Performing record-level operations with table functions and expressions
Many table functions and associated expressions lead to row-level results instead of column-level results. When we say row level, it means these functions return key values of the rows. You can then access a record of a table with that record’s key value when the column type is referenced. Let us look at the most used table functions that work at the record level. We will also learn about a few table functions that work at the column level:
Table 4.43 – Using the MAXROW() and MINROW() functions
Let us learn about the ORDERBY() function next, which sorts the records of a table in ascending or descending order:
Table 4.44 – Using the ORDERBY() function to sort a table or slice records
Having understood the main row-level functions, let us next understand the important differences between column-level and row-level functions of a similar nature...
