between :: SExp -> SExp -> SExp -> SExp #

scope :: SExp -> SExp -> SExp #

scoped :: SExp -> SExp -> SExp #

textInfix :: SExp -> SExp -> SExp #

Is text a contained in text b?

nullIfEmpty :: SExp -> SExp #

Replace empty string with NULL

seekBackIgnoreNulls :: SExp -> Int -> WOver -> SExp #

Use nthValue under the hood with IgnoreNulls, set window frame to start at current row (so nth-value can index) and flip the ordering in given OVER clause so that it semantically behaves like lag but with ignore nulls functionality.

It will start with current row, so setting to 1 will just return current row's value.

seekForwardIgnoreNulls :: SExp -> Int -> WOver -> SExp #

Same deal as lagIgnorenulls but doesn't need to flip the ordering in OVER clause as lead and nthValue both naturally operate in ascending order.

lagIgnoreNulls :: SExp -> Int -> WOver -> SExp #

BigQuery can't ignore nulls while lagging/leading. Use the seekBackignorenulls machinery intelligently to mimic a proper lag with ignore nulls.

percentDiff :: SExp -> SExp -> SExp #

percent difference of a over b with typecast to Double

humanAge :: SExp -> SExp -> SExp #

Calculates the year-based human age given a "current date" and a date in the past. Returns float-based age. DATE_DIFF(CURRENT_DATE, cast('1990-01-01' as date), YEAR) + IF(EXTRACT(DAYOFYEAR FROM CURRENT_DATE) < EXTRACT(DAYOFYEAR FROM cast('1990-01-01' as date)), -1, 0)
