INSERT command for auto increment field in access from asp.net website

Question

I've got my primary key set to auto increment in my access database.

How do I specify that I want the primary key to have the next available value?

eg

OleDbCommand cmd = new OleDbCommand("INSERT into Table VALUES (?,"string","string");", conn);

thanks!

Answer 1

If it is set to auto increment you dont have to specify a value for it

just do

OleDbCommand cmd = new OleDbCommand("INSERT into Table VALUES ("string","string");", conn);

although one would prefer you write the column names explicitly

Answer 2

If the database field is already set to auto-incremente, then you don't need to worry about it!

Just insert the other fields! INSERT into Table VALUES ("string","string")

Answer 3

If you have a table as such:

Table

 ID    SomeString     SomeString2

where ID is the primary key, then you'd not need to specify the value for the primary key. It would be "auto-incremented" as you have specified that.

So you'd enter:

OleDbCommand cmd = new OleDbCommand("INSERT into Table (SomeString, SomeString2) VALUES ('stringA','stringB')", conn);

Note : Its a good practice to always mention the column names when performing insertion of records.

Hope this helps!!!

Answer 4

您可以跳过它：

OleDbCommand cmd = new OleDbCommand("INSERT into Table VALUES ("string","string");", conn);
