将搜索从SQL Server转换为MySQL

我需要将这个从SQLServer转换成MySQL

IF IsNull(@SearchText, '') <> '' BEGIN
SET @SearchText = '%' + @SearchText + '%'

SELECT NewsID,DeptID,DeptName,Title,Details ,NewsDate,img 
FROM @tbSearchtextTb
WHERE IsNull(Title,'')+IsNull(Details,'') LIKE @SearchText END

还有很多其他的方法，但我找不到

因此，如果您知道，请让我知道，谢谢并致以最良好的问候。

您可以在mysql中使用全文搜索

SQL Server版本也可以编写为：

IF @SearchText <> '' -- null is implicitly <> ''
BEGIN

SELECT NewsID,DeptID,DeptName,Title,Details ,NewsDate,img 
FROM @tbSearchtextTb
WHERE IsNull(Title,'')+IsNull(Details,'') LIKE '%' + @SearchText + '%'

END

IsNull在MySQL中是IFNull。 在MySQL中使用Concat连接字符串 空值在concat中是隐式的

IF SearchText <> '' THEN  # << again, this test is sufficient
    SELECT
        CatID,CatTitle,CatDescription,CatTitleAr,CatDescriptionAr,
        PictureID,Published,DisplayOrder,CreatedOn
    FROM tmp
    WHERE Concat(CatTitle, CatDescription, CatTitleAr, CatDescriptionAr)
    LIKE Concat('%',$SearchText,'%');

这是我一直在寻找的令人惊讶的答案。非常感谢你的帮助。

IF @SearchText <> '' -- null is implicitly <> ''
BEGIN

SELECT NewsID,DeptID,DeptName,Title,Details ,NewsDate,img 
FROM @tbSearchtextTb
WHERE IsNull(Title,'')+IsNull(Details,'') LIKE '%' + @SearchText + '%'

END

IF SearchText <> '' THEN  # << again, this test is sufficient
    SELECT
        CatID,CatTitle,CatDescription,CatTitleAr,CatDescriptionAr,
        PictureID,Published,DisplayOrder,CreatedOn
    FROM tmp
    WHERE Concat(CatTitle, CatDescription, CatTitleAr, CatDescriptionAr)
    LIKE Concat('%',$SearchText,'%');
