Question

I need to write a stored procedure for which the input is a string.

The input string contains variable names and their values separated by pipeline delimiter like this:

Name =Praveen | City=Hyderabad | Mobile=48629387429| Role=User| etc

In the stored procedure I have declared variables like @x, @y, @z, @t to obtain values as

@x=Praveen (Name value)
@y=Hyderabad (City Value)
@z=48629387429(Mobile Value)
@t=User(Role Value)

Also input string can have the values in any order like

City=Hyderabad | Mobile=48629387429 | Role=User | Name =Praveen |etc

Once I parse the values into @x, @y, @z, @t etc I have to use these values in the stored procedure.

Kindly let me how I can parse the input string to obtain the values of Name, City, Mobile, Role into @x, @y, @z and @t respectively.

One possible solution is use XML

DECLARE @text VARCHAR(1000) 
        ,@xml xml

SELECT @text = 'City=Hyderabad | Mobile=48629387429 | Role=User | Name =Praveen'

SELECT @text = REPLACE(@text,'|','"')
    ,@text = REPLACE(@text,'=','="')
    ,@text = '<row ' + @text + '"/>'

SELECT @xml = CAST(@text AS XML)

select 
    line.col.value('@Name[1]', 'varchar(100)') AS Name
    ,line.col.value('@City[1]', 'varchar(100)') AS City
    ,line.col.value('@Mobile[1]', 'varchar(100)') AS Mobile 
    ,line.col.value('@Role[1]', 'varchar(100)') AS Role 
FROM @xml.nodes('/row') AS line(col)
