---------------------------------------
Summary: Sql should accept wildcard parameters
Key: GROOVY-11541
URL: https://issues.apache.org/jira/browse/GROOVY-11541
Project: Groovy
Issue Type: Improvement
Components: SQL processing
Affects Versions: 5.0.0-alpha-11
Reporter: Sergey Chernov
`groovy.sql.Sql` declares several methods with SQL statement and parameters
like this
```
public boolean execute(String sql, List<Object> params) throws SLQException {
```
This declaration has one major drawback: it's not possible to pass as an
argument the List which is not exactly `List<Object>`, e.g. `List.of(1)`.
This List is only iterated, hence using wildcard here is safe. Also changing
the type to wildcard as receiving argument should be binary compatible.
Suggested method signature (example; address all such methods of Sql class):
```
public boolean execute(String sql, List<?> params) throws SLQException {
```
Additional notes:
* there are few methods that return `List<Object>`, e.g.
`SqlWithParams.getParams()` - in this case the Object generic should be
preserved.
* For reference: pretty similar problem solved for cassandra-java-driver
