I'm attempting to implement the node Google Spanner library (v6.6.0) and I'm running into an issue with parameterized sql.
const {Spanner} = require('@google-cloud/spanner');
async function doStuff() {
// Creates a client
const spanner = new Spanner({
projectId: "<my_project_id>",
});
// Gets a reference to a Cloud Spanner instance and database
const instance = spanner.instance("<my_instance>");
const database = instance.database("<my_db>");
const query = {
sql: `SELECT id, name, text
FROM greetings WHERE name = 'Name'`,
};
const [results] = await database.run(query);
console.log("Results: " JSON.stringify(results));
}
doStuff().then(() => console.log("Complete"));
This is not parameterized, and when I run this I get the following output:
Results: [{"id":"8694b2b9-add0-4024-bb22-bd711bbda9d4","name":"Name","text":"New Message"}]
Complete
as expected.
However, if I update the query object to use parameterization, like so:
const query = {
sql: `SELECT id, name, text
FROM greetings WHERE name = @Name`,
params: {
Name: 'Name'
};
I get the following error:
node:internal/process/promises:288
triggerUncaughtException(err, true /* fromPromise */);

That seems odd that the parameter names must be named p1, p2, etc, because it is not the case in the Google Cloud Spanner docs, but I went ahead and tried it anyway.
So, I convert the query object like so (as instructed by the error):
const query = {
sql: `SELECT id, name, text
FROM greetings WHERE name = @p1`,
params: {
p1: "Name"
}
};
Now I get the following error:
node:internal/process/promises:288
triggerUncaughtException(err, true /* fromPromise */);

I can't seem to figure out how to get parameterized sql to work on a database.run() function call. Am I doing something wrong or have I set my database up incorrectly? I'm using the postgresql dialect if that makes a difference.
CodePudding user response:
I'm using the postgresql dialect if that makes a difference.
Yes, that makes the difference. PostgreSQL-dialect databases uses the PostgreSQL SQL dialect. That means that queries must use PostgreSQL style query parameters, which is $1, $2, ...
. So your query should be:
const query = {
sql: `SELECT id, name, text
FROM greetings WHERE name = $1`,
params: {
p1: 'Name'
};
See https://github.com/googleapis/nodejs-spanner/blob/02c6e599a7b744a5c610c8d801229c7299abb668/samples/pg-query-parameter.js#L51 for a full sample.
