Update One column value in another column in Mysql
Hi,
For updating Value from one column to another use this
update Table_name set Column_name1 = Column_name2
But if you want to copy specified character from a column then
update Table_name set Column_name1 =
(
SELECT LEFT(Column_name2,INSTR(Column_name2,",")-1)
)
SELECT LEFT(Column_name2,INSTR(Column_name2,",")-1)
This query will select only characters before ,(Comma).
You can modify it as per your requirement.You can use slash or any other character...
Thanks
Shakun
