Hi,

I am inserting records into ms access using vb.net.

insert into data(F01,F02)values(" & F01(k) & "," & IIf(Double.IsNaN(F01TA(k)), DBNull.Value, F01TA(k)) & ")"

Showing syntax error in the insert statement.

the output query is like below

insert into Data(F01,F02)values(221,);

Please share your ideas...

Thanks,
Sivakumar.M.

check the value of the given parameters... your generated query probably like ...
....Values(1,2,,3)

What is the Error that you are getting ?

Your insert is incorrect, Your expected number of parameters is less than the Supplied Parameters.

When you concatenate DBNull.Value into your query expression, it calls the DBNull.ToString method. This is defined to return an empty string, so your insert statement is missing a parameter after the final comma.

Use the literal "null" in your SQL insert instead of DBNull.Value, that should work. Or use a DbCommand with query parameters, as someone else suggested.

I will be using both MSSQL and MySQL data bases.

MSSQL you can create a stored procedure to do the insert and then schedule a job to execute the procedure when required.

MySQL - I don't know.

As suggested you could use a windows service to do both inserts.

Thanks for the reply.Here the constraint is I cannot use Windowse services.So, I will schedule a job whichi will fire on each day at specific time.In this job i will call the SP which will insert or update the desired record.I hore in MYSQL ALSO it will works.Right....

Thanks,

If MySQL does not support jobs then you may be able to trick SQL Server into doing the job on MySQL as a remote server or a linked server, nasty but it may be possible.

Oho..This will create more problem for me.I cannot use SQLSERVER to trigger MYSQL.I canot use windowse services.But I need the auto insert action...Is there any other option in MySQl which is similar to MSSQL jobs feature.Please guide me.

Thanks in advance,

MySQL has an event scheduler which can be used to fire off tasks at specified times or intervals.

Triggers execute in response to certain events when INSERT, UPDATE or DELETE

So in this case I cant use triggers..right?

I think you can create a stored procedure for the insertion and call it from a SQL job that's it;

Hi uglyeyes--
You have been a member long enough that CodeProject is not here to answer generic questions such as these. Your question is one where most would probably tell you to "just Google it." Creating a basic database and its tables is part of the learning process. Sit down, take some time, and think it out.

Back in the blog beatch!

How to create table called employee, timecard etc in some database?

or

You are looking for guidance related to database design?
