Discovering Existing Collections with SODA for In-Database JavaScript

You can use SodaDatabase.getCollectionNames() to fetch the names of all existing collections for a given SodaDatabase object.

If the number of collections is very large, you can limit the number of names returned. Additionally, the lookup can be limited to collections starting with a user-defined string as demonstrated by Example: Filtering the List of Returned Collections.

Example: Fetching All Existing Collection Names

This example prints the names of all existing collections using the method getCollectionNames().

export function printCollectionNames(){
  // loop over all collections in the current user's schema
  const allCollections = soda.getCollectionNames();
  for (const col of allCollections){
    console.log(`- ${col}`);
  }
}

Example: Filtering the List of Returned Collections

This example limits the results of getCollectionNames() by only printing the names of collections that begin with a user-defined string, startWith.

export function printSomeCollectionNames(numHits, startWith) {

  // loop over all collections in the current schema, limited
  // to those that start with a specific character sequence and
  // a maximum number of hits returned
  const allCollections = soda.getCollectionNames(
    {
      limit: numHits,
      startsWith: startWith
    }
  );
  for (const col of allCollections){
    console.log(`-${col}`);
  }
}
