Hi

I have two identical tables.
I use one as a temporary table for importing data to, so it can be manipulated before updating the real table.

I've tried updaing the real table with:

 string SQL = "INSERT INTO ActualReadings " +
                                " (Date,Time,Thing1, thing2, thing3)" +
                        "SELECT  "  +
                        "(Date,Time,Thing1, thing2, thing3)" +
                            " FROM TempReadings";

                //Declare the Command
                SqlCommand cmd = new SqlCommand(SQL, conn);

                //Make the connection
                conn.Open();
               
                //Execute query
                int NumRows = 0;
                NumRows = cmd.ExecuteNonQuery();
               
but get an error, that I believe is related to the fact both tables have an identity column (ID).

What's the best way around this?

Many thanks.

Hi

Your SQL looks OK to me, you're not trying to insert an identity value unless one of your fields Date, Time, Thing1 etc are an identity field.

What is the error you're getting?

Incorrect syntax near ','.
 which is refering to the first "," after the word select.

i'm sure it's something to do with both tables having identity columns (ID) which I'm not inserting but obviuosly want to generate.
The column is set up correctly, but just doesn't want to work on a bulk inport.

Try sticking [ and ] around Date and Time, as they are reserved words, and remove those brackets:

string SQL = "INSERT INTO ActualReadings " +
                                " ([Date],[Time],Thing1, thing2, thing3)" +
                        "SELECT  "  +
                        "[Date],[Time],Thing1, thing2, thing3 " +
                            " FROM TempReadings";

Open in new window


Hopefully that will fix it

Many thanks- I noticed the brackets just  before you replied and removing them fixed it.

Yep, simple as that, not an issue with identity. I'm glad to have helped
