Delphi TmysqlQuery

[question]

Hi,
I am using Tmysqlquery and TmySqlUpdateSQL to update(insert/delete/modify) the database concring user input, but i get the error "you have an error in your sql syntax near 'OC2000000A000000201' EmySqldatabase error"

i have checked several times the query and database connection, everything is fine but i dont have any idea why i get this error
do you have any idea?

Without the complete Query it's very hard to impossible to help you.

The problem is not the databaseconnection. The problem is the SQL-Query you are using.

LOG it for debugging purposes. Or maybe post the query here...

[question]

as i have used tmysqlquery instead TQuery ,therefore I have one idea, it can happend becasue of tmysqlquery component?

here is the code for insert (it is from dfm)

Code:

insert into TableAdd
  (Name, Address, Phone, Emial, Date)
values
  (:Name, :Address, :Phone, :Emial, :Date)

modify

Code:

update TableAdd
set
  Name= :Name,
  Address= :Address,
  Phone= :Phone,
  Emial= :Emial,
  Date= :Date
where
  ID = :OLD_ID

delete

Code:

delete from TableAdd
where
  ID = :ID

What happens when you quote the fieldnames?

Code:

insert into TableAdd
  (`Name`, `Address`, `Phone`, `Emial`, `Date`)
values
  (:Name, :Address, :Phone, :Emial, :Date)

At least "Date" is quite surely a reserved word because there is a corresponding data type.

[question]

I have tried as you suggested even i have also tried by changing the name of the date field

Code:

insert into TableAdd
  (`Name`, `Address`, `Phone`, `Emial`, `Date`)
values
  (:Name, :Address, :Phone, :Emial, :Date)

but still have the same error, by the way,how can i check System.DateTime value and MySql.Data.Types.MySqlDate, maybe the datetime of the system and the mysqlDate is not matching, its just my idea,what do you think?

[DeddyH]

SQL-Parameters are usually parsed automatically. Maybe your field is a timestamp instead of a Date/DateTime? It is hard to find a solution when you don' t know either the table structure nor the Delphi-code used to execute your queries.

[question]

the field 'Date' is a DateTime field,

[Lemmy]

Hi,

please try this one:

  xxx.ParamByName('Date').AsString := FormatDateTim('yyyy-mm-dd', YourDateValue);
cu

[question]

the querystring is done by using dfm with field and parameter
how can i use

Code:

xxx.ParamByName('Date').AsString := FormatDateTim('yyyy-mm-dd', YourDateValue);
