“操作“ concat”的排序规则的非法混合”在数据库导入后出现 [英] "Illegal mix of collations for operation 'concat'" appears after data base import

问题描述

在我的旧站点中，此问题不存在。但是，在我更改服务器并导入数据库之后，将出现此消息。 PHP版本是5.3，这是代码：

In my old site, this problem does not exist. But after I have changed the server and imported the data base, this message appears. The PHP version is 5.3 and this is the code:

$sql = "SELECT * FROM movcaixa 

    WHERE data BETWEEN '$data1' AND '$data2' AND empresa = $empresa 

    ORDER BY data ASC";
   $resMovCaixa = mysql_query($sql, $cnn) or die('Falha na conexão com o banco de dados');
   $sql = "SELECT cp.id AS codigo, CONCAT('Pagamento ref. a ', des.descricao, ', conforme doc. nº ',  cp.documento) AS hist, DATE_FORMAT(cp.quitacao, '%d/%m/%Y') AS data, cp.valorpago AS vlr, cp.documento AS doc, fr.nome AS forn, des.descricao AS desp 

    FROM contaspagar cp, fornecedor fr, despesa des 

    WHERE cp.fornecedor = fr.id AND cp.despesa = des.id AND cp.quitacao BETWEEN '$data1' AND '$data2' AND empresa = $empresa 

    ORDER BY data ASC";
    $resContasPagar = mysql_query($sql, $cnn) or die(mysql_error($cnn));
    $sql = "SELECT cr.id AS codigo, DATE_FORMAT(cr.quitacao, '%d/%m/%Y') AS data, CONCAT('Recebimento ref. ', cli.nome, ', conforme doc. ', cr.documento) AS hist, cr.valorpago AS vlr, cr.documento AS doc, cs.descricao AS cont 

    FROM contasreceber cr, contratoservico cs, cliente cli 

    WHERE cr.contratoservico = cs.id AND cs.cliente = cli.id AND cr.quitacao BETWEEN '$data1' AND '$data2' AND empresa = $empresa 

    ORDER BY cr.quitacao";

有人可以帮我吗？

推荐答案

检查表的排序规则，然后在CONCAT函数中使用：

Check the collations for the tables, you use inside CONCAT function:

1. des


2. cp


3. cli


4. cr

1. des
2. cp
3. cli
4. cr

对所有它们使用相同的排序规则。

Use the same collation for all of them.
