PHP mySQL - Insert new record into table with auto

问题:

Wondering if there is a shorthand version to insert a new record into a table that has the primary key enabled? (i.e. not having to include the key column in the query) Lets say the key column is called ID, and the other columns are Fname, Lname, and Website

$query = "INSERT INTO myTable VALUES ('Fname', 'Lname', 'Website')";

回答1:

Use the DEFAULT keyword:

$query = "INSERT INTO myTable VALUES (DEFAULT,'Fname', 'Lname', 'Website')";

Also, you can specify the columns, (which is better practice):

$query = "INSERT INTO myTable
          (fname, lname, website)
          VALUES
          ('fname', 'lname', 'website')";

I prefer this syntaxis:

$query = "INSERT INTO myTable SET fname='Fname',lname='Lname',website='Website'";

回答3:

$query = "INSERT INTO myTable VALUES (NULL,'Fname', 'Lname', 'Website')";

Just leaving the value of the AI primary key NULL will assign an auto incremented value.

This is phpMyAdmin method.

$query = "INSERT INTO myTable
         (mtb_i_idautoinc, mtb_s_string1, mtb_s_string2) 
         VALUES
         (NULL, 'Jagodina', '35000')";

You can also use blank single quotes for the auto_increment column. something like this. It worked for me.

$query = "INSERT INTO myTable VALUES ('','Fname', 'Lname', 'Website')";
