CodePudding user response:

refer to the second floor zcwthy response:

how to filter, I'm not using field content for a condition, but the record number=n as the condition, how to write the filter conditions?

You this is in relative terms, prone to errors, or with its ID or other field to filter,
If as long as the table 5 records, or use it ID field to filter or another table in SQL statements,

CodePudding user response:

Article 5 the data in the database only display?
Assume the table called tablename, the only key to a

Select * from tablename
Adoq. First;
Adoq. Next;
Adoq. Next;
Adoq. Next;
Adoq. Next;

Select * from tablename where a=adoq [' a ']
Adoq. Open
(need to display the DBGrid adoq)
