Grails call stored procedure with output parameter

Question

how to call an Oracle procedure with paramters in grails, the produre looks like this,

var returntype number; begin IZMST_PKG_SOLO_GENERATE_SQL.pro_get_row_cnt(1,181,:returntype); end;

I have tried to call this procedure but the program encounter an error, you can check the error message as below.

org.apache.commons.dbcp.DelegatingCallableStatement with address:
    "oracle.jdbc.driver.OracleCallableStatementWrapper@52d0d407" is
    closed.. Stacktrace follows: java.sql.SQLException:
    org.apache.commons.dbcp.DelegatingCallableStatement with address:
    "oracle.jdbc.driver.OracleCallableStatementWrapper@52d0d407" is
    closed.     at

pasted a piece of the code

Connection conn = dataSource.getConnection()
            Sql sql = new Sql(conn)
            //int test  = sql.call("",)
            sql.call'BEGIN  IZMST_PKG_SOLO_GENERATE_SQL.pro_get_row_cnt(?,?,?); END;',[1L,qryId,Sql.resultSet(OracleTypes.NUMBER)],{dwells-> 
                println dwells
            }

PS: this problem has been solved, update the description to make this question easier to understand.

Answer 1

If I understood, your return type is number, so your can use directly Sql.NUMERIC.

sql.call '{call IZMST_PKG_SOLO_GENERATE_SQL.pro_get_row_cnt(?,?,?) }',[1L, qryId, Sql.NUMERIC],{ dwells -> 
  println dwells
}
