g_and(G;S;X)

Returns a boolean value indicating whether all values within a given group are true.

Function type

Vector only

Syntax

g_and(G;S;X)

Input

Argument Type Description
G any A space- or comma-separated list of column names

Rows are in the same group if their values for all of the columns listed in G are the same.

If G is omitted, all rows are considered to be in the same group.

If any of the columns listed in G contain N/A, the N/A value is considered a valid grouping value.

S integer The name of a column in which every row evaluates to a 1 or 0, which determines whether or not that row is selected to be included in the calculation

If S is omitted, all rows will be considered by the function (subject to any prior row selections).

If any of the values in S are neither 1 nor 0, an error is returned.

X
  • integer
  • big integer
A column name
Note: This column can only contain a 1 or 0 value (or is a computed column that evaluates to such) for every row.

N/As in X are ignored (i.e., the result is whether all non-N/A values within a given group are true).

Note: Support for columns of type big integer available as of version 11.25.

Return Value

For every row in each group defined by G (and for those rows where S=1, if specified), g_and returns an integer value of 1 if all of the values are equal to 1 in the column listed in X that are in the same group as that row.

If all values for a particular group are N/A, the result is 1.
