Today, when I was studying MySQL, I found that when I created a database table, the table only corresponds to one. frm file, but there were no. MYD and. myi files.
After some searching, I found that the default database storage engine used for my local MySQL storage table is InnoDB, but the InnoDB Storage engine is not generated. MYD and. myi file.
To generate the. MYD and. myi files, you only need to explicitly specify the database storage engine

is no problem to create a new record in this way, but if you create two records consecutively, the form will report: FRM-40102: The record must first be entered or deleted. That is, the status of the last record is problematic, but where is the problem?After many tests, it is not difficult to find: if there is already a record in the block, then using the above code will not report the error, but if the block is originally empty, is a new block, then
When assigning values to items with lov, a dialog box for the FRM-40212 may pop up.
Solution: add the following statement after the value assignment statement:
Set_item_property ('detail. locator ', item_is_valid, property_true );
'Detail. locator' is an item with lov.
