How can I check if an SQL result contains a newline character?

I have a varchar column that contains the string lol\ncats, however, in SQL Management Studio it sho开发者_如何学JAVAws up as lol cats.

How can I check if the \n is there or not?

SELECT *
FROM your_table
WHERE your_column LIKE '%' + CHAR(10) + '%'

Or...

SELECT *
FROM your_table
WHERE CHARINDEX(CHAR(10), your_column) > 0

Use char(13) for '\r' and char(10) for '\n'

SELECT *
FROM your_table
WHERE your_column LIKE '%' + CHAR(10) + '%'

or

SELECT *
FROM your_table
WHERE your_column LIKE '%' + CHAR(13) + CHAR(10) + '%'

For any fellow MySQL users who end up here:

SELECT *
FROM your_table
WHERE your_column LIKE CONCAT('%', CHAR(10), '%')

For me, the following worked just fine in both MySQL Workbench & HeidiSQL (working with MySQL) without having to use the char() variation of \n:

SELECT * FROM table_name WHERE field_name LIKE '%\n%'

In Oracle, try the below command

SELECT * FROM table_name WHERE field_name LIKE ('%'||chr(10)||'%');

SELECT * 
FROM Table 
WHERE PATINDEX('%' + CHAR(13) + CHAR(10) + '%', Column) > 0

SELECT * FROM mytable WHERE mycolumn REGEXP "\n";

select cc.columnname,right(cc.columnname,1),ASCII(right(cc.columnname,1)) ,cc.*
from table_name cc where 
ASCII(right(cc.columnname,1)) = 13

here

• cc.columnname => Column name is column where you want to fine new line or Carriage return.
• right(cc.columnname,1) => this will show only one char what is there at the end. usually it display only blank
• ASCII(right(cc.columnname,1)) => here we get Acii value of that not printable value.

by seeing this ascii value we can conclude which item it is. Example , if this acsci value is 13 then Carriage return , if it is 10 then NEw line we have to use this to filter that record

• cc.* => this gives all the values from the table ( display purpose)
• where ASCII(right(cc.columnname,1)) = 13 => here i found all the values are 13 asci value so filtering ascii value 13

it is working for me .

For any fellow Redshift users who end up here:

select * from your_table where your_column ~ '[\r\n]+'
