Converting SQL to Javascript API

Select a set of columns from a single table with where, order by, and limit clauses.

select first_name, last_name, team_id, age from players
where age between 20 and 24 and team_id <> 'STL'
order by last_name, first_name desc
limit 20
const { data, error } = await supabase
.from('players')
.select('first_name,last_name,team_id,age')
.gte('age', 20)
.lte('age', 24)
.not('team_id', 'eq', 'STL')
.order('last_name', { ascending: true }) // or just .order('last_name')
.order('first_name', { ascending: false })
.limit(20)

Select all columns from a single table with a complex where clause: OR AND OR

select * from players
where ((team_id = 'CHN' or team_id is null) and (age > 35 or age is null))
const { data, error } = await supabase
.from('players')
.select() // or .select('*')
.or('team_id.eq.CHN,team_id.is.null')
.or('age.gt.35,age.is.null') // additional filters imply "AND"
.not('team_id', 'eq', 'STL')

Select all columns from a single table with a complex where clause: AND OR AND

select * from players
where ((team_id = 'CHN' and age > 35) or (team_id <> 'CHN' and age is not null))
const { data, error } = await supabase
.from('players')
.select() // or .select('*')
.or('and(team_id.eq.CHN,age.gt.35),and(team_id.neq.CHN,.not.age.is.null)')

Get a count of rows, but don't return any data.

select count(*) from players
where team_id = 'NYM'
const { data, error } = await supabase
.from('players')
.select('*', { count: 'exact', head: true }) // exact, planned, or executed
.eq('team_id', 'NYM')
