Function QueryCatalog

adapter/adapter.go:78–84

QueryCatalog is a helper function to query the catalog, such as information_schema. Unlike QueryContext, this function does not require a schema name to be set on the connection, and the current schema of the connection does not matter.

(ctx *sql.Context, query string, args ...any)

// Unlike QueryContext, this function does not require a schema name to be set on the connection,

func QueryCatalog(ctx *sql.Context, query string, args ...any) (*stdsql.Rows, error) {
	conn, err := ctx.Session.(ConnectionHolder).GetCatalogConn(ctx)
	if err != nil {
		return nil, err
	}
	return conn.QueryContext(ctx, query, args...)
}

func QueryRowCatalog(ctx *sql.Context, query string, args ...any) *stdsql.Row {
	conn, err := ctx.Session.(ConnectionHolder).GetCatalogConn(ctx)
