When developing code in TSQL, we may need to delete the last character of a string in some cases.<\/p>\n

The other day, I used the “,” brace to combine the strings in a column. At the end, a value was generated as follows.\u00a0The article name is: “How To Concatenate Query Results in SQL Server(TSQL)<\/a>”<\/p>\n

1,2,3,4,5,<\/pre>\n
That’s why I had to delete the last character of all data in the column.<\/p>\n
Example:<\/strong><\/p>\n
We are creating a table as follows and we are adding a few records to this table.<\/p>\n
CREATE TABLE [dbo].[DeleteLastCharacter](\n[myString] [varchar](50) NULL\n) ON [PRIMARY]\nGO\nINSERT INTO [dbo].[DeleteLastCharacter] VALUES('1,2,3,4,5,'),('ANKARA,ISTANBUL,IZMIR,')<\/pre>\n
When we read the data from the table, we see that the last characters are “,” as you see below.<\/p>\n
Select * FROM [dbo].[DeleteLastCharacter]<\/pre>\n
\"\"<\/p>\n
With the help of the following script, in order to test the script, we read the data whose last characters have been deleted.<\/p>\n
SELECT LEFT(MyString,DATALENGTH(MyString)-1) FROM [dbo].[DeleteLastCharacter]<\/pre>\n
\"\"<\/p>\n
After making sure that the script is correct, we delete the last character of the data in the column with the help of the following script.<\/p>\n
UPDATE [dbo].[DeleteLastCharacter] SET myString=LEFT(myString,DATALENGTH(myString)-1)\nGO\nSELECT * FROM [dbo].[DeleteLastCharacter]<\/pre>\n
