An aggregate function takes multiple rows (actually, zero, one, or more rows) as input and produces a single output. In contrast, scalar functions take one row as input and produce one row (one value) as output. An aggregate function always returns exactly one row, even when the input contains zero rows. Typically, if the input contained zero ...The number of rows backward from the current row from which to obtain a value. For example, an offset of 2 returns the expr value with an interval of 2 rows.

Supports ...IS [ NOT ] DISTINCT FROM. Compares whether two expressions are equal (or not equal). The function is NULL-safe, meaning it treats NULLs as known values for comparing equality. Note that this is different from the EQUAL comparison operator ( = ), which treats NULLs as unknown values. See also:Please note that the null value is a string instead of a json native null value like: ["Simon", "Sarah", null] This can cause problems in downstream systems working with that array, because the semantics of a string and of an actual null are very different.

To solve this we used function TRY_TO_NUMBER (column name, else put 0). So if there was some text found then it was changed to 0 .The row that follows the current row. The 2 in the call NTH_VALUE(i, 2) specifies the second row in the window frame (which, in this case, is also the current row). When the current row is the very first row in the window frame, there is no preceding row to reference, so FIRST_VALUE() returns a NULL for that row.
