SQL, parameter encoder, and row decoder for a statement that returns rows. We assume that sql
has the same number of placeholders of the form $1
, $2
, etc., as the number of slots encoded by encoder
, that sql
selects the same number of columns are the number of slots decoded by decoder
, and that the parameter and column types specified by encoder
and decoder
are consistent with the schema. The check
methods on Session provide a means to verify this assumption.
You can construct a Query
directly, although it is more typical to use the sql
interpolator.
sql"SELECT name, age FROM person WHERE age > $int2".query(varchar *: int2) // Query[Short, (String, Short)]
