我在一列中有以下电话号码:
["+63(02)3647766", "+63(02)5467329", "+63(02)8555522", "+63(02)3642403"]
我怎样才能得到这样的信息:
+63(02)3647766,+63(02)5467329,+63(02)8555522,+63(02)3642403

我认为这是最唯一的 MySQL 清洁方式,至少对于 8 以下的 MySQL 版本
询问

你听说过 JSON_TABLE() 吗?– 牡蛎
我有,我不认为每个人都已经在 MySQL 8 上,但为了完整性我也添加了它。
仅 MySQL 8.0 查询
SET SESSION group_concat_max_len = @@max_allowed_packet;
SELECT
GROUP_CONCAT(item)
FROM JSON_TABLE(
'["+63(02)3647766", "+63(02)5467329", "+63(02)8555522", "+63(02)3642403"]'
, "$[*]"
COLUMNS (
rowid FOR ORDINALITY
, item VARCHAR(100) PATH "$"
)
) AS json_parsed
结果
| GROUP_CONCAT(item) |
| ----------------------------------------------------------- |
| +63(02)3647766,+63(02)5467329,+63(02)8555522,+63(02)3642403 |

REPLACE()
嵌套方法比较麻烦,但应该适用于所有 MySQL 版本。
SELECT
REPLACE(
REPLACE(
REPLACE(
'["+63(02)3647766", "+63(02)5467329", "+63(02)8555522", "+63(02)3642403"]'
, '['
, ''
)
, ']'
, ''
)
, '"'
, ''
)
结果

所以如果你有替换替换替换功能。它超级酷而且简单。如果要构建以逗号分隔的 varchar 值,请使用以下命令;
@json_array = ["value1", "value2"]
select replace(replace(replace(json_extract(@json_array, '$'), '"', '\''), '[', ''), ']', '');
但是如果你想建立数字然后使用
select replace(replace(replace(json_extract(@json_array, '$'), '"', ''), '[', ''), ']', '');enter code here
最适合所有 MySQL 版本的解决方案是:
SELECT
REPLACE(
REPLACE(
REPLACE(
records.json,
'[',
''
),
']',
''
),
'"',
''
) AS comma_separated
FROM (
SELECT
'["+63(02)3647766", "+63(02)5467329", "+63(02)8555522", "+63(02)3642403"]' AS json
) AS records;
看起来很重,但它就像一个魅力。
如果不是您要在此处执行的查询是一个简单的函数,您可以传递您的数组并取回字符串。
$data = ["+63(02)3647766", "+63(02)5467329", "+63(02)8555522", "+63(02)3642403"];
function MakeAstring($data){
$array_with_comma = array();
$last_key = end(array_keys($data));
foreach($data as $key => $number)
{
$string .= $number.($key != $last_key ? ',': '');
}
return $string;
}
echo MakeAstring($data);
