Hi
I don't know what I'm doing wrong. I cannot properly type results when the option rowsAsArray is enabled. My SQL returns an array of arrays that contains only one string eg:
rowsAsArray
// connection.promise().query("SHOW TABLES LIKE 'table_%';"); [ [ 'table_1'], [ 'table_2'], [ 'table_3'], [ 'table_4'], ]
I want to flat this result in my helper function but TS complaints about types mismatch. See example below
const listTablesSql = "SHOW TABLES LIKE 'table_%';" async strictTypeInQuery(): Promise<string[]> { // error: `Type 'string' is not assignable to type 'RowDataPacket'` const [rows] = await connection.promise().query<string[]>({sql: listTablesSql, rowsAsArray: true}); return rows.flat(1); } async inferType(): Promise<string[]> { // error: `Type 'string' is not assignable to type 'RowDataPacket'` const [rows] = await connection.promise().query({sql: listTablesSql, rowsAsArray: true}); return rows.flat(1); // TS:error `Type 'RowDataPacket' is not assignable to type 'string'.` }
Can you help me and point what I'm doing wrong?
