The lag and lead functions can fetch the first n rows of data (lag) and the latter n rows (leads) of the same field in the same query. This type of field can be implemented using table joins to the same table, although using lag and lead functions is more efficient.
Grammar:
LAG (Exp_str,offset,defval) over ()
Lead (Exp_str,offset,defval) over ()EXP_STR: Columns to fetchOffset: The first few rows of data after the offsetDefval: There are no default values that match the criteria

below: the first parameter: the content to be searched. In this example, it points to the A9 cell, that is, 7800; the second parameter: Compare the object region. In this example, the salary needs to be compared with the values in each cell in $ A $2: $ A $6; the third parameter: search result area. If it matches, the corresponding data in this area will be returned. In this example, the value corresponding to $ C $2: $ C $6 is returned. someone may ask, if the dictionary does not have a 780
