MYSQL - 准备stmt并执行stmt并添加WHERE和LIKE

Question

我试图构建下一个存储的proc，但它不工作。

PREPARE STMT FROM 'SELECT a, b, c, d, e FROM TABLE_1 WHERE (`a` like `%?%` OR `b` like `%?%` OR `c` like `%?%` OR `d` like `%?%` OR `e` like `%?%`) LIMIT ?, ?'; 
EXECUTE STMT USING @search, @skip, @rows; 

基本上，我试图搜索一列内的字符串，并返回适合列的行。 请帮我解决这个问题，因为我得到了一个错误：

Unknown column '%?%' in 'where clause' 

Answer 1

这是因为多少？应该等于USING条款后的参数个数。你也有错误的报价？而不是"?"尝试：

PREPARE STMT FROM 'SELECT a, b, c, d, e FROM TABLE_1 WHERE (`a` like "%?%" OR `b` like "%?%" OR `c` like "%?%" OR `d` like "%?%" OR `e` like "%?%") LIMIT ?, ?'; 

EXECUTE STMT USING @search, @search, @search, @search, @search, @skip, @rows; 

，或者尝试

SET @query1 = CONCAT(' 
    SELECT SQL_CALC_FOUND_ROWS a, b, c, d, e 
    FROM TABLE_1 
    WHERE (`a` like "%',@search,'%" OR 
     `b` like "%',@search,'%" OR 
     `c` like "%',@search,'%" OR 
     `d` like "%',@search,'%" OR 
     `e` like "%',@search,'%") 
    LIMIT ',@skip,', ',@rows,''); 

    PREPARE stmt FROM @query1; 
    EXECUTE stmt; 
    SELECT FOUND_ROWS() AS total_rows; 
    DEALLOCATE PREPARE stmt; 

Answer 2

给出的例子在MySQL似乎表明问号 的数量应该是参数计数相似？

http://dev.mysql.com/doc/refman/5.0/en/sql-syntax-prepared-statements.html

我错了？

在你的情况下，这意味着七个问号和七个参数。

所有最好的

Answer 3

尝试......

PREPARE STMT FROM 'SELECT a, b, c, d, e FROM TABLE_1 WHERE (`a` like "%?%" OR `b` like "%?%" OR `c` like "%?%" OR `d` like "%?%" OR `e` like "%?%") LIMIT ?, ?'; 

EXECUTE STMT USING @search, @search, @search, @search, @search, @skip, @rows; 

注意

的变量数应该等于我们有问号的数量。

你有7个问号，只有3个变量。所以错误发生在第四个?。
