如何在条件条件column_name ='bolt 1/2 inch'的情况下在php mysql查询中搜索

Question

I have a column in a db table that contains 'bolt 1/2 inch'

i got hanged when passing forward slash in the variable. If there is no slash then it code is working fine.

$par_stockDescription = 'bolt 1/2 inch'
$description = mysql_real_escape_string($par_stockDescription);

$sql_getStockId = "SELECT stock_id,units FROM table_name WHERE description ='".$description ."';

$result_stockId =db_query($sql_getStockId);
$arr_stockId = db_fetch($result_stockId);
echo  $arr_stockId['stock_id']; 

Answer 1

您的字符串配额不正确，请使用以下命令：

$sql_getStockId = "SELECT stock_id,units FROM table_name WHERE description ='".$description ."'";

Answer 2

将查询更改为以下内容

$sql_getStockId = "SELECT stock_id,units FROM table_name WHERE description ='".$description ."'";

Answer 3

This should be your query:

$sql_getStockId = "SELECT stock_id,units FROM table_name WHERE description ='".$description ."'";

Also mysql_real_escape_string has been deprecated consider mysqli or pdo
