如何使用group_concat引用值

Question

I need to use group_concat to build a list of comma separated values but I need the values to be quoted. How do I do this?

This:

425,254,431,53,513,13,1,13

Should be converted to:

'425','254','431','53','513','13','1','13'

Answer 1

采用：

GROUP_CONCAT(CONCAT('''', your_column, '''' ))

Answer 2

Use MySQL string function QUOTE .

GROUP_CONCAT(QUOTE(`foo`)) `bar`

This will handle cases when the string itself contains a quote.

Answer 3

You can quote the elements before applying GROUP_CONCAT .

SELECT   GROUP_CONCAT(CONCAT('\'', some_column, '\''))
FROM     some_table
