From a user experience perspective, we have this issue which has
parameterized queries like:
```
ctx.sql("select c_custkey, c_name from {df}", df=df_customer)
```
And the similar query for direct injection would be
```
ctx.sql("select c_custkey, c_name from df_customer")
```
As Matt points out above we could potentially do replacement of things other
than table names with the parameterization.
From an implementation perspective, the parameterization approach searches
any SQL command for `{}` and matching named arguments and does a replacement
with their string equivalent of their logical plan.
The direct injection tries to execute the SQL command, and on failures then
tries to find objects that can be table providers.
