I've only seen this when there's a nested in (which you can get around with a cte). There also seems to be something going on with whether or not there's whitespace after the in:

sql.unsafe(`drop table if exists t; create table t as (select 1 x);`).then(() => {
  // success: not nested
  sql`select x from t where x in ${sql([1])}`
    .then((data) => console.log(data)) // Result [{x: 1}]
    .catch((err) => console.log(err.message));

  // failure: nested without space after outer 'in'
  sql`select x from t where x in(select x from t where x in ${sql([1])})`
    .then((data) => console.log(data))
    .catch((err) => console.log(err.message)); // str.replace is not a function

  // failure: nested without space after inner 'in'
  sql`select x from t where x in (select x from t where x in${sql([1])})`
    .then((data) => console.log(data))
    .catch((err) => console.log(err.message)); // str.replace is not a function

  // success: space after outer and inner 'in'
  sql`select x from t where x in (select x from t where x in ${sql([1])})`
    .then((data) => console.log(data)) // Result [{x: 1}]
    .catch((err) => console.log(err.message));
});

@Nepherpitou just tried exactly your example and didn't see any issue. Do you have something I can repro?

[porsager]

Very nice tests @rytido !! Thank you - I'll look at fixing those and including your tests.

For what it worth, I had encountered this issue too and the comment by @rytido helped me work around it. This was my original query:

const val1 = "1";
const valuesArray = [
  ["2", "3", "4"]
];

sql`
    DELETE FROM my_table
    WHERE
        col1 = ${val1} AND
        (col2, col3, col4) IN (${sql(valuesArray)})
`;

Removing the space directly after the "IN" made it work:

sql`
    DELETE FROM my_table
    WHERE
        col1 = ${val1} AND
        (col2, col3, col4) IN(${sql(valuesArray)})
`;
