| - | ====== Omnidex SQL Function: $CURRENT_ROW ====== | ||
| - | ===== Description ===== | ||
| - | The $CURRENT_ROW function return the current row number for the result set. The first row returned from a SELECT statement is given a value of 1, and each successive row is incremented by one. This is done as the last step of a statement, and so $CURRENT_ROW can only be used as a select-item. It cannot be used in the WHERE, GROUP BY, ORDER BY or HAVING clauses. | ||
| - | |||
| - | The $CURRENT_ROW should not be confused with the $ROWID. The $ROWID comes from the underlying database, where $CURRENT_ROW is simply the current row number of the result set. | ||
| - | |||
| - | This function returns an INTEGER datatype. | ||
