PostgreSQL ("PG") supports the notion of placeholders, as do many other relational databases. The placeholder notation in PG uses $X within the SQL. For example:
select foo
from bar
where bletch = $1
is valid SQL. The doller-notation allows re-use of positional parameters and avoids SQL injection entirely by placing the input is appropriately-typed buffers w/in the SQL statement handler. It also avoids issues with double-interpolating quotes as the placeholders are not literals and do not require SQL-quoting to be interpolated properly.
We have quite a bit of SQL here that has to be shared between Python and other packages, so using standard PG SQL statements is required.
Q: Is there any way to prepare and execute standard PG SQL statements with dollar placeholders in PsychoPG2?
Thanks
