             Summary: camel-sql - Conditionally execute ps.getParameterMetaData() in SqlProducer populateStatement
                 Key: CAMEL-18797
                 URL: https://issues.apache.org/jira/browse/CAMEL-18797
             Project: Camel
          Issue Type: Improvement
          Components: camel-sql
    Affects Versions: 3.19.0, 3.18.4
         Environment: Windows 10

Karaf 4.4.2

OpenJDK 64-Bit Server VM version 11.0.13+8

Camel 3.18.4
            Reporter: John Taylor
             Fix For: 3.18.5, 3.19.0
         Attachments: patchfile.txt

I have a similar problem to the CAMEL-18399 but instead of the result of getParameterMetadata returning null it is throwing an exception from the driver. The driver is com.microsoft.sqlserver/mssql-jdbc/11.2.1.jre11 although all version are affected as far as I can tell. It looks like a bug in their parser where it fails to parse for valid queries when there are parameters. Where it affects me the most is when sql-92 join syntax includes a parameter, like

{{select 'x' from TABLEA A JOIN TABLEB B on A.F1 = B.F1 and B.F2 = :#parm1 WHERE A.F1 = :#parm2}}

Including the parametersCount option doesn't help in this case as it doesn't bypass the getParameterMetadata. My proposal is to only call getParameterMetadata  if the parametersCount isn't set because it is only being used to populate the expected variable anyway.
