Question

我正在尝试使用此文件加载csv文件，但日期格式不正确，因此在插入数据库之前需要重新格式化

if (is_array($file)) {
    foreach ($file as $key => $value) {
        $loadData = sprintf("
            LOAD DATA local INFILE '%s' IGNORE INTO TABLE pos_vs_cognizant CHARACTER SET UTF8 FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"' ESCAPED BY '\"' LINES TERMINATED BY '\\n' IGNORE 1 LINES  
            (
                @store, 
                @business_date, 
                @ns_pos, 
                @ns_cognizant, 
                @ns_variance, 
                @tc_pos, 
                @tc_cognizant, 
                @tc_variance
            ) 
            SET
            id=null,
            store=@store,
            business_date=STR_TO_DATE(@business_date, '%d-%b-%y'),
            ns_pos=@ns_pos,
            ns_cognizant=@ns_cognizant,
            ns_variance=@ns_variance,
            tc_pos=@tc_pos,
            tc_cognizant=@tc_cognizant,
            tc_variance=@tc_variance,
            unique_row=CONCAT(STR_TO_DATE(@business_date, '%d-%b-%y'),'_',@store,'_',@ns_pos,'_',@tc_pos),
            created_at=now()
        ", addslashes($value));

        if (DB::connection()->getpdo()->exec($loadData)) {
            $response['status'] = 'success';
            //echo'tes';
        } else {
            $response['status'] = 'error';
            //echo'ayaw';
        }
    }
}else{
    //echo'wala nangyre';
}

发生的事情是'％'sprintf出现问题，所以我所做的是在没有sprintf的情况下尝试使用它，但是它抛出了mysql语法错误，并且我已经尝试过更改转义符，将其括起来并终止仍然不起作用。

是否还有其他方法可以将那些日期“ dd-mm-yy”转换为“ YYYY-mm-dd”或在没有sprintf的情况下插入？

将%%用于%格式字符串中的文字sprintf()字符。

    $loadData = sprintf("
        LOAD DATA local INFILE '%s' IGNORE INTO TABLE pos_vs_cognizant CHARACTER SET UTF8 FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"' ESCAPED BY '\"' LINES TERMINATED BY '\\n' IGNORE 1 LINES  
        (
            @store, 
            @business_date, 
            @ns_pos, 
            @ns_cognizant, 
            @ns_variance, 
            @tc_pos, 
            @tc_cognizant, 
            @tc_variance
        ) 
        SET
        id=null,
        store=@store,
        business_date=STR_TO_DATE(@business_date, '%%d-%%b-%%y'),
        ns_pos=@ns_pos,
        ns_cognizant=@ns_cognizant,
        ns_variance=@ns_variance,
        tc_pos=@tc_pos,
        tc_cognizant=@tc_cognizant,
        tc_variance=@tc_variance,
        unique_row=CONCAT(STR_TO_DATE(@business_date, '%%d-%%b-%%y'),'_',@store,'_',@ns_pos,'_',@tc_pos),
        created_at=now()
    ", addslashes($value));

PHP：转换日期格式时，使用sprintf加载数据文件时出现'％'问题
