To correctly format the inputs for your SQL function when using `jdbcTemplate`, you'll need to ensure that the parameters you pass match the expected data types in the SQL function. In your case, you want to call `fct_get_etablissement_infos(?, ?)`, where both parameters are strings. Here’s how to do it step-by-step:
### Step-by-Step Solution:
1. **Understand the Function Signature**:
- The function `fct_get_etablissement_infos` takes two parameters. Based on your requirement, both parameters need to be strings.
2. **Prepare the SQL Query**:
- You already have the SQL query prepared as:
```java
String sql = "SELECT * FROM fct_get_etablissement_infos(?, ?)";
```
3. **Pass the Parameters**:
- When calling the `jdbcTemplate.query`, you need to ensure that the parameters you pass are formatted as strings, even if they represent numeric values.
- You should convert your parameters to strings before passing them to the query.
4. **Example Code**:
- Here’s how you can implement this:
```java
String codsirentStr = String.valueOf(codsirent);
String numitnclaetbStr = String.valueOf(numitnclaetb);
return jdbcTemplate.query(sql, new Object[]{codsirentStr, numitnclaetbStr}, rs -> {
if (rs.next()) {
Etablissement etablissement = new Etablissement();
etablissement.setCodsirent(rs.getString("codsirent"));
etablissement.setNumitnclaetb(rs.getString("numitnclaetb"));
etablissement.setNumtecprs(rs.getLong("numtecprs"));
etablissement.setNumtecadrcmm(rs.getLong("numtecadrcmm"));
// Add other fields as necessary
return etablissement;
}
return null; // Return null if no result is found
});
```
### Additional Notes:
- **Data Type Conversion**:
- Make sure to convert numeric values to strings using `String.valueOf()` or by concatenating with an empty string (e.g., `codsirent + ''`). This ensures they're treated as strings in the SQL query.
- **Error Handling**:
- Consider adding error handling for cases when the query doesn't return results or when inputs are invalid.
### Conclusion:
Using the `jdbcTemplate` with string formatting for your SQL function parameters is essential for ensuring the query executes correctly. By following these steps, you should be able to run your desired SQL function successfully.
