-" + SUBSTRING(date,5,2) + "-" + RIGHT(date,2)`
the package :
with output like this :
Trim(MyDate)==" " should be Trim(MyDate)==""
I want to insert a value "5/27/2013 16:42:37.490000" (Read from a flat file (DT_STR)) into a column(datetime) of SQL Server table . If I try to cast it with (DT_DBDATE) or DT_DBTIMESTAMP in a derived column , it gives an error .
[Derived Column [130]] Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "component "Derived Column" (130)" failed because error code 0xC0049064 occurred, and the error row disposition on "output column "Derived Column 1" (155)" specifies failure on error. An error occurred on the specified object of the specified component. There may be error messages posted before this with more information about the failure.
How can I go about it ?
Thanks
The value is a datetime2 type .AFAIK SSIS doesn't support datetime2 .You need to store it in database as string and then update the column by converting it to datetime2.
Here is Microsoft Connect Issue
Update: Using DT_DBTIMESTAMP2 you can convert the string to proper datetime format
The below code works perfectly fine in Derived Column
(DT_DBTIMESTAMP2,7)"2013-5-27 16:42:37.490000"
7 is the precession here .The above code won't work if the format of datetime is different.For example MM/DD/YYYY HH:mm:ss.ffffff .
However you can use Script component and pass array of different datetime formats to Datetime.ParseExact function
Step1: Drag a Script component and create a new output column of DT_DBTIMESTAMP datatype and name it as NewDate.
Step2: Write the below C# code
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
string[] format = new string[] { #"M/dd/yyyy HH:mm:ss.ffffff",
#"MM/dd/yyyy HH:mm:ss",
#"M/d/yyyy HH:mm:ss" ,
#"M/dd/yyyy HH:mm:ss.ffffff",
#"MM/dd/yyyy HH:mm:ss.ffffff",
#"M/d/yyyy HH:mm:ss.ffffff"};
DateTime dt = DateTime.ParseExact(Row.Date,
format ,
CultureInfo.InvariantCulture,
DateTimeStyles.None);
Row.newDate = dt;
}
I won't say it's the perfect solution, but just a workaround.
Format the input and then insert. The formatted data after using the below expression works well with either datetime or datetime2.
SUBSTRING(TMS_CREAT,(FINDSTRING(TMS_CREAT,"/",2) + 1),4) + "-" + SUBSTRING(TMS_CREAT,1,(FINDSTRING(TMS_CREAT,"/",1) - 1)) + "-" + SUBSTRING(TMS_CREAT,(FINDSTRING(TMS_CREAT,"/",1) + 1),2) + SUBSTRING(TMS_CREAT,(FINDSTRING(TMS_CREAT,"/",2) + 5),16)

My expression is:
(DT_DBTIMESTAMP)(SUBSTRING(EVENT_D,7,4) + "-" +
SUBSTRING(EVENT_D,4,2) + "-" +
SUBSTRING(EVENT_D,1,2) + EVENT_T)
My original data are in this sequence:
EVENT_D: DD/MM/YYYY
EVENT_T: HH:MM:SS
Any help are appreciated. I have try changing my expression numerous time but still fails.
I suspect that there are some date time values which are not in the correct format .So SSIS throws error while parsing them .
In order to find to incorrect date time value from your source table try to redirect the error rows from Derived Transformation and check the incorrect data using a data viewer
The problem with substring values are if the string data are not in the correct format then the Derived Transformation will throw error .
In your OLEDB source component try to write the sql and get only the correct datetime values
Ex:
Select col1,
case when isDate(EVENT_D) = 1 THEN EVENT_D ELSE NULL
END as [EVENT_D],
Col2,EVENT_T,other columns
from yourTable
in your derived transformations use your code to convert into DT_DBTIMESTAMP type .
Else Try to use a script component and parse the EVENT_D and EVENT_T values and convert to datetime values. No need to use Derived column with all those substring values
create a New Output column Valid_D with the datatype as DT_DBTIMESTAMP.Select the 2 input columns EVENT_D and EVENT_T in the available input Columns in Script Transformation Editor
VB.NET code
Dim result As DateTime
If DateTime.TryParseExact(Row.EVENT_D, "dd/MM/yyyy",
Nothing, Globalization.DateTimeStyles.None, result) Then
Row.ValidD = result.Add (TimeSpan .Parse (Row.EventT ) );
End If
C# code
DateTime result;
if (DateTime.TryParseExact(Row.EventD, "dd/MM/yyyy",
CultureInfo.InvariantCulture, DateTimeStyles.None,out result))
{
Row.ValidD = result.Add (TimeSpan .Parse (Row.EventT ) );
}
Now you can use Valid_D column which is of DateTime type in your subsequent transformations
Update : The problem with your syntax is you cannot add date+ time in the string format . You need to parse individually both EVENT_D and EVENT_T .
(DT_DBTIMESTAMP)(SUBSTRING(EVENT_D,7,4) + "-" +
SUBSTRING(EVENT_D,4,2) + "-" +
SUBSTRING(EVENT_D,1,2) + EVENT_T)
So your syntax is not valid.
The isDate function shows NULL for 30/04/2012 because as per MSDN
The return value of ISDATE depends on the settings set by
SET DATEFORMAT, SET LANGUAGE and Configure the default language
Server Configuration Option.
but it returns 1 for the value 01/05/2012 and 02/05/2012 because it takes as MM/dd/YYYY
so the 1st date is Jan 5th 2012 instead of May 1st 2012
So the soultion is use script component and parse these values into valid date and time and then use it in your subsequent transformations .
Please check my script transformation code above
Update 2:
I think your using SSIS 2005 .The code should be
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Dim result As DateTime
If DateTime.TryParseExact(Row.EVENTD, "dd/MM/yyyy", Nothing, Globalization.DateTimeStyles.None, result) Then
Row.ValidD = result.Add(TimeSpan.Parse(Row.EVENTT))
End If
End Sub
after Script transformation ,you don't need to use Derived component .The result obtained in the column Valid_D contains the valid value which is of datetime format
If you wanted to do this without a script, you could have just changed your expression from
(DT_DBTIMESTAMP)(SUBSTRING(EVENT_D,7,4) + "-" +
SUBSTRING(EVENT_D,4,2) + "-" +
SUBSTRING(EVENT_D,1,2) + EVENT_T)
to
(DT_DBTIMESTAMP)(SUBSTRING(EVENT_D,7,4) + "-" +
SUBSTRING(EVENT_D,4,2) + "-" +
SUBSTRING(EVENT_D,1,2) + " " + EVENT_T)
Not having the space between the date and the time portions is what was most likely causing your original error. You were getting
2012-04-3012:25:37
instead of
2012-04-30 12:25:37
I faced the same problem while converting a string containing date to datetimestamp field. It is all due to spaces in the field.
So we need to check for space and then convert it to datetimestamp.
Below is the expression for the same.
LEN(TRIM([Field1])) == 1 ? NULL(DT_DBTIMESTAMP) : (DT_DBTIMESTAMP)(SUBSTRING([Field1],1,4) + "-" + SUBSTRING([Field1],5,2) + "-" + SUBSTRING([Field1],7,2) + " " + SUBSTRING([Field1],10,2) + ":" + SUBSTRING([Field1],12,2))
