[英]SQL node.js Syntax error on what seems to be a valid query?
我正在對表進行更新以設置位置。 我已經提取了查詢並在數據庫上手動運行它,並且運行良好,但是當通過connection.query()傳遞時,似乎認為node.js控制台中存在語法錯誤。
function sendShipPosition(position) {
var input = '';
if (position.moving === true) {
var currentdate = new Date();
var datetime = currentdate.getFullYear() + "-"
+ (currentdate.getMonth()+1) + "-"
+ currentdate.getDate() + " "
+ currentdate.getHours() + ":"
+ currentdate.getMinutes() + ":"
+ currentdate.getSeconds();
var input = ', moving_datetime = ' + datetime;
}
connection.query('UPDATE ships SET x_axis = :x, y_axis = :y' + input + ' WHERE ship_id = :ship_id'), {
x: parseInt(position.x),
y: parseInt(position.y),
ship_id: 1
};
}
這是語法錯誤:
這是“位置”變量的輸入數據值:
{ x: '-605', y: '-257', moving: 0 }
我希望我不要太笨拙,對質量低劣的問題感到抱歉。
謝謝
此函數將生成SQL代碼,該SQL代碼缺少datetime
變量周圍的引號,從而導致無效的SQL代碼。
function sendShipPosition(position) {
var input = '';
if (position.moving === true) {
var currentdate = new Date();
var datetime = currentdate.getFullYear() + "-"
+ (currentdate.getMonth()+1) + "-"
+ currentdate.getDate() + " "
+ currentdate.getHours() + ":"
+ currentdate.getMinutes() + ":"
+ currentdate.getSeconds();
# Here!
var input = ', moving_datetime = \'' + datetime + '\''
}
connection.query('UPDATE ships SET x_axis = :x, y_axis = :y' + input + ' WHERE ship_id = :ship_id'), {
x: parseInt(position.x),
y: parseInt(position.y),
ship_id: 1
};
}
