[syahiaoui]

Hi,
I would like to call stoted function using teradata, and the result expected is Clob, but i got an empty array depending the function used;
The stored function used:
let sql = CALL DEV.MY_PROC(:data,OUT_RESULT)

return db.readPreparedStatement(sql, [db.createPreparedStatementParam('data', 'String', data)]);

The results is:
{
"success": true,
"data": []
}
More informations:

Nodejs: 10.0.0
NPM: 6.1.0
OS: Ubuntu
Database: Teradata
