PowerBuilder中使用JDBC连接MYSQL 无法使用COUNT(*) MAX() 函数的处理

PowerBuilder中应用JDBC衔接MYSQL 

遇到的毛病：

 long ll_count 
// Profile mysql
SQLCA.DBMS = "JDBC"
SQLCA.LogPass = "123"
SQLCA.LogId = "root"
SQLCA.AutoCommit = False
SQLCA.DBParm = "Driver="com.mysql.jdbc.Driver",URL="jdbc:mysql://localhost:3306/his" " 
connect using sqlca; 

select count(*) into :ll_count from yk_cddz; long ll_count
