Updating multiple rows causes type error

I'm following the guide posted here https://orm.drizzle.team/learn/guides/update-many-with-different-value regarding updating multiple rows at once. My data is similar, but not the same:

const inputs = [
  {
    id: 9,
    order: 2,
  },
  {
    id: 10,
    order: 1,
  },
];

const inputs = [
  {
    id: 9,
    order: 2,
  },
  {
    id: 10,
    order: 1,
  },
];

The raw output is:

{
  sql: '(case when "routes"."id" = $1 then $2 when "routes"."id" = $3 then $4 end)',
  params: [ 9, 2, 10, 1 ]
}

{
  sql: '(case when "routes"."id" = $1 then $2 when "routes"."id" = $3 then $4 end)',
  params: [ 9, 2, 10, 1 ]
}

Unfortunately, this causes a type error when being submitted:

Database Error: error: column "order" is of type integer but expression is of type text

Database Error: error: column "order" is of type integer but expression is of type text

I assume this is because the sql is being converted to something like this:

case when "routes"."id" = 9 then "2"

case when "routes"."id" = 9 then "2"

therefore it's being recognized as a string whenever it's submitted to the database. But I could be wrong. Is it possible to cast this value somehow or otherwise inform Drizzle that it's supposed to be an integer and not a string?

What does the full update query look like? In Typescript (raw SQL would be nice too

How do I get the raw SQL?

Mario564•6mo ago

Sorry, I meant something like the "raw output" you provided above, but for the full query (or something close to the full query)

dsf_2OP•6mo ago

const sqlChunks: SQL[] = [];
const ids: number[] = [];

sqlChunks.push(sql`(case`);

for (const route of updateInfo) {
  sqlChunks.push(sql`when ${routes.id} = ${route.id} then ${route.order}`);
  ids.push(route.id);
}

sqlChunks.push(sql`end)`);

const finalSql: SQL = sql.join(sqlChunks, sql.raw(" "));

await db
  .update(routes)
  .set({ order: finalSql })
  .where(inArray(routes.id, ids));

const sqlChunks: SQL[] = [];
const ids: number[] = [];

sqlChunks.push(sql`(case`);

for (const route of updateInfo) {
  sqlChunks.push(sql`when ${routes.id} = ${route.id} then ${route.order}`);
  ids.push(route.id);
}

sqlChunks.push(sql`end)`);

const finalSql: SQL = sql.join(sqlChunks, sql.raw(" "));

await db
  .update(routes)
  .set({ order: finalSql })
  .where(inArray(routes.id, ids));

This is the code It's the same as what is in the linked guide working on the raw, one min

Try casting the whole case statement to integer, like so:

sqlChunks.push(sql`end)::integer`);

sqlChunks.push(sql`end)::integer`);

It worked!! You are a legend thank you so much!
