I think this...

List<List<Object>> keys = mdds.executeInsert(params, mdSqlString);

should be this....

List<List<Object>> keys = mdds.executeInsert(mdSqlString, params);

from the groovy sql source....

    public List<List<Object>> executeInsert (String sql, List<Object> params) throws SQLException {

        Connection connection = createConnection();

        PreparedStatement statement = null;

        try {

            statement = getPreparedStatement(connection, sql, params, 1);

            this.updateCount = statement.executeUpdate();

            ResultSet keys = statement.getGeneratedKeys();

            return calculateKeys(keys);


        catch (SQLException e) {

            throw e;


        finally {

            closeResources(connection, statement);

Subject: Trouble with groovy.sql

I'm using the groovy.sql libraries inside of a Java program and having trouble with parameter substitution. My code looks like this:

Map<String, Object>params = new HashMap<String, Object>();
params.put("source_system_id", Integer.valueOf(6));
params.put("rec_loc_txt", "Test" + randomNum.toString());
params.put("created_dt_tm", jts);
String mdSqlString = "INSERT INTO MD_CATALOG " +
                 "      (SOURCE_SYSTEM_ID, REC_LOC_TXT, CREATED_DT_TM)" + 
                 "      VALUES" + 
                 "      (:source_system_id, :rec_loc_txt, :created_dt_tm)";

try {
List<List<Object>> keys = mdds.executeInsert(params, mdSqlString);
} catch (SQLException e) {
// TODO Auto-generated catch block

But, when it runs, I get an exception thrown that says:

Exception in thread "main" java.lang.IllegalArgumentException: Found 4 parameter placeholders but supplied with 3 parameters
at groovy.sql.Sql.setParameters(Sql.java:4116)
at groovy.sql.Sql.getPreparedStatement(Sql.java:4394)
at groovy.sql.Sql.executeInsert(Sql.java:2610)
at groovy.sql.Sql.executeInsert(Sql.java:2674)
at org.mitre.mac.Main.main(Main.java:70)

Now, I only see 3 placeholders for my 3 parameters. Can anyone tell me where I'm going wrong?
