type Querier

type Querier interface {
	// CountAuthors returns the number of authors (zero params).
	CountAuthors(ctx context.Context) (*int, error)
	// CountAuthorsBatch enqueues a CountAuthors query into batch to be executed
	// later by the batch.
	CountAuthorsBatch(batch genericBatch)
	// CountAuthorsScan scans the result of an executed CountAuthorsBatch query.
	CountAuthorsScan(results pgx.BatchResults) (*int, error)

	// FindAuthorById finds one (or zero) authors by ID (one param).
	FindAuthorByID(ctx context.Context, params FindAuthorByIDParams) (FindAuthorByIDRow, error)
	// FindAuthorByIDBatch enqueues a FindAuthorByID query into batch to be executed
	// later by the batch.

	// DeleteAuthorsByFullName deletes authors by the full name (three params).
	DeleteAuthorsByFullName(ctx context.Context, params DeleteAuthorsByFullNameParams) (pgconn.CommandTag, error)
	// DeleteAuthorsByFullNameBatch enqueues a DeleteAuthorsByFullName query into batch to be executed
	// later by the batch.
	DeleteAuthorsByFullNameBatch(batch genericBatch, params DeleteAuthorsByFullNameParams)
	// DeleteAuthorsByFullNameScan scans the result of an executed DeleteAuthorsByFullNameBatch query.
	DeleteAuthorsByFullNameScan(results pgx.BatchResults) (pgconn.CommandTag, error)
}

Querier is a typesafe Go interface backed by SQL queries.

Methods ending with Batch enqueue a query to run later in a pgx.Batch. After calling SendBatch on pgx.Conn, pgxpool.Pool, or pgx.Tx, use the Scan methods to parse the results.
