- You need a list of the selected fields, the tables from which data will be selected, and the names of the variables to where data will be downloaded.
- The three ways are: FOR ALL ENTRIES, SELECT...ENDSELECT, and JOIN.
- The ways to read data from tables are as follows:
-
- Get only the required rows from a table.
- Get only the required columns from a table.
- Do not use more reads than necessary.
- Use local buffers and indexes.
