我正在尝试使用存储过程在MySQL中以yyyy-mm-dd
格式添加日期值。
如果我在mysql中调用存储过程,则可以正确插入相同的数据。
但是,当我尝试通过java调用它时,出现错误:
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'medication(1005,51,'2' at line 1
我的存储过程是:
CREATE DEFINER=`xxx`@`localhost` PROCEDURE `insert_eD_dispensed medication`(IN `prescription_mapping_id` int(11), IN `patient_id` int(11), IN `date_of_dispense` date )
NO SQL
INSERT INTO `prescription_dispensation_mapping` (`prescription_mapping_id`, `patient_id`, `date_of_dispense` )
电话是:
public boolean insert_eD_dispensation (String prescription_mapping_id, String patient_id, String date_of_dispense) {
Connection conn = this.getDBMySQLCon();
String queryString;
PreparedStatement preparedStmt = null;
try {
queryString = " {CALL insert_eD_dispensed medication(?,?,?)}";
preparedStmt = conn.prepareStatement(queryString);
preparedStmt.setInt(1, toInteger(prescription_mapping_id));
preparedStmt.setInt(2, toInteger(patient_id));
preparedStmt.setDate(3, java.sql.Date.valueOf(date_of_dispense));
preparedStmt.execute();
conn.close();
return true;
} catch (SQLException e) {
e.printStackTrace();
return false;
}
}
java方法的调用是:
String prescription_mapping_id="1005";
String patient_id="1";
String date_of_dispense="2019-06-19";
boolean x = insert_eD_dispensation(prescription_mapping_id, patient_id, date_of_dispense)
