Mimic COALESCE behaviour using groups of conditions when querying with Prisma client - prisma

Question

I'm trying to replace a SQL query (Postgres) with a Prisma client query, and I'm struggling to implement this COALESCE logic:
COALESCE(date_1, date_2,'1970-01-01 00:00:00') <= CURRENT_TIMESTAMP
As fas as I can tell, Prisma client doesnt currently support COALESCE, so there's no simple way for me to do this. I think I have to group conditions together to replicate this. The logic would be along the lines of:
ANY of the following
date_1 <= CURRENT_TIMESTAMP
ALL of the following
date_1 IS NULL
date_2 <= CURRENT_TIMESTAMP
ALL of the following
date_1 IS NULL
date_2 IS NULL
But I cant work out how to group conditions like this using the Prisma client, because you cant have multiple AND's within an OR (or vis versa):
const records = await client.thing.findMany({
where: {
OR: {
date_1: { lte: new Date() },
AND: {
date_1: null,
date_2: { lte: new Date() }
},
AND: { // <--- Cant do this, because we've already used AND above
date_1: null,
date_2: null
}
}
},
});
We obviously cant repeat the same object key twice, so I cant have two AND statements at the same level, otherwise I get the error:
An object literal cannot have multiple properties with the same name
I'm probably missing something obvious, but I cannot work out how to achieve groups of conditions like this. If anyone can help I'd appreciate it!
I should mention that I'm using:
nodejs v14.19.1
prisma ^3.14.0

Answer 1

I was indeed missing something obvious. We can pass in an array of groups to an AND or OR group, like so:
const records = await client.thing.findMany({
where: {
OR: {
date_1: { lte: new Date() },
AND: [
{
date_1: null,
date_2: { lte: new Date() }
},
{
date_1: null,
date_2: null
}
]
}
},
});
